[Purpose] The purpose of this study was to determine the activities of the muscles around the ankle joint during foot gripping. [Subjects] The subjects of this study were 17 healthy females. [Methods] We measured the maximum voluntary contraction (MVC) activities of the soleus muscle, the medial head of the gastrocnemius muscle, and the tibialis anterior muscle, and calculated %IEMG during foot gripping in 3 different ankle joint positions: 10° of plantar flexion, 0°, and 10° of dorsiflexion. [Results] The maximal force of foot gripping achived by the crural muscles in any ankle position was 30-50% IMEG of the MVC. Repeated analysis of variance showed that the %IEMG was significantly lower in 10°of dorsiflexion than in the other 2 positions for all muscles. [Conclusion] These results suggested that the crural muscles help the ankle joint by co-contracting during foot gripping.
[目的] 本研究的目的是确定足部抓握过程中踝关节周围肌肉的活动情况。[受试者] 本研究的受试者为17名健康女性。[方法] 我们测量了比目鱼肌、腓肠肌内侧头和胫骨前肌的最大自主收缩（MVC）活动，并计算了在3种不同踝关节位置（跖屈10°、0°和背屈10°）足部抓握过程中的肌电积分百分比（%IEMG）。[结果] 在任何踝关节位置，小腿肌肉实现的最大足部抓握力为MVC的30% - 50% IMEG。重复方差分析表明，对于所有肌肉，背屈10°时的%IEMG显著低于其他两个位置。[结论] 这些结果表明，小腿肌肉在足部抓握过程中通过共同收缩来辅助踝关节。
