Forearm blood flow increased with exercise (Main effect of exercise, p<0.01). Blood flow was not altered by sildenafil citrate (Main effect of SDF, p=0.81). L-NMMA resulted in a reduction in blood flow alone (Main effect of L-NMMA, p<0.01) and when combined with sildenafil citrate (Main effect of SDF+L-NMMA, p=0.04). *p<0.05 vs Rest, †p<0.05 vs Control.
