초록
[목적] 본 연구는 프로씨름 선수들의 체급별, 우수·비우수 선수 간 ACTN3 유전자 다형을 확인하고 종목 특성에 부합하는 genotype을 선별하기 위해 수행되었다. [방법] 피험자는 현재 프로씨름 선수로 활동 중인 남자 선수 148명을 대상으로 진행되었으며, ACTN3의 체급 간 및 우수·비우수 선수들의 차이를 알아보기 위해 카이제곱 검정(χ2-test) 교차분석(cross tabulation analysis)을 실시하였다. [결과] 프로씨름 선수들의 유전자형 및 대립유전자에서는 유의한 차이는 발견되지 않았다. 하지만 우수/비우수선수로나누어 비교하였을 경우에는 우수선수에서 R-allele의 빈도가 높고, XX genotype은 낮은 것으로 나타났다(χ2=5.545, df =1, p =.019). [결론] 이를 근거로 선수 선발 및 훈련 프로그램 구성 시 기초자료로 활용한다면 종목 특성에 부합하는 선수 양성 및 경기력 개선에 도움이 될 것으로 여겨진다.
Abstract
PURPOSE This study aimed to identify ACTN3 gene polymorphisms among professional ssireum players by weight class and between elite and non-elite players, and to select genotype that matches the characteristics of the sport. METHODS The subjects of this study were 148 male athletes currently working as professional ssireum players. Chi-square test cross-tabulation analysis was conducted to examine the differences in ACTN3 genotypes between weight classes and between elite and non-elite players. RESULTS There were no significant differences in allele or genotype between ssireum players, but there were significant differences in R-allele and XX genotype. CONCLUSIONS Players with the R-allele type of the ACTN3 gene were more often classified as elite. Using this marker as a basis for organizing a player selection and training programs would be more effective in training those that match the characteristics of elite players of the game.
