A potential benefit of recruiting slow oxidative fibers for contraction before recruiting fast oxidative and fast glycolytic fibers might be ________.
A) because they are slower to respond, slow oxidative fibers must be stimulated first in order to contract simultaneously with the faster fibers
B) there is little to no benefit from recruiting slow oxidative fibers first and therefore it is in fact fast glycolytic fibers that will be recruited first
C) recruiting slow oxidative fibers early helps to tire them out first so that they won't interfere with the more powerful contractions of fast glycolytic fibers
D) this will help to allow for fine control with delicate contractile force with a small stimulus

Question

Quizplus · Accepted Answer

Recruiting slow oxidative fibers first allows for fine control and delicate contractile force with a small stimulus. Slow oxidative fibers have a lower threshold for activation and can sustain contractions for longer periods of time, making them ideal for activities that require low levels of force and endurance. By using these fibers first, the body can perform fine motor tasks before recruiting the more powerful, but less endurance-oriented fast glycolytic fibers.
