Previous work has relied on muscle biopsy of exercising subjects at different times in different exercise bouts. Chemical evaluation of metabolites has been hampered by continuing change in metabolic concentration during the biopsy procedure. Recently, Fourier-transformed 31P nuclear magnetic resonance (31P-NMR), employing surface coils, has made evaluation of phosphorus metabolites possible by noninvasive atraumatic means in human muscle. Relative concentrations of PCr, Pi, and ATP, together with pH, have been obtained with 31P-NMR from the flexor digitorum superficialis muscle on two occasions in four adult men during the transition from rest to exercise. (PCr) rapidly fell and was mirrored by a rise in (Pi). The former temporarily exceeded the latter with the discrepancy apparently being absorbed by a transient rise in (ATP), which was itself mirrored by alteration in (H+).
