Abstract

The kinetics of oxygen uptake () reflect the rate at which the oxidative energy supply system is adapting to the demands of a new, higher, work rate. An athlete starting a 5,000 m race requires rapid adaptation of oxidative phosphorylation to minimize the contribution of phosphocreatine and anaerobic glycolysis with lactate accumulation during the period of oxygen deficit. This will enable the athlete to maintain reserves for the sprint to the finish.  kinetics are affected by both the rate at which metabolic pathways are activated and the ability to transport O2 to the exercising muscles. Following the onset of moderate intensity exercise,  increases in a fit athlete to attain a steady state within the first two minutes. However, for higher intensities of exercise such as 5,000 m running where the metabolic demand is approaching  the attainment of a steady state is delayed. In the case of the high intensity exercise, there is a corresponding slower response of cardiac output (). Prior warm-up exercise at either moderate or heavy intensity has been shown recently to cause a more rapid increase in  which then facilitates a more rapid increase in . This review highlights some of the recent evidence concerning the kinetics of and in fit, endurance-trained, athletes during moderate and heavy intensity exercise.
