This study selects total 15 subjects including 5 Taekwondo athletes, 5 weight lifters and 5 general students at C university as subjects of the study, gives them green tea extract, examines and analyzes the influences of taking green tea extract on changes of serum lipid concentration and serum enzymes after complex exercise for four weeks with a view to trace activation of serum lipid and enzymes (LDH & CK) and obtains the following conclusions.
1. Changes of Serum Lipid
1) As a result of comparing differences according to groups and change of times, change of total cholesterol (T-C) showed no statistically significant difference. But, there was statistically significant difference before exercise and after one week of exercise.
2) As a result of comparing differences in serum lipid HDL-C according to groups and change of times, there were statistically significant differences in groups and change of times. Mean of Taekwondo athletes was higher than that of weight lifters and general students.
3) As a result of comparing differences in blood lipid LDL-C according to groups and change of times, there was no statistically significant difference in groups and change of times.
4) As a result of comparing differences in blood lipid TG according to groups and change of times, there was no statistically significant difference in groups but there were statistically significant difference in change of times.
2. Changes of Serum Enzymes
1) As a result of comparing differences in serum enzyme LDH according to groups and change of times, there was no statistically significant difference in groups but there were statistically significant difference in change of times.
2) As a result of comparing differences in serum enzyme CK according to groups and change of times, there was no statistically significant difference in groups but there were statistically significant difference in change of times. There was no difference before exercise and after one week of exercise, there was statistically significant difference before exercise and after two weeks of exercise, before exercise and after three weeks of exercise and it is considered that as time extends, effects will be more.
3) Effects of Green Tea Extract (Catechin)
It is known that intake of catechin extract improves lipid metabolism, prevents complications related to metabolism and has various physiological activation functions such as anti-inflammatory, anti-allergic and anticancer functions as natural antioxidant and recently it is found that it has preventive effects of circulatory diseases by improving blood pressure and blood lipid. This study also considers that it has affirmative influences on physical composition of athletes and improving blood lipid and peroxide lipid and is very effective in preventing and improving arteriosclerosis, cardiovascular diseases, diabetes and abdominal obesity.
3. Suggestions
This study observes serum lipid and LDH, CK by making athletes with high intensity exercise have green tea extract which is known as having several physiological functions, examines the influences of taking green tea extract on cell damage and finds out it has the affirmative influences on blood lipid and serum enzymes, but period of taking green tea extract is too short as one month and it is considered that more duration of taking it is needed for further study and research of amylase, alkalic phosphatase (ALP), electrolyte, metal and transaminase (GOT, GPT) is required.
