Explanation:

Detailed explanation-1: -Skeletal muscle hypertrophy is the increase in muscle fiber cross sectional area that is accompanied by an increase in muscle volume and mass. Hypertrophy occurs in response to a higher load on muscle which activates inducible agents such as IGF-1.

Detailed explanation-2: -Muscular hypertrophy refers to an increase in muscle mass. This usually manifests as an increase in muscle size and strength. Typically, muscle hypertrophy occurs as a result of strength training, which is why it is normally associated with weight lifting.

Detailed explanation-3: -This study using a different method, supports our earlier observations that prolonged weight-lifting exercise significantly increases the total number of muscle fibers.
