ACE Health Coach Certification Practice Test

A client can perform 30 minutes of cardiorespiratory exercise just below the talk test threshold. What is the most appropriate progression for her?

1. Increase exercise duration to 45 minutes

2. Introduce three intervals just above the second ventilator threshold

3. Short intervals above the first ventilator threshold

4. Increase intensity by adding weights

The correct answer is: Short intervals above the first ventilator threshold

The rationale for choosing short intervals above the first ventilator threshold as the most appropriate progression hinges on the client’s current ability to exercise and the principles of exercise progression. Since the client can comfortably perform 30 minutes of cardiorespiratory exercise just below the talk test threshold, she demonstrates a solid foundational level of aerobic fitness. Incorporating short intervals above the first ventilator threshold allows for an increase in intensity without overwhelming the client. This approach enhances cardiorespiratory fitness by briefly challenging her cardiovascular system while still promoting safety and adherence to her exercise regimen. It also encourages the development of both aerobic and anaerobic energy systems, leading to improved endurance and overall performance over time. This method of progression is particularly effective for clients who are at an intermediate level of fitness, as it encourages adaptation and avoids plateauing in their training. The focus on intervals keeps the workouts interesting and can help motivate the client to push her limits in a controlled manner. Other options, such as increasing the duration to 45 minutes or introducing longer intervals above the second ventilator threshold, may not be the best fit based on the client’s current capability. Increasing intensity by adding weights could also detract from her primary goal of improving cardiorespiratory fitness at this
