Energetics of human muscle: Exercise‐induced ATP depletion

Abstract

The energetics of human muscle have been investigated in vivo during and after fatiguing aerobic, dynamic exercise. Changes in cytoplasmic pH and concentrations of phosphocreatine, ATP and Pi were followed using 31 P nuclear magnetic resonance spectroscopy. ATP was significantly depleted in 6 out of 12 experiments and in these 6 experiments decreased to 55 ± 5% of the pre‐exercise concentration. Depleted muscle had a lower phosphocreatine concentration (17 ± 5% of resting value) and lower pH (6.12 ± 0.04) than fatigued muscle in which ATP loss was not observed (26 ± 5% for phosphocreatine and 6.37 ± 0.09 for pH). The free energy of hydrolysis of ATP was not significantly different in the two groups and was also similar in exhausted and nonexhausted muscle. Loss of ATP was associated with altered recovery of the muscle: [phosphocreatine], [Pi], and pH returned more slowly to their pre‐exercise values and the initial rate of oxidative phosphorylation was diminished. The restitution of [ATP] to its pre‐exercise value was much slower than that of the other metabolites. © 1986 Academic Press, Inc.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
