What is your opinion on how muscles grow?
Muscles primarily grow two ways, which include sarcoplasmic and myofibrillar hypertrophy. If you recall from yesterday, we discussed a muscle fiber. A muscle fiber contains two areas that can grow; the sarcoplasm and myofilaments. The sarcoplasm is home to fluid, mitochondria, and parts of a cell that do not contract. The myofilaments are the part of the
muscle that contract. With sarcoplasmic (non-contractile) muscle growth, the cell increases in size because more fluid is pulled in, however in myofibrillar muscle growth, the contractile parts of the cell increase in number.
Tune in the rest of this week and next for the best way to target both types of muscle growth!
