摘要

Purpose: To investigate the effects of 24-weeks aerobic-resistance training and yoga-resistance training on lumbar bone mineral density (BMD) in Postmenopausal Women (PMW). Methods: 19 of none regular exercise PMW who didn't receive hormone replacement therapy as the subjects (Their mean age, weight, height and body mass index (BMI) were 51.47±4.25 yrs, 57.55±5.86 kg, 1.55±0.04 m, and 24.12±2.53, respectively). Subjects were randomly divided into 2 experimental groups (EX1 and EX2, both received 3 times a week, 1hr each time training for 24 weeks, and the average attending rates were 97.90±1.80%) and control group (CON, received no training). At baseline there were no significant between-group differences with respect to BMD, weight, BMI, pain and nutritional status. Each session, EX1 included 30 minutes bench-stepping aerobics (70-80% Maximal Heart Rate) and 30 minutes resistance exercise; while EX2 subjects received 30 minutes Yoga exercise (50-60% Maximal Heart Rate) and 30 minutes resistance exercise. The lumbar BMD (scanned by DEXA) were measured prior, 12 and 24 weeks of the training program. The collected data were analyzed with one-way ANOVA. Results: Compared to CON, EX1 had significant changing rate between groups in BMD changing rate, but no difference in EX2 and other time. There was significant changing rate of BMD within group at 24th week of EX2, but no difference in EX1 and CON. Conclusions: The 24-week aerobic-resistance training maintains BMD, and yoga-resistance training can reduce the BMD changing rate of PMW respectively.
