摘要

测量了10名不同髋关节和膝关节角度组合的健康受试者的最大等长伸肌力量。使用普通的锻炼设备进行测量,该方法可用于临床工作。结果表明,膝关节角度不影响髋关节伸肌的力量。伸肌最大力矩出现在髋关节屈曲90度时,随着髋关节角度的减小而减小。男性和女性在运动领域的力量分布不同。研究发现,当受试者处于俯卧姿势时,在髋关节角度为60度-0度时,身体节段的重量利用了最大力量的10-24%。

Influence of knee flexion on isometric hip extensor strength.
The maximum isometric extensor muscle strength was measured in 10 healthy subjects of different combinations of hip and knee angles. An ordinary exercise device was used for the measurements and the method could be useful in clinical work. The results revealed that the knee angle does not affect the hip extensor strength. The highest extensor muscular moments occurred at 90 degrees hip flexion, decreasing with decreasing hip angle. The distribution of the strength over the motion sector differed between male and female. The weight of the body segments was found to utilize 10-24% of the maximum strength at hip angles 60 degrees-0 degrees with subjects in a prone position.
