[目的]本研究的目的是通过将手持测力计和腰带测量的下肢和臀部等长肌肉力量测量值与等速测力计测量值进行比较，评估其有效性。 [研究对象] 研究对象为24名健康成年人（12名男性，12名女性），平均年龄20.4岁。 [方法]用两台仪器分别测量髋部的屈肌、伸肌、外展肌、内收肌、外旋肌、内旋肌以及膝关节的屈伸肌。 [结果] 手持式测功机和腰带所获得的测量值明显低于等速测功机所获得的测量值。对于所有肌肉群，使用这两种仪器进行的测量，皮尔逊相关系数在 0.52 到 0.88 之间，但髋关节外展肌除外，相关系数为 0.34。在髋关节外展肌中，排除 450 N 及以上的力时，系数为 0.65。 [结论] 除了高肌力受试者的髋部外展测量外，手持式测力计和腰带获得的下肢和臀部等长肌力测量被认为是有效的。
[Purpose] The aim of this study was to evaluate the validity of isometric muscle strength measurements of the lower limbs and hips made with a hand-held dynamometer and belt by comparing them with measurements obtained by an isokinetic dynamometer. [Subjects] The subjects were 24 healthy adults (12 men, 12 women) with a mean age of 20.4 years. [Method] Measurements were made with both instruments on the flexors, extensors, abductors, adductors, external rotators and internal rotators of the hip and flexors and extensors of the knee. [Results] Measurements obtained with the hand-held dynamometer and belt were significantly lower than those obtained with the isokinetic dynamometer. Pearson's correlation coefficients for the measurements made with the two instruments ranged from 0.52 to 0.88 for all muscle groups except the hip abductors which was 0.34. In the hip abductors, the coefficient was 0.65 when forces of 450 N and higher were excluded. [Conclusion] Isometric muscle strength measurements of the lower limbs and hips obtained with a hand-held dynamometer and belt are considered to be valid except for measurement of hip abduction of subjects with high muscle strength.
