Eight months of regular in-school jumping improves indices of bone strength in adolescent boys and Girls: the POWER PE study.
The POWER PE study was an 8-mo , r and omized , controlled , school-based exercise intervention design ed to apply known principles of effective bone loading to practical opportunities to improve life-long musculoskeletal outcomes . A total of 99 adolescents ( 46 boys and 53 girls ) with a mean age of 13.8 + /- 0.4 yr ( peri- to postpubertal ) volunteered to participate . Intervention subjects performed 10 min of jumping activity in place of regular physical education ( PE ) warm up . Control subjects performed usual PE warm-up activities .  Bone mass ( DXA and QUS ) was assessed at baseline and follow-up along with anthropometry , maturity , muscle power , and estimates of physical activity and dietary calcium . Geometric properties ( such as femoral neck [ FN ] moment of inertia ) were calculated from DXA measures . Boys in the intervention group experienced improvements in calcaneal broadb and ultrasound attenuation ( BUA ) ( + 5.0 % ) and fat mass ( -10.5 % ) , whereas controls did not ( + 1.4 % and -0.8 % , respectively ) . Girls in the intervention group improved FN BMC ( + 13.9 % ) and lumbar spine ( LS ) BMAD ( + 5.2 % ) more than controls ( + 4.9 % and + 1.5 % , respectively ) . Between-group comparisons of change showed intervention effects only for whole body ( WB ) BMC ( + 10.6 % versus + 6.3 % ) for boys . Boys in the intervention group gained more lean tissue mass , trochanter ( TR ) BMC , LS BMC , and WB BMC and lost more fat mass than girls in the intervention group ( p < 0.05 ) . Ten minutes of jumping activity twice a week for 8 mo during adolescence seems to improve bone accrual in a sex-specific manner . Boys increased WB bone mass and BUA , and reduced fat mass , whereas girls improved bone mass at the hip and spine
