Question

Which characteristic is true of type ii (white fast-motor) muscle fibers? slow contraction speed fast conduction velocities profuse capillary supply oxidative metabolism?

Answer 1

Answer;

Fast conduction velocities

Step-by-step explanation;

-There are two general types of skeletal muscle fibers: slow-twitch (type I) and fast-twitch (type II). Slow-twitch muscles help enable long-endurance feats such as distance running, while fast-twitch muscles fatigue faster but are used in powerful bursts of movements like sprinting.

-Type I muscle fibers are more efficient over long periods of time. They are mainly used for postural maintenance (such has holding the head upright), or endurance exercises (like marathon running).

-Type II muscle fibers on the other hand use anaerobic respiration and are better for short bursts of speed than Type I fibers, although they fatigue more quickly.
