目的提出一种简单的单腿垂直深蹲膝伸肌肌力测量方法。本研究的目的是评估这种方法的有效性与标准的measurement.MethodsA方法比较，共30名健康成人（平均年龄22岁）和28名健康老年人（平均年龄69岁）参加了这项研究。使用身高、体重和测量的腿部前倾角度，通过几何模型计算单腿下蹲期间最大膝关节屈曲时的膝关节伸肌扭矩。通过与等速测力计和手持式测力计测得的最大等长伸肌力量进行比较，评估了该模型作为膝关节伸肌力量测量方法的有效性。结果由深蹲模型计算的膝关节伸肌力矩与等速测力计计算的膝关节伸肌力矩高度相关（r= 0.835）和手持式测力计（r= 0.884）;然而，深蹲模型和等速测力计测量值之间的差异，结论深蹲模型与手持式测力计测量值之间的相关性随肌肉力量的增加而成比例增加。定量测量膝伸肌肌力的简便方法。然而，它可能更适合四头肌肌肉无力的人比那些强壮的肌肉.Geriatr Gerontol Int 2018; 18：1125-1131.
AimWe propose a simple method to measure knee extensor muscle strength using a single‐legged vertical squat. The purpose of the present study was to assess the validity of this method in comparison with standard methods of measurement.MethodsA total of 30 healthy adults (mean age 22 years) and 28 healthy older individuals (mean age 69 years) participated in this study. Knee extensor torque at maximum knee flexion during a single‐leg squat was calculated by a geometrical model using height, weight and measured leg forward lean angle. Its validity as a measurement of knee extensor strength was assessed by comparing the results with maximum isometric knee extensor strength measured using an isokinetic dynamometer and a handheld dynamometer.ResultsKnee extensor torques calculated by the squat model were highly correlated with those calculated by the isokinetic dynamometer (r= 0.835) and handheld dynamometer (r= 0.884); however, the difference between the squat model and the isokinetic dynamometer measurements, and between the squat model and the handheld dynamometer measurements increased proportionally with increasing muscle strength.ConclusionThe squat model is a convenient way to measure knee extensor muscle strength quantitatively. However, it might be more suitable for individuals with quadriceps muscle weakness than for those with strong muscles.Geriatr Gerontol Int 2018; 18: 1125–1131.
