The silent period in the agonist prior to rapid voluntary movement (premotion silent period) was observed in the lower limb muscles. The subject was asked to respond to the flashing light by performing a vertical jump as quickly as possible. The most consistent results were obtained in the extensors, particularly the quadriceps. The frequency of the silence of six subjects was 53% in the rectus femoris, 61% in the vastus medialis, and 72% in the vastus lateralis. A neural switching mechanism, directing excitation from preparation phase of jumping into rapid contraction phase, seemed to be attributable to the occurrence of the premotion silent period.
在下肢肌肉中观察到了快速自主运动之前激动剂的静息期(运动前静息期)。受试者被要求通过尽快进行垂直跳跃来对闪烁光做出反应。在伸肌,尤其是股四头肌中获得了最一致的结果。六名受试者的静息频率在股直肌中为53%,在内侧股四头肌中为61%,在外侧股四头肌中为72%。一种将兴奋从跳跃准备阶段引导至快速收缩阶段的神经转换机制似乎是运动前静息期出现的原因。
