Mean arterial pressure (expressed in mmHg) pre- and postsuperfusion of Krebs-Henseleit (control), SNP, and l-NAME in sedentary and exercise-trained rats

	Control		SNP		l-NAME
	Pre	Post	Pre	Post	Pre	Post
Sedentary	123 ± 4	124 ± 4	125 ± 5	111 ± 4*	128 ± 4	132 ± 5
Trained	132 ± 3	133 ± 4	134 ± 5	95 ± 6*†	134 ± 4	137 ± 4

Values are means ± SE. Results are presented from animals under the following conditions: sedentary control (n = 18), sedentary sodium nitroprusside (SNP) (n = 14), sedentary N^G-nitro-l-arginine methyl ester (l-NAME) (n = 14), trained control (n = 10), trained SNP (n = 9), and trained l-NAME (n = 10). Significantly different from:

^*all other conditions within group;

^†sedentary post-SNP superfusion.
