Introduction

Once the President’s Commission on Americans Outdoors reviewed the nation’s policies on activities in 1985, the social, economic, and environmental advantages of recreation were recognized, but little attention was paid to human health advantages. Since then, however, studies have confirmed a link between exercise that takes place outdoors and positive health outcomes-and also a connection between an inside, sedentary lifestyle and negative health consequences.

Additionally there is evidence that both being outdoors and viewing natural scenes can help to eliminate stress. The links are sufficiently strong enough that researchers and practitioners in medical fields are actually beginning to identify parks and recreation like a health service. Outdoor recreation’s contribution to health can be viewed as in the context of ?wellness. The planet Health Organization (2003) defines health as ?a situation of complete physical, mental and social well-being and never merely the lack of disease or infirmity.

This definition moves from the strictly medical type of health toward the idea of well-being. The Alberta Centre for Wellness (1989) finds that ?the idea of well-being or optimal health and wellness involves a fragile balance among physical, emotional, spiritual, intellectual and social health and then lists an array of dimensions, from fitness, nutrition, and stress management to meditation, education, and relationships. Activities touches on those aspects of health insurance and can enhance not just physical health but additionally emotional well-being.

Just being outdoors, for instance, has been shown to confer health advantages. The research literature on activities as it pertains to human health is vast and growing. To assist policymakers take these new and emerging findings into consideration when designing recreation and park services and initiatives for that 21st century, this paper summarizes the salient issues. Throughout, your reader will find questions that identify research gaps-an indication the subject area is fertile ground for further attention.

Section 2 considers how being outside in natural surroundings may improve health, and Section 3, how outdoor activities benefit participants. Section 4 examines children’s health problems-obesity and hyperactivity in particular-that could be mitigated through outdoor play, sports, and nature study. Section 5 describes methods to measuring exercise and recent trends in park visitation and outdoor activity participation, and Section 6 compares the many variables affecting people’s participation in outdoor activities. Section 7 considers the projected demographic changes which will affect policymaking within this arena.

The concluding section brainstorms policy options. Residing in comparatively natural areas, viewing nature, and achieving outdoor recreation areas and facilities nearby seem to provide health advantages: …the major determinants of health might have little related to the healthcare system (Hancock 1999) and public health have to focus on the environmental and social facets of health (Chu and Simpson 1994). Publicly owned natural spaces are a perfect resource to aid these along with other aspects of human health insurance and well-being. (Maller et al. 2005, 5) That assertion is dependant on anthropological understanding.

Humans evolved for any life put in small groups, hunting and gathering around the plains of Africa. Natural selection hasn’t had time for you to revise the body for coping with fatty diets, automobiles, artificial light, and heating. This mismatch between our design and today’s environment may take into account many preventable modern diseases (Nesse and Williams 1996). The landscapes we discover preferable may reflect our origins.

Of all of the possible landscapes, the African savanna-grassy plains interspersed with spreading, mature trees, usually with water present-is typically the most popular: ?So well will we love the savanna that people have recreated everything over the globe within the wide tree canopies and insufficient undergrowth found in the Japanese Zen garden, the English landscape, and also the American city park (Knize 1998, 132). Historically, public parks and activities areas, specifically in cities, were produced for health purposes. Through the 1890s, landscape architects and park planners were worried about sedentary lifestyles.

The 19th-century Rational Recreation movements sought to encourage types of leisure considered superior-and connection with nature would be a primary component. Parks were the ?lungs from the city (Cranz 1982). The benefit of contact with nature was articles of faith. Today those health advantages are being quantified, and scientific scientific studies are documenting the reality of what 19th-century planners believed.

Overall health Benefits of Natural Spaces

There’s increasing evidence that closeness towards the natural environment is good. One study discovered that living in an environmentally friendly environment was positively associated with such health indicators as stress levels and quantity of physical activity; the connection between green space and health indicators was somewhat stronger at a lower price educated people (de Vries et al. 2003). One health benefit of being outdoors today is the fact that being indoors may pose greater dangers, since pollution exposure in homes and offices is usually greater than outdoors.

The California Air Resources Board estimates that indoor air pollutant levels are 25 to 62 percent more than outside levels and may pose serious health problems1. Moreover, when indoors in your own home, people are more prone to snack. Medium and TV viewership is assigned to snacking more often, and frequent viewers also report more use of energy-dense snacks (Thomson et al. 2008). Thus, one advantage of outdoor recreation, from the health perspective, is really a decreased probability of overeating and suffering pollution-related health issues. And of course, while outdoors, individuals are less likely to become sedentary.

Stress and also the Environment

Based on the American Institute of Stress (2002), 43 percent of U.S. adults experience adverse health problems due to acute or chronic stress. Moreover, approximately 75 percent of visits to primary care physicians are for stress-related complaints and disorders. Individuals with high levels of stress are more in danger of the common cold, cardiac arrest, and cancer. Stress has additionally been linked to obesity, high systolic blood pressure level, and elevated heart rates (Bell et al. 1998; Brand et al. 2000).

Mental stress can decrease blood circulation to the heart. Circulation, the journal from the American Heart Association, has called stress a risk factor for heart disease patients. Migraines, rheumatoid arthritis, chronic fatigue, receptiveness to allergies, along with other maladies will also be related to chronic stress. Stress may both suppress the body’s defense mechanisms and result in hormonal imbalances that increase manufacture of abnormal cells. Stress is especially problematic for seniors, since aging is combined with physical, psychological, and social changes.

Age-related changes-from chronic disease and disability to care-giving responsibilities and lack of a loved one-are potential stressors (Baltes and Baltes 1990). Some investigation has shown this too much ?artificial stimulation and time put in purely human environments could cause exhaustion along with a loss of vitality and health (Katcher and Beck 1987; Stilgoe 2001).

The requirements of everyday life-commuting, work, complex decisions- cause a lack of attention, a state seen as a inattentiveness, irritability, and impulsiveness. ?In comparison, according to Kuo and Sullivan (2001, 545), ?natural settings and stimuli for example landscapes and animals appear to effortlessly engage our attention, allowing us to go to without paying attention. That the physical environment can trigger human aggression is well-established. Crowding, high temperatures, and noise have been associated with aggression and violence (Kuo and Sullivan 2001). High levels of stress are related to youth violence. Some think that stress produces ?social illness -pathological responses for example violent and reckless behaviour, crime, or substance abuse.

