ACSM-EP Exercise Prescription 5 — Questions and Answers
Question 1: According to ACSM, what is the recommended volume of aerobic physical activity per week that provides additional health benefits beyond the minimum?
- 300 minutes of moderate-intensity or 150 minutes of vigorous-intensity activity (Correct answer)
- 60 minutes of vigorous-intensity activity only
- 500 minutes of light-intensity activity
- 150 minutes of moderate-intensity activity
Correct answer: 300 minutes of moderate-intensity or 150 minutes of vigorous-intensity activity
ACSM and DHHS guidelines indicate that 300+ min/week of moderate or 150+ min/week of vigorous activity provides additional health and fitness benefits.
Question 2: Which ACSM principle states that the body must be stressed beyond its current capacity for training adaptations to occur?
- Overload principle (Correct answer)
- Specificity principle
- Reversibility principle
- Individuality principle
Correct answer: Overload principle
The overload principle dictates that training stress must exceed habitual levels to stimulate physiological adaptations in strength, endurance, or flexibility.
Question 3: A deconditioned client with obesity begins a walking program. After 4 weeks, they report the same walks feel easier. How should the exercise physiologist progress the program?
- Increase duration, frequency, or intensity incrementally to maintain progressive overload (Correct answer)
- Have the client reduce workout frequency to allow more recovery time
- Switch immediately to high-intensity interval training to accelerate results
- Keep the program unchanged, as perceived exertion naturally decreases over time without adjustment
Correct answer: Increase duration, frequency, or intensity incrementally to maintain progressive overload
When exercise feels easier (RPE drops), the stimulus has become sub-threshold; progressive overload must be reapplied to continue driving adaptations.
Question 4: Which cool-down strategy is MOST appropriate immediately following a high-intensity aerobic exercise session?
- 5–10 minutes of low-intensity aerobic activity followed by static stretching (Correct answer)
- Immediate cessation of activity and supine rest
- Vigorous static stretching while heart rate is still at peak
- Cold water immersion followed by immediate high-intensity resistance training
Correct answer: 5–10 minutes of low-intensity aerobic activity followed by static stretching
A gradual reduction in exercise intensity allows venous return to normalize, reduces orthostatic hypotension risk, and prepares muscles for stretching.
Question 5: For an individual with type 2 diabetes, which exercise prescription precaution is MOST important to address?
- Monitor blood glucose before, during, and after exercise to manage hypoglycemia risk (Correct answer)
- Restrict all aerobic exercise to under 10 minutes due to cardiovascular risk
- Avoid resistance training entirely to prevent blood pressure spikes
- Schedule all sessions immediately after insulin injection for best glucose control
Correct answer: Monitor blood glucose before, during, and after exercise to manage hypoglycemia risk
Blood glucose monitoring is critical for diabetic clients because exercise can cause hypoglycemia, particularly in those using insulin or sulfonylureas.
Question 6: In the context of ACSM exercise prescription, what does 'specificity' mean?
- Training adaptations are specific to the muscles used, energy systems stressed, and movement patterns trained (Correct answer)
- All clients must follow identical protocols regardless of fitness level
- Exercise intensity must always be the same for all populations
- Adaptation is non-specific and transfers equally across all fitness components
Correct answer: Training adaptations are specific to the muscles used, energy systems stressed, and movement patterns trained
The specificity principle (SAID) states that the body adapts specifically to the type, intensity, and pattern of training imposed on it.
Question 7: Which statement about rating of perceived exertion (RPE) and heart rate during exercise is most accurate?
- RPE correlates linearly with heart rate and can serve as a valid proxy for exercise intensity (Correct answer)
- RPE is unrelated to physiological measures and is purely psychological
- Heart rate always overestimates effort compared to RPE
- RPE is only valid in clinical populations, not healthy adults
Correct answer: RPE correlates linearly with heart rate and can serve as a valid proxy for exercise intensity
Research demonstrates a strong linear correlation between RPE (Borg scale) and heart rate, making RPE a practical and valid intensity monitoring tool.
