Exercise 5

List the optimal frequency, intensity, and duration of exercise needed to achieve an increase in cardiorespiratory function.

Step 1 of 4

The effect of exercise on cardiorespiratory function (CRF) depends on the frequency, duration, and intensity of the exercise sessions. The volume of exercise is the product of frequency, intensity, and time duration of the exercise. However, to increase CRF, relative intensity is mainly focused to structure the exercise program.
