This study investigated the effect of physical training and oxidative stress on the anti oxidative activity and on plasma lipid profile. Forty eight rats were given either a physical training or no training for 4 weeks and were then subdivided into 3 groups: before-exercise (BE); during-exercise (DE); after-exercise (AE). The antioxidative activity was evaluated with the activities of catalase in plasma and superoxide dismutase (SOD), the ratio of reduced glutathione/ oxidized glutathione (GSH/GSSG) and the level of malondialdehyde (MDA) in liver. The plasma concentrations of triglyceride (TG), total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C)) were also compared. Compared to those of non-training group. catalase activities of training group were lower before exercise but higher during and after exercise. SOD activities were higher regardless of exercise. GSH/GSSG ratio was higher before exercise but was not significantly different during exercise and even lower after exercise. There were no differences between non-training group and training group in MDA levels regardless of exercise. Compared to those of non-training group, atherosclerotic index of training group was lower after exercise and there were no significant differences before and during exercise. There were no differences between non-training group and training group in HDL-C regardless of exercise. These results suggest that moderate physical training can activate antioxidant defenses and decrease the atherosclerotic index and this beneficial effect is evident under exercise-induced oxidative stress.

Purpose: The purpose of this study was to investigate the effect of exercise therapy and relaxation therapy on the level of ACTH and cortisol in workers and to determine, from this information, the effectiveness of applied exercise therapy and relaxation therapy as a nursing intervention method for workers experiencing stress. Method: The subjects were divided into an exercise therapy group. a relaxation therapy group, and a control group. The research design was a nonequivalent control group pretest-posttest design (exercise therapy : n=12. relaxation therapy: n=12, control group, the group without exercise or relaxation therapy: n= 12). The subjects in the exercise therapy group were given a particular intensity for each kp over 30 min, bicycle ergometer which uses the LX PE training system before and after four weeks of training. The subjects did 60-70% exercise intensity exercise therapy for eight weeks The relaxation therapy subjects were trained using a modified Jacobson's relaxation technique for eight weeks. The exercise and relaxation therapy groups were trained at the following intensity for eight weeks (3 times/week, 30 min/day). Changes in the levels of ACTH and cortisol were identified. Two-way ANOVA and multiple range test (SNK: Student Newman Keul) were used to examine the effects of exercise therapy and relaxation therapy at four and eight weeks. Result: 1. Changes in the level of ACTH in the relaxation therapy group were statistically significant at .05 level, and were better than that of the exercise therapy group after eight weeks. But there was no significant difference between the exercise therapy group and the control group. 2. Change in the level of cortisol in the relaxation therapy group were statistically significant at .05 level as compared to the exercise therapy group and the control group after four weeks, but not after eight weeks. Also, the relaxation therapy was statistically significant at .05 level after four weeks compared to before treatment, but there was a tendency toward increased cortisol after eight weeks. Conclusion: Relaxation therapy was found to be more effective in stress treatment than exercise therapy and as such is a desirable nursing intervention method for stress hormone reduction in workers.

Purpose: This study was designed to measure the effects of weight, abdominal girth, body fat, abdominal fat and cholesterol levels in combination with electrical stimulation, ultrasound and aerobic exercise on obesity and local lipolysis. Methods: Subjects were 30 obese adults who volunteered to take part in the experiment and had no physical diseases. They were randomly divided into three groups: (1) an aerobic exercise group (n=10), (2) an electrical stimulation group with aerobic exercise (n=10), and (3) an ultrasound stimulation group with aerobic exercise (n=10). Each experimental group went through 8 weeks of training. Results: All measured items including weight, girth of the abdomen, body fat, and cholesterol levels showed significant differences among groups. All three groups showed decreases for all items. The electrical stimulation + aerobic exercise group (group II) showed greater effects than the aerobic exercise group (group I) and the ultrasound stimulation group with aerobic exercise (group III). Conclusion: Electrical stimulation + aerobic exercise and ultrasound stimulation + aerobic exercise cause decreases in weight, girth of the abdomen, body fat and cholesterol level compared to aerobic exercise alone. These methods can be considered to be effective adjuvants to aerobic exercise in obese adults.

The purpose of the study was to identify the effects of a 12-week low-intensity exercise program on muscle strength, flexibility, balance, and cognitive characteristics related to the performance of activity of daily living(ADL). A total of 16 patients who were admitted to the medical unit of a general hospital in ChoongChung province were recruited, eight for the exercise group and eight for the comparison group. Four levels of low-intensity exercise from 'ROM on bed' to 'exercise while walking' were then applied to the exercise group according to their physical condition. During hospitalization, patients in the exercise group performed each level of the prescribed exercise with the researchers until they felt comfortable doing it independently. The researchers also visited the patients' homes after discharge to make sure they could perform the exercise with Theraband in their living environment. The exercise group was contacted by phone once a week to assess the frequency and intensity in which they performed the exercise as well as their physical condition. The subjects in the comparison group participated in measurements for the study without performing the exercise and were contacted by phone after discharge, in a matched time frame with the exercise group, to assess physical condition. Muscle strength, flexibility, balance, cognitive characteristics, and performance of ADL for the two groups were compared at the pretest and the posttest after the low-intensity exercise program by utilizing SPSSWIN and the results are as follows : 1) At the postest, measurements of muscle strengths showed that the strength of the dorsal flexor in the exercise group was significantly higher than in the comparison group. 2) Objective balance for the exercise group was significantly better than for the comparison group as measured by 'standing on one foot' and Tinetti gait and balance control. 3) The exercise group showed significantly higher task self-efficacy than the comparison group. 4) Perceived exertion for ADL for the exercise group was significantly lower than for the comparison group. 5) Improvement of performance of ADL without assistance was significantly higher for the exercise group than the comparison group. The findings suggest that a low-intensity exercise program would be useful for the elderly who show decline in their physical functioning due to hospitalization by partly improving physical strength, task self-efficacy, and performance of ADL. Directions for further research on issues of motivating people to exercise as well as of standardizing various types of exercise were discussed.

