엘리트 태권도 선수의 경기 중 심박수, 혈중 젖산, 혈압, 심근산소소비량의 변화

Abstract

In this study, by observing the changes in heart rate, blood lactate, blood pressure, and myocardial oxygen consumption during the entire competition, male and female Taekwondo elite athletes performed 3 rounds of 3 minutes for men and 3 times for 2 minutes for women, respectively, the exact exercise intensity of Taekwondo was evaluated. The purpose is to provide basic data for understanding and to present the theoretical basis for planning scientific training. The subjects of this study consisted of 16 university players, 8 male and 8 female. Heart rate, blood pressure, and blood lactate were measured, and myocardial oxygen consumption was calculated from the measured systolic blood pressure and heart rate. Measurement time is at rest, end of round 1, rest 1(1 min), end of round 2, rest 2 (1 min), end of round 3, rest 3 (1 min), recovery period (3 min) after game 8 times classified as.<BR>As a result of this 1. There was no significant difference between the sexes in the change of heart rate in the Taekwondo competition, and there was a significant difference between the 1st/2nd and 1st/3rd rounds during the R competition, which corresponds to 90-95% of the maximum heart rate. 2. There was no significant difference between the sexes in the change of blood lactate, and there was a significant difference at the end of each rotation, which corresponds to an approximately 3-fold increase at the end of the 3rd rotation compared to the rest. 3. As for the change in blood pressure, there was no significant difference in systolic blood pressure between the sexes, and there was a significant difference in diastolic blood pressure. Male athletes were higher than female athletes by time. 4. The change in myocardial oxygen consumption showed a significant difference between the sexes, and it was found to be about 2-3 times higher than at rest.
