Manifestation of asymmetry in muscle activity during the execution of shots from a recurve bow

The purpose of the study was to identify the characteristics of asymmetry in the activity of bilateral skeletal muscles during different phases of the shot from a recurve bow. Research methods and organization. During shooting, electromyograms were recorded from 48 leads in 18 bilateral muscles of the torso and upper limbs in five highly qualified athletes. Muscle activity asymmetry was identified in the phases of the bow shot: "drawing," "full draw," "release," and "follow-through." Research results indicate a predominance of right-sided muscle activity with the left-sided stance of the archer. The highest values of the asymmetry coefficient were identified in the "full draw" and "release" phases. In the "drawing the string" phase, predominance of EMG activity was noted in muscles responsible for lifting and aiming the bow at the target on the left side: the trapezius, deltoid, and serratus anterior muscles. In the subsequent phases, EMG activity predominates in the right deltoid muscle.
