Purpose : This study was to investigate the effects of aerobic exercise and resistive exercise program on hypertension in the elderly. Methods : Subjects were allocated into one of three groups (aerobic exercise group, resistive exercise group, control group). Blood pressure was measured pre- and post-exercise in each exercise group. Data were analyzed with paired t-test and one-way ANOVA to determine blood pressure differences. Results : The results of this study were as follows. 1) The systolic blood pressure of the aerobic exercise group decreased significantly after exercise (p<.05). 2) The diastolic blood pressure of the resistive exercise group decreased significantly after exercise (p<.05). 3) There was a significant decrease in systolic blood pressure of aerobic exercise group compared with control group following the exercise. 4) There was no significant differences in diastolic blood pressure among three groups following the exercise (p>.05). Conclusion : Aerobic exercise and resistive exercise program were effective in reducing systolic blood pressure and diastolic blood pressure of the hypertension in the elderly. Thus, this program can be recommended as an effective intervention for the elderly. Therefore, regular and continued those exercises will be the solution for decreasing systolic blood pressure and diastolic blood pressure.

The purpose of this study was to find the effects of the eccentric exercise induced delayed muscle soreness on proprioception, muscle strength, muscle fatigue, and muscle pain of the elbow flexor muscles. Thirty one healthy male subjects were participated in this study. Before resisted eccentric exercise of the elbow flexors and immediately and at 1, 3, 5, and 7 days post-exercise, pain threshold, proprioception, tension tracking, initial median frequency, and fatigue index were measured. Pain pressure threshold and visual analog scale (VAS) was used to measure muscle pain. Proprioception of the elbow joint was measured by using 3 dimension motion analysis system. Maximum isometric contraction was measured by using digital tensiometer. Electromyography and power spectrum analysis was used to measure initial median frequency (IMF) and fatigue index (FI). Immediately post-exercise, a significant decrease pain threshold was observed that continued to 5 days post-exercise. VAS score was significantly increased at 1 and 3 days post-exercise compared to that of immediately post-exercise. Maximum isometric contraction, IMF, tension tracking ability of the exercised elbow joint were significantly decreased at 1, 3, and 5 days post-exercise compared to that of pre-exercise. FI was significantly increased at 1 and 3 days post-exercise compared that of pre-exercise. Proprioception sense of exercised elbow joint was significantly decreased immediately and at 1, 3, and 5 days post-exercise compared to that of pre-exercise. Proprioception sense of the contralateral elbow joint was significantly decreased immediately post-exercise compared to that of pre-exercise. However, proprioception sense that was measured in close chain kinematic position was not significantly difference between pre-exercise and post-exercise. These results could be useful to determine the resume time for exercising and participating sports activities.

This study was conducted to identify the effects of a planned exercise program based on Bandura's self efficacy model on metabolism, and the exercise compliance in type 2 diabetes mellitus patients. The study design was a nonequivalent pre-test post-test control design. Thirty four type 2 diabetes mellitus patients, who received follow-up care regularly through the diabetic out-patient clinic, were randomly sampled for this study. Twenty patients were assigned to the experimental group and fourteen patients were assigned to the control group. In the experimental group, a planned exercise program is composed of an individualized exercise prescription for 12 weeks, an individual education, and even a telephone coach program. In the case of the control group, they were instructed to continue with their usual schedules. The data collection period was from March 1999 to February 2000 Data were analyzed using SPSS/WINDOW 10.0 program. The results were as follows. 1. In the experimental group, the level of fasting blood sugar has significantly decreased from 188.20 mg/㎗ to 155.55 mg/㎗ after planned exercise program (F= 16.86, p=.000). For lipid metabolism, body fat per cutaneous decreased from 27.16% to 26.57% after planned exercise program. The score of self efficacy has increased from 64.20 to 66.65 after planned exercise program and it was statistically significant (F=4.850, p=.040) The functional vital capacity has increased from 3.28$\ell$ to 3.37$\ell$and it was statistically significant(F=7.300, p=.020). 2. In an after effect of a planned exercise program, 35 percent of the subjects who participated in a planned exercise program continued to exercise for another six months. In conclusion, the planned exercise program can improve cardiopulmonary function, glucose, and lipid metabolism. This program was show a positive effect on the self efficacy and exercise compliance.

