Commentary: Rona Macniven, Prevention Research Collaboration, University of Sydney Adolescence is known to be a period of time where physical activity levels decline and weight increases so it is therefore an optimum opportunity for health interventions. This international study looked at the science around inflammatory biomarkers present in blood samples ...
Introduction Self-reported sleep duration is widely used but may not provide accurate information. Correlations between objective estimates of sleep and self-reported data only demonstrate if a relationship is present but do not determine if the two measures agree. We sought to determine levels of agreement between two self-reported average weekday ...
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. ...
Physical activity can benefit the health of youth with Type 1 diabetes. Despite the benefits some studies have found patients do not always meet the physical activity recommendation of 60 minutes of moderate-to-vigorous physical activity (MVPA) per day. Physical activity and sedentary behaviour have not been measured previously in Scottish youth with ...
In recent years, the risks associated with sedentary behavior (i.e. obesity, Type II diabetes) have become more recognized. Knowledge of the time-of-day when individuals are most sedentary may be beneficial when designing program interventions to promote and increase physical activity. Purpose To examine time-of-day patterns of sedentary behavior in ...
Various sets of prediction equations for the Actigraph have been developed to estimate energy expenditure (EE) in youth, but there is no consensus about the best approach. A set of two 2-regression models (2RM) have been proposed as alternative to traditional single regression models (1RM), but they have not been ...
Purpose The purpose of this study was to examine the use of the ActivPAL (AP) and ActiGraph GT3X (AG) for estimating SB during structured and free-living physical activity (PA) in youth. Methods Twenty-nine boys and 23 girls (mean±SD; age, 12±0.9 yrs; BMI 23.3±5.8 kg.m-2) performed up to 8 structured activities and ...
Introduction In México, despite the important issue of obesity and overweight, little is known regarding the relationship of physical activity and their related health issues, especially in the adolescent population Purpose To evaluate in a group of sophomore high school students the amount of physical activity measured by accelerometry ...
The purpose of this review was to examine the factors that predict the development of excessive fatness in children and adolescents. Medline, Web of Science and PubMed were searched to identify prospective cohort studies that evaluated the association between several variables (e.g. physical activity, sedentary behaviour, dietary intake and ...
PURPOSE: To determine whether time spent in objectively measured physical activity is associated with change in body mass index (BMI) from ages 9 to 15. DESIGN AND METHODS: The participants were enrolled in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development (n = 938). At ...