Antisocial behaviour is a very common reaction to stressful life situations. Spending some time in nature as well as viewing nature seems to reduce stress, however, and therefore contact with nature may reduce aggression and violence (Kaplan 1995). Rejuvenating effects happen to be associated with natural settings, including wilderness areas (Hartig et al. 1991; Kaplan 1984), prairies (Miles et al. 1998), community parks (Canin 1991; Cimprich 1993), as well as rooms with houseplants (Lohr et al. 1996).

Numerous studies find speedier time to recover from injury through contact with plants or nature, fewer illnesses imprisonment inmates whose cell windows face nature, and calming results of viewing natural landscape images after individuals are stressed (e.g., Frumkin 2001; Moore 1981; Ulrich 1984; Parsons et al. 1998). Empirical, theoretical, and anecdotal evidence shows that contact with nature positively affects blood pressure level, cholesterol, lifestyle, stress reduction, and behavioural problems among children (Moore 1981; Kaplan and Kaplan 1989; Hartig et al. 1991; Ulrich et al. 1991a, 1991b; Kaplan 1993; Rohde and Kendle 1997; Leather et al. 1998; Parsons et al. 1998; Frumkin 2001). These outcomes have particular relevance for mental health insurance and cardiovascular disease, that are expected to get to be the two biggest contributors to disease worldwide through the year 2020 (Murray and Lopez 1996).

3. Health advantages of Activities

Outdoor recreation plays a role in wellness mostly through prevention, and also the most beneficial outdoor pursuits are the ones that end up part of one’s life, done regularly. Many participants attempt a ?career in a specific activity, increasingly devoted to it and adapting their participation to changing life circumstances (e.g., Bryan 1970; Stebbins 1992). Research question: It is possible to link between activities ?careers and positive health consequences that will demonstrate the advantages of long-term, serious involvement in activities?

General Health Advantages of Outdoor Activity

Activities often comprises several types of activity. Watching birds, for example, may involve walking, interpreting sounds and visual clues, and socializing with fellow birdwatchers; all these has its wellness implications. Walking is a very common denominator for most types of outdoor recreation. Brisk walking just for three hours per week or 30 minutes each day is assigned to a Thirty to forty percent lower chance of heart disease in females (AARP 2008, citing the 20-Year Nurses’ Health Study).

Walking can have many health advantages for seniors: managing weight; controlling blood pressure level; decreasing chance of heart attack; boosting ?good cholesterol; lowering chance of stroke; reducing chance of breast cancer and kind 2 diabetes; avoiding requirement for gallstone surgery; avoiding hip fracture; preventing depression, colon cancer, constipation, osteoporosis, and impotence; lengthening lifespan; lowering levels of stress; relieving arthritis and lower back pain; strengthening muscles, bones, and joints; improving sleep; and elevating overall mood and feeling of well-being.

Thus, any outdoor pursuit which includes walking can bring about overall health and wellness. Researchers going through the relations between activities participation and wellness have discovered beneficial effects on two problems particularly, stress and obesity.

Stress and Activities

Stress reduction seems to be an important benefit reported by older people to local parks. Negative moods decrease after working time in a park, and park users report ‘abnormal’ amounts of anxiety and sadness (Many Payne 1978). The more people remain at a park, the less stressed they report feeling (Hull and Michael 1995).

A national telephone survey of just one,300 households discovered that the benefits the American public most often associated with utilization of recreational services were exercise and fitness; relaxation and ?peace (reducing stress) were the 2nd most frequently mentioned. One study according to self-reported stress found statistically significant relationships between your use of urban green spaces and reducing stress, regardless of the respondent’s age, sex, or socioeconomic status.

The outcomes suggest that the greater often a person visits urban green spaces, the more infrequently he or she reports stress-related illnesses (Grahn and Stigsdotter 2003). Some research has addressed the bond between reducing stress and activities more quantitatively, by measuring cortisol levels.

Research using cortisol testing provides evidence that park-based leisure, daily stress, and health are significantly, if modestly, related (Orsega-Smith et al. 2004). Other measures used include galvanic skin response, blood pressure level, EEG, and muscular tension. Research questions: As to the extent are high and chronic levels of stress affected by activities? What is the relative need for the natural environment, behaviour, socializing, solitude, along with other factors such changes?

Obesity and Outdoor Activity

Since the major causes of death for individuals in developed nations have shifted from disaster (starvation, war) and disease (smallpox, malaria) to decay (cardiovascular disease, cancer), individual behaviours play an ever more bigger role both in longevity and excellence of life (Nesse and Williams 1996). One of the behaviours which have changed is exercise: Americans are less physically active today than previously. Although the reasons for obesity are multiple and never completely understood, insufficient exercise is one factor. The incidence of obesity in the usa has been increasing steadily in the last two decades.

Between 1991 and 2001, obesity rates increased 75 % among adults. Thirty-four percent of yankee adults are overweight, and 27 percent-45 million people-are obese. Only A quarter of adults in the usa report participating in recommended exercise levels, 29 percent report no regular exercise during free time, and only 27 percent of students engage in moderate-intensity exercise.

Only 50 % of young adults ages 12-21 regularly take part in vigorous exercise, and 25 % report no vigorous exercise at all (Hedley et al. 2004). Exercise today could be classified by cultural function: exercise essential for work, housework, and private care (travelling to the car, mopping the ground, taking a shower); exercise undertaken to enhance health (aerobics, weightlifting); and use undertaken for pleasure (gardening, hiking, playing tennis, dancing).

From the three, inherently pleasurable activities possess the greatest possibility to increase human movement in everyday life. Middle-aged and seniors are more physically active during leisure activity compared to what they are at their jobs or doing housework or personal care (Chow 2007).

4. Activities and Children’s Health

Children who spend some time outdoors are healthier, overall, than their indoor counterparts. Two health consequences of insufficient exercise are obesity and attention deficit disorder (ADHD); another childhood phenomenon which has broad implications for wellness continues to be called ?nature deficit disorder.

Obesity

The fitness of young kids has declined, and obesity has increased (Milnes 2008). Approximately 8 million youngsters are overweight. Obesity rates have doubled for kids (ages 6-11) and trebled for adolescents (ages 12-19) in only two decades. Today, 13 percent of kids and 14 % of adolescents are significantly overweight (RAND 2004; CDCP 2003; NANA 2003).

