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.

Previous studies have found absolute strength to be an independent factor contributing to skeletal muscle fatigue during isometric muscle contractions (Hunter and Enoka, 2001).
Interruption of muscle blood flow by means of significant intramuscular pressure has been extensively studied during sustained isometric muscle contractions, many of which have been performed using handgrip exercise (Barnes, 1980; Kagaya and Homma, 1997).