This study was done to compare the effects of managing obesity using a behavior modification program and an aerobic exercise in adolescent girls. Thirty three subjects were selected from one girls' middle school located in Seoul. Seventeen girls participated in the behavior modification program by joining 60-90 minute group sessions weekly. The aerobic exercise program was given to 16 girls three times per week for 60 minutes each. These iterventions continued for eight weeks from October 17 to December 10, 1995. The data were obtained before and after the interventions by measuring degree of obesity, body weight, blood pressure, serum lipid, %body fat, and waist to hip ratio(WHR). Data ware analysed by using paired t-test. The results are as follows. 1. Subjects in both the behavior modification and the aerobic exercise groups showed significant decrese in the degree of obesity, body weight, diastolic blood pressure, total cholesterol, low density lipoprotein, %body fat and fat mass after the 8-week interventions. 2. Systolic bood pressure, high density lipoprotein cholesterol and waist to hip ratio were significantly decreased after the 8-week intervention in the behavior modification program group while triglyceride was significantly decreased after the 8-week intervention in the aerobic exercise program group. These findings indicate that both behavior modification and aerobic exercise programs are good strategies for managing obesity among adolescent girls.

This study was to determine the effect of exercise on the recovery of dopaminergic neuron loss and muscle atrophy in 6-OHDA-induced hemi Parkinson's disease model. Exercise was loaded twice per day for 30 minutes each time, at 5 days after 6-OHDA lesioning and continued for 16 days using a treadmill. Exercise significantly increased the number of tyrosine hydroxylase positive neuron in the lesioned substantia nigra and the expression level of tyrosine hydroxylase in the striatum compared with the control group. To examine which signaling pathways may be involved in the exercise, the phosphorylation of $GSK3{\beta}$ and ERK were observed in the striatum. In the control group, basal level of $GSK3{\beta}$ phosphorylation was less than in both striatum, but exercise increased it. ERK phosphorylation decreased in the lesioned striatum, but exercise recovered it. These findings suggest that exercise inactivates $GSK3{\beta}$ by phosphorylation which may be involved in the neuroprotective effect of exercise on the 6-OHDA-induced cell death. In the exercise group, weight, and Type I and II fiber cross-sectional area of the contralateral soleus significantly recovered and expression of myosin heavy chain and Akt and ERK phosphorylation significantly increased by exercise. These results suggest that exercise recovers Parkinson's disease induced dopaminergic neuron loss and contralateral soleus muscle atrophy.

Background and Objectives In designing a resistance exercise program, intensity, rest, and exercise volume are important. Many studies have been conducted to find the most suitable resistance exercise program incorporating the above, and in particular, many prior studies have been conducted on intensity. This study attempted to determine the effective volume of exercise by analyzing the number of repetitions performed at intensities of 65% one-repetition maximum (1RM) and 75% 1RM during the bench press exercise, and the electromyography (EMG) response of the agonist muscle. Materials and Methods Eight males in their 20s were selected as study subjects and they performed five sets of bench presses at two levels of intensity (65% 1RM, 75% 1RM). The following results were obtained by measuring the number of repetitions and the EMG response according to the exercise intensity and sets during the workout. Results First, the number of repetitions showed a sharp drop from the first set to the third set at 65% 1RM intensity and showed no change in the fourth and fifth sets. At 75% 1RM intensity, the intensity of hypertrophy showed a gradual decrease from the first set to the fifth set. Second, at 75% 1RM exercise intensity, the pectoralis major, anterior deltoid and triceps brachii showed high muscle activity, and the activity of the anterior deltoid continued to increase from the first set to the fourth set at 65% 1RM intensity, and from the first set to the fifth set at 75% 1RM. Conclusion It was found that during the bench press exercise, three minutes of rest at 75% 1RM intensity, five sets of five sets, one minute rest at 65% 1RM intensity, and three sets of the exercise were effective.

Purpose : The purpose of this study was to identify the effect of lumbar stabilization exercise (LSE) and isometric lumbar strengthening exercise (ILSE) on lumbar strength and lumbar extension range in healthy young adults. Method : Ten healthy young adults (six males and four females) volunteered to carry out the LSE and ILSE program for two weeks. The subjects were randomly allocated to two groups: the LSE group (n=5) and the LSE plus ILSE group (n=5). The LSE consisted of 20 minutes of exercise related to lumbar stabilization, and the ILSE was composed of five minutes of isometric stabilization exercise with a specific device. Each group exercised three times per week for two weeks. Assessment tools were made using the subjects' isometric lumbar strength and lumbar extension range before and after the interventions. Results : Statistical analysis revealed significant differences in isometric lumbar strength and the lumbar extension range between before and after the interventions in each group (p<.05). Also, the lumbar extension range improved significantly in the LSE plus ILSE group compared to the LSE group; however, there was no statistically significant difference in the two groups' isometric lumbar strength (p>.05). Conclusion : The findings suggest that ILSE might be feasible in clinical settings by offering benefits for lumbar function. Future studies will be continued.
