초록
이 연구에서는 근력 불균형의 지표로써 최대반복횟수를 사용할 수 있는가를 검토하는데 그 목적이 있다. 연구 대상은 저항운동 경력이 1년 이상인 성인 남성 11명(연령; 26.6±2.5, 신장; 173.4±4.6, 체중; 74.1±5.8)으로 하였으며, 모든 피험자는 신체조성과 도수근력검사를 측정한 후에 chest press를 이용하여 주동근(큰가슴근)의 1RM 및 우세측과 비우세측을 구분하여 최대 수의적 등척성 수축력(MVIC)을 측정하였다. 1RM의 80%의 two-arm chest press, 1RM의 40%의 one-arm chest press의 근활성도 및 최대반복횟수를 각각 측정하였다. 반복 속도는 1회 반복 시 4초(등장성 수축: 2초, 신장성 수축: 2초)안에 수행하도록 동일하게 설정하였다. 1RM의 80%의 two-arm chest press 및 1RM의 40%의 one-arm chest press의 근활성도는 비우세측의 주동근과 비교하여 우세측의 주동근에서 각각 유의하게 낮은 것으로 나타났다(p < .01, p < .05). 반면에, 도수근력 검사 및 최대반복횟수는 비우세측의 주동근과 비교하여 우세측의 주동근에서 각각 유의하게 높게 나타났다(p < .05, p < .01). 최대반복횟수는 도수근력 검사(rho=.331, p=.320)와 상관관계가 나타나지 않았지만, 1RM의 80%의 two-arm chest press의 근활성도(rho=-.730, p=.011)와 유의한 음(-)의 상관관계가 나타났다. 따라서 이 연구에서 최대반복횟수는 근력 불균형의 지표로서 사용할 수 있다고 생각된다.
Abstract
The purpose of this study was to determine whether maximum repetition number can be used as an indicator of strength imbalance. Eleven healthy, resistance-trained males were tested for one repetition maximum (1-RM) the chest-press exercise, and than manual muscle testing (MMT), two-arm at 80% of 1-RM and one-arm at 40% of 1-RM in the pectoralis major were measured for the maximum voluntary contraction (%MVC) and maximum number of repetitions during the chest press exercise. Exercise velocity was constantly 4 seconds (concentric: 2-s, eccentric: 2-s) per repetition. The changes in %MVC were significantly higher in non-dominant limb (NDL) compared with dominant limb (DL) pectoralis major during two-arm chest press (p < 0.01) and one-arm chest press exercise (p < 0.05). In contrast, the changes in MMT (p < 0.05) and maximum repetition number (p < 0.01) were significantly higher in DL compared with NDL during one-arm chest press exercise. There was no correlation between maximum repetition number and MMT (rho = 0.331, p = 0.320). However, maximum repetition number was significantly negative correlated with %MVC in two-arm chest press (rho = -0.730, p = 0.011). It is possible that maximum repetition number can be used as an indicator of strength imbalance.
