Abstract
This research aims to compare the electrical activity of the antagonist muscles: triceps and biceps brachii, when performing maximum isometric contractions. The electromyographic technique was used to measure the electrical activity of these muscles. In the results it was noted that in the isometric contraction of the biceps and in the isometric contraction of the triceps there is activation of both muscles. According to the integration of different physiological mechanisms such as: motor control function, inverse myotatic reflex in coordination with the cerebellum, cerebral cortex and spinal cord, it is concluded that the electrical activity observed in the agonist muscle is greater in both cases due to a greater recruitment of muscle fibers, presenting a statistically significant difference with respect to the antagonist.
