"Muscle hypertrophy" refers to the increase in the size of the muscles. A context clue here is the word "hypertrophy." The prefix "hyper" means<em> "over"</em> or <em>"exaggerated.</em>" This is synonymous to the word<u> "growth."</u> Thus, this explains the answer.
Muscle contraction comes in two forms: isotonic and isometric. Isotonic means that the muscle has a sustained tension as it grows or changes. Isometric means that the muscle contracts without any change in its length. So, this makes the statement true.
