Figure 2From: Effects of dietary creatine supplementation on systemic microvascular density and reactivity in healthy young adults The peak effects of skin iontophoresis of acetylcholine (ACh) on cutaneous microvascular conductance (CVC, expressed in arbitrary perfusion units, APU, divided by mean arterial pressure in mmHg, upper panel); increases in CVC induced by iontophoresis of ACh (middle panel) and the area under the curve (AUC) of skin iontophoresis of ACh (lower panel) of healthy young subjects (n = 40) before (PRE) and after (POST) oral creatine supplementation. The amplitudes of ACh responses are expressed as peak CVC minus the baseline CVC. Values represent the means ± SEM.Back to article page
