背景这项研究的目的是评估在COVID-19大流行导致的独特家庭隔离条件下，健康老年受试者进行为期六个月的家庭阻力训练计划对肌肉健康和身体表现的影响。方法.这是一项随机对照研究，招募了老年参与者，他们被分配到执行六个月运动处方（EXE）的实验组或对照组（CON）。在开始时（PRE）和6个月后（POST），通过双能X射线吸收法和磁共振成像对参与者进行肌肉力量，平衡，步态评估和身体成分评估。使用D 'Agostino和Pearson检验检查数据的正态分布，并通过配对Student t检验评估PRE和POST之间的变化，而通过非配对t检验测试POST时组间的百分比和绝对变化。结果最终分析包括9名参与者：EXE，n = 5（年龄：66 ± 4; BMI：27.5 ± 3.7）和CON，n = 4（年龄：71 ± 9; BMI：24.2 ± 4.1）。EXE组仅在椅子站立试验（+19.8%，p = 0.048和ES：1.0，中度）和总脂肪量（+5.0%，p = 0.035和ES：1.4，大）中观察到显著的前后变化，组间无差异。此外，POST时EXE的大腿CSA绝对值显著高于CON（14.138 ± 2977 vs. 9039 ± 1015，p = 0.0178，ES = 1.7）。未检测到其他组内和组间差异。结论.在COVID-19爆发导致的封锁期间，基于家庭的阻力训练计划仅确定了组内下肢肌肉力量的改善，而不是老年受试者的肌肉质量和组成。居家隔离可能部分解释了由于每日PA方案减少和饮食模式改变而导致的全身脂肪增加。
Background. The aim of this study was to evaluate the effect of a six-month home-based resistance-training program on muscle health and physical performance in healthy older subjects during the unique condition of home confinement caused by the COVID-19 pandemic. Methods. This was a randomized-controlled study that enrolled older participants that were allocated to either an experimental group performing the six-months exercise prescription (EXE) or a control group (CON). At the beginning (PRE), and after 6 months (POST), participants were assessed for muscle strength, balance, gait assessment and body composition by dual energy X-ray absorptiometry and magnetic resonance imaging. Normality distribution of data was checked with the D’Agostino and Pearson test and changes between PRE and POST were assessed by paired Student’s t-test while percentage and absolute changes between groups at POST were tested by unpaired t-test. Results. Nine participants were included for the final analysis: EXE, n = 5 (age: 66 ± 4; BMI: 27.5 ± 3.7) and CON, n = 4 (age: 71 ± 9; BMI: 24.2 ± 4.1). Significant PRE-to-POST changes were observed in the EXE group only in the chair-stand test (+19.8%, p = 0.048 and ES:1.0, moderate) and in total fat mass (+5.0%, p = 0.035 and ES:1.4, large) with no between-group differences. Moreover, EXE had significantly higher absolute thigh CSA values than CON at POST (14.138 ± 2977 vs. 9039 ± 1015, p = 0.0178, ES = 1.7). No other within- and between-group differences were detected. Conclusions. The home-based resistance-training program during the lockdown period, caused by the COVID-19 outbreak, determined only within-group improvement in lower limb muscle strength but not in muscle mass and composition in older subjects. Home confinement may partially explain the increase in total body fat due to a reduced daily PA regime and altered diet pattern.