A lot more than 60 percent from the overweight children ages 5-10 have a minumum of one risk factor of coronary disease, such as elevated insulin, high cholesterol levels, or hypertension, and 25 % have several. Obesity can boost the risk of bone disease plus some cancers later and boost the risk of adult-onset (Type 2) diabetes.

Additionally, children who’re overweight prior to the age of 8 often become overweight adults. Obesity means a heightened chance of orthopaedic problems and poor sleeping habits, in addition to low self-esteem and peer relationship difficulties (Health link, Medical College of Wisconsin, January 14, 2009). Somebody that is 40 % overweight is two times as likely to die prematurely being an average weight person. Obesity can also be linked to gallbladder disease and gallstones, osteoarthritis, gout, and asthma (WEB MD, January 14, 2009). Parents are apparently conscious of those risks.

A current nationwide survey (Mott Foundation 2008) discovered that parents ranked obesity his or her primary concern regarding their children’s health, in front of drug abuse, smoking, bullying, and Online safety. Three studies using direct observation of preschool children are convinced that being outdoors may be the strongest correlate from the children’s physical activity (Sallis et al. 2000). Moreover, outdoor temperatures, both cold and hot, prompt your body to burn more calories compared to heated and air-conditioned environments. Most simply, time spent outdoors ‘s time not spent indoors, where youngsters are more likely to be sedentary.

Attention deficit disorder

ADHD is a neurobehavioral disorder seen as a pervasive inattention and/or hyperactivity-impulsivity, also it results in significant functional impairment (www.cdc.gov/ncbddd/ADHD/). The Centres for Disease Control estimates that 4.4 million youth ages 4-17 happen to be professionally identified as having ADHD, so that as of 2003, 2.5 million were receiving medication strategy to the disorder. Additionally, 7.8 percent of school-age children were reported by their parents to possess ADHD.

Scientific study has discovered that spending a little time outdoors can help to eliminate the the signs of ADHD. An immediate observation study figured even children whose symptoms hadn’t responded to medication showed an absolute behavioural improvement in outdoor settings (Kuo and Taylor 2004).

The symptoms were reduced most in green outdoor settings. Some children could cut their dosage of medication in two just by hanging out outside. They recommended that youngsters with ADHD spend after-school hours and weekend time outdoors: Overall, our findings indicate that contact with ordinary natural settings throughout common after-school and weekend activities might be widely good at reducing add symptoms in youngsters.

A green dose might be a lifesaver for that 10 percent of kids whose symptoms don’t react to medication … (1586)

Insufficient Connection with Nature

The word nature deficit disorder was coined to capture the overall consequences of not outdoors in natural surroundings. Based on Richard Louv (2005, 32), author of Last Child within the Woods-Saving Our Children from Nature-Deficit Disorder, nature deficit results in ?diminished utilisation of the senses, attention difficulties, and better rates of emotional and physical illnesses. Green space continues to be replaced by ?screen space in children’s spare time.

A Kaiser Family Foundation (2005) study discovered that the average American child spends 44 hours each week (more than Six hours a day) before an electronic screen. Each week, youth ages 5-18 spend 5 hours taking part in organized activities versus 15 hours watching television. Pergams and Zaradic (2008a, 388) refer to this as ?videophilia -the love of gaming, surfing the web, and watching movies and TV: The replacing vigorous outdoor activities by sedentary, indoor videophilia has far-reaching consequences for both mental and physical health, particularly in children.

Videophilia can be a cause of obesity, insufficient socialization, attention disorders and poor academic performance. The freewheeling outdoor play of history is declining sharply. Louv (2005, 31) writes, The cumulative impact of overdevelopment, multiplying park rules, well meaning (in most cases necessary) environmental regulations, building regulations, community covenants, and anxiety about litigation sends a chilling message to the children their free range play is unwelcome, that organized sports on manicured playing fields may be the only officially sanctioned type of outdoor recreation.

Moore (cited by Louv 2005) adds the next reasons for the decline of outdoor play: poorly designed outdoor spaces, domestic air-conditioning, apprehensive parents who keep their kids close to home, state-mandated curricula that don’t allow time for play outdoors, and overly structured lifestyles.

Addressing Children’s Wellness Issues

The forces arrayed against children’s free outdoor play are complex and won’t be easily overcome. The alterations needed might include adoption of Smart Growth principles in urban planning, a less litigious society, and much more provision for unstructured play outdoors, both in school and in the neighbourhood.

Although no absolute standards for children’s exercise have been set, Milnes (2008) stands out on the following: Daily structured exercise (active have fun with parents or day-care providers): toddlers, one-half hour; preschoolers, 1 hour. Daily unstructured exercise (riding tricycles, running, climbing): toddlers and preschoolers, a minumum of one hour, and preferably hrs. Sitting, being inactive: a maximum of an hour at any given time (except for sleeping). Research confirms what good sense would suggest: children and adolescents with quick access to recreational facilities and programs tend to be more active compared to those without (Sallis et al. 2000).

Adolescent girls’ exercise is related to the proximity of recreational facilities (Norman et al. in press). The greater often young adolescents use recreational facilities, the higher their total exercise; parks and also the neighbourhood play areas are most significant for boys, and commercial facilities and neighbourhood play areas are most significant for girls (Hoefer et al. 2002).

Preschool youngsters are more active the higher the number of nearby places where vigorous play is welcome and also the more time they spend in those places (Sallis et al. 1993). Use of playgrounds is a vital variable shaping children’s leisure choices. A nationwide Gallup (2003) survey discovered that fewer than half of yankee children possess a playground within easy reach of their homes.

Sixty-one percent from the surveyed parents say simple insufficient access to a playground is really a barrier for their children’s playing on one. 1 / 3 believes their community doesn’t have enough playgrounds, and two-thirds think that using a playground is really a deterrent to watching tv. School policy is yet another variable in outdoor exercise. One study discovered that few students used possibilities to be physically active during free time at school, and people changes in supervision, equipment, structured programs, along with other policies were required to involve more adolescents, especially girls (McKenzie et al. 2000).

A literature review by Wechsler et al. (2000) identifies four factors: recess periods, intramural sports and sports and physical eduction programs, exercise facilities, and psychosocial support for exercise. Schools can encourage exercise (and healthy eating) through school policies, administrative commitment, role modelling by school staff, interim management and also the use of cues and incentives. They conclude that enough is famous from theory, practice, and research to warrant implementation of school-based environmental ways of promote exercise.

