Introduction: Cognitive function (CF) is responsible for mental and intellectual processes. The effects of physical activity (PA) on cognition are likely to be over brain structure and function. During childhood, nervous system structures are growing fast representing a crucial period for cognitive development.
Purpose: Analyze both cross-sectional and longitudinal associations ...
Abstract: The Czech Republic lacks body composition (BC) and physical activity (PA) data for children. Therefore, the purpose of the study was to analyze BC and PA in sample of Czech children and to find a gender-specific association between these variables. In this study we analyzed data of 129 children (75 girls) ...
Purpose: Impact loading of bone is thought to be an important prevention for osteoporosis throughout life. The purpose of this study was to assess validity of accelerometers that provide raw acceleration signals with ground reaction force (GRF) for daily physical activities in children. Understanding error of these devices is a ...
Aim: The aim of this study was to assess time trends in objectively assessed physical activity in a population based sample of children and adolescents living in Norway.
Methods: The sample population (n=4766) consists of two independent samples of 9- and 15-year-old children recruited within the PANCS project in 2005-06 ...
Background: Physical activity and sedentary behaviour of South African preschool children has not been previously assessed, nor has the impact of socioeconomic status on these behaviours. Methods: Physical activity was measured objectively using Actigraph GT3X+ accelerometers on children 3-6 years old, including children from low income (n=87) and high-income (...
Purpose: There is considerable debate about the possibility of physical activity compensation. This study examined whether increased levels in physical activity and/or sedentary behaviour on one day were predictive of lower levels in these behaviours the following day (compensatory mechanisms) among children.
Methods: Two hundred and forty-eight children (121 boys, 127 ...
Background: Moderate-to-vigorous physical activity (MVPA), and more recently, sedentary behaviour, have well recognised health consequences. However, academic sequelae are less well understood. Some educators assert that promoting MVPA and discouraging sedentary behaviours in schools is important to maximise academic outcomes. Aim: To examine associations between MVPA, sedentary behaviour and academic ...
Introduction: South Asian (SA) school-aged children are reported to be less active than White Europeans, which may contribute to poor current and/or future health. However, research in pre-schoolers is scarce. This study examined ethnic differences in objectively assessed physical activity (PA) and sedentary time of pre-schoolers from a multi-ethnic ...
Purpose: Most studies of neighbourhood features examine singular neighbourhood attributes, which may pattern in different ways. This study aimed to identify typologies of neighbourhood attributes and their associations with physical activity among children.
Methods: The homes of 808 children aged 5-6 and 10-12 years were mapped in a Geographic Information System. ...
Abstract: Active commuting to school (ACS) is an important source of physical activity for young people and may be helpful in fighting the obesity epidemic. However, children are subject to their parents restrictions and are not totally independent when choosing their active behaviors. The aim of this study is to ...
