Question

Definition of isometric and isotonic contra tion in simle language

Answer 1

Isotonic literally means 'same tension,' where 'iso'- means 'the same' and 'tonic' refers to 'tension or force' - in this case, in the muscle. In an isotonic contraction, tension develops to a point and then remains constant while the muscle changes its length. In other words, motor units are activated to develop the necessary tension in the muscle. We utilize isotonic contractions when we move our limbs.
