Rats were fed a diet containing 1% beta-guanidino-propionic acid (GPA) for 6-12 wk to deplete their muscles of phosphocreatine (PCr). Gated 31P nuclear magnetic resonance (NMR) spectra were obtained from the gastrocnemius-plantaris muscle at various time points during either a 1- or 3-s isometric tetanic contraction using a surface coil. The energy cost of a 1-s tetanus in unfatigued control rat muscle was 48.4 mumol ATP X g dry wt-1 X s-1 and was largely supplied by PCr; anaerobic… CONTINUE READING
