Abstract
Tension changes caused by slow stretch or release of actively contracting muscle are accompanied by axial displacements of myosin heads (i.e., cross-bridges) from the positions characteristic of isometric contraction. The direction of the axial displacement appears to affect the rate of cross-bridge detachment or reattachment during muscle-length changes.
摘要
主动收缩肌肉缓慢拉伸或放松所引起的张力变化，伴随着肌球蛋白头部（即横桥）从等长收缩特征位置的轴向位移。轴向位移的方向似乎会影响肌肉长度变化过程中横桥解离或重新附着的速率。
