Which phase of cardiorespiratory training incorporates the VT2 threshold test to help clients with endurance performance goals?

1. Aerobic-base training

2. Aerobic-efficiency training

3. Anaerobic-endurance training

4. Anaerobic-power training

The correct answer is: Anaerobic-endurance training

The phase of cardiorespiratory training that incorporates the VT2 threshold test is anaerobic-endurance training. This phase focuses on improving a client's performance in high-intensity efforts that exceed their anaerobic threshold, which is critical for endurance athletes or those pursuing endurance performance goals. The VT2 threshold test assesses the point at which lactate begins to accumulate in the blood, indicating a shift from predominantly aerobic metabolism to anaerobic metabolism. By identifying this threshold, trainers can tailor workouts that enhance endurance capabilities just above this critical point, helping clients maintain performance during prolonged duration activities. In this context, developing anaerobic endurance allows clients to sustain higher levels of intensity longer, making it an essential component for their training regimen. The other phases—such as aerobic-base and aerobic-efficiency training—primarily target building foundational fitness and efficiency at lower intensities, which do not require the same focus on the anaerobic threshold. Anaerobic-power training, while also intensity-focused, differs as it emphasizes short bursts of maximum effort rather than extended endurance.
