Effect of Different Exercise Mode on Reactive Oxygen Species Production and Blood Flow Regulation
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.40 Vol.40】
ABSTRACT
Reactive oxygen species （ROS） production during exercise is thought to be relatedto an improvement in cognitive function. We hypothesized that high intensity intervalexercise induced ROS production is lower compared with continuous high intensityexercise. Also, high intensity interval exercise contributes to improvement in cognitivefunction because of lower ROS production. In this experiment, in order to verify thishypothesis, we examined the influence of different exercise mode on ROS production.Continuous high intensity and high intensity interval exercise were performed, andthe thiobarbituric acid reaction product （TBARS） value in plasma before and aftereach exercise was calculated as an index of ROS production. TBARS value increasedsignificantly immediately after continuous exercise, while TBARS value tended toslightly increase after interval exercise, but significant difference was not observed.In the present study, the validity of the hypothesis was proved by showing that thedifference in exercise mode shows that ROS production is different despite a similarwork exercise. This finding suggests that there is the physiological advantages ininterval exercise as a therapy for preventing dementia.
