  • This study was designed to find out the effects of aerobic exercise on lipid and Ca metabolism in seven healthy college women, aged 20 to 22 years. Metabolic studies were conducted before and after a 10-weeks exercise period, during which subjects participated in the planned aerobic dance program every day except Sunday. The initial mean time engaged in the exercise was 28 minutes and it was gradually increased up to 45 minutes around the middle point of the exercise period. During both of metabolic study periods, the subjects ate experimental diets which supplied about 120g of protein and 600mg of Ca daily and during the rest of the experimental period they ate their usual diets. The use of alcoholic beverages and drugs were prohibited. The results were summarized as follows. 1) The effect of exercise on lipid metabolism. (1) Mean body weight decreased significantly after exercise(p<0.01) and it did not show a significant decline in skinfold thickness and total body fat contents. (2) Serum total cholesterol level decreased significantly after exercise(p<0.05) and TG level also tended to be lower than that of pre-exercise period. Exercise did not exert any influence on the level of serum HDL-cholesterol in this study. (3) Exercise did not alter total lipid content in feces and apparent lipid absorption rate. 2) The effect of exercise on Ca and P metabolism. (1) After exercise, focal Ca excretion was slightly reduced, however, urinary Ca excretion was not significantly changed. In the results, a slight increase was shown in body Ca retention after exercise. (2) Exercise tended to increase urinary P excretion, but neither P balance nor fecal excretion was significantly changed after exercise. (3) Bone mineral content was not affected by exercise. In summary, aerobic exercise decreased total cholesterol and TG level in serum and tended to increase body Ca retention. With the results, it can be concluded that the additional physical activities beyond the normal daily life in college women might prevent some degenerative diseases-suchas atherosclerosis and osteoporosis.

  • This study was conducted to identify the effects of intake of beta-blocker and aerobic exercise on heart rate recovery (HRR) and exercise capacity after maximal exercise in acute coronary syndrome patients (ACS). Subjects were divided into 4 groups; Beta-blocker-Exercise group (n=10), Beta-blocker group (n=10), Exercise group (n=10), Control group (n=10). Symptom-limited grade exercise test were conducted on subjects pre- and post- 6 week study, to measure maximal heart rate, heart rate at 1 minute and 2 minutes at the recovery stage, maximal oxygen uptake and maximal exercise time. Study resulted in significant improvements in heart rate recovery for BB-Ex group ($17.40{\pm}5.58$ bpm to $26.10{\pm}6.66$ bpm), maximal oxygen uptake for BB-Ex group ($30.46{\pm}8.63$ to $36.33{\pm}8.10$) and Ex group ($29.04{\pm}4.93$ to $34.31{\pm}5.19$), and total exercise time for BB-Ex group ($906.30{\pm}158.57$ to $1018.50{\pm}151.21$), BB group ($805.70{\pm}182.94$ to $897.50{\pm}160.16$) and Ex group ($870.00{\pm}145.63$ to $961.90{\pm}107.29$). Therefore it showed the biggest improvement for heart rate recovery and exercise capacity in acute coronary syndrome patients when both Beta-blocker and aerobic exercise were in effect.

  • This research is aimed to prove if harmful effects of smoking, as the main reason for recently elevated blood vessel disease, could be reduced by aerobic exercise, and identify the positive effects of the aerobic exercise on smokers' blood vessel health(blood pressure, pulse pressure, and blood vessel elasticity. Experiments were performed on 40 male smokers aged between 40 and 55, which was equally divided into two groups of Aerobic Exercise Group (AEG) and Non Exercise Group (NEG). After measuring each group's blood pressure, pulse pressure, and blood vessel elasticity, AEG practiced aerobic exercise program for 50 minutes for each trial, three times a week, sustaining 12 weeks while NEG continued daily-life patterns without any special treatment. In 12 weeks, blood pressure, pulse pressure, and blood vessel elasticity of both groups were measured as the same way. As a result, the difference of systolic blood pressure between the two groups was not significant, while that of diastolic blood pressure was meaningful. The difference of pulse pressure between the two groups was meaningful, and that of blood vessel elasticity was also meaningful in all measuring points including left hand, right hand, left foot and right foot. As a consequent, it was found that aerobic exercise had positive effects on middle aged male smokers' blood vessel health.

  • Exercise can favorably influence brain plasticity by facilitating neurogeneration, neuroadaptivity, and neuroprotection. Aerobic exercise has been reported to change brain nerve growth factors (growth hormone, insulin like factor-1, estrogen and serotonin). The purpose of this study was to demonstrate the effects of aerobic exercise for 12 weeks on brain nerve growth factors in girls. Fourteen female participants in elementary school grades 1 through 3 were randomly allocated to the exercise group (EG, n=6) and control group (CG, n=8). The EG participated in 60 minutes of modified ballet exercise as aerobic training three days a week for 12 weeks. Based on comparison between groups by two-way ANOVA with repeated measures, aerobic exercise program participants experienced decreased weight (p<0.01), BMI (p<0.01), fat mass (p<0.001), fat percent (p<0.001) and increased LBM (lean body mass) percent (p<0.001). In addition, we detected that aerobic exercise decreased the level of serotonin (p<0.05) and increased the level of GH (p<0.05) and IGF-1 (p<0.05). These findings suggest that aerobic exercise programs can be an efficient intervention to change body composition, alleviate central fatigue, improve brain function, and induce brain cell proliferation in girls.

