Question

Quizplus · Accepted Answer

Activities with a performance time of approximately 30 seconds or less rely on the immediate energy system, which is the ATP-PCr system. This system uses the stored phosphocreatine (PCr) and ATP in the muscles to provide energy for short bursts of high-intensity activity. The other energy systems, such as aerobic glycolysis, rely on oxygen and take longer to produce ATP, making them less suitable for short-duration, high-intensity activities.
