As a nation, we know that our own choices and behaviors - including physical inactivity - have contributed to rising rates of chronic disease and obesity. It seems easy enough to encourage individuals and families to engage in more physical activity. But the reality is that in many communities across the nation, making healthy choices such as getting active is not only difficult; sometimes it's not even option.

"It's not that hard," we might say. "Just go out and take a walk around your neighborhood." But what if that neighborhood doesn't have sidewalks, and is cut off from other parts of the community? What if residents in that neighborhood feel unsafe when walking around because of poor lighting or other issues? What if children can't play because of lack of space?

Confronting our nation's health crisis requires that we support individuals and communtiies in making better choices, and that we work together to address the underlying conditions and other factors - stress, poverty, social isolation, and neighborhood safety - that contribute to declining health and well-being. This is especially important for those living in communities with limited access to the tools and resources needed to attain and maintain a healthier lifestyle.

We need to make the healthy choice the easy choice by ensuring that our communities have adequate opportunities for children, families and adults to engage in healthy behaviors in all of the places where they live, work, learn, and play.

The Y, along with many other national and local organizations, is part of a growing "healthier communities" movement around the nation, bringing together community leaders and advocates to transform environments and to ensure that healthy opportunities are available to all - no matter where they live.

These collaborative efforts are making getting fit by active transportation easier by creating streets that are safe for all users whether they walk, bike or drive. They are making it easier for kids to walk to school by providing walking school buses and designated walk-to-school days. They are building or repairing parks or playgrounds, thereby providing opportunities for kids and families to play together. They are connecting communtiies by building walking and bike paths. They are ensuring that town and city plans address community design to ensure they support physical activity - and so much more.

A healthier community is a stronger community, leading not only to improved chronic disease and obesity rates, but often an improved economy. Imagine a neighborhood where businesses that struggled suddenly thrive after new street lighting makes it possible to shop at night. Imagine children playing in a new park. Imagine a new bustling town businesses district that is connected to residential neighborhoods through pedestrian and bike trails.

The possibilities are limitless, but it will take all parts of a community working together to achieve the goal of healthy communities where opportunities for physical activity benefit everyone.

What kind of barriers to physical activity might communities face? What are some things that communities can do together to overcome those barriers? Who might need to work together to help support physical activity in these communities? What ares ome of the benefits, outside of improved physical health, that healthier communities can lead to?

To health professionals, planners and transportation experts, active transportation (i.e. walking and biking as an alternative to car travel) is a no-brainer. Communities that facilitate non-motorized modes as safe and convenient options for getting from A to B simply function better. They have less pollution, their population is healthier, downtown business areas are more vibrant, and real estate values are stronger as their neighborhoods reflect what more Americans are demanding of their environments these days - diversity of transportation choices.

Not only that, but these facilities make economic sense too. A mile of paved trail can cost the same as just a few yards of urban four-lane road, not to mention the associated savings of non-motorized transportation stemming from reduced oil consumption and spending on reactive health care. This is why building environments that encourage walking and bicycling is a key part of the National Physical Activity Plan, and a major component of its strategies.

Unfortunately, despite the overwhelming support of the public health community, local planners and officials, businesspeople and residents, there are still some political and financial barriers to building these kinds of environments. For example, the Transportation Enhancements (TE) program was recently an agenda item during government budget planning. TE is the nation's largest funding source for trails, walking and bicycling. Working with numerous partners, Rails-to-Trails Conservancy (RTC) led an effort to ensure our elected leaders knew how important walking and biking options were to their constituents. In the end, vital active transportation programs like TE were preserved intact.

RTC knows it is important to secure adequate funding for active transportation into the future. So, what we know to be a public health issue - the effort to increase physical activity in our everyday lives - is also an effort of political will.

In an era of fiscal constraint, presenting economic benefits could have the most weight when discussing the issue with policymakers. With walking and biking, it is an easy argument to make.

Biking and walking infrastructure account for less than two percent of the entire federal surface transportation budget, yet account for 12 percent of all trips taken in America. And trail construction projects have been shown to create more jobs, and more local jobs, for every $1 spent, than road construction. This is both smart financial investment and good health policy.

The voice of the health community, which understands so clearly that investing in walking and biking could translate into a significant reduction in our health care expenditure, adds yet another dimension to a case that is already hard to dismiss.

The great work being done through the National Physical Activity Plan will only be realized as health gains if we are able to maintain funding and support for facilities that encourage biking, walking, and active ways of getting around.

How will you encourage the funding of facilities that promote active transportation?

The National Physical Activity Plan is an ambitious, comprehensive, and vital blueprint for creating a more active culture. It embodies the principles and best ideas formulated by folks steeped in the urgent effort to increase physical activity among all Americans. Already it is having an impact.

But there is a significant barrier. And it is one that must be overcome before the vision of the Plan can be fully realized.

It is the misconception that the ultimate goal of the National Physical Activity Plan is to promote physical activity. It isn't.

The ultimate goal of the National Physical Activity Plan is to save lives - millions of lives - and to improve the overall health and wellbeing of every American.

It is a goal worthy of the full attention of policymakers and thought leaders. And given the staggering cost of obesity and chronic diseases in this country - coupled with the dismal forecast for the life expectancy of America's current generation of children - it is a seriously urgent goal that requires immediate action.

Last month, the United Nations (UN) General Assembly held a high-level meeting to discuss the devastating impact that non-communicable diseases (NCDs) are having around the world. Not surprisingly, they reached the very conclusion that prompted the development of our country's own National Physical Activity Plan two years ago:

The resolution that resulted from the meeting recognized "the critical importance of reducing the level of expsoure of individuals and populations to the common modifiable risk factors for non-communicable diseases, namely, tobacco use, unhealthy diet, physical inactivity, and the harmful use of alcohol, and their determinants while at the same time strengthening the capacity of individuals and populations to make healthier choices and follow lifestyle patterns that foster good health."

In a recent editorial published by McClatchy Newspapers, Joe Moore, President and CEO of the International Health, Racquet & Sportsclub Association (IHRSA), connected the pressing nature of the UN resolution directly to the National Physical Activity Plan.

"As UN members formulate a coordinated strategy to prevent and control NCDs around the globe, we need to consider our own efforts," Moore wrote. "What can we do, as a united nation, to fight back the NCDs that we've let grow out of control in our own backyards?"

He continues, "Our country's first-ever National Physical Activity Plan lays out a vision that one day, all Americans will be physically active and will live, work, and play in environments that facilitate regular physical activity. Its ultimate purpose is to improve health, prevent disease and disability, and enhance quality of life."

In short, the National Physical Activity Plan is about making America strong again.

And that demands attention.

What are your ideas on what else we can do to emphasize the urgency of the National Physical Activity Plan? How do we get policymakers and opinion leaders to pay attention? What is your organization doing?
