Bundles of glycerol-extracted psoas fibres which were contracted by immersion in a saline containing 15 mM MgATP and 12 micron free Ca++ were subjected to up to 3 stretches (rise time 0.8 msec) each of amplitude 1% Li at intervals of 10 msec. The elastic tension responses to these stretches were all of comparable size and the peak tensions reached during the stretches were in each case followed by a rapid tension decline almost to the tension values before the stretches. This indicates that stretch-induced detachment and reattachment of cross bridges to the actin filament occurred within 10 msec (slippage).
将浸于含有15 mM 镁三磷酸腺苷（MgATP）和12微摩尔游离钙离子（Ca++）的盐溶液中而收缩的甘油抽提腰大肌纤维束，每隔10毫秒进行高达3次的拉伸（上升时间0.8毫秒），每次拉伸幅度为1%的长度变化（Li）。对这些拉伸的弹性张力反应大小都相当，并且在每次拉伸过程中达到的峰值张力之后，紧接着是张力迅速下降，几乎降至拉伸前的张力值。这表明，在10毫秒内发生了拉伸诱导的横桥与肌动蛋白丝的分离和重新附着（滑动）。
