31P NMR studies of resting muscle in normal human subjects
Abstract
Study of human tissues using 31P topical Magnetic Resonance is completely atraumatic; it allows simultaneous measurement of the concentrations of many important metabolites and of intracellular pH. In some critical situations, TMR yields more accurate results than those obtained by chemical analysis of tissue biopsies. We have shown that TMR can be calibrated to obtain quantitative measurements in human subjects. We have also shown that theories of control of glycolysis based on regulation by key metabolites of rate-limiting enzymes are inconsistent with the observed changes in intact muscle.
