The Effect of combined training (resistance – aerobic) on BMD and some of blood markers in obese and overweight postmenopausal women

The purpose of this study was to investigate the effect of 12 weeks of combined exercise on bone mineral density and some blood parameters in postmenopausal women with overweight. 29 inactive postmenopausal women with an age range of 58 to 46 years participated in this study. Subjects were placed in one of the two exercises (resistance-aerobic) and control (without exercise). Before and after the training period, weight, body mass index, fat percentage, bone density of the lumbar vertebrae and femoral head (in dexas), calcium and serum phosphorus were measured. The exercise protocol included upper and lower resistance exercises in 3 sets with 12 to 8 repetitions, and aerobic training including running and waving alternately for 12 weeks and 3 sessions per week. The data with normal distribution were analyzed using ANOVA and T-Paired methods and data without normal distribution using KruskalWallis and Wilcoxon. The experimental group showed a significant increase in serum calcium, bone density in the lumbar spine and neck (P<0.05). There was a significant decrease in weight, fat percentage and body
mass index (P<0.05). Serum phosphorus did not change significantly (P<0.05). The findings showed that in order to maintain or prevent the reduction of bone density, postmenopausal women are recommended to combine resistance and aerobic exercises
