Aim: The benefits of promoting physical activity (PA) in counteracting the high prevalence of childhood obesity have become increasingly important in the past decade. The aim of this study was to examine the association between compliance of daily PA recommendations and the risk of being overweight or obese in preschool-aged ...
Background: Increasing school-day physical activity through policy and programs is commonly suggested to prevent obesity and improve overall child health. However, strategies that focus on school-day physical activity may not increase total physical activity if youth compensate by reducing physical activity outside of school. Purpose: Objectively measured, nationally representative physical ...
Purpose Understanding fluctuations in lifestyle indicators is important to identify relevant time periods to intervene in order to promote a healthy lifestyle; however, objective assessment of multiple lifestyle indicators has never been done using a repeated-measures design. The primary aim was, therefore, to examine between-season and within-week variation in physical ...
Background: This randomised controlled trial demonstrates the effectiveness of a value-based intervention program to encourage a physically more active lifestyle among physically inactive adults aged 30 to 50 years. The conceptual framework of the program is based on an innovative behavioural therapy called Acceptance and Commitment Therapy (ACT) that aims to increase ...
Background: Physical activity (PA) is suggested to contribute to fat loss not only through increasing energy expenditure “per se” but also increasing muscle mass; therefore, it would be interesting to better understand the specific associations of PA with the different body’s components such as fat mass and muscle mass. ...
Purpose: The purpose of this study was to develop and validate two novel machine-learning methods (soj-1x and soj-3x) in a free-living setting. Methods: Participants were directly observed in their natural environment for ten consecutive hours on three separate occasions. PA and SB estimated from soj-1x, soj-3x ...
Sedentary occupational behavior may contribute to positive energy balance and weight gain. Strategies to reduce excessive sedentary behavior and increase workplace ambulatory activity are needed. Purpose To investigate the initial effects of treadmill workstation adoption on work-related ambulatory activity and sedentary time in overweight/obese office workers. Methods Volunteers (n=17; ...
Purpose: Studies estimating the contribution of physical activity (PA) to the development of body mass index (BMI) in critical periods of childhood are warranted. Therefore, we have prospectively investigated this relationship in boys and girls of the KOALA Birth Cohort study, the Netherlands, in the period around adiposity rebound (i....
Results from several objective monitoring studies suggest that children’s physical activity (PA) patterns may change across seasons; however, it is not well understood how PA patterns in the childcare setting may change across seasons. Purpose To prospectively track preschoolers’ PA patterns during childcare while investigating for seasonal differences in ...
Background: There is little consensus on how many hours of accelerometer wear time is needed to reflect a usual day. This study identifies the bias in daily physical activity (PA) estimates caused by accelerometer wear time. Methods: 124 adults (age = 41 ± 11 years; BMI = 27 ± 7 kg/m-2) contributed approximately 1,200 days accelerometer wear time. Five 40 ...
