Kinetics of anaerobic metabolism following the initiation of high-intensity exercise

摘要

A mathematical study is made of the kinetics of anaerobic metabolism following the initiation of high-intensity exercise. Power and energy relationships are proposed for oxygen-independent glycolysis, phosphocreatine utilization and the utilization of endogenous ATP. The power relations consist of two components, one describing the build-up phase, the other the controlled-utilization phase. The controlled-utilization phase of oxygen-independent glycolysis and the build-up of aerobic metabolism are shown to be closely inter-related. The theoretical relations display trends consistent with published experimental results. Some property values are derived, but because of the scatter of the experimental results, the values are, in general, to be regarded as tentative.