Assessing the association of middle-school students’ exercise with school facilities, including area type, size, improvements (for example basketball courts), and also the presence of apparatus and supervision, Sallis et al. (2001) discovered that environmental characteristics explained 42 percent from the variance within the proportion of ladies who were physically active and 59 percent from the variance for boys. They figured schools rich in levels of supervision and improvements stimulated both kids to be more physically active. Although being outdoors is proven to be conducive to exercise (and to reduce stress-related disorders), little research addresses children’s outdoor playtime because it relates specifically to health.

One reason, based on Sallis (cited by Louv 2005, 33) is the fact that free play is free of charge: ?When children are running around or riding their bikes, they aren’t burning fossil fuel, not anyone’s captive audience, plus they aren’t making money for anybody. Follow the money. Finally, the easy act of spending more income for parks and recreation can be a critical element in the exercise levels of youth.

Research conducted recently, for instance, discovered that spending for parks and recreation inside a given state was positively correlated with two measures of girls’ overall exercise and with additional time spent in strength-building activity for girls and boys (Cawley et al. 2007, 514): ?… an additional $10 spent per capita on parks and recreation is assigned to a third of the day more each week of vigorous exercise. Research questions: Of the numerous variables-school policy, park policy, recreation programs, outdoor skills education, parental attitudes, community design, outdoor play resources-which tend to be more important in predicting children’s outdoor activity? What strategies increase such activity?

5. Measures of Activity and Participation

Time most Americans dedicate to outdoor recreation is pretty brief but may nonetheless confer benefits. Although we lack a generally accepted criterion of exercise (U.S. Department of Health insurance and Human Services 1996), criterion-reference standards for moderate and vigorous exercise have been proposed (Pate et al. 1995): Moderate: Half an hour per day for five or even more days each week. Vigorous: Twenty minutes per day for 3 or more days each week.

We can’t manage what we should don’t measure, however, and measuring exercise in activities and other settings is complex. Studies vary greatly in methodology, sampling techniques, and techniques of analysis. Further, many don’t measure duration or concentration of physical activity, or they are doing so only through self-report. A meta analysis of these studies could make up the basis for convening a specialist panel to determine a standardized protocol for future research.

Measures of Intensity

Currently, two basic approaches are utilized to measure the concentration of physical activity: indirect and direct (Mood et al. 2007). Indirect assessments ranges from single-response questions about self-report surveys to detailed diaries of exercise. Although such assessments are generally used, little is famous about their reliability and validity (LaPorte et al. 1985). Ainsworth et al. (1993) examined the test-retest (stability) toughness for 10 popular physical activity questionnaires for 1-month and 12-month periods and reported reliability estimates which range from a low of .12 to some high of .95; quite simply, the toughness for such instruments varies.

Direct monitoring approaches vary from simple job classifications to pedometers, accelerometers, and heart monitors. These assessments may include number of steps taken, quantity of calories expended, metabolic equivalents, and amount of activity. To estimate energy expenditure, the regularity, time, and concentration of physical activity should be measured. Ainsworth et al. (1993, 2000) created a compendium that classifies activities by energy expenditure levels.

This enables the comparison of various types of exercise along a typical metric of one’s expenditure. Several research has attempted to quantify exercise in public parks. Research based on a lot more than 3,000 observations of 18,000 activity groups in 13 Chicago parks discovered that 41 percent from the activity groups were involved in mobile activities, for example walking, biking, and jogging, and 14 % were involved in sports (Hutchison 1987).

Market research of Chicago’s Lincoln Park found 45 percent from the park’s users taking part in ?active-individual activities, such as walking and jogging, and 23 percent playing active team sports (Gobster 2002). Another study of Lincoln Park discovered that 43 percent of users ages 55 and older used bicycle and footpaths and considered exercise an essential benefit of park visits (Tinsley et al. 2002). From the users of Cleveland metro parks, 44 percent reported walking or hiking his or her primary activity. This ranked second behind ?relaxing, at 49 percent.

Research of Cleveland park users ages 55 and older discovered that more than 69 percent obtained moderate or high amounts of physical activity; a typical visit lasted about 2 hours, and users spent about 50 % their time walking (Ho et al. 2003). Walking for pleasure or being active is a common activity for seniors in parks, based on Scott (1997). An onsite survey of a big metropolitan park discovered that 55 percent of older adult users walked or hiked; alternative activities included walking dogs, having fun with children, bicycling, and swimming (Raymore and Scott 1998).

New Metrics

Some direct measures of park use and contribution to exercise are beginning for use. McKenzie and Cohen (2006) created a way to obtain direct info on park and recreation areas. Their System for Observing Play and Recreation in Communities (SOPARC) can be used to categorize park users’ exercise levels, sex, activity modes and kinds, and estimated age and ethnicity. Additionally, it provides info on park activity area characteristics, for example accessibility, usability, supervision, and organization.

Other metrics for park audits range from the BRAT-DO, which measures environmentally friendly characteristics of parks; environmentally friendly Assessment of Public Recreation Spaces (EAPRS) tool, which supplies a comprehensive direct observation assessment from the physical environments of parks and playgrounds; the road Environment Audit Tool (PEAT), some type of computer based instrument you can use by trained observers to evaluate physical characteristics of community trails and paths; and also the Core Measures of Trail Use, some questionnaire items about trail use and factors that could influence it in various populations.

Although these power tools are not yet extensively used, they hold commitment of providing more straight answers about exercise in activities areas and it is correlates. Park and recreation practitioners in many cases are unaware of such instruments and could lack personnel trained to rely on them. The need for learning the measurement of exercise within parks and outdoor areas along with other health-related measures is crucial and, to date, appears to remain problematic.

Trends in Participation

Probably the most important correlate between activities and health is really a relationship of mutual influence between a healthy body and participation in activities. That is, individuals who participate in activities are disproportionately in good condition, and people in good condition disproportionately participate in activities. This relation often happens for use of local park services (e.g., Payne et al. 2005). The majority of the national surveys that track participation in outdoor activities ask respondents when they have been recently involved in various forms of recreation.

