Question 1 - True

Question 2 - True

Explanation:

Muscle hypertrophy refers to growth in the size of  muscles and muscle fibers and usually occurs as a result of physical activities such a weight-lifting. The prefix "hyper" means "over" so it is usually associated with something increasing.

Isotonic muscle contractions are muscle contractions where the length of the muscle changes. In contrast, isometric muscle contractions are muscle contractions in which the length of the muscle does not change
