To investigate the reliability of a muscle strength test of the arm/shoulder in elderly people, aged 75 and older, and to compare subjects with and without previous muscle strength training experience.
Reliability study - test-retest.
Research centre for the elderly.
One repetition maximum (1 RM) was measured using an arm/shoulder strength-training device (Pull Down, Norway). Two measurements were conducted, approximately one week apart.
Forty people were included in the study and 34 completed both sessions. Eleven participants had previous muscle strength training experience on the indicated device. There was a high correlation between the test sessions, r = 0.97 for both groups. The analysis of 95% limits of agreement for the mean difference was -4.3/+6.9 kg for the group without and -3.0/+6.4 kg for the group with previous experience, respectively.
One repetition maximum evaluated by the Pull Down device seems to be a reliable and safe method for dosing and evaluating a muscle strength training programme for elderly people. The observed variation of approximately -4/+7 kg cannot be interpreted as an effect of muscle training, but is more likely an effect of learning, fluctuations in daily condition and/or motivation.
研究75岁及以上老年人手臂/肩部肌肉力量测试的可靠性，并比较有和没有先前肌肉力量训练经验的受试者。
可靠性研究——重测。
老年研究中心。
使用手臂/肩部力量训练设备（挪威的下拉式器械）测量一次重复最大值（1RM）。进行了两次测量，间隔约一周。
40人纳入研究，34人完成了两个阶段的测试。11名参与者曾在指定设备上进行过肌肉力量训练。测试阶段之间存在高度相关性，两组的r均为0.97。无先前经验组平均差异的95%一致性界限分析为-4.3/+6.9千克，有先前经验组为-3.0/+6.4千克。
通过下拉式器械评估的一次重复最大值似乎是为老年人制定和评估肌肉力量训练计划的可靠且安全的方法。观察到的约-4/+7千克的变化不能解释为肌肉训练的效果，而更可能是学习、日常状况波动和/或动机的影响。