The purpose of this study focused how to show physiological responses comparing exercise group and non exercise group for progressive maximal wheelchair ergometer exercise loading in complete paraplegia. It also examined the various factors which would be influenced physiological responses. Sixteen subjects have been investigated in this study, and the subjects are divided into two groups as follows: 1) exercise group (7 subjects) 2) non exercise group (9 subjects). Each test was terminated by physical exhaustion and/or an inability to maintain a flywheel velocity. The results were as follows: 1) No difference was noted in pulmonary function test between two groups. 2) $\dot{v}$ Emax value during maximal exercise was significantly different between the groups (p<0.05). The mean $\dot{v}$ Emax of exercise group was $69.67{\ell}/min$, non exercise group was $41.47{\ell}/min$. 3) $\dot{v}$ $O_2max$(${\ell}/min$) value during maximal exercise was significantly different between the groups (p<0.05). The mean $\dot{v}$ $O_2max$(${\ell}/min$) of exercise group was $1.72{\ell}/min$, non exercise group was $1.15{\ell}/min$. 4) $\dot{v}$ $O_2$ max(ml/kg/min) value during maximal exercise was significantly different between the groups (p<0.05). The mean $\dot{v}$ $O_2max$($ml/kg{\cdot}min$) of exercise group was $25.99ml/kg{\cdot}min$, non exercise group was $18.61{\ell}/min$. 5) Maximal heart rate(HRmax) value during maximal exercise was significantly different between the groups (p<0.05). The mean HRmax of exercise group was 180.43 beats/min, non exercise group was 175.00 beats/min. 6) $\dot{v}\;E/\dot{v}\;O_2$ value during maximal exercise was not significantly different between the groups (p>0.05). The mean $\dot{v}\;E/\dot{v}\;O_2$ of exercise group was $36.36{\ell}/{\ell}\;O_2$, non exercise group was $45.46{\ell}/{\ell}\;O_2$. Considering the results which explore the exercise group with paraplegia has shown the maximal aerobic power compared with non exercise group, regular and consistent physical training is highly assumed as a main factor to improve cardiopulmonary fitness.

PURPOSE: This study assessed the exercise programs for improving the spinal angle and trunk flexibility by applying the aquatic exercise and sling exercise to young adults with scoliosis. METHODS: The subjects were 14 participants diagnosed with scoliosis. They were assigned randomly either to an aquatic exercise group (n=7) that received the WATSU exercise program or to a sling exercise group (n=7) that received a sling exercise program. The exercise program was 50 minutes once, three times a week, 12 times for four weeks. The spinal angle and flexibility were measured using the Cobb's angle and modified sit and reach test, respectively. Two variables were analyzed before and after the intervention, and the aquatic exercise group and sling exercise group were compared. RESULTS: After the intervention, the Cobb's angle decreased significantly, and the flexibility increased significantly in both groups (p<.05). A larger increase in flexibility was observed in the aquatic exercise group than in the sling exercise group (p<.05). CONCLUSION: These results showed that the two exercise programs improved the spine angle and flexibility. The increased flexibility showed that aquatic exercise was more effective than the sling exercise. Therefore, aquatic exercise and sling exercise can be used in the treatment and prevention of scoliosis.

Purpose: The purpose of this study was to determine the effects of group exercise, manual therapy, and a home exercise program on VAS (visual analogue scale), ROM (range of motion) of shoulder, and functional outcome in adhesive capsulitis. Methods: The study was conducted with 45 patients. All subjects were randomly assigned to 3 groups: group exercise (n=15), manual therapy (n=15), home exercise (n=15). The subjects performed an intervention program 3 times a week for 4 weeks a total of 12 times. Outcome measurements were VAS, ROM, and Constant-Murley score outcome measures. Measurements were taken four times, at baseline, 4 weeks later, 8 weeks later, and 12 weeks later. Results: VAS, ROM of the shoulder, and functional outcomes showed improvement in all groups at the final follow-up (p<0.05). VAS and ROM showed greater improvement with group exercise and manual therapy than home exercise, however, there were no significant differences between the two groups (p>0.05). Functional outcomes showed the greatest improvement in group exercise at the final follow-up. This improvement was greater than with manual therapy or home exercise (p<0.05). Conclusion: Group exercise and manual therapy were more effective for improving pain, ROM, and function than home exercise in adhesive capsulitis. In particular, group exercise is more effective in functional recovery than other physiotherapy interventions.
