The object of this study consisted of two groups. One was the swimming exercise SD-Rat group, the other was the non-exercise SD-Rat group. Sample size was seven Rats repectively. Exercise period was ten week. Exercise group swimmed twenty minutes per a day and 5 times per a week. And then collecting blood from these two group's SD-Rats, making M Health center a request for a blood test on TC, TG, GOT, GPT, we come to a conclusion like below. The weight of the swimming exercise group has decreased 5.93% in comparison with non-exercise group. and has a significant difference(p<0.05). The liver weight of the swimming exercise group has decreased 7.83% in comparison with non-exercise group, and has not a significant difference. The TC of the swimming exercise group has decreased 39.22% in comparison with non-exercise group, and has a significant difference(p<0.05). The TG of the swimming exercise group has decreased 62.88% in comparison with non-exercise group, and has a significant difference(p<0.05). The GOT of the swimming exercise group has decreased 3.22% in comparison with non-exercise group, and has not a significant difference. The GPT of the swimming exercise group has decreased 16.14% in comparison with non-exercise group, and has a significant difference(p<0.05). In regard to above results, the regular swimming exercise therapy with dosage of high fat diet has an important role in healing and preventing a fattyliver, a hyperlipidemia, and an arteriosclerosis, intervening the lipid in blood.

Exercise physiology of fish was studied by means of Electro-cardio-gram(ECG) technique with wired electrode system. Effects of swimming activity on the heart rate change for carp Cyprinus carpio was observed and analysed under swimming speeds among 1~3 Body Length/s and swimming durations of 10 and 60 minutes in the flume tank. The heart rate increase during swimming activity was observed in higher speed and longer duration conditions. The exercise effect on the heart rate continued even after fish stopped swimming. The time for recovery after exercise was tended to be elongated with the higher exercise condition.

This study was intended to investigate the effects of regular swimming exercise and vitamin C supplementation on the antioxidant system following exercise stress. For the swimming exercise experiment, a swimming adaptation exercise of 1 week was given to a group of 6-week-old mice. Following this, a swimming exercise for 8 weeks was conducted. The experimental group was divided into 3: a control group (C), a swimming exercise trained group (T), and a group of swimming + vitamin C supplementation (TC: vitamin supplementation: 1.3 mg/l00 g diet). After the swimming exercise, these group were further divided into those that had received the exercise stress for 2 hours and those that had not experienced exercise stress group. Then, the activities of the superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) concentrations were measured. There was a lower weight increase in the T and TC groups than in the C group, and there was no significant difference between T and TC group. When exercise stress was not experienced, the activity of SOD was significantly increased in the TC group than in the T group, but there was no significant difference between C and T groups. The groups that had experienced a 2-hour exercise stress showed the SOD activity levels according to the following order, C < T < TC, with a significant difference between the three groups (p<0.05). There was no difference in MDA concentration amongst the experimental groups in non-exercise stress group. As well, there was no differences in MDA concentration between the C group and T group in the 2 hour exercise stress group. However, the TC group showed a MDA concentration level significantly lower than that of the T group. A significant increase in MDA concentration was observed in C group, when exercise stress was provided with no significant difference in the T and TC groups. As a result, regular exercise and vitamin C supplementation can be considered important in controlling the formation of lipid peroxides in exercise stress.

PURPOSE: The aim of this study was to compare the effects of different loading swimming exercises on muscle recovery after sciatic nerve crush injury in rats. METHODS: For this study, thirty-one Sprague-Dawley male rats were randomly divided into five groups. There were the negative control group (NCG, n=5), the positive control group (PCG, n=7), the low intensity swimming exercise group (LISEG, n=7), the moderate intensity swimming exercise group (MISEG, n=7) and the high intensity swimming exercise group (HISEG, n=5). Each rat was weighed to determine the lead weight to be attached to the base of its tail. Subsequently, the PCG, the LISEG, the MISEG and the HISEG were underwent standard unilateral sciatic nerve crush. The LISEG (no load), the MISEG (lead weight equivalent to 2% average body mass) and the HISEG (lead weight equivalent to 4% average body mass) were received the 10 minute swimming exercise in a day for 10 days. The NCG and PCG were not received with any therapeutic intervention. The diameter of the calf muscle and the level of serum lactate dehydrogenase (LDH) were measured to detect the effects of the swimming exercise. RESULT: The maximum diameter of the calf muscles was significantly increased after seventh swimming exercise in the LISEG, the MISEG and the HISEG compared with the PCG (p<0.05). However, there was no statistically significant difference between the LISEG, the MISEG and the HISEG. Also, the level of the serum LDH was significantly decreased in the LISEG, the MISEG and the HISEG compared with the PCG (p<0.05). CONCLUSION: Taken together, these results suggest that swimming exercise could accelerate muscle recovery processes after crush injury, but the different intensity of the swimming exercise does not affect healing processes.

