ACTIVE TRANSPORTATION 
The impact of snow and the Freeze-Thaw effect is included in this discussion.

Major population shifts in the United States point to changes in American attitudes and behaviors regarding walking. These shifts are likely to result in a substantial increase in both recreational and utilitarian walking. Three demographic changes, in particular, are likely to promote this “walking revolution:” (1) the aging of the baby boomers, (2) the different transportation priorities of young people, and (3) the decline of the suburbs.

In this cohort of healthy middle-aged adults, fitness was significantly associated with a lower risk of developing chronic disease outcomes during 26 years of follow-up. These findings suggest that higher midlife fitness may be associated with the compression of morbidity in older age.

Mobility, especially walking and driving, is central to healthy aging. The built environment also affects both types of mobility, but in different ways. New sources of information, such as longitudinal studies and computer simulations, are required to provide the evidence base to develop more effective, integrated public health strategies to enhance mobility in older populations.

► We examine older adults' lived experiences of aquatic activity using interviews. ► Participation was both enabling and constraining. Relationship networks altered. ► Perceptions of the aged body contribute to feelings of frailty in the pool. ► Exposure of participants' bodies created angst and fear of ridicule by ‘others.’ ► Participants internalised social values of the aging body, limiting involvement.

ACTIVE TRANSPORTATION
AT related National Traffic Safety Fact Sheets
The U.S. National Highway Traffic Safety Administration has released updated fact sheets on traffic safety related to children, older adults, pedestrians, bicyclists, rural settings, and others. The information is based on 2010 data.
 
A new report from the National Cooperative Highway Research Program investigates the policies and practices that are creating safer, more inviting environments for people on foot. It includes case studies, challenges to implementation and keys to success.

Low-Stress Bicycling and Network Connectivity
A new report from the Mineta Transportation Institute demonstrates the need for communities to take a network approach when planning for bicycling.

The Walkable and Livable Communities Institute and the U.S. Environmental Protection Agency recently published a comprehensive workbook for communities to deliver their own workshops on walkability and host a walking audit. An included Toolbox explains key concepts and provides resources for next steps.  (Download is free but you must submit basic contact information).

CHILDREN
Back to School & Back to the Future!
As the new school year approaches there's no better time to re-think the way your children travel to school. Travel behaviour is one of the hardest habits to change especially for families, so we've outlined a few small steps to help your family become the most active and healthy school commuters possible.

HASTe is a hub for groups taking action on reducing school transportation emissions in British Columbia, Canada. It's a resource and networking center, to help students, teachers and schools improve the health of individuals, communities and the environment.

Providing access to school facilities, providing unfixed equipment, and identifying ways to promote encouragement for physical activity have the potential to inform strategies to increase physical activity levels during recess periods.

OLDER ADULTS
Physical Activity in People Age 80 Years and Older as a Means of Counteracting Disability, Balanced in Relation to Frailty
Journal on Aging and Physical Activity, 20(3):317-331 (July 2012)
Focus group discussions to talk about physical activity were held with 20 people ages 80-91 who lived in the community. The four themes that emerged included physical activity as a part of all other areas of life; joy; fear of illness and dependence; and perceptions of frailty. The authors suggested that physical activity programs designed for the oldest adults emphasize that activity is part of daily living and that interventions focus on the outcomes rather than the activity itself. They advised that programs aid older adults in getting outdoors and include time for social interaction.

American Journal of Preventive Medicine Vol 43, Iss 3, Sept, Pages 329–336
http://dx.doi.org/10.1016/j.amepre.2012.05.026
Evidence suggests that exercise and leisure-time physical activity increases after the retirement transition, but whether and how total physical activity changes is unclear. Imprecise physical activity measures used in primary studies limit conclusions, and this highlights the need for further research.

OVERWEIGHT/OBESITY
Hunter-Gatherer Energetics and Human Obesity
PLOS One, 2012:7(7): e40503
This paper challenges us from an anthropological level to think about evolutionary biology and its relationship to energy expenditure. It also points to the fact that if you have a heavier population the total energy expenditure will be higher because it takes more energy to move them. Not surprisingly, hunter gathers are much more physically active than other populations and this undoubtedly contributes to their health in a number of ways.  But in terms of obeseogenesis, it maybe there are evolutionary and biological regulatory mechanisms at play, and that the amount of additional food eaten has a substantial role, given baseline physical activity levels at any level in contributing to obesity. Once again this reinforces the importance of food intake in obesogenesis, but does not negate the health consequences of inactivity at any level of industrialisation.

PHYSICAL ACTIVITY
Canadian Sport Policy 2012
The CSP 2012 sets the direction for all governments, institutions and organizations that are committed to realizing the positive impacts of sport on individuals, communities and society. The policy has been designed to be implemented by complementary action plans developed by governments individually and collectively, and by non-government organizations (NGOs) in the sport and related sectors.

Get Active Toronto (GAT) is an initiative formed between public, voluntary and private sector organizations to address the current epidemic of physical inactivity by achieving increased physical activity levels in Toronto. GAT does this by raising public awareness, creating more opportunities and reducing barriers to enable all residents to be physically active where they live, work, learn and play.

