Figure 4.
Skeletal muscle energetic parameters (PCr, Pi, pH, ADP, ΔG~ATP) and phosphodiester (PDE) during baseline resting conditions (A–F, left column) and at the point of fatigue (G–K, right column). There are no significant differences in the SM energetic parameters among the four groups at rest or at the point of fatigue (although PDE differed at baseline). Comparisons vs healthy subjects, § p<0.005, §§§ p<0.001.
