There is a positive association between attending leisure time sports and bone bone mineral content, bone mineral density and bone area among children.

The impact on children's bone health of a school-based physical education program and participation in leisure time sports: The Childhood Health, Activity and Motor Performance School (the CHAMPS) study, Denmark.

The studyd evaluate the effect of a school based physical education (PE) program and the amount of leisure time sport (LTS) on children's bone health and to examine if LTS influences the impact of school type on children's bone health.
Children attending “sports” schools (6 × 45 min PE lessons per week) were compared to children at “traditional” schools (2 × 45 min of PE lessons per week) in Svendborg, Denmark. Whole-body DXA scans were performed at baseline (2008) and at a two-year follow-up (2010). Bone mineral content (BMC), bone mineral density (BMD), and bone area (BA) were measured. Multilevel regression analyses examined the impact of school type and LTS participation on bone.
742/800 (93%) invited children accepted to participate. 682/742 (92%) participated at two-year follow-up. Mean (SD) age was 9.5 years (0.9) at baseline. A positive association between LTS and BMC, BMD (p < 0.001) and for BA (p < 0.05) (total body less head (TBLH) and lower limb (LL)) was found. All effects regarding school type were insignificant.
