Chapter 6 - Fatigue and recovery mechanisms

Question 1

Define: Oxygen Deficit

Answer 1

> When oxygen supply does not equal oxygen demand.
At the start of exercise, our respiratory, circulatory and cardiovascular systems need time to adjust to the increased demand for oxygen.

Question 2

Define: Steady State

Answer 2

> Oxygen supply equals oxygen demand.

> Start working aerobically

Question 3

Define: Oxygen Debt / EPOC

Answer 3

> Excess post-exercise oxygen consumption (another name for oxygen debt)
The amount of oxygen consumed during recovery that occurs above resting levels.
O2 consumption is extended during an active recovery to aid in the removal of metabolic by-products.
The more time spent working anaerobically, the more time spent in EPOC.
Fast replenishment:
> restore PC
> takes 2-3 minutes
Slow replenishment:
> removal of metabolic by-products
> restore core temp, HR, Ventilation and other body systems to pre-exercise levels
>time depends on usage of anaerobic energy systems (accumulation of by-products).
Active recovery extends EPOC when compared to Passive recovery.
