This study in Minneapolis, Minnesota, finds that commuting rates by bicycle increased substantially between 2000 and 2010 once 10 miles of paved paths separated from roadways were created. Using careful statistical methods, they show that neighborhoods closest to the new paths and with the most commuting routes crossing the paths had the greatest increases in bike commuting rates.

In northwest Arkansas, a substantial investment in paved and unpaved trails has contributed substantially to the region’s well-being (measured in improved health) and economic performance (measured in visitor spending and employee retention). Evidenced by residents’ interest in living close to trails and willingness to pay more for homes near trails, cycling is an essential part of life in this region.

This large study of U.K. residents finds that those who walk or bike to work have significantly lower incidence of and mortality from cancer and cardiovascular disease. Those who incorporate cycling into their commute had the greatest reduction in risk of disease incidence and mortality.

In Miami-Dade County, Florida, an afterschool, park-based program is effective in improving physical fitness among a sample of 52 children with intellectual and developmental disabilities. Afterschool programs may be an effective strategy to increase physical activity among disabled children, who tend to be less physically active than their non-disabled peers.

A formal walking program for children diagnosed with attention deficit hyperactivity disorder (ADHD) finds that low-intensity walks in an urban park are associated with significantly greater improvement in cognitive function than similar walks in residential or downtown settings. The improvements measured are on par with improvements associated with the most typical medications prescribed for ADHD, and cognitive performance for participants after walking is comparable to the average performance of children who have not been diagnosed with ADHD.

In Miami-Dade County, Florida, researchers evaluated the structure of a pilot project connecting children, families, and their pediatricians to a park-based afterschool program. This study describes important factors encouraging ongoing support from participating families and pediatricians, as well as ways to measure the effectiveness of prescription parks programs.

A daily afterschool program in Miami-Dade County, Florida observes significant decreases in body mass index (BMI) and blood pressure between the beginning and end of the school year. Findings from this research suggest consistent, long-term afterschool programs can effectively reduce childhood obesity and cardiovascular disease risk.

In this large-scale study of participants in a formal walking program in the U.K., researchers find that participants in nature-based group walks are less likely to report experiencing depression, perceived stress, and negative affect, and report greater overall mental well-being. By comparing a large sample of participants and non-participants over time, the authors overcome some inherent challenges in measuring the effectiveness of these types of programs.

In Taos, New Mexico, Hispanic residents and low-income residents are less likely to have used trails during the previous year, but those who have used trails during the previous year use them just as often as other (non-Hispanic) residents. Among low-income residents, those with a park or trail within a 10-minute walk of their house were 50 percent more likely to have used trails during the previous year.

By following a large sample of children over time, this study demonstrates that children who participate in recreation programs, or who live a walkable distance from parks, are much less likely to be obese or overweight. These benefits can be achieved through formal parks and programs, but also through accessible green space or other small, informal places that encourage informal play.

Research has established that low-income people tend to have higher mortality rates than high-income residents. This study across all of England demonstrates that this gap in mortality rate is about half the size in areas with the most green space compared to areas with the least green space.

At a sample of recreation centers in southern California, researchers find that several measures of facility condition and amenities are better in high-income neighborhoods relative to low-income neighborhoods. The likelihood that a child uses the recreation center increases 23 percent for each $10,000 increase in neighborhood income, but the authors do not find a relationship between the quality of the facility and participation rates.

A large study of 50 urban parks in Southern California measures park use by nearby residents and other users across high-, medium-, and low-poverty areas, finding that parks are used less in high-poverty areas. Those who do use parks in high-poverty areas, however, on average use the parks more per week, are more likely to see familiar people in the parks, and use the parks more when there are more staff present.

In rural Nova Scotia, a proposed trail is expected to increase substantially the amount of physical activity of local residents, with over half of respondents predicting increased physical activity due to the trail. For every dollar spent constructing the trail, it is expected to generate at least $2 in avoided health care costs.

A media campaign to promote a trails information site in Las Vegas, Nevada appears to have significantly increased trail use across most trails studied. The size of the gain in trail use appears to be independent of trail lighting, landscaping, and trail length.

In Durham, North Carolina, a bicycle-pedestrian bridge was built to connect two previously separate segments of a regional trail, leading to a 133 percent increase in trail use after its construction. This new connection allows the researchers to demonstrate a substantial increase in physical activity attributable to the bridge, with significant public health benefits for trail users.

