Objectively measured physical activity, body composition and physical fitness: Cross-sectional associations in 9- to 15-year-old children.

abstract：:Exemplary scientific methods describe concepts and provide theories for further testing. For the field of relative age effects (RAEs) in sport, the scientific method appears to be limited to description. The purpose of this paper is to provide a theoretical model to explain RAEs in sport, which researchers can use to ...
