Figure 1. CCRCs to methylcholine in mesenteric arteries from male and female, control and IUGR, sedentary and exercised offspring.

Percentage vasodilatation to methylcoline (MCh) in mesenteric arteries from males (A; n = 8–13) and females (B; n = 8–13). Groups include: control sedentary offspring (continuous lines, filled squares), control exercised offspring (dashed lines, open squares), IUGR sedentary offspring (continuous lines, filled triangles), and IUGR exercised offspring (dashed lines, open triangles). Data are presented as mean ± SEM and summarized as pEC₅₀ in the inset bar graph figures: sedentary offspring (filled bars) and exercised offspring (hatched bars). *P < 0.05 for a statistically significant interaction between aerobic exercise training and IUGR in male offspring.
