  1. Association between ambulatory physical activity and injuries during United States Army Basic Combat Training.

    Journal of Physical Activity and Health 8(4):496 (2011) PMID 21597122

    Associations between physical activity and injuries have been previously examined using self-reports. The present investigation examined this association using objective measures of activity and injury. To quantify ambulatory activity, pedometers were worn daily by recruits in 10 Army Basic Comb...
  2. Assessing cost-effectiveness in obesity: active transport program for primary school children--TravelSMART Schools Curriculum program.

    Journal of Physical Activity and Health 8(4):503 (2011) PMID 21597123

    To assess from a societal perspective the cost-effectiveness of a school program to increase active transport in 10- to 11-year-old Australian children as an obesity prevention measure. The TravelSMART Schools Curriculum program was modeled nationally for 2001 in terms of its impact on Body Mass...
  3. The place of physical activity in the time budgets of 10- to 13-year-old Australian children.

    Journal of Physical Activity and Health 8(4):548 (2011) PMID 21597128

    Low physical activity has been associated with increased fatness and deceased fitness. This observational study aimed to describe the magnitude, composition, and time-distribution of moderate-to-vigorous physical activity (MVPA) in Australian children. A total of 1132 10 to 13 year old schoolchi...
  4. A tale of two trails: exploring different paths to success.

    Journal of Physical Activity and Health 8(4):523 (2011) PMID 21597125

    This comparative case study investigates 2 successful community trail initiatives, using the Active Living By Design (ALBD) Community Action Model as an analytical framework. The model includes 5 strategies: preparation, promotion, programs, policy, and physical projects. Key stakeholders at 2 s...
  5. User demographics and physical activity behaviors on a newly constructed urban rail/trail conversion.

    Journal of Physical Activity and Health 8(4):534 (2011) PMID 21597126

    To examine demographic characteristics and physical activity (PA) behaviors of trail users on a newly constructed 2-mile urban rail/trail (ie, abandoned rail line converted to a recreational trail). A systematic evaluation process was initiated to monitor PA behaviors using the System for Observ...
  6. Active commuting to school and association with physical activity and adiposity among US youth.

    Journal of Physical Activity and Health 8(4):488 (2011) PMID 21597121 PMCID PMC3115568

    Walking or bicycling to school (ie, active commuting) has shown promise for improving physical activity and preventing obesity in youth. Our objectives were to examine, among US youth, whether active commuting was inversely associated with adiposity and positively associated with moderate-to-vig...
  7. Actical accelerometer sedentary activity thresholds for adults.

    Journal of Physical Activity and Health 8(4):587 (2011) PMID 21597132

    Actical accelerometer thresholds have been derived to enable objective measurement of time spent performing sedentary activity in children and adolescents, but not adults. Thus, the purpose of this study was to determine Actical accelerometer sedentary activity thresholds for adults. Data were a...
  8. Physical activity level and ischemic heart disease prevalence among individuals aged 45 years and older with normal weight, BRFSS, 2007.

    Journal of Physical Activity and Health 8(4):475 (2011) PMID 21597119

    Most ischemic heart disease (IHD) prevention programs that promote physical activity (PA) have focused on overweight/obese populations. Persons with normal body mass index (BMI) may mistakenly think that they are not at risk for IHD and remain physically inactive. Studies exploring the risk of I...
  9. Stability of habitual physical activity and sedentary behavior monitoring by accelerometry in 6- to 8-year-olds.

    Journal of Physical Activity and Health 8(4):543 (2011) PMID 21597127

    Accelerometry is rapidly becoming the instrument of choice for measuring physical activity in children. However, as limited data exist on the minimum number of days accelerometry required to provide a reliable estimate of habitual physical activity, we aimed to quantify the number of days of rec...
  10. Physical activity and C-reactive protein levels: the confounding role of body fat.

    Journal of Physical Activity and Health 8(4):481 (2011) PMID 21597120

    This study investigated the relationship between objectively-measured total physical activity (PA), and intensity of PA and high-sensitivity C-reactive protein (CRP) in 211 healthy, middle-age women (43.1±3.0 y). In addition, this study examined the extent to which age, BMI, abdominal circumfere...
