Question

A client who is in phase 3 of the cardiorespiratory training component of the ACE IFT Model is beginning to utilize the three-zone training model based on ventilatory threshold. Approximately what % of his time should be spent between VT1 and VT2?

A. 70-80%
B. < 10%
C. 10-20%
D. > 80%

Answer 1

A client in phase 3 of the cardiorespiratory training component should spend approximately 70-80% of their time between VT1 and VT2, which represents the aerobic zone.

Step-by-step explanation:

In the ACE IFT Model, phase 3 of the cardiorespiratory training component focuses on utilizing the three-zone training model based on ventilatory threshold. The three zones are VT1 (the aerobic zone), VT2 (the anaerobic threshold), and VT3 (the anaerobic zone).

For a client in phase 3, the majority of their time should be spent between VT1 and VT2. This represents the aerobic zone, which is approximately 70-80% of their maximum heart rate. Spending time in this zone helps improve cardiovascular fitness and endurance.

Therefore, the correct answer is A. 70-80%.
