Question

What is a PRIMARY goal of introducing interval training during phase 2 of a client's cardiorespiratory training program?

A. To help the client exercise at intensities beyond the first ventilatory threshold
B. To improve aerobic endruance by raising the intensity of exercise
C. To increase the client's adherence to the program by improving his or her mood state
D. To add variety to the program to avoid boredom

Answer 1

The main goal of introducing interval training in phase 2 of cardiorespiratory training is to improve aerobic endurance by increasing the exercise intensity, thereby enhancing overall cardiorespiratory fitness and endurance.

Step-by-step explanation:

The primary goal of introducing interval training during phase 2 of a client's cardiorespiratory training program is B. To improve aerobic endurance by raising the intensity of exercise. Interval training involves short bursts of high-intensity exercise followed by periods of lower-intensity activity or rest.

This method is effective in pushing the body beyond its first ventilatory threshold, which enhances aerobic capacity and cardiovascular efficiency. By undergoing high-intensity intervals, the client can improve oxygen utilization, muscle efficiency, and overall cardiorespiratory fitness, leading to increased endurance during aerobic activities such as running, swimming, or cycling.
