The effect of nerve blocking on the blood flow through the skeletal muscle during and after contraction was examined. Muscle blood flow was measured by heated thermocouple technique on the rabbit quadriceps muscle stimulated by tetanic currents of various strengths and lengths of time. Femoral nerve division in weak and prolonged contraction and also epidural anesthesia in weak and brief contraction resulted in a significant decrease in peak flow through the muscle. In strong contraction, however, blocking the sympathetic nerve did not affect the blood flow during contraction. This results suggest that the main mechanism producing the hyperemia during contraction is not dependent on the sympathetic nervous system but at least in some part autonomic nervous system may play a role in the dilator reaction.
研究了神经阻滞对收缩期间及收缩后骨骼肌血流的影响。采用热偶技术，通过不同强度和时长的强直电流刺激兔股四头肌，测量肌肉血流量。在弱而持久的收缩中进行股神经切断，以及在弱而短暂的收缩中进行硬膜外麻醉，均导致肌肉峰值血流显著降低。然而，在强收缩时，阻断交感神经并不影响收缩期间的血流。这些结果表明，收缩期间产生充血的主要机制不依赖于交感神经系统，但自主神经系统至少在某种程度上可能在扩张反应中发挥作用。
