许多锻炼都是用来增强膝关节肌肉的，但是评估这些锻炼的研究有限。本研究的目的是描述和比较五种康复训练中五块膝盖肌肉的肌肉放电模式，这些训练被认为是为了加强特定的肌肉群或引起收缩。在短弧度膝关节伸展时，内侧和外侧股肌在最后15度伸展时比其他弧度伸展时明显更活跃（p < 0.05）。短弧膝关节伸展伴腘绳肌收缩，在最后15度伸展时，股直肌、股斜内侧肌和股外侧肌的活动明显高于股二头肌和半膜肌（p < 0.05）。在等距膝盖收缩时，肌肉活动在任何弧度测试中都没有显著差异。在深蹲时，股直肌、股斜内侧肌和股外侧肌在下降、保持和上升阶段明显比股二头肌和半膜肌活跃（p < 0.05）。这些信息为选择最佳的膝关节康复运动提供了建议。
Many exercises are used to strengthen the knee muscles, yet limited studies that evaluate the exercises exist. The purpose of this study was to describe and compare the muscle firing patterns in five knee muscles during five rehabilitative exercises, which were presumed either to strengthen a specific muscle group or to elicit a cocontraction. During short-arc knee extension, the medial and lateral vasti were significantly more active during the last 15-degrees of extension than during other arcs (p < .05). The short-arc knee extension with hamstring cocontraction demonstrated significantly more activity in the rectus femoris, vastus medialis oblique, and vastus lateralis than the biceps femoris and semimembranosus in the final 15-degrees of extension (p < .05). With isometric knee cocontractions, no significant difference in muscle activity occurred in any of the arcs tested. During squatting, the rectus femoris, vastus medialis oblique, and vastus lateralis were significantly more active than the biceps femoris and semimembranosus during the descending, holding, and arising phases (p < .05). This information offers suggestions in selecting optimal knee rehabilitation exercises.
