The purpose this study was to investigate the distribution of VO₂max in Taekwondo competition. Subjects as a T group were seven well-trained Taekwondo players. Control group was composed of seven healthy male students who taking Taekwondo club in D university. With K4b2 telemetry, VO₂max was determined for each subject by administering a treadmill exercise test(5% slope, start speed: 120m/min, increased 20m/min each 2min). Data were analyzed by ANOVA with post hoc-test The 0.05 level of significance was as critical level for the study The results are as follows; The study has shown that covering all round in the Taekwondo competition, the Taekwondo player group was over 81% VO₂max 55.88%, 71~80% VO2max 17.20%, below 70%, VO₂max 26.92%, and the control group was over 81% VO₂max 47.35%, 71~80% VO₂max 14.55%, below 70% VO₂max 38.10%. Putting the above-mentioned together, we can assume that in the Taekwondo competition, energy recruitment is anaerobic 55% or so, aerobic 45%. To develop performance of Taekwondo, it is fit that training have to be composed of 60% over 81%VO₂max at least. In the future, I think that it will be necessary to find how to classify the ratio of ATP-PC system which was brought about in the Taekwondo competition, that of lactate system and aerobic on the metabolism.

The purpose of this study was to investigate the changes of blood lactate, LDH and CPK in Taekwondo competition. Subjects as a T group were seven well-trained Taekwondo players. Control group was composed of seven healthy male students who taking Taekwondo club in D university. With K4b^2 telemetry, VˇO_2max was determined for each subject by administering a treadmill exercise test(5% slope, start speed: 120m/min, increased 20m/min each 2min). Data were analyzed by ANOVA with post hoc-test The 0.05 level of significance was as critical level for the study In lactate concentration of rest, the Taekwondo group was lower than the control group, but there was no significance. In LDH and CPK activity of rest, the Taekwondo group were significantly(p<.05, p<.01) higher than the control group. In the Taekwondo competition, lactate concentration and LDH, CPK activity in both of the group were all more significantly (p<.05, p<.01, p<.01) after the 3rd round than in the 1st and 2nd round. Putting the above-mentioned together, we can assume tat CPK is related to ATP-PC system, while lactate and LDH are connected with lactate system. In the future, I think that it will be necessary to find how to classify the ratio of ATP-PC system which was brought about n the Taekwondo competition, that of lactate system and aerobic on the metabolism.
