The purpose of this study was to evaluate intramuscular pH and the high energy phosphate metabolism in the skeletal muscle between athletes (n=11) and sedentary men (n=11). Exercise protocols were consisted of continuous isometric contractions of Maximal Voluntary Contraction (MVC) 1% and MVC 5%. ³¹P NMR spectroscopy was used for analyzing intramuscular pH and Pi/PCr during exercise. In both groups, intramuscular pH was decreased according to the time course. The lowest intramuscular pH in athletes was observed at 28 min after MVC 1% exercise, which was significantly higher than that of sedentary men (p<.05), and the reduction rate of pH was about 2.6%. The same results were obtained with MVC 5% exercise. The ratio of Pi to PCr (Pi/PCr) was increased according to the time course in both groups. The highest ratio of Pi/PCr in athletes was observed at 24 min with MVC 1% exercise, which was significantly lower than that of sedentary men (p<.05). The ratio of Pi/PCr at all-out with MVC 5% exercise was lower than that of resting, which was different from sedentary men. In conclusion, intramuscular pH muscle in athletes was significantly higher and the ratio of Pi/PCr in athletes was significantly lower, than those of sedentary men (p<.05).
