Bone Mass in Prepubertal Tennis Players.
International Journal of Sports Medicine, 2010
To assess if exercise before puberty affects bone mineral content (BMC) and bone mineral density (BMD) we determined BMC and BMD in the dominant arm (DA) and non-dominant arm (NDA), lumbar spine and femoral neck in 25 tennis players (TP), 21 soccer players (SP) and 22 physically active controls (CG).
In TP the DA was heavier than the NDA (7.50.8%), due to a greater lean mass (10.21.2%) and BMC (16.32.2%).
Inter-arm asymmetry in lean mass, BMC, BMD and bone area was significantly higher in TP than in SP and CG.
In conclusion, tennis participation before puberty is associated with increased lean mass and bone mass, due to an enhanced bone size and areal BMD in the playing arm.