However, they often do not measure duration and frequently assess frequency of participation crudely. Since period of time spent in a backyard recreation activity is really a critical variable for coping with obesity, reducing stress, and other health problems, the results from all of these surveys are of limited assist in assessing health outcomes. Also, activities may be defined in a way that the surveys neglect to capture important trends. For instance, 35 percent from the nation’s 96.4 million households grow vegetables, sometimes in community gardens on public land (Collins 2008), yet gardening isn’t included in activities surveys. Recreation surveys generally accept respondents’ estimates without validation, and also, since outdoor recreation is recognized as a desirable activity, respondents may overestimate their participation.

Additionally, most surveys ask people regarding their activities within the previous 7 days, two weeks, or perhaps a year. An all natural inability to recall behaviour over a long time, combined with selective forgetting (in line with the saliency of the experience) and telescoping (a propensity to remember newer events better), leads to inaccurate estimates . Having said that, studies do indicate certain trends. Because the late 1980s, the share of

Americans getting involved in fishing, hunting, camping, along with other nature-based activities has declined by a little more than 1 % a year, for any cumulative decrease in 18 to 25 % from peak levels (Pergams and Zaradic 2006, 2008a). The annual quantity of recreation visits to National Park Service sites declined from 281 million in 1986 to 273 million in 2006, almost 10 % (NPS 2007).

Visits to national forests dropped from 204.8 million in 2004 to 178.Six million in 2007, a 13 percent decline (Milstein 2008, citing U.S. Forest Service 2008). The premise that participation in activities is declining (Pergams and Zadaric 2008a) continues to be challenged; Jacobs and Manfredo (2008) contend that declines in a few activities happen to be generalized to any or all forms of activities, when in fact, alternative activities are becoming more popular. Hunting, for example, is declining, but no consumptive wildlife viewing is increasing.

The annual U.S. Forest Service survey (Cordell et al. 2008, finds a rise in participation between 2000 and 2007 in nature-based recreation: ?The development in viewing and photographing plants and natural scenery continues to be most rapid, at about 78 and 60 %, respectively.

Driving cars off-road occupies the amount three slot; it grew by 56 percent. Next come viewing, photographing, and identifying wildlife and birds. Four from the top five activities within the national forests, then, involve viewing, photographing, and otherwise observing nature. Research questions: When it comes to managing activities resources, should priority go on increasing participation or on improving opportunities if you are already regularly involved? What amounts of outdoor recreation opportunities are optimal for improving the health of citizens?

Utilization of Public Outdoor Spaces

To some remarkable extent, the regularity, duration, and kinds of use of municipal and county parks are unknown. ?Given deficiencies in recent federal support for park and recreation research, there’s been scant systematic research in the region of population-based exercise habits (Kruger et al. 2007, 1). A lot of the existing studies have been funded by local governments, designed to use various survey measures and research methods (Mowen et al. 2008).

Regardless of the incomparability of the data, it appears certain that local governments serve a lot more outdoor recreation participants than either federal or state agencies.

A five-city study of local parks discovered that 85 percent of adult users ages 50 and older had visited a nearby park in the earlier 12 months: 38 percent once per week or more, 22 percent 1 to 3 times monthly, and 25 % less than monthly; only 15 % had not attended a local park whatsoever.

In contrast, only 32 percent of Americans put together to have visited the nation’s parks, and just 28 percent the nation’s forests (Roper ASW 2004). Ethnic minorities constitute an essential user number of urban parks. Research of neighbourhood parks in low-income, minority urban communities discovered that more males than females used the parks, and males were two times as likely to be physically active (Cohen et al. 2007). Interviewees identified the neighbourhood park because the most common place they exercised. Proximity towards the park predicted both park use and use levels.

They conclude that public parks are critical helpful information on physical activity in minority communities. The nation’s Association of State Park Directors reports that state parks had 735 million tourists in 2001, and 91.2 percent were daytime users. State parks represent under 2 percent from the total activities estate but take into account more than 29 percent of visitors at federal and state outdoor recreation areas.

Research of six Pennsylvania state parks (Mowen et al. 2009b) discovered that a majority of respondents (63 percent) reported being moderately or vigorously active throughout their visits and were more mixed up in parks compared to their lives. Overnight visitors reported typically 90 minutes of moderate and 49 minutes of vigorous activity daily, and day users reported typically 68 minutes of moderate and 68 minutes of vigorous activity.

However, visits towards the survey parks along with other state parks were infrequent, with overnight visitors reporting typically only 6.4 visits each year and day users only 8.2 visits each year. There is some proof of a ?the more-the more phenomenon in leisure behaviour. That’s, the more likely are individuals to use one venue for exercise, the more they’re likely to use another. Thus, how you can assess infrequent but active utilization of public activities areas remains problematic-especially since funding for municipal assuring recreation and park services has already been suffering and could decline in the present economic recession (Dolesh 2008). Research questions:

Can the health advantages associated with utilization of public recreation and park service’s be superior and more systematically documented? Can a much better understanding of the various benefits supplied by nearby local parks, state parks, along with other open spaces be gained through additional surveys and research?

6. Factors affecting Participation

An increasing research literature props up proposition that individuals who live in activity friendly environments may be more physically active throughout their leisure time (Sallis et al. 2000; Humpel et al. 2002; Killingsworth 2003; Owen et al. 2004). Active Living Research (www.activelivingresearch.org) summarizes the key findings of these research: the proximity, safety, supply, and style of recreational spaces are essential factors in predicting physical outdoor activity. Additional factors affecting participation are accessibility to leisure time and also the nature from the community. The next subsections consider these variables.

Free time

Time use research has shown that Americans come with an average of 35 to 40 hours of spare time per Week. Nearly all this time, however, is available in small chunks during weekdays, instead of in big blocks on weekends. TV viewing occupies about half of free time (Table 1). Add the 27 hours monthly of Internet use (for work and leisure) which is apparent that looking at screens is really a major utilization of Americans’ time (Nielsen and Hansen 2007). By comparison, exercise, sports, and activities account for no more than 8.5 hours monthly. Outdoor recreation, then, is pretty rare. Indeed, if car travel is recognized as an ?indoor activity, Americans spend 95 % of their lives indoors .

Leisure activity Average minutes daily Watching TV 156 (2.Six hours) Socializing, communicating 46 Other leisure activities 29 Reading 22 Relaxing, thinking 19 Doing offers, using computer for leisure 19 Sports, exercise, recreation 17 Total 308 (5.1 hours) Most people do not use their paid leave for fear they may be laid off or demoted. Unlike 127 other countries, america has no minimum paid-leave law.

