ACE Health Coach Certification Practice Test

Why would a health coach have a client perform the field test to determine the client's heart rate at VT2?

1. To determine the client's baseline level of physical fitness during phase 1

2. To program the appropriate exercise intensity for zone 2 training during phase 2

3. To program effective intervals for improving aerobic endurance during phase 3

4. To determine the client's readiness for plyometric training during phase 4

The correct answer is: To program effective intervals for improving aerobic endurance during phase 3

A health coach would have a client perform the field test to determine the client's heart rate at VT2, or the second ventilatory threshold, primarily to program effective intervals for improving aerobic endurance during phase 3. VT2 is the point at which the body transitions from predominantly aerobic energy production to anaerobic energy production. Understanding where this threshold lies for a client is essential for tailoring their training to maximize their aerobic capacity. In phase 3 training, the focus is on improving the client's aerobic endurance by incorporating interval training or steady-state sessions at or around this heart rate. Training at or near VT2 allows for optimal adaptation, enhancing both aerobic capacity and endurance performance. By knowing the client's VT2 heart rate, a coach can set specific intensities that challenge the client appropriately, leading to improvements in overall fitness levels. The other phases are linked to specific goals that do not primarily require the determination of heart rate at VT2. Phase 1 emphasizes establishing a baseline level of fitness, while phase 2 centers on programming for exercise intensities suitable for zone 2. Phase 4 is focused on more advanced training, including plyometric activities, which typically do not require knowing VT2 for readiness assessment. Therefore, identifying VT2 is most relevant in the context
