Phosphorus nuclear magnetic resonance (NMR) spectra and twitch tension were recorded during stimulation of gastrocnemius muscles of pentobarbital sodium-anesthetized rats which had been fed the creatine analogue beta-guanidinopropionic acid (beta-GPA, 2% diet) for periods from 0 (control) to 8 wk. Total creatine content of unstimulated muscles decreased by… (More)
