Sarcomere movements during isometric tetanic contractions were resolved to 50 angstroms by diffraction techniques. After a latent period that followed the first stimulus, all sarcomeres shortened simultaneously and uniformly. Oscillations in length and tension in synchrony with the stimuli occurred during an incomplete tetanus. However, no oscillations in length were detected during the plateau of a tetanus.
在等长强直收缩期间，肌节运动通过衍射技术解析到50埃的精度。在第一个刺激后的潜伏期过后，所有肌节同时且均匀地缩短。在不完全强直收缩期间，长度和张力会与刺激同步振荡。然而，在强直收缩的平台期未检测到长度振荡。