Legally, Australians have a month off, Europeans 4 or 5 weeks, japan two weeks. The paucity of vacations and extended personal the years have health consequences for Americans, resulting in fatigue, accidents, and injuries. Job stress and burnout cost the U.S. economy a lot more than $300 billion annually.

A recent survey determined that two-thirds of Americans thought vacations ought to be mandated by federal law (www.timeday.org). During vacation, people take more time outdoors, walk more, watching TV less . More frequent annual vacations for middle-aged men at high-risk for chronic cardiovascular disease are of a reduced chance of all-cause mortality and specifically mortality related to chronic cardiovascular disease (Gump and Matthews 2000).

Vacations can alleviate perceived job stress and burnout (Westman and Etzion 2001). In a nutshell, vacationing might be good for one’s health (Gump and Matthews 2000). Yet comparatively little is famous about health insurance and the durations and kinds of vacations, or concerning the relation between your amount and sequencing of spare time during the weekly cycle and health-related variables, like the amount and kinds of activities participation. Research question: So how exactly does free time-its duration, its frequency, its occurrence during the period of a week or year-affect the probability of engaging in outdoor outdoor recreation?

Community Attributes

Increases in obesity happen to be blamed on the single-use zoning that helped create today’s sprawling suburbs since it is said to have removed exercise from everyday life: when people can’t walk to operate or the supermarket, they get less exercise. People residing in urban sprawl do generally have higher weight indices. Conversely, individuals with higher weight indexes are disproportionately prone to move to and prefer regions of urban sprawl (Planting and Bernell 2007).

Overview of 17 studies discovered that walking like a mode of transportation was highly relevant to to residing in high-density residential neighbourhoods and short distances to destinations (Saelena and Karr in press). Although such findings aren’t unequivocal-Eida et al. (2008) find no evidence that urban sprawl causes obesity-Active Living Research (2008) reports that six research has shown walking is positively associated with population density and just two don’t; eight research has shown that walking is positively associated with mixed land use and just three don’t; and seven research has shown that distance to destination relates to walking and just two don’t.

Active Living Research (2008) concludes that individuals living in traditional communities-defined as individuals with walking and bike trails, quick access to the bus, and a town centre where homes are clustered around shops and office buildings-are more physically active and fewer likely to be overweight. The business also notes that traditionally designed neighbourhoods are endorsed through the Surgeon General and also the Institute of drugs. Interest in residing in Smart Growth communities might be increasing. National survey data reveal that public support for traditionally designed communities increased from 44 percent in 2003 to almost 60 percent in 2005 (Handy et al. 2008). Several strategies recommended by advocates of Smart Growth connect with outdoor recreation and use of green spaces and parks: creating walk able neighbourhoods; preserving open space, farmland, natural splendor, and critical environmental areas; and providing a number of transportation choices.

Proximity to Outdoor Spaces

Proximity to activities opportunities is really a critical variable for explaining participation rates. Starting in the 1960s, studies showed an inverse relationship between recreation participation and distance from a place of residence and recreation opportunity (e.g., Cicchetti et al. 1969).

Creating and improving recreational spaces can spark a 25 % increase in people who exercise a minimum of three times each week (CDC 2002). The closer people live to some bikeway, the more likely they’re to use it (Troped et al. 2001). Kaczynski and Henderson (2007) summarize evidence concerning the role of park proximity in exercise.

Eight of 13 articles reported positive associations between park proximity and exercise. For example, a national survey of U.S. adults discovered that perceived use of parks and recreational facilities was significantly associated with self-reported physical activity (Brownson et al. 2001).

Another study discovered that having a minumum of one recreation or open space setting within one kilometre of youths’ homes was consistently associated with walking at least one time in a two-day period and walking higher than a half-mile each day (Frank et al. 2005). Across six cities, adolescent girls who were built with a higher quantity of parks just one mile at home were more prone to achieve higher amounts of physical activity (measured using accelerometers) than girls who had fewer parks near their houses (Cohen et al. 2006). A five-city study discovered that having a park within easy reach of one’s home was the best predictor that the older person would make use of a park.

Adults in Nyc, Baltimore, and Forsyth County, New york, were 28 percent more prone to participate in recreation activities if there have been parks and recreation facilities within five miles of home. Having facilities within one mile was related to significantly higher amounts of physical activity among Hispanics and African Americans (Diez- Roux et al. 2007).

Safety of Parks

A connection between actual safety (instead of fear of crime) and outdoor exercise has not been definitively established. Inside a review of the literature, Powell et al. (2003) are convinced that four studies found no significant relation between safety and walking in one’s neighbourhood, but three other studies found this type of relation.

Among the latter discovered that recommended activity levels were met by 43 percent of people that had safe places just to walk within Ten minutes of home, versus only 27 percent of these without safe places (Powell et al. 2003). An onsite survey inside a large metropolitan park discovered that among seniors, female park visitors had much more fear of crime than did males (Raymore and Scott 1998).

A sizable sample study of AARP members ages 60 and older examined relations between crime and native park visitation in five New england cities. Anxiety about crime was discovered to be an essential variable, and former crime victims (9 % of all those surveyed) were particularly fearful. Respondents reported that going to and in the park was more worrisome than finding yourself in the park itself.

An investigation technique that could elucidate relations between crime and park use involves using geographic information systems. GIS can demonstrate spatial relations between disparate data, for example crime statistics, census information, and land use. Pendleton and Thompson (2000) claim that criminal occupation and activity within parks may consume a recognized pattern, and the like patterns could be revealed and represented using GIS (Suau and Confer 2005).

Way to obtain Outdoor Spaces

The amount and section of parks and playgrounds inside a community are positively associated with physical activity levels. Numerous studies document this connection. For instance, a study of some 500 seniors from 56 neighbourhoods in Portland, Oregon, discovered that both the quantity of recreation facilities and also the area of green or open space were significantly associated with high amounts of walking (Li et al. 2005).

In West Virginia, total county acres managed by public agencies, total county acres dedicated to water-based recreation, and also the number of recreation facilities were positively associated with countywide physical activity (Rosenberger et al. 2005). Even though number and section of parks inside a community may have a positive affect on physical activity, large parks aren’t any more likely to be related to higher activity levels than smaller parks. For instance, a study of 4 neighbourhoods in Ontario found no relationship between your size of parks as well as their use for exercise (Kaczynski et al. 2008).

