Question | Answer |
---|---|
What does EPOC stand for? | Excess post-exercise oxygen consumption |
What are the two compnents | Fast component and Slow component |
What is the fast component? | oxygen used for rapid resynthesis of phosphocreatine and resaturation of myoglobin |
What is the slow component? | oxygen used to remove lactic acid and maintain high heart rate, breathing rate and body temperature |
What causes EPOC of the same performer to vary? | Intensity and Duration |
What are the functions of the fast component? | Restoration of ATP Resaturation of myglobin with oxygen |
How are functions of slow component achieved? | Removal of lactic acid by oxidation in other organs/ Conversion to pyruvate acid used as energy source to water and CO2 |
What is steady state? | The period of exercise when oxygen consumption matches the energy being used |
What is aerobic capacity? | the maximum rate at which a person can consume oxygen |
What are the functions of the slow component? | Removal of lactate/ supply breathing muscles/ supply heart heart muscles |
