초록
본 연구의 목적은 주짓수 토너먼트 시합을 가정하여 고강도 스파링을 실시하여 각 라운드별 직후와 24,48,72시간 후 혈중젖산농도를 측정해 피로수준과 회복경향을 알아보고, 선정한 상체근육 9부위의 통증정도를 파악하고자 하였다. 연구대상은 전국 주짓수 대회 참가·경력자 20명을 표집, 2집단으로 각각 10명씩 무선 배정하였으며, 휴대용 젖산측정 / 압통측정 장비를 이용하여 각 변인을 측정하였다. 이원분산분석에 따른 사후비교 결과, 첫째, 스파링 시 젖산농도수준은 시기별에는 유의한 차이가 나타났고, 포지션과 시기별 간 상호작용에서는 유의한 차가 나타나지는 않았으나, 상위포지션집단에서 젖산이 높게 나타나는 경향을 보였다. 둘째, 압통척도는 라운드 전과 비교하여 4라운드 직후와 24, 48, 72시간 후에 유의한 차를 보였으며(p<.05), 포지션과 시기별 압통역치 간 상호작용에서삼두근(p<.05), 이두근(p<.05), 전완굴근(p<.05), 복직근(p<.001)은 유의한 차이를 나타내었다. 이상의 결과, 상위포지션에서 각 라운드 후와 시기별로 젖산농도 수준이 높게 나타났고, 9부위의 근육들 중삼두근, 이두근, 전완굴근, 복직근의 사용이 하위포지션에 비해 많은 것으로 나타났다. 따라서 고강도 불완전 휴식형태 트레이닝을 통한 높은 젖산수준에서의 운동수행력 증가는 주짓수 수련자들의경기력 향상에 도움을 줄 것이라고 사료된다.
Abstract
The purpose of this study was to investigate the fatigue level and recovery tendency of blood lactic acid concentration after 24, 48, 72 hours and after each round, and to investigate the pain level of the upper body muscle 9 selected by the high intensity sparring on the assumption of the Jujitsu tournament.,The subjects of this study were 20 participants and 20 experienced participants in the national jujitsu competition, and 10 participants were randomly assigned to each group. Each variable was measured using portable lactic acid measurement / pressure pain measurement equipment. As a result of post-comparison according to two-way ANOVA, first, the level of lactic acid in sparring showed a significant difference by period, and there was no significant difference in interaction between position and period, but the Top position group showed a tendency to show high lactic acid due to repeated use of Upper extremity small muscles. Second, the pressure pain threshold showed a significant difference after 4 rounds, 24, 48, 72 hours, compared to before round (p<.05). there was a significant difference in the triceps (p<.05), biceps (p<.05), Wrist flexor (p<.05) and rectus abdominis(p<.001). The results showed the increase of exercise performance ability at lactic acid through high intensity incomplete resting type of training will helpful to improve jiu jitsu performance.
