Physical activity has various health benefits. Active transport can contribute to total physical activity and thus affect body weight because of increased energy expenditure. This review summarizes published evidence on associations of active transport, general physical activity, and body weight in adults.

The Pedestrian and Bicycle Information Center, in conjunction with Toole Design Group, has created a new website to serve as a clearinghouse for Bike Share resources. The site features the latest research and information on bike share programs, including guidelines for creating programs, as well as links to existing bike share systems around the world.

► Active travel can contribute to health by increasing levels of physical activity. ► Active travel is associated with good pedestrian and cycling infrastructure.
► A new bridge over the river Clyde was associated with a rise in active travel. ► Cordon counts can help monitor travel trends and evaluation of new infrastructure.

Since the middle of the last decade, Americans have been driving less and travelling by foot, bike, or transit more. The trend, they found, is led by young people, age 16 to 34.

This study reports the development, and assessment of the test–retest and internal reliability of a comprehensive proxy survey instrument designed to measure correlates of preschool children's physical activity across the three domains of the social ecological model.

Uses both parent-reported and directly measured (accelerometry) data about children's activity from the 2007 to 2009 Canadian Health Measures Survey to examine moderate-to-vigorous physical activity, sedentary behaviour and sleep duration in children aged 6 to 11. The objective was to compare and contrast findings from these data collection methods, and explore differences in their associations with health markers in children.

In this new publication from the Australian Institute of Health and Welfare (AIHW), the contribution of risk factors such as physical activity and diet to chronic disease are outlined.

The 45 and Up Study is the largest study of healthy ageing ever undertaken in the Southern Hemisphere. Over 265,000 men and women aged 45 and over across NSW have been recruited – about 10% of this age group – and will have their health followed over the coming decades.

"Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life."
The purpose of this knowledge pathway is to provide evidence to support practice in the area of school nutrition policies and guidelines for public health and dietetic practitioners who are involved in the development, implementation or evaluation of school nutrition policies and school nutrition interventions.


Walking for depression or depressive symptoms: a systematic review and meta-analysis
Mental Health and Physical Activity Available online 4 April 12 In Press, Accepted Manuscript
Walking has a statistically significant, large effect on the symptoms of depression in some populations, but the current evidence base from randomized, controlled trials is limited. Thus, while walking is a promising treatment for depression or depressive symptoms with few, if any, contraindications, further investigations to establish the frequency, intensity, duration and type(s) of effective walking interventions particularly in primary care populations would be beneficial for providing further recommendations to clinical practitioners.

In this video, Streetfilms in partnership with AARP, shows the advantages of creating transit oriented neighbourhoods with a specific focus on older adults. By providing a range of mobility options Arlington, Virginia is an inspiring example of transit-oriented development that facilitates independent, active and healthy living for seniors.

Healthy Aging 2.0 proposes that 21st century information and communications technology offers public health practitioners the unique opportunity to empower, engage, and educate… older adults in chronic disease management.
The aim of this randomised control trial is to develop and evaluate a low cost, accessible, sustainable and replicable physical activity and nutrition program for older insufficiently active people aged 60 to 70 years (older Baby Boomer – young seniors group).

► We examined the role of physical activity in age related gait changes. ► Active older adults walking speeds are not reduced relative to younger adults. ► Only small changes in ankle joint mechanics with age found. ► Slight increase in hip joint moments found to compensate for changes at ankle. ► High volumes of walking in older adults may minimize age related gait changes.

Results of a new study shows that neighborhood design, such as walkability, proximity to higher quality parks and access to healthy food, has influence on obesity rates.

A Review of the Effectiveness of Physical Activity Interventions for Adult Males
Sports Medicine, Volume 42, Number 4, 1 April 2012 , pp. 281-300(20)
Males are generally under-represented in health-promotion interventions and should therefore be targeted specifically, and while results of the included studies are encouraging, there is a lack of intervention studies targeting adult males. Further research into this population group is therefore required.
SIT is a open science project setup to develop a common taxonomy (naming and classification system) of sedentary behaviours through a formal consensus process taking into account the opinion of experts and of the general public. Currently the project is under the administration of Prof D.Skelton and Dr S. Chastin at Glasgow Caledonian University.
Identifies the times during the day when people engage in moderate-to-vigorous physical activity (MVPA), based on accelerometer measures over seven consecutive days. Minutes of MVPA are reported for two-hour intervals from 7:00 a.m. to 9:00 p.m., by age group and sex, for weekdays and weekends. Patterns of physical activity among the most and least active in the population are also described. The data are from the 2007 to 2009 Canadian Health Measures Survey.

Active living is a way of life that incorporates physical activity into daily routines.   Here you can ask questions of local and national experts, explore various topics related to active living, find out what is happening in Minnesota communities around active living, as well as search for other relevant issue areas.

The focus of the PhenX (Phenotypes and eXposures) Toolkit is to provide researchers whose expertise lies outside a particular area with key measures identified by experts for uniform use in large-scale genetic studies and other extensive epidemiologic efforts going forward. The current paper specifically addresses the PhenX Toolkit research domain of physical activity and physical fitness (PA/PF), which are often associated with health outcomes

Arch Intern Med. 2012;172 (6):494-500
The authors conclude that prolonged sitting is a risk factor for all-cause mortality, independent of physical activity. Public health programs should focus on reducing sitting time in addition to increasing physical activity levels.

At all locations, cell phone PA counts were strongly associated with treadmill gait speed. Cell phones worn at the hip yielded the best predictive model. We conclude that in both men and women, cell phone derived activity counts strongly correlate with treadmill gait speed over a wide range of subject ages and weights.

There are so many reasons to be active—for mental health, fitness, disease prevention and fun.  Unfortunately, there is also a long list of reasons why people are not active enough.  These common barriers are not just excuses—they are societal realities that impact the decisions we make each and every day, including the decision to be physically active.  Whether it’s technological advances, financial pressures or psychological factors at play, we all have a lot of competing demands on our time and energy.


In this article Will Doig explores the idea that modern urban parks have become over designed and over programmed. In an effort to provide an exciting user 'experience' at every turn, Doig argues that we’ve moved away from the versatile simplicity that characterizes many of North America’s greatest parks such as Boston Commons, Prospect Park and Bryant Park.
The Toronto Centre for Active Transportation (TCAT) will launch a new Complete Streets Canada website in advance of the 2012 Complete Streets Form on April 23 in Toronto. The website will feature a new-and-improved design, new original research, fact sheets, photographs, and more!


A University of Miami study shows that women with non-metastatic breast cancer who are physically active and receive stress management intervention during treatment may reduce depression and lessen fatigue.

Twenty-three workplaces participated in the program. From baseline to follow-up, we observed significant increases in the implementation of physical activity programs (29% to 51%, P = .02), health behavior policy (40% to 46%, P = .047), and health information communication (40% to 81%, P = .001).

Public Health Volume 125, Issue 4, April 2011, Pages 210–216
The findings in this paper offer strong evidence supporting transport plans as an effective way to simultaneously reduce vehicle usage and provide health benefits through physical activity with significant increases in walking and cycling to work. This travel plan demonstrates a successful case study in increasing active travel and overall physical activity levels and can be replicated in other workplaces, together with a similarly thorough evaluation.
