Isometric Muscle Contraction

 

contraction of a muscle expressed in an increase in its tension while its length remains unchanged (for example, contraction of a muscle of an extremity, both ends of which are immovably attached). In the body, the tension developed by muscles in an attempt to lift an excessive load approximates isometric muscle contraction.
