multicomponent school-based physical activity intervention. Our study sample included
approximately 1000 fourth grade schoolchildren from disadvantaged primary schools in Port
Elizabeth, South Africa. The specific objectives were i) to explore cross-sectional associations
and possible determinants of selective attention and academic performance; ii) to investigate
the associations between health-related quality of life, self-reported physical activity and
cardiorespiratory fitness; iii) to evaluate the effect of a 20-week school-based physical activity
intervention program on academic performance, selective attention and health-related quality
of life.
