Dependence of electrical activity of a muscle on its length during development of a constant force

  • T. B. Kireeva


The dependence of the integral electromyogram (EMG) on the length of the muscle during the development of constant force was investigated in relation to the human biceps brachii muscle, while performing flexion at the elbow in a horizontal plane against a constant force of resistance. Both with a static load and during movement the integral EMG is increased several times during shortening of the muscle. The causes of the increase in electrical activity are discussed.
