Myofibrillar proteins
Myofibrillar proteins are the main building blocks of muscle fibers, responsible for muscle contraction and strength. They include key proteins like actin and myosin, which form organized structures called myofibrils. During muscle movement, these proteins slide past each other, shortening the muscle. Myofibrillar proteins are essential for muscle function and develop through training and exercise. They also influence muscle quality and recovery. In simple terms, they are the crucial proteins that allow your muscles to contract and produce force, enabling movement and activity.
