Question

Between the ATP-PCr System, the glycolytic sytem, and the oxidative system.

1. Which one has the most rate of energy production? Which one has the least?

2. Rank them based on their capacity

Answer 1

Conventionally, there are three energy systems that produce ATP: ATP-PC (high power, short duration), glycolytic (moderate power/short duration), and oxidative (low power/long duration).

ATP must be present for muscles to contract. It can be produced via the ATP-PC system, the glycolytic system, or the oxidative system.

1. ATP-PC has the most rate of production of energy production. (~36 calorie/min.) - High power/Short duration Eg. Short sprint

Oxidative system has the least energy production. (~10 calorie/min.) - Low power/Long duration Eg. 10 mile run-

2. Ranking of energy production rate:

1. ATP-PC (36 calorie/min.)
2. Glycolysis (16 calorie/min.)
3. Oxidative sysytem (10 calorie/min.)
