The aim was to assess the relationship between school rhythm and physical activity (PA) in adolescents. The study included 2024 adolescents (12.5–17.4 years). Participants wore an accelerometer for 7 days. A short school rhythm was defined as a short time at school with short recesses and less time in teaching per day (Group 1). ...
Objectives: To examine the association of health-related physical fitness components and accurate measures of fatness with attention in European adolescents. Design: Cross-sectional study. Methods: A sub-sample of 444 adolescents from the HELENA study (14.5 ± 1.2 years) from 6 different countries participated in this study. Adolescents underwent evaluations of fitness (20 m shuttle run, handgrip strength, ...
Objective: To assess the relationships among physical activity, measured objectively, and attention capacity in European adolescents. Study design: The study included 273 adolescents, aged 12.5-17.5 years, who participated in the Healthy Lifestyle in Europe by Nutrition in Adolescence Study. Participants wore a uniaxial accelerometer for 7 days to measure physical activity. The ...
Objective To assess the association between the built environment and physical fitness and physical activity in adolescents. Methods The study included 3528 adolescents, aged 12.5-17.5years, who participated in the Healthy Lifestyle in Europe by Nutrition in Adolescence (HELENA) study. The health-related physical fitness components were assessed using the physical fitness ...
Background Adequate sleep is a critical factor for adolescent’s health and health-related behaviors Objective (a) to describe sleep duration in European adolescents from nine countries, (b) to assess the association of short sleep duration with excess adiposity and (c) to elucidate if physical activity (PA), sedentary behaviors and/or ...
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 ...
Background We aimed to examine whether time spent on different sedentary behaviours is associated with bone mineral content (BMC) in adolescents, after controlling for relevant confounders such as lean mass and objectively measured physical activity (PA), and if so, whether extra-curricular participation in osteogenic sports could have a role in ...
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 ...
Aim To investigate the combined influence of diet quality and physical activity on cardiovascular diseases (CVD) risk factors in European adolescents. Method Cross-sectional study that included 1513 adolescents aged 12.5‒17.5 years (45% boys) from eight European countries participating in the HELENA study. Dietary intake was registered using a 24h recall (on two non-consecutive ...
Introduction Different types of accelerometers are available to assess physical activity (PA) patterns levels, and the choice about which to use depends on various factors: cost, physical characteristics (weight, size, and battery life), performance (number of axes, possible epochs, system of data transfer, recording duration, function of the epochs, and ...
