There are many reasons why individuals might not meet the Physical Activity Guidelines, but one major factor is the physical environment that surrounds them. When people don't have the option to make the healthy choice regarding their participation in physical activities, there is no possible way they can do it.

Over the past several decades, our society has engineered physical activity out of our lifestyles. For example, 13% of children five to fourteen years old usually walked or biked to school in 2009, compared with 48% of students in 1969. For a long time, neighborhoods were being built without regard for pedestrians, putting the needs of the driver first. Safe biking lanes, walking paths that connected places where people wanted to go, and a variety of safe outdoor play spaces were all but engineered out of most built environments. Schools were being put in a position where they had to eliminate physical education, whether for budget reasons or to meet academic goals. Offices were built without bike racks, employee changing areas, or easy to use staircases, further enhancing less physical activity instead of more.

Fortunately, things are starting to change. A healthier communities movement is building across the nation. The Y, along with other national organizations, is leading the way. Since 2004, with support from the Centers for Disease Control and Prevention and other corporate and foundation donors, the Y has engaged leaders in 200 communities in working together to implement strategies that provide opportunities for physical activity.

YMCAs engaged in our Healthier Communities Initiative (pioneering Healthier Communities, Statewide Pioneering Healthier Communities and ACHIEVE) are helping families by giving parents peace of mind when they let their kids walk to school. The initiative is focused on creating safer routes, making streets safe for all users whether they are on foot or on wheels. The organizations strive to keep a generation of kids healthier by working with schools to increase physical education and physical activity during the school day, and making recess periods more active. The initiative also encourages employers to build environments that support activity among their employees. These examples are just the beginning.

How healthy is your community? What are examples of your community's efforts to change the built environment so more people engage in physical activity to meet the PA guidelines? How are you helping people see that their own built environment supports or inhibits meeting these guidelines? What barriers are there, and how can you work with other leaders in your community to collaboratively remove those barriers?

May is National Physical Activity Month and what better way to celebrate being active than to walk your dog. He'll appreciate it just as much as you will. Obviously strenuous exercise, such as running and other forms of cardiovascular exercise, and sports are are excellent ways to achieve health and meet the activity standards established by the Department of Health and Human Services. But finding simple ways for children and adults to integrate activity into their normal activities might be the best way to get people moving.

A new study published in the March issue of the Journal of Physical Activity and Health suggests a potentially great idea for all Americans to become more active. The study, presented by Matthew J. Reeves et al., looks at whether owning a dog and walking the dog are associated with increased physical activity. They gathered data from the 2005 Michigan Behavioral Risk Factor Survey to try to determine if a relationship existed between owning a dog and physical activity.

The authors found that people who own a dog are more active overall and walk more. Dog owners who take their dogs for walks on average walk about one hour more per week than the one-third of dog owners who don't walk their dogs. Interestingly they also found that younger Americans and the elderly walked their dogs the most and that people with large dogs (weighing over 45 pounds) walked longer than owners of smaller dogs. Finally the study seems to suggest that the benefits of owning a dog, as it pertains to physical activity, may actually be more than just the actual walking, as dog owners seem to be more physically active than non-dog owners in general.

When I heard about this study, I was not terribly surprised. I always like to find easy ideas to stimulate physical activity. For instance, I think it is helpful to take the stairs instead of an elevator when possible. Also, parking at the end of the parking lot away from stores and businesses forces people to walk a little bit more with their normal activities. Owning a dog and walking it are more examples of easy changes to implement.

What this study does not address, but most dog owners will tell you, is that the benefits of having a dog are not just seen with physical activity. Most of my friends who have a dog point out the happiness that comes when their dogs greet them when they get home from work or school. They also love taking their dogs to the park and the beach. So to everyone out there who owns a dog - get outside and walk with your four-legged friend. It just might improve your health too.

What are some other ways to get more active with your four-legged friend?

Public park and recreation agencies and school districts in many areas have utilized Joint Use Agreements (JUA) for years. The National Policy & Legal Analysis Network to Prevent Childhood Obesity (NPLAN) "defines a JUA as a formal agreement between two separate government entities - stating terms and conditions for shared use of public property or facilities." Pooling of resources allows for more effective use of government dollars, which in today's economy takes on even greater meaning as well as a heightened sense of urgency. Groups advocating for physical activity have recently begun encouraging more towns, cities and counties to consider such agreements as a way to increase the number of physical activity opportunities for their residents.

Consider the following... School playgrounds are open to the community on weekends in San Francisco as a result of a joint use agreement between the school district and the city. The City of Seattle took things a bit further... they designed and implemented a program that centralized scheduling of both school and recreation facilities, which streamlined the reservation policy and increased access. In several communities, schools and cities have combined their resources to build new recreation facilities that serve the needs of both the schools and the community (NPLAN).

The National Physical Activity Plan includes JUAs as important strategies in both the Education sector and the Parks, Fitness Recreation and Sport (PFRS) sector. The Make the Move Report - 2010-2011 National Implementation of the U.S. Physical Activity Plan lists increasing the number of JUAs by 10% over the next 5 years as a priority for the PRFS sector. The President's Council on Fitness, Sports and Nutrition is co-leading this strategy with the National Recreation and Park Association.

I encourage advocates to look beyond government though for JUAs and to consider the possibility of public-private agreements. The Wheaton Park District used an innovative approach to increase their number of (much in demand) soccer fields. A large corporate campus sat at the edge of park district and had plenty of flat (this was Illinois!), green space that was there purely for its aesthetic value. The two organizations signed an agreement that stated the park district would mow the grass in return for its use as soccer fields evenings and weekends. I dare say there are many possibilities like this across the country.

Perhaps there is a private health club located near a school. Use of the club may be sparse during the day... what a great opportunity for a PE class! Maybe there's a camp nearby used only in the summer... strike a deal for use of its athletic facilities. Many places of worship even have recreational facilities. The possibilities are endless to increase spaces and places for people of all ages to engage in physical activity - if you just think the outside the box a bit!

What kinds of unique joint use agreements can you think of? Are there facilities in your own community that you could see working with to increase the opportunities for physical activity?