Combining data from 10 U.K. studies, researchers demonstrated statistically significant improvements in self-esteem and mood after participants exercised outside in a natural setting. Although all cohorts and types of settings experienced improvements, the greatest gains are visible after short duration, light exercise, and among the mentally ill.

Trails in Lincoln, Nebraska have the potential to generate large benefits for trail users in terms of avoided medical costs. These benefits may significantly outweigh the per capita cost of trail construction and maintenance. However, due to simplifying assumptions made regarding both benefits and costs, the cost-benefit ratios are unreliable.

This study found that bicycling in Michigan generates $224 million annually through retail spending, manufacturing, and event and tourism spending. Additionally, the improved health of those who commute to work by bicycle in the state is associated with up to $256 million in avoided annual health care costs.

This study found that older women in Pittsburgh, Pennsylvania walk more overall if they live within walking distance of a trail, and those who use trails use them at least twice per week. Proximity to trails had the strongest relationship with increased walking among 14 neighborhood destinations, including parks, retail establishments, and public services.

This study found that in Morgantown, West Virginia, one-quarter of trail users had not been active before the trail was built, and who report large increases in physical activity since they began using the trail. For most of these newly-active residents, the trail was the only place where they exercised and they report the trail’s safety, paved and flat terrain, and convenience as the most important considerations in deciding to use the trail.

This study found that walking trails in rural, southeastern Missouri communities are associated with the greatest increase in exercise for those most at risk of inactivity, particularly those who were not already regular walkers, have a high school education or less, or who earn less than $15,000 per year. Trails that were at least a half mile long, paved, or located in the smallest towns were associated with the largest increases in exercise.

This study found that 13 million days of cycling occur in Wisconsin each year, roughly half of which are taken by non-residents who contribute $309 million to the state’s economy. The health benefits associated with increased physical activity for residents could reduce annual healthcare costs in Milwaukee and Madison alone by up to $320 million, and less pollution due to fewer car trips is associated with as much as $89 million in benefits.

This study found that a community rail-trail in West Virginia encourages new physical activity among inactive residents and greater physical activity for those who were already active, and that for many community members trail use is their only form of exercise. Trail cost per newly active resident is on the lower end of health interventions aimed at encouraging sedentary individuals to become active, and is likely to reach more people that other common interventions.

This study found that three-quarters of trail users in Lincoln, Nebraska report being more physically active since they began using trails, most of whom are active for general health. The cost per user who is more active since they began using the trails is $98, less than other programs aimed at increasing physical activity.

This study found that extending a rail-trail from the outskirts of Fall River, Massachusetts into the city center is likely to generate a range of benefits for the community, including increased physical activity, fewer pedestrian and cyclist crashes with motor vehicles, increased business activity and improved working environment, and less air pollution. This study is an example of a small city’s Health Impact Assessment, a single document that can be used by trail planners and advocates to justify the investment of public funds.

This study found that residents who live closer to rail-trails in Arlington, Massachusetts got an hour more exercise for transportation purposes each week. Proximity to the trails had no effect on the amount of exercise for recreation, suggesting the neighborhood trails in this community are mainly used for transportation purposes.

This study found that a marketing campaign to promote the opening of a new rail trail in Sydney, Australia did little to increase awareness of the trail or increase trail use in the general population. However, it was effective in raising awareness of those who lived closest to the trail.

This study found that constructing a cycling-specific route separate from vehicle traffic has the potential to make cycling much safer for commuters in Dublin, Ireland, reducing mortality risk by 18 percent. In monetary terms, the benefits of reduced risk outweigh construction costs by at least two-fold.

This study found that people who used a new rail trail in Durham, North Carolina reported exercising more during the month after it opened, although it did not appear that their minutes spent exercising per week was actually any higher than before the trail opened. Potential effects of new trails on physical activity may take longer to manifest themselves in residents’ habits, and the effects likely depend on how many trails are already nearby.

This study found that in southeastern Missouri, public health interventions to increase residents’ trail use, such as newsletters and fun walks, had no statistically-observable effect on residents’ walking habits or physical activity. A third of those who use the trail report increased overall physical activity levels since they began using the trail, suggesting while that trails can increase community physical activity, a primary challenge is getting residents to begin using them.