The expression of c-Fos and c-Jun represents neuronal activity and plays a crucial role in the shaping of the development of brain. During the late pregnancy, exercise is known to influence neuronal activity of offspring. In the present study, the effect of swimming during pregnancy on the expression of c-Fos and c-Jun in the CA1, CA2, CA3 regions, and the dentate gyrus of the hippocampus of rat offspring was investigated using immunohistochemistry. Pregnant rats in the swimming group were forced to swim for 10 min once a day from 15 days after pregnancy until delivery. The expression of c-Fos and c-Jun in the CA1, CA2, CA3 regions, and the dentate gyrus of the hippocampus of pups was significantly increased by maternal swimming during late pregnant period. The present results show that prenatal swimming may enhance the neuronal activity of pups and affect the neonatal brain development.

Exercise-mediated physical treatment has attracted much recent interest. In particular, swimming is a representative exercise treatment method recommended for patients experiencing muscular and cardiovascular diseases. The present study sought to design a swimming-based exercise treatment management system. A survey questionnaire was completed by participants to assess the prevalence of muscular and cardiovascular diseases among adult males and females participating in swimming programs at sport centers in metropolitan regions of country. Using the Fuzzy Analytic Hierarchy Process (AHP) technique, weighted values of indices were determined, to maximize participant clarity. A patient management system model was devised using information technology. The favorable results are evidence of the validity of this approach. Additionally, the swimming-based exercise management system can be supplemented together with analyses of weighted values considering connectivity between established indices.

The aim of the present study was to evaluate the possibility of protective effectness of swimming exercise and Gastrodia elata blume oral administration against beta-cell damage in streptozotocin (STZ)-induced diabetes in rats. The animals were divided into five groups: the normal group(n=10), the STZ-induced diabetes group(n=10), the STZ-induced diabetes and moderate-intensity exercise group(n=10), the STZ-induced diabetes Gastrodia elata blume(300 mg/kg) oral administration group(n=10), the STZ-induced diabetes and moderate-intensity exercise and Gastrodia elata blume(300 mg/kg) oral administration group(n=10). Animals in the exercise groups were made to swim moderate swimming exercise protocols once a day for 4 consecutive weeks. Serum glucose concentration and insulin level, superoxide dismutase (SOD) and catalase (CAT) were measured in serum. Swimming exercise and Gastrodia elata blume extract administration has shown anti-diabetic effect probably through decreasing serum glucose and insulin level and increasing antioxidant enzyme activity.

The aim of this was to evaluate the effects of Rhus Verniciflua Stoke (RVS) extract powder on the endurance capacity for the forced swimming mice. Thirty mice were divided into 3 groups including negative control, 250 (RVS-250) and 500 (RVS-500) mg/kg RVS extract powder groups for 4-times swimming exercises. The swimming times to exhaustion in RVS-250 and RVS-500 mice were prolonged 1.6- and 2.0-fold at 4 weeks compared with negative control mice, respectively. Blood biochemical parameters for AST, ALT, T-CHO and TG were not significantly different between RVS fed or negative control mice. However, blood concentration of creatinine was significantly increased in RVS-250 mice, but not in RVS-500 mice. During the longer swimming exercise in RVS group, blood glucose and lactate levels were significantly decreased, but free fatty acid not changed. And also LDH levels were significantly decreased in RVS groups compared to negative control mice. Hepatic lipid peroxidation was not affected by RVS, but SOD and catalase activity were significantly increased in RVS groups. Interestingly, the levels of testosterone and free testosterone were significantly increased in RVS groups before swimming exercise, but they were not significantly changed among groups after swimming exercise. The present results suggest that RVS extract powders may enhance swimming exercise performance by recovering the exercise-fatigue via reduction of blood LDH activity and by burning blood glucose as an energy source. These results imply that RVS-produced testosterone may act as an energy buster to enhance physical activity.

Background: Aerobic training can be defined as any physical exercise that increases the heart rate and enhances the body's intake of oxygen long enough to benefit the condition of body. Running, cycling, and swimming are examples of aerobic activities. This type of exercise optimises immune functions. Recently several experimental findings suggested that the regular swimming training increase immune response, but there have been very few reports which compare warm water exercise with cold water exercise in spleen lymphocytes. Methods: This study was designed to examine the effects of regular swimming training on Index, the number of lymphocytes, proliferative activity and production of reactive oxygen species (ROS) by splenocytes in BALB/c mice. Thirty six mice (6 week old) were performed 10 weeks of regular swimming training and they were divided into 6 groups according to the regular swimming training (CRG: control resting group, CEG: control exercise group, WRG: warm water trained resting group, WEG: warm water trained exercise group, CORG: cold water trained resting group, COEG: cold water exercise group). Analytical items were weight change, spleen index, the number of lymphocytes, proliferative activity and production of ROS. All data were expressed as mean and standard deviation by using SPSS package program (ver. 10.0). Results: The swimming training significantly decreased body weight, and increased spleen index, the number of lymphocytes and proliferative activity in the presence or absence of Con A and LPS added conditions. For the WRG and CORG, the quantity of ROS from splenocytes was higher than CRG, whereas, ROS by spleen lymphocytes was lower following 90 min acute exercise stress. Conclusion: These results suggested that the swimming training not only increases the number of lymphocytes but also increases proliferative activity by splenocytes in vitro.
