dynamic contraction
Dynamic contraction refers to a type of muscle movement where the muscle actively shortens to create movement, such as lifting or walking. During this process, the muscle's fibers generate force by contracting, which allows bones to move at joints. It contrasts with static (isometric) contractions, where the muscle tenses without changing length, like holding a weight steady. Dynamic contractions are essential for most everyday activities and exercise routines, enabling smooth, controlled motion through the coordination of muscle groups.
