The aim of the present study was to explore the relations between muscular maximal strength indices and bone parameters (bone mineral density, hip geometry indices and trabecular bone score) in a group of elderly women. This study included 35 healthy elderly women whose ages range between 65 and 75 years (68.1 ± 3.1 years). Bone mineral density (BMD, in gram per square centimeter) was determined for each individual by DXA at the whole body (WB), lumbar spine (L1–L4), total hip (TH) and femoral neck (FN). L1–L4 trabecular bone score (TBS) and hip geometry indices were also evaluated by DXA. Maximal muscle strength of bench press (1-RM bench press), maximal muscle strength of leg press (1-RM leg press) and Handgrip (HG) were measured using validated methods. 1-RM bench press was positively correlated to TH BMD (r = 0.40, p < 0.05), FN BMD (r = 0.41, p < 0.05), FN Z (r = 0.33, p < 0.05) and FN CSMI (r = 0.35, p < 0.05). 1-RM leg press was positively correlated to TH BMD (r = 0.50, p < 0.01), FN BMD (r = 0.35, p < 0.05), FN CSA (r = 0.38, p < 0.05) and TBS (r = 0.37, p < 0.05). HG was only correlated to FN CSMI (r = 0.43, p < 0.01). This study suggests that 1-RM bench press and 1-RM leg press are positive determinants of BMD in elderly women.
