Document Summary
Can be seen as the region in which o2 consumption plateaus or increases only slightly with additional increases in exercise intensity. Provides a quantitative measure of capacity for aerobic atp resynthesis. Performing more intense exercise will require glycolysis and will reinst in lactate accumulation. More intense exercise produces a greater post exercise oxygen consumption than oxygen deficit alone would suggest. Consists of a fast and slow component. This excess postexercise oxygen consumption (epoc) is not simply due to removal of lactate, as well as traditionally thought. It has been demonstrated that most lactate is oxidized for energy, leading to contemporary concepts. Level of anaerobic metabolism in just completed exercise bout. Optimal recovery depends upon type of exercise. Use passive recovery- extra activity would only serve to elevate total metabolism and delay recovery. Working ~ 30-45% if cycling to recover. Tell us what fuel is being used during rest and steady state aerobic exercise.
