Background: Research interest in both salsa dance and Zumba fitness has increased in recent years, likely a result of the gaining popularity of these types of classes among the mainstream dance and fitness audiences. However, no investigations have yet explored the simultaneous physiological and psychological responses to attendance in community-based ...
Background: Sleep and physical activity are both important for executive function; however, few cognitive function studies include comprehensive measurement of both of these behaviors. Understanding how physical activity impacts the associations between sleep and executive function in older women is especially pertinent given the high prevalence of sleep disturbances and ...
Background: Accelerometers are increasingly used to objectively estimate free-living energy expenditure (EE) in population-based studies. Published group-level calibration equations are typically used to convert accelerometer count output into applicable EE units. The use of subject-specific calibration equations has been proposed as a way to increase the accuracy of EE ...
Background: Few randomized trials attempt to improve insulin sensitivity and associated metabolic risks in overweight youth, particularly Latino adolescents. Purpose::The aims of the present pilot study are two-fold, (a) to test the efficacy of the intervention by comparing the home-based strength training (HBST) interventions vs. control group (C); ...
Purpose: To investigate reasons for obesity in city children in China from the point view of energy metabolism balance. Methods: Fifty seven obesity (group of obesity, GOB) and overweight (group of overweight, GOV) students, averaged 9.6±0.9 years old, were selected from schools according to the BMI screening criterion for Chinese obesity ...
Background: A need exists to identify effective approaches to increase compliance with physical activity interventions conducted in community settings. Purpose: To use accelerometry to analyze the effects of bi-weekly, theoretically based motivational text messages on premenopausal women’s compliance to a walking intervention. Methods: Premenopausal women (n=52, 37.2 ± 6.2 years, 80.8% Caucasian) wore ...
Purpose: Using static, ontogenetic and multilevel allometric modelling, objectives of the study were twofold: to estimate inter- and intra-individual effects of body size descriptors on the development of LVM in adolescent boys, and to examine independent and combined effects of physical activity (PA), sedentary time and biological maturity status on ...
Background: A wide spectrum of accelerometers is used for objective assessment of physical activity (PA) and sedentary behavior (SB). However, differences in proprietary analysis algorithms of different accelerometers compromise direct comparison of PA and SB results. Purpose: To introduce a universally applicable preprocessing and analysis method for raw acceleration data. ...
Background: Several studies have shown poor heart rate variability in smokers and in physically inactive subjects. However, the correlation of HRV with pulmonary function is poorly understood. Purpose: We aimed to assess correlations between HRV and spirometric indices adjusted by the confounding effects of smoking and physical activity in daily ...
Background: It would be valuable if at risk groups with low physical activity could be identified early and offered targeted intervention. While there is an abundance of studies tracking the physical activity and sedentary behavior in children over the age of 4 years there is a of paucity data concerning ...
