윤재량, 임승길. 7-10RM 방식에 의한 대학 레슬링 선수 1-RM 간접 추정식의 정확성. 운동과학, 제16권 제1호. 39-46, 2007. 본 연구의 목적은 7-10RM을 적용하여 1-RM을 간접 추정할 경우 추정된 1-RM의 정확성을 비교평가하여 7-10RM을 이용한 1-RM의 간접 추정식의 효용성과 가장 정확한 추정식을 제시하는 것이다. 본 연구의 대상은 H대학교에 재학 중인 레슬링 선수 34명을 대상으로 하였다. 1-RM 측정항목은 bench press, lat pull down, squat를 이용하였으며, 측정 프로토콜은 NSCA에서 권장하는 방법을 변형하여 적용하였다. 자료분석은 One-Way ANOVA 를 이용하여 실제 1-RM과 7-10RM을 적용하여 추정된 1-RM간의 차이 검증을 분석하였으며, Pearson product-moment correlation 을 이용하여 상관분석을 하였다. 유의수준은 p<.05로 설정하였다. 실제의 1-RM과 7-10RM을 이용하여 Brazyki, Epley, Lander, O'Conner et al., 이석인과 임승길이 제시한 간접 추정식에 의해 추정된 1-RM간에는 모두 유의한 차이는 없다. 실제의 1-RM과 추정된 1-RM간의 상관관계는 bench press는 r=.910~.924, lat pull down은 r=.844~.855, squat는 r=.906~.930로 매우 높은 상관관계를 가지고 있다(p<.001). 이러한 결과를 종합해 볼 때, 레슬링 선수의 경우 Brazyki, Epley, Lander, O'Conner et al., 이석인과 임승길이 제시한 1-RM 간접 추정식에 7-10RM을 적용하여 간접 추정할 경우 매우 정확하게 1-RM을 간접 추정할 수 있다.
Abstract
Yoon, J.R., Lim, S.K. Accuracy of 1-RM prediction equations from 7-10RM in college wrestlers. Exercise Science, 16(1): 39-46, 2007. This study examined the accuracy of 1-repetition maximum (1-RM) prediction equations from 7-10RM on bench press, lat pull down, squat for 34 college wrestlers(21.2±0.98 years). All subjects were completed 1-RM and 7-10RM test by bench press, lat pull down, squat. 1-RM and 7-10RM test protocols were applied modified NSCA 1-RM measuring protocol. One-Way ANOVA was applied to identify whether the predicted values were significantly different from the actual 1-RM measurement. And correlation was applied to access the accuracy of using the predicted 1-RM by generating coefficients between predicted and actual 1-RM measurements. Significance was determined at the 0.05 level of significance. There was no significant difference between the actual 1-RM and the 6 predicted 1-RM scores of wrestlers. Correlations between the actual 1-RM and the 6 predicted 1-RM scores demonstrated a positive relationships for all exercise(bench press: r=.910~.924; lat pull down: r=.844~.855; squat: r=.906~.930). Brazyki, Epley, Lander, O'Conner et al., Lee and Lim equations are accurately and useful methods when 7-10RM is apply.
