This study aimed to implement carbohydrate mouth rinsing to verify its effects on record changes in the 2,000 meter overall sections of university rowing athletes along with their athletic performance based on the stroke, which is a basic skill of rowing. For the study, randomized, double-blind studies and crossover studies were applied to 10 university rowing athletes with 5 athletes placed into Group A and Group B and three 2,000 meter tests(in the first trial, only water was used, in the second trial, A group Carbohydrate Mouth Rinse(CMR), B group Placebo(PLA), in the third trial, A group PLA, B group) were conducted, each respectively a week apart, and the effects of carbohydrate mouth rinsing were compared and verified. The results of the study showed that completion of the initial 0-500m section was significantly shortened by CMR (p<.05, CON; 92.35±4.39s, CMR; 88.22±2.60s, PLA; 92.16±2.99s), and that peak force (CON; 722.93±58.19N/BW, CMR; 812.55±57.75N/BW, PLA; 738.23±54.95N/BW) and power (CON; 722.23±106.23W/BW, CMR; 970.16±103.92W/BW, PLA; 866.17±124.23W/BW) were significantly increased (p<.05). Results showed that carbohydrate mouth rinsing treatments enhanced force and power with regard to anaerobic metabolism and that they contributed to record time reductions in initial spurt sections(0-500m).

본 연구는 탄수화물 구강 헹굼을 실시하여 대학 조정선수들의 2,000m 전체 구간에서의 기록 변화와 함께 조정의 기본 기술인 stroke를 기반으로 한 운동수행능력에 미치는 효과를 검증하는데 목적이 있다. 연구를 위해 10명의 대학 조정선수들을 대상으로 무작위, 이중맹검 및 교차연구를 적용하여 5명씩 A, B 집단으로 구분하였고, 일주일 간격을 두어 총 3번의 2,000m 테스트(1차: 물을 이용한 구강 헹굼, 2차: A집단 Carbohydrate Mouth Rinse(CMR), B집단 Placebo(PLA), 3차: A집단 PLA, B집단 CMR)를 실시하여 탄수화물 구강 헹굼의 효과를 비교 검증하였다. 연구결과 초반 0-500m 구간에서 CMR(CON; 92.35±4.39s, CMR; 88.22±2.60s, PLA; 92.16±2.99s) 기록이 유의하게 단 축되었고, force의 peak(CON; 722.93±58.19N/BW, CMR; 812.55±57.75N/BW, PLA; 738.23±54.95N/BW) 와 power에 peak(CON; 722.23±106.23W/BW, CMR; 970.16±103.92W/BW, PLA; 866.17±124.23W/BW)에 서 유의한 증가를 나타냈다. 이러한 결과는 CMR 처치가 무산소성 대사와 관련해 force 및 power를 향상시켜 초반 스퍼트 구간(0-500m)에서 기록 단축에 기여하는 것으로 보인다.
