Background: Post-menopausal women exhibit lower bone mineral density (BMD) and current health guidelines highlight the potential importance of reducing sedentary behavior (SB) to mitigate bone loss in this segment of the female population. Purpose: To determine if bone health status at the femoral neck (FN) and lumbar spine (LS) can ...
Background: The inter-individual variability in the effectiveness of structured exercise to achieve expected levels of weight loss or maintenance appears to be due in part to individual differences in behavioral responses that increase energy intake; however, the influence of acute exercise on dietary intake following exercise remains incompletely characterized. ...
Purpose: Currently, there are no methods to distill information from the most widely used wrist-mounted accelerometer. A field-based calibration study was conducted in order to determine cut point thresholds for this wrist-mounted accelerometer in children aged 8-12 years. Methods: Forty-five children (25 developmental; 20 cross validation) aged 8-12 years, performed up to ...
Purpose: The purpose of this study was to develop and validate physical activity (PA) cut-points for wrist (WR) and ankle (AK) accelerometer placements in youth. Methods: : For cut-point development 84 girls and 97 boys (mean ± SD; age, 12.0 ± 1.5 yrs) completed 30 min of lying rest and two to seven structured activities (from a list ...
Abstract: Travel by public transit is increasingly recognised as a ‘walk interrupted’ and therefore a potential means to engage in physical activity (PA). However, little is known about how taking public transit to and from school contributes to PA in youth. Our objective was to assess moderate-to-vigorous PA (MVPA) during ...
Background: The steep decline in physical activity (PA) among the oldest old is not well understood. Longitudinal objective PA data can give insights about how amount and bouts of PA and sedentary behaviour (SB) change with age. Methods: Men aged 70-90 years, from a UK population-based cohort wore GT3x ...
Objective: To assess the validity of the Global Physical Activity Questionnaire (GPAQ) for measuring sedentary behaviour (SB) in the Chilean adult population. Methods: 204 adults (88/116 male/female, 45.2±14.0) who were randomly selected during National Health Survey 2009-2010 completed the protocol. The participants wore an Actigraph GT3X (AG) for at least 7 consecutive ...
Abstract: The objective of this study was to estimate physical activity levels of schoolchildren during physical education classes. Thirty classes between second and fifth grades were selected from Florianópolis’ public schools, of which 13 (n=260, 50.4% boys) had attended to physical education classes. Actigraph® GT3X+ physical monitors were used to ...
Abstract: The aim of the present study was to evaluate the one-year stability of objectively-measured physical activity (PA) among individuals aged 18 to 35 years. We recruited 16 volunteers (8 men) and measured their activity levels every month from October 2012 to September 2013. GT3x+ Actigraph accelerometers were used; the epoch was set at 5 seconds. ...
Introduction: The on-going Finnish Schools on the Move programme aims to make the school day more physically active. This study investigated how school-time physical activity changed in students from grades 1 to 9 in two academic years during the pilot phase of the programme. Methods: The data was collected in 2010-2012 during ...
