Muscle hypertrophy in humans is primarily due to what?

Question

Quizplus · Accepted Answer

Muscle hypertrophy in humans is primarily due to an increase in the size of muscle fibers rather than an increase in the number of muscle fibers. This process is stimulated by increased resistance exercise, such as weightlifting or resistance band training, which causes damage to the muscle fibers. As the damaged fibers repair, they become larger and stronger, leading to hypertrophy. It is important to note that while there may be a slight increase in the number of muscle fibers through hypertrophy, this is not the primary mechanism of muscle growth.
