The purpose of this stydy was the investigation on the changes in Total Cholesterol (T-Chol), High Density Lipoprotein - Cholesterol (HDL-C), and HDL-C/T-Chol ratio accompanied with the progress of exercise treatment. Eight untrained subjects (three men and five women, 40~56yrs, T-Chol>230mg/dl or HDL-C/T-Chol<25%) comprise of this study. Exercise prescription was follow : 1. Quality of exercise : the whole exercise (bicycle ergometer, jogging). 2. Intensity of exercise : 60%VO2max. 3. Duration of exercise : 20minutes 3set (interval 5minutes) 4. Frequency of exercise : 32-60 weeks. The results were as follow : 1. T-Chol almost unchanged. 2. HDL-C increased after 10weeks in two subjects and after 25weeks in five subjects. HDL-C/T-Chol ratio was simillar to HDL-C. These results suggested that the increase of HDL-C was possible in short period, but the decrease of T-Chol requires long period.

The purpose of this study is to analyze the electrolyte such as blood ph, Na^(+), K^(+), Ca^(2+), Mg^(2+), etc on the each stage of pre-exercise, post-exercise, each 5 minute-recovery, 10 minute-recovery & 30 minute- recovery after exercise. For this experiment, 14 male students at the department of athletics in B Information Technology college in Busan was classified into each 7 exercise group and 7 non-exercise group, and after training them on the intensity of 60%HRmax of each subject 3 period a week for 8 consecutive weeks, the experiment was carried out with the same condition as training manner in treadmill. The results of this study are as follows. 1. Change of Blood Ph Through Aerobic Exercise In exercise group and non-exercise group, there was no particular change in Blood Ph between rest before training & the rest after 8 week- training according to t test. In case of exercise group, after 8 week-training blood ph value was significantly decreased, and at the 30minute-recovery after exercise, ph value was recovered to the degree of rest (p<.001). In case of non-exercise group, blood ph indicated significant change as the similar tendency showed in exercise group, at 10 minute-recovery after exercise, blood ph was recovered to the degree of rest. (p<.001). The change of ph by period between exercise group and non-exercise group was not significantly different. 2. Change of Blood Electrolyte Through Aerobic Exercise 1) Change of blood Na+ through aerobic exercise In exercise group and non-exercise group, the change of Na^(+) between the rest before training and the rest after training was not significantly different according to the result of t test. In case of exercise group, after performing 8 week-training, Na^(+) value was significantly increased, and at 10 minute-recovery after exercise, Na^(+) value began to recover into the value in rest, and after 30 minute-recovery after exercise, Na^(+) value was recovered into the degree of rest (p<.05). In case of the change of Na^(+) in non exercise group, after exercise, Na' value was significantly increased in comparison with rest period, and at 5 minutes after exercise, it was recovered into the degree of rest. (p<.01). The change of Na^(+) by period between exercise group and non-exercise group was not significantly different. 2) Change of Blood K^(+) through aerobic exercise In exercise group and non-exercise group, the change of K^(+) in rest before training and the rest after training was indicated that there was no significant difference according to t test. In case of exercise group, after 8 week training, K^(+) value was significantly increased, and at 5 minute-recovery after exercise, K^(+) value was recovered into the value in rest (p<.05). K^(+) in non-exercise group was not significantly changed. 3) Change of blood Ca^(+) through aerobic exercise In case of exercise group, the change of Ca^(+) in rest before training and the rest after training was not significantly different according to the result of t test. In case of non-exercise group, the change of Ca^(+) in rest before training and the rest after training was significantly different according to the result of t test (p<.05). In case of exercise group, after 8 week-training, Ca^(+) value was significantly increased, and at 5 minute- ecovery after exercise, Ca^(+) value began to recover into the degree of rest, and after 30 minute-recovery after exercise, Ca^(+) value was recovered to the degree of rest (p<.01). In case of the change of Ca^(+) in non-exercise group, after training, Ca^(+) value was significantly increased in comparison with rest period, and at 30 minute-recovery after exercise, Ca^(+) value was recovered into the degree of rest. (p<.001). In case of the change of Ca^(+) by period between exercise group and non-exercise group, after exercise and at 5 minutes recovery after exercise, the change of Ca^(+) in non-exercise group is higher than that of exercise group (p<.01). 4) Change of blood Mgt^(2+) through aerobic exercise In exercise group and non-exercise group, the change of Mg^(2+) between rest before training and the rest after training was not significantly different according to the result of t test. In both cases of exercise group and non-exercise group, after 8 week- raining, the change of Mg^(2+) was not significantly different. The change of Mg^(2+) by period between exercise group and non-exercise group, after exercise, the change of Mg^(2+) of non-exercise group was higher than that of exercise group (p<.01). 3. Correlation Between Blood Ph and Electolyte Through Aerobic Exercise In performance of 8 week aerobic training, the result of correlation analysis between blood ph and electrolyte in pre-exercise, post-exercise, each 5 minute, 10 minutes, 30 minutes-recovery after exercise showed that in case of Na^(+), K^(+), Mg^(2+) did not have significant correlation, but in case of Ca^(2+), it showed significant negative correlation in pre-exercise and at 10 minute- recovery after exercise. (p<.05).

