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, hip geometry indices, and trabecular bone score 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 yr participated in this study. Body composition and bone outcomes were measured by dual-energy X-ray absorptiometry. Maximum oxygen consumption (VO 2 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 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). VO 2 max (in liter per minute) and muscle power were positively correlated to WB BMD, total hip BMD, FN BMD, FN CSA, and FN CSMI (p < 0.05). One-repetition-maximum half-squat was positively correlated with lumbar spine trabecular bone score, WB BMD, FN BMD, FN CSA and FN CSMI (p < 0.05). This study suggests that lean mass, vertical jump, VO 2 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.

The aim of this study was to explore the relationships between performances obtained in different physical tests and bone parameters (bone mineral density [BMD], bone mineral content, hip geometry indices, and trabecular bone score [TBS]) in a group of young Lebanese overweight and obese adult men. Fifty-two overweight and/or obese (body mass index > 25 kg/m 2 ) young men whose ages range from 18 to 35 yr participated in this study. Weight and height were measured, and body mass index was calculated. Body composition, BMD, cross-sectional area and section modulus ( Z ) of the femoral neck (FN), and TBS were measured by dual-energy X-ray absorptiometry. Maximum oxygen consumption (VO 2 max, in liter per minute) was determined by direct measurement while exercising on a medical treadmill. One-repetition-maximum half-squat and maximum power ( P max) of the lower limbs were measured using validated exercises. Lean mass was a positive determinant of whole-body bone mineral content ( r  = 0.71, p  < 0.001), FN cross-sectional area ( r  = 0.51, p  < 0.001), and FN Z ( r  = 0.58, p  < 0.001). VO 2 max (in liter per minute) was a positive determinant of whole-body BMD ( r  = 0.47, p  < 0.001), total hip BMD ( r  = 0.43, p  < 0.01), and FN BMD ( r  = 0.42, p  < 0.01). VO 2 max (in milliliter per minute per kilogram) was a positive determinant of TBS ( r  = 0.30, p  < 0.05). One repetition maximum was a positive determinant of L1–L4 BMD ( r  = 0.33, p  < 0.05). This study suggests that VO 2 max (in liter per minute) is a positive determinant of BMD, and VO 2 max (in milliliter per minute per kilogram) is a positive determinant of TBS in overweight and obese men.
