Full Answer
C.Muscles increase in size✓ Correct
The correct answer is C. Muscular hypertrophy is the increase in the size of muscle cells, which leads to an overall increase in muscle size, typically as a result of strength training.
Muscular hypertrophy is a physiological adaptation to regular anaerobic exercise, such as weight training. It involves an increase in the cross-sectional area of muscle fibres, leading to an increase in the overall size and strength of the muscle. The opposite process, a decrease in muscle size due to lack of use, is called muscular atrophy.
Common mistakes
