Resistance training will stimulate muscle growth by a variety of mechanisms. Which of the following is considered to be the least likely mechanism of increasing muscle size?

Question

Quizplus · Accepted Answer

Rapid hyperplasia of muscle fibers is considered the least likely mechanism for increasing muscle size in response to resistance training. While resistance training can lead to increases in muscle size through mechanisms such as increased water content, thickening of connective tissue, multiplication of myofibrils, and hypertrophy of muscle cells and myofibrils, the concept of muscle fiber hyperplasia (an increase in the number of muscle fibers) is less supported by evidence in humans.
