ACE Personal Trainer Practice Exam

For a single effort, what is the recommended number of repetitions per set for muscular power?

1. 1-2 reps

2. 3-5 reps

3. 6-8 reps

4. 8-10 reps

The correct answer is: 1-2 reps

For developing muscular power in a single effort, the recommended number of repetitions per set is typically between 1 to 2 reps. This low-repetition approach allows for the use of heavier loads or explosive movements, which are critical for maximizing power output. When training for power, the emphasis is on the quality and intensity of each movement rather than the quantity, which is why fewer repetitions are favored. Training in this rep range helps to enhance the neuromuscular system's ability to recruit muscle fibers quickly and effectively, which is essential for producing high levels of force in a short amount of time. This method aligns with the goals of power training, making it ideal for athletes who need to perform explosive actions, such as in sports that require sprinting, jumping, or quick changes in direction. In contrast, higher repetition ranges, such as those found in strength or hypertrophy training, would not provide the same benefits for developing pure power, as they involve lighter loads and a greater focus on endurance and muscle size rather than explosive strength.
