조정선수의 로잉에르고미터 2,000m 수행방법에 따른 카테콜라민, 코티졸, 활성산소 및 젖산의 비교분석

The purpose of this study was to investigate the performing 2,000m rowing ergometer facing strategy on catecholamines, cortisol, reactive oxygen species(ROS) and lactate. Rowing method was performed with a pacing strategy using 6-minute all-out threshold critical power and a 2,000-m pacing strategy without any control. The variables of catecholamine, cortisol, ROS, and lactate were measured in all the participants. The findings of this study were as follows; the even pacing method was found to be faster than at 2,000m rowing record. And all the variables showed the interaction effect. Even pacing method showed higher catecholamine activity immediately after exercise and 20 minutes after recovery than the free pacing method. Cortisol was found to be higher in the free pacing method immediately after exercise and 20 minutes after recovery. ROS was found to be higher in the free pacing method than in the rest 20 minutes after exercise. Lactate result showed higher pacing method than free pacing method. These results suggest that the application of the even pacing method using the critical power measurement has a positive effect on the fatigue delay and the maximum performance of the athletes.
