Linear relationship between systemic oxidative stress and skeletal muscle energy metabolism. (A) Systemic oxidative stress and muscle PCr loss during the plantar-flexion exercise and (B) systemic oxidative stress and IMCL content. White circles: Control subjects (n = 13). Black circles: CHF patients (n = 17). IMCL: intramyocellular lipid, PCr: phosphocreatine.
