本研究的目的是收集并分析 54 名 60 至 90 岁男性的平衡和肌肉表现数据。使用锐化龙伯格测试（SR）和单腿站立测试（OLST）对每只脚进行睁眼和闭眼的平衡测试。基于应变计的定量肌肉测试仪（QMT）用于测量力量的产生。所有扭矩值均标准化为体重的百分比。还记录了活动水平的自我报告。结果表明，OLST 评分与髋部屈肌、伸肌和外展肌的归一化扭矩呈正相关，SR 评分与髋部伸肌和右髋外展肌的归一化扭矩呈正相关。与那些认为自己不太活跃的受试者相比，那些认为自己非常活跃的受试者的 SR 闭眼平衡时间明显更高。那些认为自己非常活跃的受试者对于大多数测试的肌肉群也具有显着更高的标准化扭矩值。年龄和平衡时间以及年龄和力量产生之间显示出负相关关系。
The purpose of this study was to collect and analyze balance and muscle performance data obtained from 54 men aged 60 to 90 years. Balance was tested using the sharpened Romberg test (SR) and the one-legged stance test (OLST) on each foot with eyes open and eyes closed. A strain-gauge–based quantitative muscle tester (QMT) was used to measure force production. All torque values were normalized as a percentage of body weight. A self-report of activity level also was recorded. The results indicated that OLST scores and normalized torques of the hip flexors, extensors, and abductors had a positive correlation and that SR scores and normalized torques of the hip extensors and right hip abductors had a positive correlation. Subjects who considered themselves to be very active had a significantly higher SR eyes-closed balance time as compared with those who rated themselves as less active. Subjects who considered themselves to be very active also had significantly higher normalized torque values for most muscle groups tested. Negative relationships were shown between age and balance time and between age and force production.
