The aim of this study was to assess the impact of a program of supervised physical exercises (WEB protocol) versus home-based exercises on body composition (lean mass and fat mass) in postmenopausal women.
The initial sample comprised 60 women who were randomized into two groups. After exclusion, the final randomized sample included a supervised group (n = 16; mean age, 66.4 ± 6.5 y) and a home group (n = 18; mean age, 68.2 ± 6.0 y). Both groups underwent a 12-month intervention with physical exercises, including muscle impact exercises and strength and stretching consisting of two weekly sessions of 60 minutes. Body composition was determined by densitometry.
The supervised group exhibited increased lean mass in the upper limbs (P = 0.003) and lower limbs (P = 0.011), total lean tissue (P = 0.015), and appendicular lean mass index (P = 0.001) compared with baseline. The home group exhibited no differences in the lean mass assessments.
Our results suggest that regular supervised physical exercises with free weights and elastic bands can promote greater improvements in lean body mass than unsupervised exercises in postmenopausal women.
本研究旨在评估监督下的体育锻炼计划（WEB方案）与居家锻炼对绝经后女性身体成分（瘦体重和脂肪量）的影响。
初始样本包括60名女性，她们被随机分为两组。排除部分样本后，最终随机样本包括一个监督组（n = 16；平均年龄，66.4 ± 6.5岁）和一个居家组（n = 18；平均年龄，68.2 ± 6.0岁）。两组均接受为期12个月的体育锻炼干预，包括肌肉冲击运动以及力量和拉伸运动，每周进行两次，每次60分钟。通过密度测定法确定身体成分。
与基线相比，监督组上肢（P = 0.003）和下肢（P = 0.011）的瘦体重、总瘦组织（P = 0.015）和附属瘦体重指数（P = 0.001）均有所增加。居家组在瘦体重评估方面没有差异。
我们的结果表明，在绝经后女性中，与无监督的锻炼相比，使用自由重量器械和弹力带进行定期监督下的体育锻炼能更有效地促进瘦体重的改善。
