Figure 2 Microvascular responses to acetylcholine (Ach) (top panel) and sodium nitroprusside (SNP) (bottom panel) in the fasted and postprandial states for the lean and centrally obese subjects combined in the control and exercise trials (n = 20). Statistics performed on logarithmically transformed data. *Different from fasting value in the same trial, p < 0.05 (**p < 0.01); difference between control and exercise trials at the same time point, p < 0.05.
