We explored whether a mechanically-assisted squat exercise improved muscle mass, muscle function, and pulmonary function in elderly women with or without sarcopenia. In total, 76 community-dwelling elderly subjects (>60 years of age) were screened. We ultimately included 30 subjects who completed more than 80% of the six-week course of mechanically-assisted squat exercises (three days per week, 30 min per day). We measured body composition, lung function, knee extensor strength, hand grip strength, and the 3-min walk distance (3MWD) before and after the exercise program. Subjects with sarcopenia had poor hand grip strength and knee extensor strength, and a slow walking speed. Their lung function parameters, including forced vital capacity (FVC), was lower than those of the controls. After six weeks of squat exercises, the hand grip strength, knee extensor strength, and 3MWD increased significantly in both groups. Appendicular skeletal muscle mass and leg lean mass were increased in subjects without sarcopenia. The FVC (L) increased significantly only in the sarcopenia group ( = 0.019). The mechanically-assisted squat exercise program increased muscle function and lung function, including FVC, in patients with sarcopenia. Muscle mass increased in subjects without sarcopenia.
我们探究了机械辅助深蹲运动是否能改善患有或未患有肌肉减少症的老年女性的肌肉质量、肌肉功能和肺功能。总共筛选了76名社区居住的老年受试者（年龄>60岁）。最终纳入了30名完成了六周机械辅助深蹲运动课程（每周三天，每天30分钟）80%以上的受试者。我们在运动计划前后测量了身体成分、肺功能、膝关节伸肌力量、握力和3分钟步行距离（3MWD）。患有肌肉减少症的受试者握力和膝关节伸肌力量较差，步行速度较慢。他们的肺功能参数，包括用力肺活量（FVC），低于对照组。经过六周的深蹲运动后，两组的握力、膝关节伸肌力量和3MWD均显著增加。未患有肌肉减少症的受试者四肢骨骼肌质量和腿部瘦体重增加。仅在肌肉减少症组中，FVC（升）显著增加（P = 0.019）。机械辅助深蹲运动计划提高了患有肌肉减少症患者的肌肉功能和肺功能，包括FVC。未患有肌肉减少症的受试者肌肉质量增加。
