ACE - Personal Trainer Cardiorespiratory Program Design Questions and Answers

Question 1

A client has progressed to the point where they can sustain 30 minutes of steady-state cardiorespiratory exercise at a moderate intensity (RPE 4 on a 0-10 scale). According to the ACE IFT Model, what is the MOST appropriate next step to enhance their aerobic efficiency?

Accepted Answer

Introduce intervals performed at an intensity at or just above the first ventilatory threshold (VT1).

Answer

The client has successfully built an aerobic base in Phase 1 of the ACE IFT Model. The next phase, Phase 2 (Aerobic-efficiency training), focuses on improving efficiency by introducing intervals at an intensity just above the first ventilatory threshold (VT1), which corresponds to an RPE of 5. This challenges the body in a new way to elicit further adaptations.

Question 2

A personal trainer is monitoring a client's workout intensity using the talk test. The client is able to speak, but can only manage a few words at a time. This level of effort is MOST closely associated with which metabolic marker?

Accepted Answer

An intensity at or near the second ventilatory threshold (VT2)

Answer

The second ventilatory threshold (VT2) is the point where lactate accumulates rapidly, and breathing becomes very heavy. At this intensity, speaking is limited to only one or two words. In contrast, at VT1, a person can still speak in short sentences, although it becomes challenging.

Question 3

For a previously sedentary client who is new to exercise, which of the following program variables should be progressed FIRST after the initial few weeks of training?

Accepted Answer

Duration

Answer

For beginner and deconditioned clients, exercise duration is the most appropriate variable to manipulate initially. This allows the musculoskeletal system to adapt gradually, minimizing the risk of overuse injury. A general guideline is to increase duration by no more than 10% per week.

Question 4

A 50-year-old client has a resting heart rate of 65 bpm. Using the Karvonen (Heart Rate Reserve) formula, what is their target heart rate range for a workout at 60-70% intensity?

Accepted Answer

128 - 139 bpm

Answer

The Karvonen formula is: Target HR = [(Max HR - Resting HR) x % Intensity] + Resting HR. First, estimate Max HR (220 - 50 = 170 bpm). Next, calculate Heart Rate Reserve (HRR) (170 - 65 = 105 bpm). Finally, calculate the range: Lower end = (105 x 0.60) + 65 = 128 bpm. Upper end = (105 x 0.70) + 65 = 138.5 bpm (rounded to 139).

Question 5

A client's primary goal is to improve their performance in short-duration, high-power events like sprinting. They are well-conditioned and have been training for years. Which phase of the ACE IFT Cardiorespiratory Training model is MOST appropriate for this client?

Accepted Answer

Phase 4: Anaerobic-power training

Answer

Phase 4, Anaerobic-power training, is designed for highly fit and competitive clients with specific performance goals that involve very high-intensity efforts for a short duration. This phase focuses on overloading the fast glycolytic system and phosphagen system to develop peak power and anaerobic capacity.
