Question
During the “slow” phase of the excess post-exercise oxygen consumption (EPOC) a factor contributing to increased oxygen uptake is:Group of answer choicesIncreased FFA oxidationLactate oxidationCreatine phosphate resynthesis
Solution
The "slow" phase of Excess Post-exercise Oxygen Consumption (EPOC) is characterized by the body's attempt to restore itself to its resting state. This involves several physiological processes that require oxygen, hence the increased oxygen uptake.
Among the options provided, the factor that contributes to increased oxygen uptake during the "slow" phase of EPOC is:
- Creatine phosphate resynthesis: After exercise, the body needs to replenish its stores of creatine phosphate, a molecule that provides quick energy for muscle contractions. This process requires oxygen, contributing to EPOC.
Increased FFA oxidation and lactate oxidation are also processes that occur after exercise, but they are not the primary contributors to the increased oxygen uptake during the "slow" phase of EPOC.
