Fig. 2.

A: femoral artery ligation increased the responses of thin-fiber (i.e., group III plus group IV) afferents to static contraction. B: separately, the responses of group III afferents to static contraction were significantly greater in ligated rats than those in freely perfused rats. C: likewise, the responses of group IV afferents to static contraction were significantly greater in ligated rats than those in freely perfused rats. Values are means ± SE; n, no. of rats. *Contraction value was significantly greater than its corresponding baseline value, P < 0.05. #Difference in afferent activity from baseline to contraction was greater in the ligated rats than it was in the freely perfused rats. The tension-time indexes for the freely perfused and ligated conditions were not significantly different.