Circulation, online before print (August 13, 2012)
Inflammatory markers are proteins that underlie some disease mechanisms. For example, there is a link between higher levels of inflammation and coronary heart disease. Realizing that research in this area has primarily focused on short-term or cross-sectional studies, a team decided to look at longitudinal data to examine effects over the long term.

Health Promotion Journal of Australia Vol 23 No 2, 2012
This study evaluates the impact of community-based walking groups on increasing and maintaining regular physical activity.

URBAN DESIGN
Parks Are Part of Our Healthcare System
With the challenge of the obesity crisis and increased anxiety and depressive disorders more and more attention is being paid to the role parks play in both mental and physical health. It turns out much of the research shows that you don’t necessarily need huge million dollar investments in parks to make them health-promoting.

Electronic databases Medline, PsycInfo, CINAHL, and Web of Science were searched to retrieve English language articles published in international academic peer-reviewed journals from January 1, 1997, through December 31, 2009. Included were articles that provided descriptions of interventions designed to improve PA-related cognitive, psychosocial, and behavioral outcomes and that used randomized controlled trial design, included only children (6-12 years old) and adolescents (13-18 years old) in both intervention and control groups, and employed Internet, email, and/or short message services (SMS, also known as text messaging) as one or more major or assistive modes to deliver the intervention.

Higher levels of PA were associated with lower mortality risk in individuals with diabetes. Even those undertaking moderate amounts of activity were at appreciably lower risk for early death compared with inactive persons. These findings provide empirical evidence supporting the widely shared view that persons with diabetes should engage in regular PA.

In conclusion elderly who spend more time in physical activity or less time in sedentary behaviors exhibit improved functional fitness and other confounders. The results reinforce the importance of promoting both the reduction of sedentary behaviors and the increase of MVPA in this age group, as it may interfere at older ages in order to preserve functional fitness and performance of daily functioning tasks.

OVERWEIGHT/OBESITY 
Obesity has been linked to cancer, heart attacks and stroke. So, it's a naturally a concern when new maps show Louisiana is among the 12 states where at least 30 percent of adults are dangerously overweight. Ten of the most obese states are in the South. …Pennington researcher, Peter Katzmarzyk, Ph.D. said "Some people call it the stroke belt, the diabetes belt, the inactivity belt."

Past studies have suggested that a link between health outcomes and green space is due to increased levels of physical activity of individuals living in areas with more green space. We found a positive association between green space and physical activity levels…. These findings suggest that although there is a positive association between physical activity and green space it may not be explained by individuals using green space for recreation.

Overall engagement with the 10,000 Steps website was high, and the results demonstrate the relative effectiveness of interactive components to enhance website engagement. However, only exposure to the interactive individual challenge feature was positively associated with all website engagement indicators. More research is needed to examine the influence of intervention components on website engagement, as well as the relationship between website engagement and physical activity change.

ACTIVE TRANSPORTATION 
Not so long ago, the term “cycling studies” would have been seen as puzzling in the United States—why study what were effectively perceived as toys?.... More than 100 academic studies related to cycling have been published this year alone, including new research on the mathematical optimization of bike infrastructure, (and) the health benefits of mass cycling events. Lees-McRae College in North Carolina even offers a cycling minor.

Transportation Research Part D: Transport and Environment Volume 17, Issue 7, October 2012, Pages 525–531
Trip-end facilities at work appear to be significant determinants of cycling to work. Compared to individuals without any bicycle facilities at work, commuters with cyclist showers, clothes lockers, and bike parking at work are associated with a 4.86 greater likelihood to commute by bicycle. Individuals with bike parking, but no showers and lockers at the workplace, are associated with 1.78 times greater odds to cycle to work than those without trip-end facilities. 

A major British Medical Association report urges doctors to play a key role in reducing car use. Healthy Transport = Healthy Lives calls on the government to take a long-term view of transport policy to create the conditions that reduce demand for car use, while enabling a shift to more active and sustainable forms of transport.

Walk Appeal promises to be a major new tool for understanding and building walkable places, and it explains several things that were heretofore either contradictory or mysterious. It begins with the assertion that the quarter-mile radius (or 5-minute walk,) which has been held up for a century as the distance Americans will walk before driving, is actually a myth.

Streets and the streetscapes that surround them have several measurable things that can tell us which standard of Walk Appeal the street provides. We'll look at the things that can be measured in this post….

People on the street, lovable things along the way, and the magic of the city are three Walk Appeal factors I have no idea how to measure, but they clearly contribute to making more walkable places…..

Here's where Walk Appeal gets really interesting, and walkability theory turns into real-world survival … or thriving.

….Higher-literacy web visitors tend to scan rather than read word by word, only spending about 25 seconds on each web page. This approach to online reading has earned higher-literacy web visitors the reputation as “scanners and clickers.”

By contrast, limited-literacy web visitors are often described as “plowers” because initially they focus on one word at a time, slowly making their way through the text. However, when the going gets tough and the information looks like it may be difficult to get through, they start to scan. But they don’t become true scanners because they find it difficult to understand text simply by scanning headings and subheadings, so they quickly turn into “skippers and clickers”……

Authors' conclusions: Exercise interventions have only slight effects on physical function in frail older adults. The samples used in the included studies may not have been representative of the population so no recommendation was made as to which type of exercise was most effective.

Authors' conclusions: Fall prevention programs were modestly effective. Identifying what were the most effective components of such a program was extremely difficult and unclear from available research.
