Why does the body require the three different energy systems?
|
|
It doesn’t require three different systems
|
|
|
Different sports have different demands
|
|
|
Intensity and duration of different activities and the availability of oxygen
|
|
|
Physical exercise usually takes longer than a few minutes
|
Explanation:
Detailed explanation-1: -DURATION of exercise. (How long you are exercising). E.G. If the exercise is high intensity and lasts over 2 minutes then both CP and Muscle Glycogen will become depleted and need repaying. Intensity of exercise will drop as the aerobic system becomes more dominant.
Detailed explanation-2: -Three energy systems function to replenish ATP in muscle: (1) Phosphagen, (2) Glycolytic, and (3) Mitochondrial Respiration. The three systems differ in the substrates used, products, maximal rate of ATP regeneration, capacity of ATP regeneration, and their associated contributions to fatigue.
