Hipertrophy

There are two types of hypertrophy: the transient or acute, which is muscle swelling after training, so it is transient and short-lived, and chronic hypertrophy, which is divided into sarcoplasmic and myofibrillar. In sarcoplasmic, the muscle increases the sarcoplasm, which is the semifluid substance that is between the myofibrils (so that the size of the muscle is increased and the effect is long-lasting); This type of hypertrophy does not increase the level of strength. In the myofibrillar, they increase both the size and the number of myofibrils that make up the muscular tissue, since, when they break in training, to avoid later breakages they multiply their number and increase their size, so a remarkable effect is produced in the increase in both the size and strength of the muscle.

This cell growth is due to an intensification of the synthesis of its structural components; This, as it is not accompanied by division, results in an increase in size.
