Muscle Hypertrophy

Question

Muscle hypertrophy
A) results from long periods of disuse
B) results from endurance training
C) is an increase in muscle size
D) results from an increase in blood vessels to a muscle

Accepted Answer

Muscle hypertrophy occurs when there is an increase in the size of the muscle fibers due to an increase in protein synthesis. This typically occurs when the muscles are subjected to resistance training and is a sign of increased muscle strength. It is not caused by long periods of disuse or an increase in blood vessels to the muscle. While endurance training can lead to improved endurance and fitness, it is not typically associated with significant muscle hypertrophy.
