contraction velocity

Contraction velocity refers to the speed at which muscle fibers shorten when they contract. When a muscle pulls to produce movement, the muscle fibers slide past each other, causing the muscle to become shorter. The velocity of this shortening influences how quickly a movement occurs; for example, a fast contraction allows for quick actions like sprinting, while slower contractions are involved in tasks requiring precision or holding a position. Overall, contraction velocity is a key factor in muscle performance, affecting the speed and strength of movements.
