Abstract
Pulse-propagation measurements on a muscle stimulated into tetanus show that the stiffness develops earlier and starts later than the tension. It is concluded that the myosin heads which moves towards the actin filaments during excitation become mechanically attached to them.
摘要
对处于强直收缩状态的肌肉进行脉冲传播测量表明，僵硬度比张力更早出现且开始时间更晚。得出的结论是，在兴奋过程中朝着肌动蛋白丝移动的肌球蛋白头部会在机械上附着于它们。
