Fig. 4
Time course of arteriolar and venular diameter changes during recovery after 1, 5, and 10 sets for each contraction protocols. Values of vessel inner diameter are normalized to each pre-contracting baseline diameter which was unchanged during the time course of the experiment. In the 0.2- and 4-ms pulse duration conditions, relative arteriolar and venular diameter changes are shown. Values are means ± SE (0.2 ms: n = 6; 4 ms: n = 8)
