The New Majority: Pedaling Towards Equity.
Showcases stories of powerful local efforts opening up new lanes to bicycling in communities too often overlooked by traditional transportation planners and bicycling advocates. Intended to be a conversation-starter rather than a comprehensive analysis, the report highlights new data, analysis and organizational profiles that show women, youth and people of color are playing a key role in making bicycling safe, accessible and inviting in diverse communities

The Relationship Between Self-Determined Motivation and Physical Activity in Adolescent Boys
Journal of Adolescent Health In Press, Corrected Proof
The findings of this study suggest that motivation is an important correlate of adolescent boys' physical activity levels in PE lessons and during leisure-time. Also, results indicated that teachers' behavior could be an important determinant of physical activity in PE lessons, while individual motivation may be important in leisure-time.

No single study has definitively identified a precise and unyielding steps/day value for youth. Considering the other evidence to date, we propose a reasonable ‘rule of thumb’ value of≥11,500 accelerometer-determined steps/day for both children and adolescents (and both genders), accepting that more is better. For practical applications, 9,000 steps/day appears to be a more pedometer-friendly value.

Take a look at this new initiative in the U.S which provides training and technical assistance to help municipal officials adopt policies that improve access to physical activity and healthy food in their communities.

Three Frameworks to Predict Physical Activity Behavior in Middle School Inclusive Physical Education: A Multilevel Analysis
Adapted Physical Activity Quarterly Volume 30, Issue 3, pgs 254-270, July 2013
The findings suggest that the ecological framework should be considered to effectively promote PA of adolescents with and without disabilities in middle school PE classes.

Adherence to and efficacy of home exercise programs to prevent falls: a systematic review and meta-analysis of the impact of exercise program characteristics
Database of Abstracts of Reviews of Effects. A critical abstract by the Centre for Reviews and Dissemination found that: Despite limitations in the included trials and in the analyses, and high variability, the conclusions of the review were cautious and broadly reflect the evidence, making them likely to be reliable.

These results confirm the effectiveness of structured walking interventions with systematic training progression and underscore the value of community-based senior organizations as intervention settings for older adults.

The purpose of this review is to update expected values for pedometer-determined physical activity in free-living healthy older populations…. The range of 2,000–9,000 steps/day likely reflects the true variability of physical activity behaviors in older populations. More explicit patterns, for example sex- and age-specific relationships, remain to be informed by future research endeavors.

This research looked at how important everyday physical activity was in maintaining enough blood flow to the brain.

They found “the evidence suggests that 30 minutes of daily MVPA accumulated in addition to habitual daily activities in healthy older adults is equivalent to taking approximately 7,000-10,000 steps/day. Those living with disability and/or chronic illness (that limits mobility and or/physical endurance) display lower levels of background daily activity, and this will affect whole-day estimates of recommended physical activity.”

A step-defined sedentary lifestyle index: less than 5000 steps/day
Applied Physiology, Nutrition, and Metabolism, 2013, 38(2): 100-114
di: 10.1139/apnm-2012-0235
Although few alternative values have been considered, the continued use of less than 5000 steps/day as a step-defined sedentary lifestyle index for adults is appropriate for researchers and practitioners and for communicating with the general public. There is little evidence to advocate any specific value indicative of a step-defined sedentary lifestyle index in children and adolescents.

The Institute of Medicine (IOM) has called upon all of America’s public schools to strengthen and improve programs and policies for physical activity and physical education in the school environment. PE teachers and educators will appreciate to see included in the IOM report’s six major recommendations a call to have the U.S. Department of Education designate physical education as a core subject.

Do Neighborhoods Make People Active, or Do People Make Active Neighborhoods? Evidence from a Planned Community in Austin, Texas
Prev Chronic Dis 2013;10:120119. doi:
This study supports the role the environment plays in physical activity. These data suggest that moving to an activity-friendly neighborhood can positively affect physical activity levels, particularly among residents who had previously been least active.

  • Having green spaces was associated with a higher likelihood of walking maintenance.
  • No green space attributes were associated with walking initiation.
  • Green spaces may be an important resource for adults to maintain walking habit.
  • Non-environmental strategies are needed to help inactive adults to take up walking.

International Journal of Behavioral Nutrition and Physical Activity 2013, 10:57
Increasing empirical evidence supports associations between neighborhood environments and physical activity. However, since most studies were conducted in a single country, particularly western countries, the generalizability of associations in an international setting is not well understood. The current study examined whether associations between perceived attributes of neighborhood environments and physical activity differed by country.

Women and Bicycles: The ins and outs of urban bicycling
This workbook is designed to be used as an educational tool in small group sessions with Roll Models to provide an initial overview on the main aspects of bicycling, through conversations and activities.

Creating Healthy Workplaces - Prolonged sitting
Learn about the effects of prolonged sitting and what can be done to minimize their impact in this video created for Vic Health as part of their creating healthy workplaces program.

Obesity Article first published online: 29 MAY 2013

Participation in this 4-month, pedometer-based, physical activity, workplace health program was associated with sustained improvements in chronic disease risk factors at 12 months. These results indicate that such programs can have a long-term benefit and thus a potential role to play in population prevention of chronic disease.
