EPOC and recovery Flashcards
What is an O2 deficit
Volume of O2 required to complete an activity entirely aerobically
What is O2 debt
Temporary O2 shortage that must be repaid as a result of exercise
What does EPOC stand for
Excess post exercise O2 consumption
What are 4 reasons for fatigue
No O2 in myoglobin, ATP-PC stores depleted, high lactate levels, lactic acid
What is the role of EPOC
Continued aerobic energy production to return the body to its pre exercise state
When is O2 debt and EPOC highest
Anaerobic exercise
What are the 2 phases of EPOC
Alactacid (fast)
Lactacid (slow)
What is the alactacid component of EPOC
Fast component (10% of EPOC). Requires 1-4 litres to replenish blood and muscle O2 and resynthesize ATP/PC stores
How long does it take to restore PC stores in the alactacid component of EPOC
50% - 30 secs
100% - 3 mins
