Increase in Myofibrillar Volume?

Sarcoplasmic hypertrophy is the increase in volume of the sarcoplasm within the muscle fiber causing growth. Myofibrillar hypertrophy is the increase in the amount of myofibrils within the muscle fiber causing growth.

Does myofibrillar hypertrophy increase size?

When training for myofibrillar hypertrophy, actin and myosin contractile proteins actually increase in number and add to the actual strength of a muscle, as well as a small increase in the size of the muscle, due to the body treating the small 'tears' in the muscle fibres as injuries, sealing and strengthening them ...

How does myofibrillar hypertrophy increase strength?

Myofibrillar hypertrophy is essentially muscle fiber growth. A myofibril is the contractile portion of a muscle fiber. Without myofibrils, our muscles could not move. When myofibrillar hypertrophy takes place, the number of myofibrils in a muscle increases, which in turn increases the muscle fiber density and strength.
