(concentric action) the 'true' form of contraction of a muscle in which it shortens against a load (which may be only that of gravity on the relevant body part), and so does positive work. Hence concentric exercise: that in which the principal agonists act concentrically.See also muscle contraction.oncentric contraction contraction resulting in shortening of a muscle, used to perform positive work or to accelerate a body part. It is metabolically more demanding than an eccentric contraction. Called also shortening contraction.
