Will a muscle hypertrophy if myofilaments also increase in both size and number?
A) Yes, this supports the theory that the number of muscle fibers increase because fibers split in response to training.
B) No, this contradicts the theory that myofilament increase only occurs in males.
C) Yes, this supports the theory that more blood is required to supply the muscle, thus, also increasing the number of capillaries.
D) No, this contradicts the theory that the number of fibers is genetically determined and does not increase with training.
E) Yes, this supports the theory that individual muscle fibers themselves increase in cross-sectional diameter.

Question

Quizplus · Accepted Answer

Muscle hypertrophy involves the increase in the size of individual muscle fibers, which can occur through an increase in the size and number of myofilaments within those fibers, leading to an increase in the muscle's cross-sectional diameter.