Four weeks old male rats of Sparague-Dawley were divided into three dietary groups (15%, 20% and 25% of dietary protein levels), and each dietary groups was further divided into sedentary and exercising groups. While the sedentary group of rats were housed in individual small cages all day long, the exercising rats were subjected to all day running and swimming at 30minutes per day. The influence of dietary protein level on the growth rate was studied. After three weeks of experimental period, the following results were obtained: 1. The body weight of sedentary group was significantly lower at 15% level of dietary casein than at both 20% and 25% levels. However, there was no significant difference between three levels. 20% level of dietary casein observed to produce most favorable in influence on maximum growth rate among three kinds of diets. 2. The body weight of exercising group was significantly higher at 25% level of dietary casein than at both 15% and 20% levels. However, there was no significant difference between three levels. Growth rate was higher in sedentary than in exercising rats, but there was a tendency that the casein level of exercising rats was higher than of sedentary rats.

The purpose of this study is to find out the effects of compound supplement vitamins E and C on the blood lipid levels during maximal exercise. Seven subjects are high school students and have to be taken 400IU of vitamin E and 200mg of vitamin C after breakfast during 8weeks, and maximal exercise before vitamin compound supplements and after 8weeks The results of this study are as follows: 1. In maximal exercise before and after taking vitamin E-C compound supplements, oxygen uptake (V02) and METs significantly (P<.01, P<.05) increased. Ventilation (CAE) also increased significantly (P<.05), while heart rate (HR) significantly (P<.05) decreased after vitamin E-C compound supplements. 2. TG was significantly (P<.05, P<.Ol) lowered before as well as after the maximal exercise. Total cholesterol (T-C) showed significant (P<.05) decrease after the maximal exercise. HDL-C indicated significant (P<.05) increase, but LDL-C presented reduction of significance (P<.05) before and after the maximal exercise. The LDL-C/HDL-C ratio significantly (P<.Ol, P<.05) decreased before and following the training. The T-C/HDL-C ratio also retained significant (P<.05, P<.Ol) reduction both before and after the running exercise. In conclusion, the compound supplements of vitamins E and C are considered to improve the respiro-circulatory function in exhaustive exercise, decrease an LDL-C concentration, increase an HDL-C concentration and prevent arteriosclerosis.

In order to elucidate the interrelationship between pre and post royal course triathlon (1km-swim, 30km-cycle, 9km-run) the investigation was undertaken to determine the enzymatic and hormonal response of plasma. 8 male of physical education students were participated in this study. Our results showed the following significant changes; In the post-triathlon a significant decreased body weight and %body fat were observed, as compared to the pre-triathlon. In the hormones, post-triathlon showed statistically significant increase in aldosterone(p<.01) and adrenaline(p<.05). Although noradrenline and dopamine concentration after race were slightly decreased, there were no significantly difference. Noradrenaline and dopamine concentration showed a moderate but slightly decrease. In the enzymes, the post triathlon race showed all statistically significant increase(p<.01). These result suggest that triathlon changes enzyme and hormone responses, that important factor of aldosterone are probaby involved in the regulation of urinary electrolyte excretions during triathlon. Further studies of triathlete are necessary to identify those phsiological parameter that are of successful triathlon performance.

The purpose of this present study was to investigate the effect of VitaminQ supplementation on antioxidant enzyme activities and cardiorespiratory function following prolonged exercise in trained triathlers. Male 14 healthy college students of trained triathlers participated in exercise sessions. The subjects were divided into 2 groups, as Non-supplement(NS) or VitaminQ supplement(VQ) groups. VitaminQ subjects were participated in two exercise sessions: an initial prolonged exercise(swim 750m, running 10㎞) and 70%V O2max treadmill running exercise. The Non-supplement group fed normal diet. VitaminQ group adminstated 90㎎/day for 4weeks. Venous blood samples were drown from the forearm antecubital vein pre-supplement, pre-exercise and immediately post-exercise. The results of this study can be summarized as follow: First, the SOD activity of RBC was not changed, while the GPx, GR or GR/GPx activies of Hb were significantly increased following prolonged exercise with CoQ10 supplementation. Second, 70%VO2max treadmill running exercise increased significantly the V O2max and VE, but the heart rate significantly decreased. In conclusion, the present results clearly show that the VitaminQ supplementation gave rise to increase the GPx or GR activies and to improve the cardiorespiratory function.

Effect of high intensive exercise on 8-hydroxy-2'-deoxyguanosine as a marker of oxidative DNA damage was evaluated in untrained volunteers. Fourteen male university students were randomly divided into two groups (maximal group n = 7, 80% HR group n = 7). The maximal group were performed a treadmill running at maximal until exhaustion and 80% HRmax for 30 min. who were performed a treadmill running at maximal and 80% HRmax for 30 min. The subjects had their peripheral blood and urine taken before and immediately after exercise. Plasma concentration of creatinine and purine metabolites increased significantly (p < .05) after 80% HRmax or maximal exercise. The urinary molar ratio of hypoxanthine to creatinine increased significantly, while those of xanthine and uric acid decreased significantly after intensive exercise. The 8-OHdG in lymphocytes increased, but 8-OHdG to creatinine ratio in urine decreased after maximal and 80% HRmax exercise. These results suggest that 80% HRmax exercise may induce higher oxidative DNA damages than maximal exercise.
