Gender differences in barriers to participation in after-school physical activities and related factors in Australian schoolchildren: A cross-sectional study.

Introduction: This study investigated the gender differences in reported barriers to participation in after-school physical activity (PA) and related health and socio-behavioural factors in Australian schoolchildren.
