ACE Muscular Training Principles 2

Question 1

Which principle states that training adaptations are specific to the muscles, movement patterns, and energy systems used during exercise?

Accepted Answer

Specificity principle

Answer

The specificity principle (SAID — Specific Adaptation to Imposed Demands) means the body adapts precisely to the type and pattern of stress placed on it.

Question 2

A client can bench press 200 lbs for one rep. According to standard guidelines, which load best targets muscular hypertrophy?

Accepted Answer

140–160 lbs (70–80% 1RM)

Answer

Hypertrophy is optimally stimulated at 67–85% of 1RM, placing 140–160 lbs squarely in that range for a 200 lb 1RM.

Question 3

What is the primary physiological mechanism behind delayed onset muscle soreness (DOMS)?

Accepted Answer

Micro-tears and inflammatory response from eccentric muscle actions

Answer

DOMS is caused by micro-structural damage primarily from eccentric contractions, triggering an inflammatory repair process 24–72 hours after exercise.

Question 4

Which of the following best describes muscular endurance training?

Accepted Answer

2–4 sets of 12–20+ reps at <67% 1RM with short rest intervals

Answer

Muscular endurance protocols use lighter loads (≤67% 1RM), higher repetitions (≥12), and shorter rest periods to stress oxidative capacity.

Question 5

The concept of 'periodization' in resistance training primarily refers to:

Accepted Answer

Systematically varying training volume, intensity, and recovery over time

Answer

Periodization is the planned manipulation of training variables (volume, intensity, frequency) across time to optimize adaptation and prevent overtraining.
