The objective of this study consists in inquiring in to herpetology, plasma protein, and chemical changes in lithicaacid, and the resultant findings are revealed, as follow: 1. Herpetology 1) Red Blood Cell (RBC) Red blood cells show the lowest value at rest, 4.51 count/mm3, in the athlete group, while the highest value right an after an exercise,4.76 count/mm3. The results of t-tests both an rest and right after an exercise do not present any significant difference. 2) White Blood Cell (WBC) White blood cells show the lowest value at rest, 5.67 count/mm3 in the non-athlete group, while the highest value right after an exercise, 12.9 count/mm3 in the athlete group. The results of t-tests do not represent any significant difference between the two groups at rest, but a significant difference right after an exercise by the t value of 9.3114. 3) Hemoglobin Hemoglobin presents 16.2 g/dl at rest in the non-athlete groups, 14.8 g/dl at rest in the athlete group, while it shows 17 g/dl right after an exercise in the non-athlete group, and 15.5 g/dl in the athlete group. However, it shows a 9.46% higher at rest and a 9.68% higher value right after an exercise in the non-athlete group, as compared with that of the athlete group. 4) Hematocrit Hematocrit exhibits 41.8% at rest in the non-athlete group, 45% at rest in the athlete group, whereas 45.7% right after an exercise in the non-athlete group, 43.8% in the athlete group. This reflects a 7.6% higher at rest and 4.34% higher value right after an exercise. In consequence, herpetology before and after Harvard step tests conducted on the national level Taekwondo champions and general students shows in general higher values right after an exercise than at rest in both the athlete and non-athlete groups. These results indicate that Taekwondo champions have better aerobic ability than the general students.

Taekwondo became a famous sport as a olympic sport and it made change essential of it's own displine what we called Su-Ryen. Traditional Su-Ryen of Taekwondo always emphasis that unity of mind and body and this is the main goal for the practicing Taekwondo. But now these kinds of values are gone in modern Taekwondo practice. Everything is focus on the administration of Do-Jang and It's concentrated in increase of the income by inhance number of students. The purpose of this research is try to find out that the possibilities of put values of traditional Taekwondo Su-Ryen to a morden Taekwondo Su-Ryen. There are two concepts exist in discipline of Taekwondo at same time. First on is traditional conception of discipline itself and second one is new concep of discipline fits on sport called as 'training'. But currently training has been used in stead of discipline in the Taekwondo. Sabum changed to coach or instructor. Dojang changed to gym and Dobok changed to training uniform. And these kinds of changes lead the changes in philosophical values of Taekwondo discipline itself. Dan-Ryen is the most importaant meaning of discipline but this is almost disappears in cullent concept of training. The main concept of training is skill which the main factor of competition. Training is focus on practice of skill and the superial goal of the training is winning the game. So themain concept of discipline like cleaning mind and body, respcts sabum are gone. For the developments of Taekwondo in the future, the values of Taekwondo Su-Ryen must be rebuild-up.

The purpose of this study was to examine the effects of green tea beverage supplement on blood lipid component(TC, HDL-C and LDL-C) and lipid metabolism variable(VO<sub>2</sub>, RER and Fkcal) following three different groups(supplement before exercise[BE], during exercise[DE] and after exercise[AE]). 24 healthy male collegiate students participated as subjects after signing an informed consent. The submaximal exercise intensity of this study was the 60% VO<sub>2</sub>max of subjects. To comparative analysis on the effect of lipid metabolism post-exercise(60min) with green tea beverage for 4-weeks it was compared the oxygen consumption(VO<sub>2</sub>), respiratory exchange ratio(RER), fat kilocalories(Fkcal), TC, HDL-C and LDL-C following every supplement times. First, there were not significant differences in fat metabolism included VO<sub>2</sub> RER and Fkcal among supplement times. However, the VO<sub>2</sub>, RER and Fkcal on measurement time was significant in the within groups(p<.05). Second, there were not significant differences in TC, HDL-C and LDL-C among supplement time and measurement time. However, the TC, LDL-C values was decreased in the AE and the HDL-C values was increased similarly in the all groups. Especially, AE and BE treatment has effective than DE for recovery periods.
