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.
