ACE Muscular Training Principles 3

Question 1

Which muscle fiber type is most recruited during a 400-meter sprint?

Accepted Answer

Type IIx (fast-twitch glycolytic)

Answer

A 400-meter sprint relies heavily on Type IIx fast-twitch fibers due to high-speed, high-force demands that quickly deplete phosphocreatine and utilize anaerobic glycolysis.

Question 2

According to the ACE IFT Model, which component of a resistance training program should be established first for a beginner?

Accepted Answer

Neuromuscular efficiency and movement quality

Answer

The ACE IFT Model prioritizes establishing a base of neuromuscular efficiency, joint stability, and correct movement patterns before progressing to load-focused phases.

Question 3

What does the term 'training volume' represent in resistance training?

Accepted Answer

Sets × reps × load across a given training period

Answer

Training volume is quantified as the product of sets, repetitions, and load (sets × reps × weight), representing total mechanical work performed.

Question 4

A client wants to improve muscular power for a sport that requires explosive jumps. Which training method is MOST appropriate?

Accepted Answer

Olympic lifts and plyometrics at 30–70% 1RM with maximal velocity

Answer

Power training requires moving loads at high velocity; Olympic lifts and plyometrics at 30–70% 1RM develop the rate of force development needed for explosive sport movements.

Question 5

Which of the following is an example of a bilateral strength deficit?

Accepted Answer

Being stronger during a single-leg squat than during a bilateral back squat on a per-leg basis

Answer

A bilateral deficit occurs when each limb produces less force when both are working simultaneously than when working independently, suggesting inhibition during bilateral efforts.
