Muscle fibers are termed type I (red)or type II (white).Which is a characteristic of type II fibers?
A) Slow contraction speed
B) Fast conduction velocities
C) Profuse capillary supply
D) Oxidative metabolism

Question

Quizplus · Accepted Answer

Type II fibers have fast conduction velocities, which makes them better suited for generating quick and powerful contractions. Type I fibers, on the other hand, have slower conduction velocities but are better suited for sustained, endurance-based activities due to their oxidative metabolism and profuse capillary supply.
