Abstract The present study evaluated 117 physically active postmenopausal women (67.8 +/- 7.0 yr) who performed neuromotor physical tests (strength, balance. and mobility). Body composition (lean mass [g], fat mass [g], and % fat) and bone mineral density (BMD) of lumbar spine (L1-L4), femoral neck, and total body were measured by dual-energy X-ray absorptiometry. Following the World Health Organization criteria. osteoporosis was found in at least 1 analyzed site in 33 Volunteers (28.2%): 30 (25.6%) in lumbar spine and 9 (7.7%) in femoral neck. Body weight was strongly and positively related to BMD in all sites, but the most important component of body composition was lean mass, also significantly related to all BMD sites, whereas fat mass was weakly related to the femoral neck BMD. Percent fat did not correlate with any BMD site. of all the physical tests, the hand-rip strength was most importantly related to lumbar spine, femoral neck. and total body (r = 0.49, p < 0.001, r = 0.56, p < 0.001; and r = 0.52, p < 0.001. respectively). the static body balance presented a weak but significant positive correlation only with lumbar spine. Our results suggest that strategies aiming to improve Muscle strength and lean mass must contribute to the bone health of physically active postmenopausal women.
