전기근육자극(EMS)을 활용한 유형별 스트레칭이 태권도 선수의 정서에 미치는 영향

Abstract

The purpose of this study is to compare the effects of stretching by type using Electrical Muscle Stimulation(EMS) on the emotions of Taekwondo athletes through EEG. In this study, eight Taekwondo athletes from the D city unemployment team were selected as subjects. Three-static Electrical Muscle Stimulation(EMS), dynamic Electrical Muscle Stimulation(EMS＋PNF), and basic stretching (Nor)-treatment were performed in random order, and EEG was measured before and after each treatment. The collected data was analyzed by dividing it into alpha, beta, and theta waves by frequency. The results of this study are as follows. First, after stretching using EMS, alpha waves were most active in treatment using only EMS stimulation. In addition, in all three treatments, alpha wave activity was observed after treatment. Second, beta wave activity was observed in all three treatments after stretching using EMS. Third, theta wave activity was observed in all three treatments after stretching using EMS. Also, the most active theta wave activity was found in treatments that presented only EMS stimulation. Summarizing the above results, I think that stretching using EMS can improve the positive emotions of Taekwondo athletes and have a positive effect on performance. In the future, I would like to use stretching with EMS in another more exercises.
