However, upon reexamination (Fig. 1B) these comparisons do not rule out appreciable glycolytic P i/ATP exchange. For example, Balsom and colleagues investigated the effects of creatine supplementation (20 g/d for 6-d) on PCr resynthesis rates following sprint performance.
Journal of Applied Physiology. We hypothesized that middle-aged persons would have lower resting muscle PCr concentrations and slower PCr resynthesis rates. Characteristics of the Various Energy Supply Systems: ATP-PCr. Oxygen: no Chem reaction: PCr to Cr Rate of ATP formed per second: 10 ATP formed per molecule: 1.
