Replenish ATP and PC stores (50% in 30 secs)
Replenish blood and muscle oxygen (restaurateur haemoglobin and myoglobin)
HOW?
1-4 litres of oxygen required
Increased ventilation and circulation
Use of aerobic system for endothermic energy production

Answer 4

3 mins- 24 hours (90% of EPOC)
Replenish glycogen/ glucose stores
Remove lactic acid
60% of lactic acid is converted to Pyruvic acid
HOW?
5-8 litres of oxygen required
Increased ventilation and circulation
Increased body temp
Increased removal of lactic acid/ CO2