  • The purpose of this study was to analyze the effect of a 12 week aerobic resistance training circuit program on the health-related fitness, blood lipids, and cortisol in obese postmenopausal women. The subjects for the study were twenty obese postmenopausal women composed of the exercise group (n=10) and "no exercise" control group (n=10). The aerobic resistance training circuit program was conducted for 70 minutes 3 times a week for 12 weeks, in which the aerobic exercise consisted of 5 items each composed of 5 sets of aerobic exercise at 50-70% HRmax intensity for 1 minute for a total of 25 minutes and the resistance exercise consisted of 8 items conducted for a total of 25 minutes at 40-60% intensity of 1RM). In the exercise group, the body weight and BMI significantly decreased and the 20m shuttle run, sit-ups and sitting trunk flexion significantly increased. In the exercise group, the TC, LDL-C, and TG significantly decreased. Also, it was noted that the HDL-C was slightly higher in the exercise group than in the control group, but the difference was not statistically significant. The cortisol levels of the exercise group and control group at baseline were similar. However, after the aerobic resistance training circuit program, the exercise group had a significantly higher cortisol level than the control group. Therefore, regular and continuous aerobic resistance training was effective in improving the body composition, blood lipids and health-related fitness.

  • The purpose of this research is to analyze the effects of aerobic exercise on body composition, cardiopulmonary function, serum lipid level and antioxidants of obese and normal college female students. The subject group was made up of 13 normal students (below 30% body fat ratio) and 12 obese students (above 30% body fat ratio). After a pretest, the subjects were given an 8-week aerobic program. Then the subjects were given a posttest and analyzed of body composition, serum lipid level, antioxidants and cardiopulmonary function after the 6th and the 8th week of the program. The program schedule was made up of 4 days per week, 60 minutes per day. Test includes B.W., subscapular and triceps subcutaneous fat thickness, change of respiratory gas, and two blood sampling before treadmill exercise and post all out state, which analyzed serum lipid and antioxidants. The subjects performed treadmill exercise starting with 4km/hr of walking and then gradually increase the speed of 1km/hr per minute until all out state. The obtained data were analyzed using SAS program. The statistical methods employed here were one-way ANOVA with repeated measure, Duncan Multiple range test, paired-t test and t-test. The test results and conclusion of this research were as follows. 1. The effects of aerobic exercise on body composition were as follows ; Percent body fat was significantly reduced 6 weeks after the program and lean body mass was significantly increased 8 weeks after the program in both groups(obese group: F=3.44 P=.044, normal group: F=3.30 P=.048). subscapular skinfold of the obese group showed a remarkable decrease after the 6th week(F=4.33 P=.021) triceps skinfold of the normal group showed a remarkable decrease after the 6th and the 8th week(F=4.55 P=.017) compared with readings before the aerobic program, the aerobic program made a bigger difference concerning body fat, lean body mass, subscapular skinfold in the obese group than in the normal group(t=2.41 P=.024, t=2.40 p=.025, t=2.43 p=.028). 2. The effects of aerobic exercise on cardiopulmonary function were as follows ; Maximal $O_2$ uptake/kg was significantly increased 6 weeks after the program in the obese group(F=3.20 P=.054), but not much difference was observed in the normal group. Maximal pulse rate was significantly reduced in both groups after 6 weeks of the program(obese group: F=2.77 P=.087, normal group: F=7.17 P=.001). 3. The effects of aerobic exercise on serum lipid level were as follows ; In a resting period, total cholesterol, Triglyceride, and LDL-cholesterol were slightly higher in the obese group than in the normal group, but HDL-cholesterol was higher in the normal group. But, with the aerobic program, total-cholesterol, Triglyceride, LDL-cholesterol were reduced gradually and HDL-choleterol got increased in both groups, but not much change was noticed in the normal group. However, in the obese group, serum HDL-cholesterol level got increased significantly(F=5.12 P=.012). 4. The effects of aerobic exercise in serum antioxidants were as follows ; In a resting period, the obese group's serum Free Radical and GSSG content were higher than the normal group's and the normal group's serum GSH content was higher than the obese group's. After 6 weeks of the aerobic program, Free Radical was reduced significantly in both groups(obese group: F=13.87 P=.000, normal group: F=18.60 P=.000) In the obese group, 8 weeks after the program, GSH was increased significantly(F=13.78, P=.000). In the normal group, 6 weeks after the program, GSH was reduced but increased again after 8 weeks(F=6.07 P=.005). Plasma GSSG was significantly increased after 8 weeks of exercise in both groups(obese group: F=19.75 P=.000, normal group: F=22.42 P=.000,) Compared with readings before the aerobic program, the aerobic program made a bigger difference serum GSH in the normal group than in the obese group(t=3.37 p=.003). As this result shows, it is known that the regular aerobic exercise improves cardiopulmonary function, body composition, serum lipid effectively and through the serum Free Radical reduction and antioxidant system activation, oxidant stress was suppressed. This effect was higher in the obese group than in the normal one. At least 6weeks exercise period need for improvement of body composition, cardiopulmonary function and activation of antioxidant system. This result suggest that improvement of serum lipid profile was needed longer than 8weeks exercise period.
