What exercise strategy is generally used by the nervous system for muscle fiber recruitment?

Recruits fast-twitch fibers first
Recruits slow-twitch fibers first
Contracts muscles without fiber recruitment
Utilizes only Golgi tendon organs

The correct answer is: Recruits slow-twitch fibers first

The nervous system generally uses a strategy called the "size principle" for muscle fiber recruitment, which recruits the slow-twitch fibers first. Slow-twitch fibers are smaller and have a lower force output, making them more efficient for low-intensity, endurance activities. Fast-twitch fibers are only recruited when more force is needed, such as in high-intensity or power-based exercises. Contracting muscles without fiber recruitment (option C) is not possible as muscle fiber recruitment is necessary for muscle contraction. Utilizing only Golgi tendon organs (option D) is not an exercise strategy, but rather sensory receptors that respond to changes in muscle tension.
