Peak skeletal muscle mitochondrial ATP synthesis rate (Vmax) determined from postexercise phosphocreatine recovery assessed with 31P magnetic resonance spectroscopy in healthy control (HC) subjects and patients with peripheral artery disease (PAD) under conditions of free flow (FF), reactive hyperemia (RH), FF with 100% inspired O2 (100% O2), and RH with 100% inspired O2 (RH + 100% O2) in patients with PAD. Vertical bars represent group means ± SE. *Significant difference between groups; †significant difference compared with the FF condition within group (P < 0.05).
