The relative contribution of each system to ATP resynthesis is determined by the intensity and duration of the activity.
Threshold = point at which an energy system cannot provide energy.
OBLA = the point at which the concentration of lactic acid rapidly increases. (4mmol per litre of blood)
Oxygen Deficit = occurs when we cannot provide enough oxygen for the demands of the activity. Our breathing rate will increase until the demand is met.
The greater the intensity of the activity the greater the oxygen deficit. The extra oxygen taken in after exercise = EPOC (recovery process). It allows the body to return to its normal state and replenish energy stores.
Fast componant of EPOC = resaturate myoglobin to become oxymyoglobin.
Slow componant of EPOC = removal of lactic acid (converted to protein, glucose, CO2 and H20)
