这项研究是在去大脑的猫的肌肉上进行的，与完整的神经和血液供应相一致，从邻近的肌肉中广泛地分离出来。用无摩擦肌电图仪研究了不同“收缩时间”哺乳动物肌肉的机械等长反应。研究发现，肌肉对不同间隔的2个刺激和不同速率的重复刺激的反应，如果测量时间间隔相对于各自的“收缩时间”，则表现出相似之处；但对于具有较短的“收缩时间”的肌肉，最大破伤风张力与抽动张力的比率通常更大。对于所有被研究的肌肉，刺激率与破伤风张力的关系遵循S曲线。
This study was made on muscles of the decerebrate cat, freed from adjacent muscles as extensively as is consistent with an intact nerve and blood supply. By means of a frictionless myograph the mechanical isometric responses of mammalian muscles with diverse "contraction times" have been investigated. It has been found that the responses of the muscles, both to 2 stimuli at various intervals and to repetitive stimuli at various rates, show similarities if the time intervals are measured relative to the respective "contraction times"; but the ratio of the maximum tetanus tension to the twitch tension is usually greater for muscles having a short "contraction time." The relation between rate of stimulation and tetanus tension follows an S-shaped curve for all the muscles studied.
