Effects of a 20-month cluster randomised controlled school-based intervention trial on BMI of school-aged boys and girls: the HEIA study

  • Published on April 27, 2013

Background School-based interventions that target prevention of overweight and obesity in children have been tested with mixed results. Thus, successful interventions are still called for. The aim of the present study was to investigate effects of a multicomponent school-based intervention programme targeting physical activity, sedentary and dietary behaviours on anthropometric ...


Objectively measured physical activity levels of children and adolescents in rural South Africa: High volume of physical activity at low intensity

  • Published on January 15, 2013

There is limited evidence on objectively measured physical activity from Africa. This study quantified physical activity by accelerometry in rural South African children at ages 7, 11, and 15 years. Total physical activity was generally high (mean accelerometer counts per minute ranged 485–1017 across the 3 groups), but moderate- to vigorous-intensity physical activity was low: &...



ACCELEROMETER USE WITH CHILDREN, OLDER ADULTS, AND ADULTS WITH FUNCTIONAL LIMITATIONS

  • Published on January 1, 2013

Accurately assessing physical activity behavior in children, older adults, and adults with functional limitations is essential to further our understanding of determinants of physical activity behavior in these populations, and to designing, implementing, and evaluating interventions designed to increase physical activity participation. Objective methodologies to assess physical activity behavior, due ...


Associations between Neuromuscular Function and Levels of Physical Activity Differ for Boys and Girls during Puberty

  • Published on February 18, 2013

Objective To compare the associations between neuromuscular performance and anthropometric characteristics with habitual levels of physical activity in boys and girls during the initial stages of puberty. Study design In a cross-sectional study of 72 healthy children (39 boys and 33 girls) ranging in age from 8 to 14 years, sex differences in anthropometric and ...



Is walking to school associated with improved metabolic health?

  • Published on January, 2013

Background Active commuting to/from school is an important source of physical activity that has been declining over the past years. Although it is an affordable and simple way of increasing physical activity levels it is still unclear whether it has enough potential to improve health. Therefore, the aim of ...


Physical activity intensity and subclinical atherosclerosis in Danish adolescents: The European Youth Heart Study

  • Published on January, 2013

The aim was to investigate the associations between physical activity (PA), cardiorespiratory fitness (CRF) and intima media thickness (IMT) or stiffness. This was a population-based cross-sectional study (n = 336) of Danish adolescents [mean age (standard deviation, SD): 15.6 (0.4) years]. PA intensity was assessed objectively (ActiGraph model GT3X) and CRF using a ...


Estimated Energy Expenditures for School-Based Policies and Active Living

  • Published on February, 2013

Background Despite overwhelming evidence of the health benefits of physical activity, most American youth are not meeting the 60 minutes per day recommendation for moderate- to vigorous-intensity physical activity (MVPA). Policy changes have the potential to bring about substantial increases in physical activity in youth, within school and community settings. Purpose ...


The independent associations of sedentary behaviour and physical activity on cardiorespiratory fitness

  • Published on February, 2013

Background During childhood and adolescence, both physical activity (PA) and sedentary behaviour seem to influence cardiorespiratory fitness (CRF); however, the combined association of PA and sedentary behaviour remains to be understood. We analysed the combined association of objectively measured sedentary behaviour and moderate-to-vigorous intensity PA (MVPA) on CRF in Portuguese ...
