Question

Quizplus · Accepted Answer

Hypertrophy is the increase in size of existing muscle fibers, which is the primary mechanism behind muscle growth due to strength training. Hyperplasia, the increase in the number of muscle fibers, is not a proven mechanism for muscle growth in humans. An increase in muscle water content may contribute to short-term fluctuations in muscle size, but is not a significant factor for long-term muscle growth.
