Representative 31phosphorus-magnetic resonance spectra at rest (upper panel) and peak plantar flexion exercise (lower panel) in the calf muscle of a control subject (a) and a MetS patient (b). The summary data of standardized PCr at rest (c), peak exercise (d) and PCr loss (e) from control subjects (n=11) and MetS patients (n=12). *P<0.05 and †P<0.01 vs. control subjects. MetS, metabolic syndrome; PCr, phosphocreatine; Pi, inorganic phosphate.
