n = 9. FBF: forearm blood flow, LBM: lean body mass, MAP: mean arterial pressure, FVC: forearm vascular conductance, HR: heart rate, $S_{{\text{aO}}_2}$: arterial oxygen saturation, $C_{{\text{aO}}_2}$: arterial oxygen content, $C_{{\text{vO}}_2}$: forearm venous oxygen content, a–vO_2diff: arteriovenous oxygen difference, $\text{m}{\dot{V}}_{{\text{O}}_2}$: forearm muscle oxygen consumption. Data are means ± SEM.
