腿部肌肉活动及其产生的力量常涉及到单关节活动情况,诸如膝关节伸展运动。某些研究中也重视到髋关节角度的影响。在多关节运动中不同肌群的功能状况已被调查,上述所有的研究均已包括了膝关节的伸展运动。不过,因研究目的和测验条件的差异尚缺乏总的结论。本研究目的在于明确2种不同运动方式(踢和跳)对膝关节伸展肌群的功能和协调性的影响。 Leg muscle activity and its resulting power often involves single-joint activities such as knee-extension exercises. Some studies also pay attention to the impact of hip angle. The functional status of different muscle groups in multi-articulation has been investigated, and all of the above studies have included knee extension. However, the general conclusion is lacking due to differences in research purposes and test conditions. The aim of this study was to determine the effect of two different exercise modes (kick and jump) on the function and coordination of the extensors in the knee joint.
