Abstract

The purpose of this study was to investigate the change of heart rate, blood lactate, blood pressure and MV O_2 during Taekwondo competition in males and females Taekwondo athletes, Data collected at the rest, competition, post immediate, recovery. The subject were consist of 8 males and 8 females in Taekwondo Athletes, The result of this study by analysis of variance of raw data from repetition measurement both male and female at the pre and post competition were as follows. 1. There was no significant difference of HR between male and female in competition, but between 1R and 2R and between 1R and 3 were significantly different. The highest HR of each round was 180∼189bpm, 90∼95% of HRmax. 2. There was no significant difference of blood lactate between male and female, but lactate was significantly increased as times went by, and especially at the post immediately 3R was increased three times at rest. 3. There was a significant difference of systolic pressure between male and female at each round. Systolic pressure of male athletes was 13∼22mmHg higher than female athletes after each round, and MV˙O_2 of male athletes was 1∼4.6mmHg·bpm^-3 higher than female, that was increased a few times at rest. As a result HR and blood lactate were no significantly different between male and female athletes in Taekwondo competition. But, blood pressure and MV˙O_2 in male athletes were higher than female. In conclusion, the results suggest that it is necessary to figure out the best way to develop athletic performance by applying individual exercise intensity or different program during the Taekwondo training.
