Purpose An active lifestyle is crucial for co-morbidity prevention in pediatric cardiac transplant patients(CTxP). The purpose of this study was to evaluate daily physical activity in CTxP and to identify relationships between anthropometric measurements, cardiac function and physical activity habits. Methods Anthropometric measures and resting 2D echocardiograms were obtained. ...
Physical activity is becoming increasingly recognized as valuable to cancer patients during treatment and rehabilitation. Therefore strategies and measures to encourage patients to become more active and to achieve physical activity recommendations are of great importance. Purpose The study evaluated an accelerometer based biofeedback device by measuring the change of ...
An examination of the effects of a training program that maximizes caloric expenditure may help gain a better understanding of potential strategies that may be used in future exercise training programs targeting weight loss. Purpose The purpose of this study was to explore whether endurance training alters energy balance via ...
A physically active lifestyle and quality sleep are associated with lower risk for obesity and cardiovascular disease. Cross-sectional studies demonstrate that greater physical activity (PA) is associated with better quality sleep. However, few studies have examined this relationship using objective measures. Additionally, few studies have examined the directionality of the ...
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 To examine characteristics of accelerometer-assessed sedentary behavior among older women. Methods An ancillary study to the Women’s Health Study is collecting 7 days of accelerometer-assessed (Actigraph GT3X+) physical activity and sedentary behavior data in ~15,000 women. This analysis includes data from the first 5,032 (mean age, 70.1 yr) women with ≥4 days ...
Optimal sleep duration (7-8h), moderate-to-vigorous intensity physical activity (MVPA) and light-intensity activity are beneficially associated with cardiometabolic outcomes and related biomarkers, while sedentary time and long (≥9h) or short (<7h) sleep duration are detrimentally associated. Purpose This study examined whether sleep duration modified the relationship between both sedentary/...
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....
The ActiGraphTM is the most commonly used research grade physical activity monitor. However, the effect of the ‘low-frequency extension’ (LFE) on step counts in a free-living environment has not been widely studied. Purpose We sought to determine the accuracy of the ActiGraph’s LFE during freeliving activities in two versions ...
Accelerometers-based activity monitors are commonly used to measure physical activity energy expenditure (PAEE). Newly designed wrist and hip-worn triaxial accelerometers claim to accurately predict PAEE across a wide range of activities. Purpose To determine if the Nike FuelBand (NFB), Fitbit (FB) and ActiGraph GT3X+ (AG) accurately estimate PAEE in ...
