Baseline and peak responses in MAP, HR, and TTI for static contraction in rats whose hindlimbs were freely perfused and in rats whose femoral artery had been ligated 72 h before the start of the experiment before and after intravenous tempol injection

		MAP, mmHg			HR, beats/min

Ligated (72 h) group
Control	6	92 ± 5	129 ± 11*	37 ± 7†	396 ± 17	424 ± 13*	27 ± 8	19.8 ± 1.7

Values are means ± SE, n, no. of rats. MAP, mean arterial pressure; HR, heart rate.

^*P < 0.05, peak vs. baseline;

^†P < 0.05, 72 h ligated vs. freely perfused.
