This study attempted to develop a formula for predicting maximum muscle strength value for young, middle-aged, and elderly adults using theoretical Grade 3 muscle strength value (moment fair: )-the static muscular moment to support a limb segment against gravity-from the manual muscle test by Daniels et al. A total of 130 healthy Japanese individuals divided by age group performed isometric muscle contractions at maximum effort for various movements of hip joint flexion and extension and knee joint flexion and extension, and the accompanying resisting force was measured and maximum muscle strength value (moment max, ) was calculated. Body weight and limb segment length (thigh and lower leg length) were measured, and was calculated using anthropometric measures and theoretical calculation. There was a linear correlation between and in each of the four movement types in all groups, excepting knee flexion in elderly. However, the formula for predicting maximum muscle strength was not sufficiently compatible in middle-aged and elderly adults, suggesting that the formula obtained in this study is applicable in young adults only.
本研究试图利用丹尼尔斯等人的手法肌力测试中理论上的3级肌力值（力矩尚可： ）——支撑肢体节段对抗重力的静态肌肉力矩，开发一种用于预测年轻人、中年人和老年人最大肌肉力量值的公式。总共130名按年龄分组的健康日本个体，针对髋关节屈伸和膝关节屈伸的各种动作进行了最大努力的等长肌肉收缩，并测量了伴随的阻力，计算出最大肌肉力量值（力矩最大值， ）。测量了体重和肢体节段长度（大腿和小腿长度），并使用人体测量学方法和理论计算得出 。除老年人膝关节屈曲外，所有组的四种运动类型中， 与 之间均存在线性相关性。然而，预测最大肌肉力量的公式在中年人和老年人中兼容性不足，表明本研究中获得的公式仅适用于年轻人。
