Question

What is the function of the ATP-CP system?

1) To provide energy all the time
2) To provide energy for low intensity long workouts
3) To provide energy for high intensity short workouts
4) all of the above

Answer 1

The ATP-CP system functions to provide energy for high-intensity, short-duration activities, such as during the initial seconds of sprinting, by rapidly supplying ATP to muscles. The correct option is 3) To provide energy for high intensity short workouts

Step-by-step explanation:

The function of the ATP-CP system, also known as the phosphagen system, is to provide energy for high-intensity short workouts. Creatine phosphate can supply the energy needs of a working muscle at a very high rate but is very limited in duration, often lasting only about 8-10 seconds.

Therefore, this system is primarily used at the beginning of muscle contraction, during high-intensity activities such as sprinting, where energy must be produced rapidly. After the ATP-CP system is exhausted, the body must rely on other systems, such as anaerobic glycolysis, for continued ATP production. The correct option is 3) To provide energy for high intensity short workouts
