A potential benefit of recruiting slow oxidative fibers for contraction before recruiting fast oxidative and fast glycolytic fibers might be __________.
A) to allow for fine control with delicate contractile force with a small stimulus
B) 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
C) because they are slower to respond, slow oxidative fibers must be stimulated first in order to contract simultaneously with the faster fibers
D) 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.

Slow oxidative fibers have a high resistance to fatigue and are recruited first to provide a sustained, low-level force for activities such as posture and maintaining balance. By recruiting these fibers first, the muscle can have fine control with delicate contractile force using a small stimulus. This is beneficial for activities that require precise movements or low-level force control.
