Which of the following is NOT an age-related change in skeletal muscle?

A) Loss of muscle strength
B) Loss of synapse surface area
C) Loss of fast-twitch fibers
D) Decreased recovery time
E) Decrease in motor units

Fast-twitch Fibers

Muscle fibers designed for speed and power, activating quickly for short bursts of strength or speed but tiring more rapidly than slow-twitch fibers.

Muscle Strength

indicates the maximum amount of force a muscle or a group of muscles can exert against resistance in a single effort.

Synapse Surface Area

The size of the region where two neurons communicate, affecting the efficiency and strength of neural signals.
