Recent reports indicate an increase in forearm fractures in children. Bone geometric properties are an important determinant of bone strength and therefore fracture risk. Participation in non-elite gymnastics appears to contribute to improving young girls’ musculoskeletal health, more specifically in the upper body.

The primary aim of this study was to determine the association between non-elite gymnastics participation and upper limb bone mass, geometry, and strength in addition to muscle size and function in young girls.

Eighty-eight pre- and early pubertal girls (30 high-training gymnasts [HGYM, 6–16 hr/ wk], 29 low-training gymnasts [LGYM, 1–5 h r/wk] and 29 non-gymnasts [NONGYM]), aged 6–11 years were recruited. Upper limb lean mass, BMD and BMC were derived from a whole …
