The Effect of a Multicomponent Dual-Modality Exercise Program Targeting Osteoporosis on Bone Health Status and Physical Function Capacity of Postmenopausal Women

Abstract

Purpose: Exercise is important for the prevention of osteoporosis and the reduction of fracture risk because it improves muscle mass and strength, besides improving balance. We evaluated the effect of a specific exercise program on bone mass and quality and physical function capacity in postmenopausal women with low bone mineral density. Methods: Participants (N = 125) underwent a bone mass (Dual X-ray Absorptiometry), bone quality (osteosonography), and physical functional capacity assessment. Fifty-eight of them took part in an 11-month exercise program (E), that included a multicomponent (strength, aerobic capacity, balance, joint mobility) dual-modality (on ground and in the water; alternating group and home-based exercise periods) exercise regimen. The others represented a control group (C) that did not exercise. After the exercise program all participants were reevaluated. Results: After the training program: femoral neck T-score significantly improved in E; C significantly decreased all bone quality (osteosonography) parameters, whereas E showed no differences; E significantly improved all the physical function capacity parameters, while most of them decreased or did not change in C. Conclusions: A specific exercise program targeting osteoporosis improves physical function capacity, reduces physiological bone loss, and maintains bone quality in low bone mineral density postmenopausal women.
