If a sport relies on the aerobic lipolysis system, what is the rate?

Explanation:
The rate of energy production from aerobic lipolysis is very slow because fat metabolism involves many steps and relies on abundant oxygen. Triglycerides must be broken down (lipolysis) to free fatty acids, transported into mitochondria, then undergo beta-oxidation, followed by the Krebs cycle and the electron transport chain to make ATP. Each step takes time, so even though fat provides a large amount of energy per molecule, the overall rate of ATP production is slow. This makes aerobic lipolysis ideal for long-lasting, steady efforts, rather than quick, high-intensity bursts.
