Summary
Physical activity declines as children enter puberty.
Leptin is cross-sectionally associated with physical activity, but there are conflicting findings on the magnitude and direction of this association.
Leptin concentrations fluctuate during puberty, and may impact energy balance.
Leptin predicts the decline in physical activity during the start of puberty ...
Background
Physical activity interventions in schools environment seem to have shown some effectiveness in the control of the current obesity epidemic in children. However the complexity of behaviors and the diversity of influences related to this problem suggest that we urgently need new lines of insight about how to support ...
High physical fitness in childhood and adolescence is positively associated with favourable health-related outcomes. Our aim was to examine the relationship between relatives' (father, mother, brother, sister, and best friend) physical activity engagement and encouragement on adolescents' physical fitness. Adolescents were part of the HELENA study, a multi-centre study conducted ...
Introduction
Participation in physical activity on a regular basis is important for maintaining health, yet many people do not meet the levels recommended by scientific and health organizations. Physical activity behavior during the late adolescence/early college period in life is of particular importance as behaviors adopted during this time ...
Introduction
School-based interventions which include efforts to increase physical activity (PA) may promote a healthy weight development in adolescents, but results are inconsistent (Brown et al., 2009). One possible explanation for low efficacy or effectiveness is limited evidence as to how interventions induce behaviour change (Baranowski et al., 2005). The purpose of ...
Introduction
There is much interest in children’s physical activity (PA), but little understanding of its control. The evidence that total activity levels could be increased by the provision of greater opportunity for physical activity is lacking.
Methods and Participants
MTI-Actigraph accelerometers recorded weekly PA in two groups of healthy ...
Purpose
To evaluate the influences of social and physical environmental factors within the home on preschoolers’ PA.
Methods
GT1M Actigraph data for 7 days were obtained in a random sample of 70 boys and 71 girls (5.4 years ± 0.3). Social (parental attitudes, knowledge, social support, rules) and physical environmental factors (play space, TV and ...
Purpose
Low levels of physical activity (PA) have been associated with increased risk of child overweight. Multiple studies show that young children are not getting the recommended 60 minutes of PA during their 8-hour day in childcare. (Reilly, 2010) This study will explored whether time spent in childcare is related to children’...
Purpose The aim of this study was to develop objective measures of park use and to describe patterns of park use and its association with moderate-to-vigorous physical activity (MVPA) among adults.
Methods From five US states, 238 adults were enrolled in or near 31 study parks. Participants wore a global positioning system (...
Purpose A number of recent studies have found associations between the characteristics of schoolyards and the level of PA of schoolchildren using the schoolyards. Based on these findings, it seems likely that making schoolyards more attractive will help to increase the total amount of PA among schoolchildren. Before starting our ...
