The activation of antagonistic muscles is studied during isometric combined contractions of bifunctional muscles. It is established that the co-contraction mechanism observed in such situations limits unwanted movements. Furthermore, when a co-contraction appears between two biantagonistic muscles, the phenomenon underlies a conflicting situation and, consequently, the muscular patterns encountered are in most cases the reverse of those classically described. In these circumstances the inhibition usually present between antagonistic muscles could be masked, due to convergence on the motoneurones of both inhibitory and excitatory discharges coming from homonymous and antagonistic muscles of a given bifunctional muscle.
在双功能肌肉的等长联合收缩过程中，对拮抗肌的激活进行了研究。已确定在这种情况下观察到的共同收缩机制限制了不必要的运动。此外，当两块双拮抗肌之间出现共同收缩时，这种现象构成了一种冲突情况，因此，在大多数情况下遇到的肌肉模式与经典描述的相反。在这些情况下，由于来自给定双功能肌肉的同名肌和拮抗肌的抑制性和兴奋性放电在运动神经元上汇聚，拮抗肌之间通常存在的抑制可能会被掩盖。
