To investigate blood pressure and body fat, cholesterol, triglyceride concentration and relationship of each other in Korea adults, total 382(men 188 and women 196) aged between 20-69 years were chosen as subjects. The results are summarized as follows. 1. Body fat was increase with diastolic blood pressure from 60-69mmHg group to 110-130mmHg group in men and women. Body fat in women was always more than in men all range of blood pressure. 2. Triglyceride concentration was significantly increases with blood pressure in men. In women, triglyceride concentration was significantly increase over 90mmHg regarded as hypertension. 3. Total cholesterol had no relationship to blood pressure, but total/HDL cholesterol ratio tended to increase with blood pressure. Both men and women, high density lipoprotein cholesterol was decrease and low density lipoprotein cholesterol was increase with blood pressure. 4. The factor which had the best relationship to blood pressure was body fat in men and triglyceride in women. The total/HDL cholesterol ratio had higher correlation coefficient than HDL or LDL single value. From the above results it is speculated that body fat and triglyceride, cholesterol concentration responsible for hypertension. Especially high blood pressure has relation to body fat in men and triglyceride in women. And body fat, blood triglyceride, cholesterol concentration are concerned with each other, but the relationship is not high.

In an effect to analyze various factors of pulmonary functions caused by the before and after treadmill exercise showing the decrease of some values such as FEV1.0sec value, PEF and FEF25%-75%, subjects were selected from a group consisting of 20 males and 22 female, ranging from the age group of 30 to 60, who has not been engaged in any physical exercise in their daily life and dignosed as Exercise-Induced Asthma patients. Major findings and conclusion are as follows : 1. After treadmill exercise, both male and female showed significant differences in FEV1.0sec(p<0.05) in analyzing the change of pulmonary functions caused by the decrease of FEV1.0sec value. The male showed significant differences in FVC and FEV0.5sec, while the females showed significant differences in PEF, compared with their before exercise. 2. After treadmill exercise, the male's PEF decrease significantly affected other values related to the pulmonary functions. Both male and females showed statistically significant differences in PEF and FEF2.5%(p<0.01), as well as in MVV(P<0.01). And the male showed significant decrease in FVC, FEV0.5sec whilest there were significant decrease in the female in FEF50%, FEF75%(p<0.05) and FEF25%-75%(p<0.01), compared with their before exercise. 3. As for the change of pulmonary function caused by the decrease of FEF25%-75% after treadmill exercise, both males and females showed significance differences in FEF25%, FEF50% and FEF25%-75%(p<0.01). The female showed a significant difference in PEF(p<0.05).

The purpose of this study was to investigate the effect of treadmill exercise programs on cardiopulmonary functions and serum lipids in adult obesity men. The subjects consisted of 33 obese adults between 30 and 70 years old and all of them had no other complications. Subjects participated in treadmill exercise programs for 12 weeks according to the exercise prescriptions. They started to exercise for 20 minutes per day, six times a week at 50% of maximum O_2 consumption (V˙O_2max), and later exercised for 50 minutes at 80% of V˙O_2max, which was the maximum exercise intensity of the program (Exercise intensity has been increased gradually). The changes of body composition, serum lipids, and cardiopulmonary functions in the subjects before and after the treadmill exercise program have been measured. The results are as follows. 1. Body weight, percent body fat, and fat body weight were reduced(p<0.05, p<0.01), and body fluid were increased after exercise programs(p<0.01). The group below 50 years old and above 25% of body fat showed more decrease in body weight and percent body fat, and more increase than that above 50 years old below 25% of body fat. 2. Resting heart rate, systolic and diastolic blood pressure were significantly reduced after exercise programs(p<0.05, p<0.01), but these parameters decreased approximately same for the groups of ages and percent body fat. 3. Vital capacity, forced expiratory volume for 1 second percent and maximal voluntary ventilation were increased after exercise programs. The group below 50 years old and above 25% of body fat showed more increase than that above 50 years old and below 25% of body fat. 4. Total cholesterol, LDL cholesterol, total cholesterol/HDL cholesterol rate and triglycerides were reduced (p<.05, p<0.01), and HDL cholesterol levles were increased after exercise programs. The group below 50 years old and above 25% of body fat showed more decrease in total cholesterol, LDL cholesterol, total cholesterol/HDL cholesterol rate and triglycerides, and more increase than that above 50 years old and below 25% of body fat. 5. Heart rate increase during exercise were reduced after exercise programs. The group below 50 years old and above 25% of body fat showed more decrease than that above 50 years old and below 25% of body fat. 6. Blood pressure increase during exercise were reduced after exercise programs. The group above 25% of body fat showed more decrease than that below 25% of body fat. 7. Oxygen uptake of during exercise were increased after exercise programs. 8. Maximal oxygen uptake were significantly increased after exercise programs (p<0.01). 9. The regression equations between heart rate, systolic blood pressure, and oxygen uptake were obtained. These correlation coefficients of the post-programs showed higher that those of pre-programs. In this study, the treadmill exercise programs suitable for the obese was developed and applying this programs weight, percent of body fat, body fat weight, and serum lipids levels ere reduced. Thus cardiopulmonary functions was improved. The group below 50 years old and above 25% of body fat showed more decrease than that above 50 years old and below 25% of body fat. It is to be noted that both systolic blood pressure and oxygen uptake can be estimated by heart rate only using the regression equations.

