Shoulder Girdle Muscles Activation of Compound Archers

Background.Sports performance is the way sports participation is measured.Sports performance is a complex mixture of biomechanical function, emotional factors, training techniques, tactics, and many other aspects.Objectives.This research aimed to examine the muscle activation of compound archers during shooting.Methods.Twenty-four compound archers, consisting of 10 males and 14 females, who met the inclusion criteria were included in the study.Athletes were divided into three according to their shooting score.A wireless surface EMG system (Trigno EMG sensor, Delsys Inc., USA) measured activity on the middle deltoid, posterior deltoid, middle trapezius, lower trapezius, triceps, and anconeus muscles.The measurement was recorded of nine shots, and the distance between the archers and the target was 18m.Results.There was no statistically significant difference between the elite, intermediate, and junior compound archers.No significant difference was found between the genders upon comparing muscle use during shooting.However, in terms of percentages, compound archers employed the most sustained contractions of the posterior deltoid, middle trapezius, anconeus, and lower trapezius muscles when shooting.During shooting, they also used the most prolonged contraction of the posterior deltoid, middle trapezius, anconeus, and lower trapezius muscles. Conclusion.It can be concluded that these three findings show the same trend toward using muscles among compound archers during shooting.Therefore, more research on compound categories needs to be conducted to further findings and comparisons in the future.
