ABSTRACT
Several key topics in the long history of paediatric work physiology research are highlighted in the title. Youth are the children and adolescents who are the focus of research. Sport is perhaps the most popular and visible context of physical activity (PA) among youth. PA is a topic of heightened public health interest. Organized youth sports are a major feature of the lives of children and adolescents in many parts of the world, and are driven largely by adults – administrators, coaches and parents.