To study the effects of exercise stress test in lifestyle activity on blood components and exercise capacity in elderly. 78 man, who where 50-60 years old, were checked by medical process and exercise stress test. Subjects were divided into three groups by lifestyle physical activity that were high active group, low active group and control group. Results of this study are following. In percent body fat, it was showed significant difference among the three groups(p<0.01). In blood components of WBC, it was not significant difference among the three groups, but RBC was showed significant difference high active group and low active group, high active group and control group(p<0.01). In hemolobin, it was not significant difference among the three groups, but hematocrit was showed significnat difference high active group and control group(p<0.01). In serum lipid of total cholesterol, values of high active group were significantly lower than low active group and control group(p<0.01). In triglycerides, values of high active group were significantly lower than low active group and control group(p<0.01). In HDL-C, values of high active group were significantly higher than low active group and control group(p<0.01). In LDI-C, values of high active group were significantly lower than low active group and control group(p<0.01). Every groups showed a significant increase in heart rate one minute of exercise, gardual increase in heart rate during the three minute of exercise, increase in heart, rate of control group was higher than that of other groups nine minute of exercise. The systolic blood pressure control group both at rest and during exercise was higher that of high active group and low active group. In oxygen uptake(V˙O_2). rest was showed significant difference in high active group and control group(p<0.05). In peak exercise, values of high active group were significantly higher than low active group and control group(p<0.01). In recovery one minute, values of high active group were significantly higher than low active group(p<0.01), but showed rapidly recovery in two, three minute. From this study, control group was appeared very high risk on modern degenerative disease of a heart disease, abnormal lipid metabolism, coronary artery disease, and arteriosclerosis by high body fat, serum lipid components. Conclusionally, elderly man must increase their activities and leisure active in daily life for improving protecting degenerative disease.

In order to study the effects of myocardial oxygen uptake and electrocardiographic ST segment at exercise stress testing in hypotension group, 26 men who aged 40-50 years were checked by medical process and exercise stress testing. Subjects were divided into the 2 groups that were control and hypotension. Statistical analysis was performed using analysis of variance t-test. In results, myocardial oxygen uptake(MVO_2) was showed no significant difference in two groups. However, ST segment(V_5 ST level, V_5 ST slope) of hypotension group was showed significantly higher(a double number) then that of control group. Conclusionally, A statistically significant improvement was noted with genuflection contraction, leg crossing, and thigh contraction after three and four 45minute sessions. Possibly, the combination of aerobic exercise activity, biofeedback, and resistance training may further augment the value of physical activity.

The purpose of this study was to investigate the effects of cardiovascular system factors and isokinetic muscle strength on percent body fat in youth hypertension groups. Sixteen youth hypertension men, ranged in age from 20-25 years, were divided into two groups: normal group(body fat<20%, n=8) and obesity group(body fat>20% n=8). The methods to examine cardiovascular function and muscle strength testing, such as heart rate, blood pressure, myocardial oxygen uptake, oxygen uptake per body weight and isokinetic muscle testing have all provided further evidence for obesity in hypertension. During exercise heart rate was no significant difference between two groups. but maximal heart rate of obesity group is 159.25beat/min, that is significantly lower than normal group(168.50 beats/min) (p<0.05). During exercise systolic blood pressure was significantly higher in obesity group compared with normal group(p<0.05). Maximal SBP of obesity group is 210.0mmHg, that is significantly higher than normal group(202.25mmHg) (p<0.05). Maximal DBP of obesity group is 102.0mmHg, that is significantly higher than normal group(91.5mmHg) (p<0.05). During exercise rate pressure product was significantly higher in obesity group compared with normal group(p<0.05, 0.01). Maximal oxygen uptake(V˙O_2max) was no significant difference between two groups, but at recovery 2, 3 minute, obesity group was significantly higher than normal group(p<0.05, 0.01). During exercise ST level in lead V_5 of obesity group is significantly higher than normal group(p<0.05, 0.01). Isokinetic muscle strength were slightly higher in the above obesity group than in the normal group. In 180°/sec left flexor, obesity group was significantly higher than normal group(p<0.05). Conclusionally, youth hypertension men must increase their aerobic activities and proper diet(decrease caffeine, salt, et.) for improving their cardiovascular system factor and protecting modern disease, especially recovering from degenerative disease.

To study the effect of weekly calorie expenditure by aerobic exercise on %Body Fat and plasma lipoprotein. 141 women who were 40∼60 years old were selected. Physical activity questionnaire, resting medical process and exercise stress test were performed. %Body Fat of the high energy expenditure group(more than 2.363±647kcal/week) was lower than non exercise group. Plasma Lipoprotein(TC, Tg, LDL-C) of the group(more than 1.275±236kcal/week) was lower than non-exercise group. But HDL-C was not significant difference by the energy expenditure. It was more effective to analyse regression of the plasma lipoprotein by the week-energy-consumption/%Body Fat than by the weekenergy-consumption alone. From this study, the limitation of exercise quality is more than 1.275±236kcal/week for improve the plasma lipoprotein. But, the limitation of energy consumption is required more than 2363±647kcal/week for improve of %Body Fat and HDL-C.
