1.心血管反应的持续收缩张力从5至30%的最大随意收缩（MVC）进行了检查。在5和10%MVC时，血压、心率和前臂血流在收缩期间均达到稳定状态;运动后充血并未显示出高于运动期间的峰值血流。在20%和30% MVC的张力下，收缩期间没有任何测量结果显示稳定状态，但在整个收缩期间稳定增加;运动后充血特征性地显示峰值流量超过收缩期间测量的任何流量。在15%MVC张力下获得的结果在收缩期间未显示稳态，但随后的充血显示出与较低张力下观察到的模式相似。
1. The cardiovascular responses to sustained contractions at tensions from 5 to 30% maximal voluntary contraction (MVC) have been examined. At 5 and 10% MVC blood pressure, heart rate and forearm blood flow all reached a steady state during the contraction; post‐exercise hyperaemia did not show peak flows higher than those found during exercise. At tensions of 20 and 30% MVC, none of the measurements showed a steady state during the contractions, but increased steadily throughout the contraction; post‐exercise hyperaemia characteristically showed peak flows in excess of any flow measured during contractions. The results obtained at a tension of 15% MVC did not show a steady‐state during the contraction but the following hyperaemia showed a similar pattern to that seen at the lower tensions.
