Muscle hypertrophy

Question

Muscle hypertrophy

Quizplus · Accepted Answer

Muscle hypertrophy is an increase in muscle size due to an increase in the size of individual muscle fibers. It typically results from resistance training and an increase in protein synthesis within the muscle cells. Long periods of disuse (Option A) can actually lead to muscle atrophy or a decrease in muscle size. Endurance training (Option B) can lead to improvements in cardiovascular fitness, but it typically does not result in significant muscle hypertrophy. An increase in blood vessels to a muscle (Option D) is known as angiogenesis and can improve blood flow to the muscle, but it does not directly cause muscle hypertrophy.
