The purpose of this study is to investigate the kinetics of reactive oxygen species and total antioxidant capacity during acute moderate treadmill running. Twelve healthy men ran treadmill at a intensity of 70% of the participant’s VO2max for 90 minutes. Blood samples were taken from finger in pre-exercise, 30 minutes, 60 minutes, 90 minutes of exercise for measuring the blood lactate, derivatives of Reactive Oxygen Metabolites (d- ROM), and biological antioxidant potential (BAP). During the treadmill running, respiratory gas analysis was also performed. independent t-test and one-way ANOVA were performed to compare the differences. The results were summarized as follows: 1. The differences between pre and post training were significant in reactive oxygen and total antioxidant capacity(p<.05) 2. The changes of reactive oxygen were significantly increased by aerobic training, and there were significant differences among exercise durations(p<.05). 3. The changes of total antioxidant capacity were not significant differences between training intensity groups(p>.05), and there were significant differences among exercise durations(p<.05). As shown above, the occurrence of reactive oxygen and total antioxidant were altered by exercise duration. In other words, the occurrence of reactive oxygen species were significantly increased in 30 minutes of exercise and total antioxidant capacity was significantly increased in 60 minutes of exercise. In conclusion, within 60 minutes of exercise might be suitable for the beginners in the point of the defending the cell against reactive oxygen by exercise.

현대사회에 있어서 신체활동 연구의 주요 탐구과제는 ‘신체활동을 통한 교육’으로부터 ‘인간의 기본적인 움직임’을 목표로 하는 스포츠적인 움직임을 중심으로 한 생명 활동의 개념으로 급속히 변화되고 있는 추세이다. 이러한 환경변화에 대응하기 위하여 본학회는 ‘체육’적인 요소에서 ‘스포츠’적인 요소를 중심으로 한 학문적 정체성을 견고히 하고, 정기적인 학술지 발간과 학술활동을 통해 한국스포츠츠 문화의 발전과 학문적인 발전에 기여하는데 그 목적이 있다.
