Validity and Reliability of Fitbit Flex for Step Count, Moderate to Vigorous Physical Activity and Activity Energy Expenditure

  • Published on Sep 2, 2016

Objectives: To examine the validity and reliability of the Fitbit Flex against direct observation for measuring steps in the laboratory and against the Actigraph for step counts in free-living conditions and for moderate-to-vigorous physical activity (MVPA) and activity energy expenditure (AEE) overall. Methods: Twenty-five adults (12 females, 13 males) wore a Fitbit ...


Disparities in moderate-to-vigorous physical activity among girls and overweight and obese schoolchildren during school- and out-of-school time

  • Published on Mar 22, 2016

Background: Increasing physical activity (PA) during the school day and out-of-school time are critical strategies for preventing childhood obesity and improving overall health. The purpose of the present investigation was to examine schoolchildren’s volume and type of PA during school-time and out-of-school, compared to national recommendations and differences by ...


Places where preschoolers are (in)active: an observational study on Latino preschoolers and their parents using objective measures

  • Published on Feb 29 2016

Background: To combat the disproportionately higher risk of childhood obesity in Latino preschool-aged children, multilevel interventions targeting physical (in) activity are needed. These require the identification of environmental and psychosocial determinants of physical (in) activity for this ethnic group. The objectives were to examine differences in objectively-measured physical activity and ...


Measuring moderate-intensity walkingin older adults using the ActiGraph accelerometer

  • Published on 2016

Background: Accelerometry is the method of choice for objectively assessing physical activity in older adults. Many studies have used an accelerometer count cut point corresponding to 3 metabolic equivalents (METs ) derived in young adults during treadmill walking and running with a resting metabolic rate (RMR) assumed at 3.5 mL · kg−1·...


Comparison of Consumer and Research Monitors under Semistructured Settings

  • Published on Jan 2016

Purpose: This study evaluated the relative validity of different consumer and research activity monitors during semistructured periods of sedentary activity, aerobic exercise, and resistance exercise. Method: Fifty-two (28 male and 24 female) participants age 18-65 yr performed 20 min of self-selected sedentary activity, 25 min of aerobic exercise, and 25 min of resistance exercise, with 5 ...


Organized Sport Participation Is Associated with Higher Levels of Overall Health-Related Physical Activity in Children (CHAMPS Study-DK)

  • Published on Aug. 11, 2015

Introduction: Many children fail to meet international guideline recommendations for health-related activity (≥60 minutes/day of moderate-to-vigorous physical activity [MVPA]), and intervention studies to date have reported negligible effects. Objective: Explore the associations of organized leisure-time sport participation with overall physical activity levels and health-related physical activity guideline concordance. Methods: ...


Energy Intake and Energy Expenditure Assessment of Male Adolescent Academy-Level Football Players

  • Presented on July 3, 2014

The purpose of this study was to provide further insight into the limited amount of data that exists on both the dietary practices and energy expenditure of adolescent academy-level football players. Ten male adolescent football players, representing a professional club at academy level (mean ± SD: 15.4 ± 0.3 years; height 1.7 ± 0.1...


Perceptions of empowering and disempowering coach created climates as predictors of objectively measured daily physical activity and sedentary time in youth sport participants

  • Presented on May 21, 2014

Purpose: Grounded in self-determination theory (Deci and Ryan, 2000) and achievement goal theory (Ames, 1992, Nicholls, 1989) this study tested a hypothesised model linking perceptions of the coach-created motivational climate within youth sport (i.e., empowering and disempowering dimensions; Duda, 2013), to motivation regulations and objectively measured daily moderate-to-vigorous physical activity (MVPA) and sedentary ...


Objective Assessment of Sedentary Behavior during and after Prolonged, Intensive Aerobic Exercise Training

  • Presented on May 29, 2014

Background: Observational studies have shown that individuals can be both highly sedentary and highly active, and active people sit as much as those who do not meet the physical activity guidelines. It is not known how sedentary behavior changes in response to significant exercise training, such as training for ...


Quantifying the Intensity of Recreational Golf

  • Presented on May 28, 2014

Background: Participation in moderate physical activity (PA) as a means of eliciting health-related benefits is consistently recommended through the 2008 Physical Activity Guidelines and the ACSM-AHA Physical Activity Recommendations. Many try to meet this requirement by participating in PA that fit both their functional abilities and personality. However, quantifying the intensity ...
