고강도 단시간운동에서 Active Rest의 형태에 따른 Lactate변화가 RPE에 의한 운동지속에 미치는 영향

Abstract

In this study, while performing high-intensity exercise program with the same amount of exercise, it is divided into intensive type of general active rest (Intensive) and split type during exercise. The purpose of this study was to suggest a method for effective exercise fatigue control in high-intensity short-time exercise by comparing the change pattern of lactate and finding out how it affects exercise continuity through the score of the subjective exercise intensity scale RPE. The subjects of the study were 24 males in their 20s and 30s, divided into 12 I.G (Intensive Group) and 12 S.G (Split Group), and the changes in lactate and RPE were compared. As a result of the study, IG showed a statistically significant difference between 1st/2nd and 2nd/3rd (p<.001***), and SG showed a statistically significant difference between 1st/2nd and 2nd/3rd (p<.001***). Also, there was a significant static correlation between lactate and RPE at the 1st (p<.001***) and 2nd (p<.05*). Therefore, 1. In high-intensity short-time exercise, the intensive form of active rest showed an efficient decrease after a radical increase in lactate, and the split form showed a gradual improvement by suppressing the radical increase in lactate. 2. In high-intensity short-time exercise, the intensive form of Active Rest is judged to be impossible to continue exercise after a radical increase in lactate in terms of the RPE score. 3. In high-intensity short-time exercise, it was concluded that the split form of Active Rest is possible to continue exercise due to the gradual increase in lactate in terms of RPE score.
