Abstract
  1. The contractile properties of the motor units of the masseter and temporal muscles of human subjects were studied during voluntary isometric contractions, using a method previously employed to examine units of a small hand muscle. 2. Over the range of forces studied (0-6 kg), the units of both muscles were recruited in an orderly fashion, with a nearly linear relationship between the voluntary force at which units were recruited and their measured twitch tensions. 3. The range of contraction times (25-90 msec) was similar to that observed for the hand muscle. In some subjects it seemed that small units, recruited at low forces, exhibited shorter contraction times.
摘要
  1. 采用先前用于检测手部小肌肉运动单位的方法,对人体受试者咬肌和颞肌运动单位在随意等长收缩过程中的收缩特性进行了研究。2. 在研究的力的范围内(0 - 6千克),两块肌肉的运动单位均按有序方式募集,募集运动单位时的随意力与其测得的单收缩张力之间存在近似线性关系。3. 收缩时间范围(25 - 90毫秒)与手部肌肉观察到的范围相似。在一些受试者中,似乎在低力时募集的小运动单位表现出较短的收缩时间。