The possible lack of parks in lots of communities is exacerbated through the shrinkage of schoolyards as schools install portable classrooms so that as land becomes increasingly scarce and expensive. Schools’ sports and physical eduction programs are now being cut, and several children lack use of safe recreation facilities. Kids of colour often don’t have access to parks and schoolyards within their communities, and several cannot travel-whether by car or transit-to neighbourhoods which have parks (Giles-Corti and Donovan 2003; Gobster 2001; Garcia 2002).

Park and Playground Design and Features

Certain options that come with parks promote exercise. A literature review by Mowen et al. (2008) cites an observational study that assessed visitors’ activities and expenditures in 28 parks in Tampa and Chicago. Parks with soccer fields, tennis and racquetball courts, basketball courts, volleyball courts, and playgrounds were related to moderate to vigorous amounts of physical activity and overall higher amounts of park-based energy expenditures (Floyd et al. 2008).

In another study, researchers examined 28 features-bike paths, ball fields, and thus forth-in 33 parks and located that parks with increased features were more prone to be used for exercise than parks with fewer features. Parks with paved trails, for instance, were 26 times more prone to be used for exercise than parks without paved trails (Kaczynski et al. 2008).

Research of four park types (city park, neighbourhood park, waterfront park, ?extreme park) discovered that levels of moderate or vigorous activity were highest within the areas containing courts, playgrounds, sports fields, and paths, whereas sedentary activity was seen in open green spaces as well as in picnic and pavilion areas (Shores and West 2008). The characteristics and biophysical characteristics that encourage park use can vary.

Natural areas are related to high use rates in certain cities, but anxiety about crime may discourage utilization of natural areas in other people. Schroeder and Anderson (1984) discovered that degree of naturalness and woody vegetation increased the perceived scenic quality of park environments. However, naturalness and vegetation correlated negatively with perceived safety, suggesting that open lines of sight enhance perceptions of safety (Gobster and Westphal 2003).

Some investigation indicates that African Americans prefer environments which are open, well-groomed, and also have more built amenities like ball fields and pavilions, instead of wild land recreation areas (Johnson and Bowker 1998; Payne et al. 2001). Park managers and groundskeepers can transform environmental factors in activities areas to advertise park visitation and exercise. Problems with proximity could be mitigated by locating facilities and program areas across the perimeters so that the attractions are visible and simply accessible (Gobster 2001; Giles-Corti and Donovan 2003).

Social Establishing Parks

The social setting-the composition of recreation and park users as well as their interactions- is another variable affecting participation in outdoor activity. Crowding in outdoor settings involves not just physical limits but additionally norms, which can be influenced by the private characteristics of visitors, the options of those they encounter, and also the features of the park itself. Crowding is usually perceived as an adverse that takes away from the quality of a user’s experience (Manning 1999), particularly in backcountry areas, but is usually associated with positive visitor experiences in urban parks (Westover and Collins 1987), mostly since it is associated with safety.

Many scientific study has observed that crowding norms will vary for different user groups. Perceptions of crowding can vary depending upon experience, motivations, and expectations (Ditton et al. 1991). Determining what’s undesirable must start by determining the norms for crowding in the specific area or facility (Manning et al. 2001). Several studies have examined the result of intra-activity conflict on urban park use and located that conflict doesn’t seem to detract from park experiences (Schneider 2000). Again, however, perceptions can vary by activity group.

For instance, Moore et al. (1998) discovered that greater proportions of walkers and runners reported that skaters and bikers detracted using their enjoyment than the other way around. Qualitative studies indicate that criminal activity, like the sale and employ of illegal drugs, deters park use by adults and children (Outley and Floyd 2002). Utilization of urban parks may also be affected by needing to traverse ?gang territory (West 1993).

Park Management and Policies

Park administrative activities can promote or discourage utilization of parks. Some social interactions, such as the issues described above, could be managed by regulating certain uses, equipment (e.g., motorized vs. non-motorized), and activities, in addition to by temporal spacing of activity types. Because the mid-1990s, user fees happen to be implemented or increased at local, state, and federal recreation areas. Fishing, hunting, and snowmobiling, for instance, often require licenses, permits, or user fees; the revenue collected may support other kinds of activities overseen through the regulating agency. Findings around the effect of recreation pricing are mixed.

Research of six U.S. Army Corps of Engineers day-use areas discovered that 40 percent of respondents would reduce their visits if fees were implemented (Reiling et al. 1996). However, studies from state parks indicate that pricing has little if any effect on recreation use levels (Becker et al. 1985). However, Scott and Munson (1994) noted that among low-income households, reduced costs, along with better the bus, childcare, and safety, would cause residents to make use of parks more regularly.

This finding is congruent having a national study that discovered that 50 percent of low-income respondents cited cost or affordability as barriers to exercise (Moore 1996). Some visitors, however, may avoid free recreation and park areas because uncontrolled access is assigned to higher crime rates (Fletcher 1983). Research questions: Leaving aside people’s attitudes toward fees, do user fees actually depress park visitation and therefore have health consequences? Can fee structures encourage participation in beneficial activities?

If activities is to bring about the health of Americans, recreation policy must be formulated poor demographic and change in lifestyle. The post-World War II boom in activities participation would be a product of countless forces, including a fiscal surge, an upswing of the middle-class, jobs that included paid vacations like a benefit, and also the huge cohort of kids born from 1946 to 1964. Activities became area of the white, middleclass lifestyle. Recreation managers worked to help keep supply adequate to demand, and also the federal government incorporated recreation into governance, providing funding, research, and planning expertise to states and municipalities. Today, American culture is faster-paced and impatient.

Activities activities which have broad appeal are the ones done in each day without specialized gear (Outdoor Industry Foundation 2006). Some marketers characterize the expectations of today’s activities participants as ?made by dinner. The economy is different, too. Historically, during economic downturns, individuals have used public recreation and park services more, not less: economic woes often change leisure behaviour with techniques that favour activities (e.g., Knapp and Hartco 1979).

White, middle-class families-the traditional base for outdoor recreation-have declined like a proportion from the population, and participation in activities occurs at ‘abnormal’ amounts across the faster-growing demographic segments. Dwyer (1994, 3) reports ?significant differences across racial and ethnic groups, with significantly lower participation for African- Americans for activities happening in a wild land environment.

