摘要:Purpose: This study was carried out for determining the effect of 12-week aerobic exercise program upon bone mineral density (BMD) in pre-menopausal sedentary females. Methods: The study group included females who did not do sports regularly, did not have a special diet program and had no health problem. The participants were asked to administer a 30-minute run-walk exercise program for 3 days a week during the 12-week period. The intensity of the training was determined to be 70% according to Karvonen method. Before and after the exercises, L1-L4 was measured at T and Z score in lumbar spine, and neck, trochanter, and total BMD, calcium, phosphor, alkaline phosphatase, estradiol and parathyroid hormones were measured at T and Z score in femur neck. Wilcoxon signed ranked test was performed for comparing the pre-test and post-test values of the participants. Results: Age, height and weight averages of the participants (n=18) were determined to be 44.33±2.08 years, 155.83±4.38 cm and 75.44±7.76 kg, respectively. At the end of the study, a significant increase was determined at L1-L4 (T and Z score), calcium and phosphor values in lumbar spine (p 0.05). Conclusion: In conclusion, it was possible to consider that pre-menopausal regular and long-term medium-severity aerobic exercises decreased the risk for post-menopausal osteoporosis and depending fracture formation, and were efficient on protecting BMD.
