The aim of this study was to explore the relationships between physical performance variables and bone parameters such as bone mineral density (BMD), bone mineral content (BMC), hip geometry indices, and trabecular bone score (TBS) in a group of young overweight and obese adult women. Sixty-eight overweight/obese (body mass index ≥ 25 kg/m2, 25.5 – 42.4 kg/m2) young women whose ages range from 18 to 35 years participated in this study. Body composition and bone outcomes were measured by dual-energy X-ray absorptiometry (DXA). Maximum oxygen consumption (VO2 max, in liter per minute) was determined indirectly using a progressive shuttle run test. One-repetition-maximum half-squat was directly measured. Vertical jump was measured and maximum power (P max) of the lower limbs was calculated. Lean mass was positively correlated to whole body (WB) BMD, total hip (TH) BMD, femoral neck (FN) BMD, femoral neck cross-sectional area (FN CSA) and femoral neck cross sectional moment of inertia (FN CSMI) (p < 0.05). VO2 max (in liter per minute) and muscle power were positively correlated to WB BMD, TH BMD, FN BMD, FN CSA and FN CSMI (p < 0.05). One-repetition-maximum half-squat was positively correlated with lumbar spine TBS, WB BMD, FN BMD, FN CSA and FN CSMI (p < 0.05). This study suggests that lean mass, vertical jump, VO2 max (liter per minute), muscle power and one-repetition-maximum half squat are positive determinants of BMD and hip geometry indices in young overweight and obese women.
