Mathematica Policy Research and the John W. Gardner Center for Youth and Their Communities at Stanford University conducted a randomized controlled trial of Playworks, a nonprofit organization that delivers a safe, healthy recess in low-income elementary schools in 22 U.S. cities. They collected data from students, teachers and school staff at the schools that participated in the trial. The findings are reported in four research briefs; this is the fourth of those briefs.

Physical activity during and after cancer treatment has beneficial effects on a number of physical and psychosocial outcomes. This paper aims to discuss the existing physical activity guidelines for cancer survivors and to describe future research directions to optimize prescriptions…… In conclusion, current physical activity guidelines for cancer survivors are generic, and research is needed to develop more personalized physical activity guidelines.

Here’s yet another reason to get off the couch: new research findings suggest that regularly breaking a sweat may lower the risk of having a stroke…..

The WHO/Europe has launched a policy summary and full report on promoting physical activity in socially disadvantaged groups. Scientific evidence shows that physical inactivity is a leading risk factor for ill health, and that these groups tend to have low levels of activity…... Owing to the wide range of target groups and possible interventions, the guidance avoids prescriptive recommendations. Nevertheless, socially disadvantaged groups may need more intensive support at all stages of a project, delivered through a variety of strategies that go beyond information provision.

Blue Bombers spokesperson Darren Cameron said it's great to hear that the number of people riding their bikes to games has jumped. He said at the old stadium, usually between 60 and 70 cyclists would show up. He confirms that it was 1,200 at the home opener

A Health Evidence Quality Review. Interventions to promote walking in groups are efficacious at increasing physical activity. Despite low homogeneity of results, and limitations (e.g. small number of studies using objective measures of physical activity, publication bias), which might have influence the findings, the large fail-safe N suggests these findings are robust.

While cities like New York struggle to get people onto bikes, Amsterdam is trying to keep its hordes of bikes under control. In a city of 800,000, there are 880,000 bicycles, the government estimates, four times the number of cars. In the past two decades, travel by bike has grown by 40 percent so that now about 32 percent of all trips within the city are by bike, compared with 22 percent by car.

Three quizzes: for a child, adult or motorist.  I tried the adult one – other than 2 questions related to state law the questions are very generic and apply to all.  Not all text questions – some involve diagrams of roads/cars/cyclists.

CHILDREN
A Health Evidence Quality Review. This review indicates that interventions can increase the proportion of time students spend in MVPA during PE lessons. As most children and adolescents participate in PE, these interventions could lead to substantial public health benefits.

Journal of Nutrition Education and Behavior online 11 July 2013 In Press
Nutrition and health educators work in community settings implementing lifestyle programs focused on obesity prevention and chronic disease risk reduction. These programs typically focus on improving diet and physical activity (PA) behaviors. Many nutrition educators may not be confident in their ability to select, administer, and interpret PA assessments to effectively evaluate their PA or lifestyle programs. This report will assist educators in identifying and selecting appropriate field-based assessments for measurement of PA, physical fitness, and body composition for children and adults. Specific guidelines, references, and resources are given for selecting assessment methods and test within these 3 areas.

By consciously steering kids into places and situations that allow for active play, parents can play a pivotal role in increasing their children’s physical activity levels without the expense of structured sports lessons or the time commitment to get kids to programs.

Children’s perspectives of the meaning of play are very important in determining the right activities to keep them engaged and physically active. Although existing research primarily explores adults’ understanding of play, less is known about children’s views.

A diabetes diagnosis may prompt patients to increase physical activity. Healthcare professionals should consider how best to capitalize on this opportunity to encourage increased physical activity and maintenance.

MENTAL HEALTH
A Health Evidence Quality Review.  There was a small significant overall effect for PA on depression. More outcome-focused, high-quality trials are required to effectively inform the implementation of programs to reduce depressive symptoms in children and adolescents.

OLDER ADULTS
A Health Evidence Quality Review. These studies consistently show that intensive physical rehabilitation enhances mobility and, when administered over a long period, may also improve the physical functioning of patients with dementia.

PHYSICAL ACTIVITY
This bulletin explores the nature of sport participation, including the use of a coach, training, competition, and the primary type of environment and location where Canadians participate.

This research identified a relationship between cell phone use, physical and sedentary activity, and cardiorespiratory fitness. This is the first study that we are aware of to assess these relationships in any population. Cell phone use, like traditional sedentary behaviors, may disrupt physical activity and reduce cardiorespiratory fitness.

Compared to 2006-2007, there has been no significant change in the proportion participating in sport. Gender and age disparities generally persist in both time periods.

RURAL
The physical environment of schools may influence physical activity (PA) levels of the student population. This Research File highlights a study by Hobin et al. which aimed to explore differences in time spent in PA among secondary school students attending schools in rural, urban and suburban environments, and to identify environment-level and student-level factors pertaining to between-school differences among students.

A recent research paper reveals that environmental differences in where we live and go to school do have an impact on how high school students get active and how much physical activity they tend to get.

The Relationship Between Self-Determined Motivation and Physical Activity in Adolescent Boys
Journal of Adolescent Health In Press, Corrected Proof  http://dx.doi.org/10.1016/j.jadohealth.2013.05.007
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.

Int J Behav Nutr Phys Act. 2013; 10: 49.  doi:  10.1186/1479-5868-10-49
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.

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.

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.

Int J Behav Nutr Phys Act. 2011; 8: 80. doi:  10.1186/1479-5868-8-80
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.”

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.

Highlights:
  • 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
doi:10.1186/1479-5868-10-57
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.