Lower rates of participation by some minority groups are attributed both to limited economic resources and also to differences in norms, value systems, and socialization patterns (Floyd and Gramann 1993). Newer studies find some rise in participation by ethnic minorities, disproportionately young males (Outdoor Industry Foundation 2006). The historical gaps in ethnic minorities’ participation might be exacerbated by demographic change. Think about the following U.S. Census Bureau predictions for 2050, once the total U.S. human population is expected to have grown to 439 million: Ethnic minorities increases from one-third from the population right now to more than half by 2050; non-Hispanic, single-race whites will take into account 46 percent.

Nearly one out of three U.S. residents is going to be Hispanic. The black human population is projected to improve from 14 % of the total to fifteen percent. The Asian human population is projected to climb from 5.1 % to 9.2 percent. The populace of minority children is anticipated to rise from 44 percent to 62 percent. Ethnic minorities are not as likely to participate in activities or value government involvement within the provision of these services (e.g., Ho et al. 2005; Sasidharan et al. 2005).

Another essential demographic issue requires the role of gender and just how males and females take part in outdoor activities. State game and fish commissions cater more towards the interests of primarily male hunters and anglers, for instance, than to birdwatchers or nature photographers of either sex, although the latter activities are growing dramatically (Cordell et al. 2008).

8. Policy Implications

Activities has generally been an auxiliary utilization of government-managed lands, and federal recreational land often lies far distant from the potential users. Funding for local recreation and park service’s varies widely over the states (Crompton and Kaczynski 2003). Because of the health contribution of outdoor recreation-and the associated health financial savings that could accrue from the general rise in Americans’ outdoor physical activity-it might be appropriate to rethink where the nation provides recreational services.

Managing Activities for Healthy Outcomes

The organizations that manage activities opportunities should plan, manage, lead, and evaluate for health advantages. A growing number of public park and recreation agencies in a number of countries are actually planning and managing for beneficial outcomes. Detailed reviews of a few of these applications of benefits-based management, now called outcomes-focused management (OFM), come in Driver (2009).

Exactly what does a focus on ?healthy benefits mean? Practitioners must shift from merely providing recreation possibilities to promoting activities that deliver health advantages. One way to manage for health advantages involves partnerships among schools, recreation and park agencies, and health organizations. Such partnerships could be effective in raising health awareness (Spangler and Caldwell 2007).

A national survey finds that almost nine from ten local recreation and park agencies happen to be participating in a minumum of one such partnership (Mowen et al. 2009a). Schools and public health agencies would be the most common partners, and exercise promotion, obesity prevention, and general wellness would be the primary aims. Respondents whose health partnership centered on promoting exercise took primarily programmatic and environmental approaches-that is, holding special attractions like five-K walks, establishing programs like water exercise for arthritic adults, and creating park features like bicycle trails.

Developing a metropolitan Strategy

Incorporating activities into city dwellers’ daily routines ought to be a priority strategy. Utilization of local parks and recreation services is a lot more frequent than visits to nature and may therefore convey more health benefits. Once we have seen, proximity to local parks, playgrounds, along with other outdoor recreation resources is really a critical variable for taking part in outdoor activities. The activities ?supply is an important variable in determining use: the supply and number of features and facilities are critical.

Providing recreation facilities for urban and suburban children is particularly important. Children need places where they may be outdoors and physically participating in a regular basis, in their own individual neighbourhoods; such places include both public parks and commercial facilities. Because children participate in such a number of activities and since their recreational needs vary widely by age, providing various sorts of facilities is really a promising policy objective (Sallis and Glanz 2006). School policy, leadership, and facilities are essential determinants of the exercise levels of students. Outdoor skills and appreciation should be taught and also the existing activities preferences of minority children better understood and deliver to.

Policy Options and Questions

The findings of the literature review indicate potential new directions for activities policy, in addition to new inquiries to be explored. The U.S. Fair Labour Standards Act ought to be amended to want paid vacations for workers. Planning outdoor recreation in cities should involve not just schools and recreation and park departments, but additionally public health, transportation, public utilities, hospitals, and organizations such as the Nature Conservancy and Master Gardeners.

Governments could purchase outdoor recreation by developing trail systems in cities and rehabilitating potential recreation sites, including brown fields. Crime reduction efforts that concentrate on parks and surrounding areas would help people feel safe in the park and travelling to it. Land-use planners who adopt the Smart Growth principles of mixed-use zoning and walk able neighbourhoods may encourage more exercise.

Training in the strategy of measuring exercise and other health-related measures is required. Park and recreation practitioners in many cases are unaware of new, reliable metrics or may lack personnel trained to rely on them.

More funding for scientific studies are needed. Measurement is a barrier to promoting public health programs within an outdoor recreation setting, and funding for research largely determines the extent that sophisticated measures may be used. A meta analysis of studies of local park and playground use could make up the basis for convening a specialist panel to determine a standardized research protocol, to ensure that future research on exercise can collect comparable data for analysis.

Fees for many activities might be used to subsidize alternative activities that deliver greater health advantages, making them more appealing. The Centre for Law within the Public Interest has advocated similar measures, including open space for recreation (parks, schoolyards, beaches, national forests and parks), joint utilization of parks and schools to create optimal utilization of land and public resources, daily sports and physical eduction for all students, educational programs in schools and parks to instil lifelong values of health and fitness and good nutrition, public education campaigns to articulate the requirement for active recreation ought to be human health, and diversifying use of and support for wilderness areas.

Several policy questions also leave this literature review. Should some time and resources be spent to encourage participation in outdoor activities that demonstrate declines, for example fishing, hunting, and tent camping, or should we invest more resources within the activities which are gaining in popularity, for example nature photography?

Should emphasis be on helping the frequency, duration, and concentration of participation by those people who are already prone to participate? Or should emphasis be on involving individuals with low participation rates, for example African Americans, Hispanics, the indegent, and females? Just how can state-level provision of activities more deliberately range from the interests of ladies and ethnic minorities to increase contributions for their health? Just how can these groups come in contact with attractive activities opportunities? If the United States attempt massive projects to build up and improve community parks and recreation services, such as the programs from the Great Depression?

Funding is definitely a question, but particularly in an economic downturn. Historically, funding for parks originates from departments worried about land acquisition and management or with urban affairs; today, efforts to improve outdoor recreation activities have to originate in public places health agencies, using the cooperation of federal land management agencies assuring park, community affairs, and related agencies. Incorporating such efforts in to the national diary for public health could make the required funding both palatable to Congress and good at meeting the aim.
