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.

Final Answer :
D
Explanation :
Decreased recovery time is not an age-related change in skeletal muscle. In fact, as people age, recovery time after muscle injury or exertion tends to increase, not decrease.
