Figure 5. Left panels, Absolute values of mean arterial pressure (MAP, A) and heart rate (HR, B) at rest and during graded exercise (black bar) of sedentary (S) and trained (T) normotensive (WKY) and spontaneously hypertensive (SHR) rats. Right panels, Changes in relative hind limb flow (HLF rel, C) and relative hind limb resistance (HLR rel, D) during graded exercise (black bar) in sedentary (S) and trained (T) WKY and SHR. Exercise intensities are 0.4, 0.8, 1.1, and 1.4 km/h, 2 min each. Six to 12 rats/group. *P < 0.05 vs WKY; P < 0.05 vs S (two-factor ANOVA). Adapted from Ref. 23, with permission.
