Research considering physical activity (PA), physical inactivity and health outcomes among urban and rural youth has produced equivocal findings. This study examined PA, physical inactivity, sedentary behaviours and cardiorespiratory fitness (CRF) in adolescents from urban and rural communities in the Portuguese Midlands. The sample included 362 adolescents (165 males, 197 females) of 13–16 years ...
Background
The physical activity (PA) levels of many children and adolescents in Australia are currently insufficient to promote health benefits. Physical education (PE) programs aim to promote PA and reach nearly all school-aged children, but PA levels within PE lessons are often low. PE teachers may influence children's motivation to ...
Attempts to reduce the decline in physical activity (PA) in adolescence have been the focus of many public health interventions. This study aimed to (1) determine differences in moderate-to-vigorous PA (MVPA) levels between weekdays and weekends and (2) identify adolescents meeting current PA guidelines (PAG). To meet these objectives, 186 Thai adolescents aged 13 ...
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
The first aim was to examine the effect of the UP4FUN pilot intervention on children’s total sedentary time. The second aim was to investigate if the intervention had an effect on children’s physical activity (PA) level. Finally, we aimed to investigate demographic differences (i.e. age, ...
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 ...
Summary
There is an association between adiposity levels and physical activity guidelines for adolescents.
Achieving physical activity recommendations helps adolescents to prevent obesity status.
This paper presents an association between physical activity levels and obesity status.
This paper supports physical activity recommendations to avoid children's obesity levels.
This paper emphasizes ...
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 ...
In this study, we evaluated agreement among three generations of ActiGraph™ accelerometers in children and adolescents. Twenty-nine participants (mean age = 14.2 ± 3.0 years) completed two laboratory-based activity sessions, each lasting 60 min. During each session, participants concurrently wore three different models of the ActiGraph™ accelerometers (GT1M, GT3X, GT3X+). Agreement among ...
Purpose
The primary aim of this study was to objectively examine physical activity (PA) levels of girls during organized sport (OS), and to compare the levels between games and practices for the same participants. Secondary aims of this study were to document lesson context and coach behavior during practices and ...
