Many different bodily movements depend on smooth muscle contractions. Medical News Today has strict sourcing guidelines and draws only from peer-reviewed studies, academic research institutions, and medical journals and associations. Compare a 3D model of a sarcomere to its electron micrograph and observe the changes that take place during contraction and relaxation. Examples include weightlifting, sprinting, climbing, and jumping rope. This type of muscle contraction is controlled not by the central nervous system in the brain but by the autonomic nervous system, the portion of the peripheral nervous system that coordinates involuntary actions like breathing and heart rate.
