Contraction and relaxation are two opposites. They work together when the muscles of the body work. A good example is the contraction and relaxation of the heart. The contraction allows blood to be distributed to the parts of the body while the relaxation allows the heart to be oxygenized and therefore fill up blood to be distributed to the whole body.
