    Endothelial Function

    (A) Average peak velocity and brachial diameter during the control (no exercise), continuous moderate-intensity exercise (CME), high-intensity aerobic interval exercise (HIIE), and sublingual glycerol trinitrate (NTG) trials. Baseline-1 is measured before the intervention, baseline-2 16 to 18 h after intervention and immediately before the meal. Thereafter, flow-mediated dilation (FMD)/artery diameter and blood flow were measured 30 min, 2 h, and 4 h after food intake. (B) FMD of the brachial artery during the experiment. (C) FMD normalized for share rate. #Different from baseline-1, p < 0.01; *different from moderate and control, p < 0.01; **different from moderate and control, p < 0.001; §different from control, p < 0.01; £different from baseline, p < 0.05.
