exercise? What physiological mechanisms account for these changes?
1. TMV increases during exercise, along with O2 consumption.
2. Immediately after exercise is completed, TMV remains elevated, as does O2 consumption.
3. O2 consumption & TMV remain elevated for a period of time after exercise because of oxygen debt. The reasons? (a) Lactic acid buildup in muscle produced as a result of anaerobic metabolism during exercise must be oxidized, and (b) extra O2 is needed to support the increased metabolism in exercised muscle.
