The purpose of this study was to identify the relationships between muscle mass, muscle strength, and physical and cognitive functions and to examine the effects of resistive Theraband® exercise on sarcopenia-associated variables in the older population.
A total of 28 elderly women (age: 69.90 ± 0.8 years) participated in this study, 15 of whom underwent elastic band exercise for 1 hour per day, twice per week for 8 weeks. The correlation analysis was conducted to identify the associations between body composition, skeletal muscle mass indices, grip strength, and physical and cognitive functions. All variables were assessed at baseline and post-exercise.
Skeletal muscle mass was significantly associated with grip strength and physical function. Gait speed was positively correlated with grip strength and physical function, but not with cognitive function. Theraband® exercise significantly improved gait speed and physical function.
The present data suggest that skeletal muscle mass is highly correlated with grip strength and physical function. Eight weeks of resistive Theraband® exercise favorably affects sarcopenia by improving gait speed and mobility of elderly women.
本研究旨在确定肌肉质量、肌肉力量与身体和认知功能之间的关系，并研究抗阻Theraband®运动对老年人群中与肌肉减少症相关变量的影响。
共有28名老年女性（年龄：69.90±0.8岁）参与本研究，其中15人每天进行1小时的弹力带运动，每周两次，共8周。进行相关性分析以确定身体成分、骨骼肌质量指数、握力与身体和认知功能之间的关联。所有变量均在基线和运动后进行评估。
骨骼肌质量与握力和身体功能显著相关。步速与握力和身体功能呈正相关，但与认知功能无关。Theraband®运动显著改善了步速和身体功能。
目前的数据表明，骨骼肌质量与握力和身体功能高度相关。为期8周的抗阻Theraband®运动通过提高老年女性的步速和活动能力，对肌肉减少症产生有益影响。
