Purpose: The purpose of this study was to understand the effect of aquatic exercise on balance and depression of stroke patients. Methods: For 12 participants with stroke, six members of the experimental group and six members of the control group were randomly selected and arranged. Proprioceptive Neuromuscular Facilitation (PNF) lower extremity aquatic pattern exercise was applied to the experimental group. On the other hand, participants in the control group performed PNF lower extremity pattern exercise on the ground. Both exercises were performed 30 minutes per day, five times per week, for a period of six weeks. Balance was assessed using the Berg Balance Scale (BBS) and Timed Up to Go test (TUG). Depression was measured using the Center for Epidemiologic Studies depression scale (CES-D). Results: As a result of comparison within groups, the experimental group showed significant difference for balance and depression after the experiment (p<0.05). In comparison between the two groups, the experimental group in which aquatic exercise was applied showed more significant change in balance and depression than the control group (p<0.05). Conclusion: According to the results of this study, aquatic exercise was proven to enhance the balance and decrease the depression of stroke patients.

Purpose: Generally, patients with stroke present with decreased balance and increased spasticity following weakness of the paralyzed muscles. Muscle weakness caused by stroke has two causes. This is caused by a decrease in motor output and an adaptive muscle change, resulting in muscle weakness and muscle paralysis. The purpose of this study was to investigate the effect of strengthening exercise on balance and spasticity in chronic stroke patients and to suggest the basis of clinical treatment. Methods: Twenty subjects were divided into two groups: a lower-extremity strengthening group (experimental group) and a general physical therapy group (control group). The sliding stander equipment was used for the experimental group and a regimen of warm-up exercise, the main exercise routine, and cool-down exercise were used for the muscle strengthening exercise program. Balance and spasticity were measured before and after the training period. Balance ability was measured by the Berg balance scale, the Timed up and Go test and the weight distribution of the paralyzed muscles by the Spacebalance 3D. Spasticity was measured by the Biodex system. Results: After the training periods, the experimental group showed a significant improvement in BBS, weight distribution of the paralyzed muscles, and decreased spasticity when compared to the control group (p<0.05). Conclusion: This study supported the hypothesis that lower-extremity strengthening exercise improves the balance and decreases the spasticity of stroke patients. If it is combined with conventional neurologic physiotherapy, it would be effective rehabilitation for stroke patients.

Objective: Nonspecific low back pain (NSLBP) is experienced worldwide by many age groups. Yoga is recommended as an exercise to reduce back pain and stress because it is a breathing exercise, posture, and meditation as key elements. The aim of this study is to compare the effects of yoga and stabilization exercise on pain intensity, function, and depression. Design: An open-label, parallel arm, randomized controlled trial Methods: Twenty-four participants were allocated to the experimental and the control group in a ratio of 1:1. Yoga (experimental group) and stabilization exercise (control group) were received twice a week for 6 weeks Participants were assessed at baseline and post-intervention for pain intensity (numeric pain rating scale), function (Aberdeen low back pain scale, flexibility,and strength), and depression (Beck depression inventory). Results: When the experimental group (Yoga) and control group (stabilization exercise) were performed twice a week for 6 weeks, numeric pain rating scale, Aberdeen low back pain scale, and flexibility in post-intervention showed significant improvement in both groups (P<0.05), However, in all variables, the experimental group showed a positive benefit compared to the control group (P<0.05). Conclusions: The results of this study show that yoga has more positive benefits compared to stabilization exercise in pain intensity, function, and depression in individuals with NSLBP.

Yu-Dong-Kong exercise is to produce heat from rubbing hands and is composed of 10 different types of exercise using warmed hands. The objective of this research is to evaluate the effect of Yu-Dong-Kong exercise on physical function and emotional state in elderly. The design of research is Nonequivalent Control Group Pretest-Posttest Design. The independent variable is Yu-Dong-Kong exercise, and the dependent variables are physical function and emotional state. Subjects are 18 elderly in the experimental group and 16 elderly in control group. All of them are above 60 year old and live in 1-city, Kyonggi-do. The exercise period was 4 weeks and data were collected from April to August in 1998. The exercise frequency was once a day. The exercise duration was from 10 to 20 minutes. The measurement tools are modified 1) Cornell Medical Index-Health questionnaire and 2) Geriatric Depression Scale. Collected data were analyzed by t-test and paired t-test based on the purposes of research using SPSS-Window package. The results are summarized as follows : 1. There was no difference in pre-exercise physical function between two groups (t=-.95, p=.35). 2. The hypothesis that 'physical function in the experimental group will be improved compared to the control group' was not supported by t-test(t=-.925, p=.362). However. the physical function in the experimental group showed much improvement than that in the control group. 3. The hypothesis that 'emotional state in the experimental group will be improved compared to the control group' was not supported by t-test(t=-1.715, p=.096). However, the emotional state in the experimental group showed much improvement than that in the control group. 4. The hypothesis that 'physical function will be improved in the post-exercise compared to pre-exercise' was not supported by paired t-test(t=.302, p=.766) However, a slight improvement in the physical function was found. For the further study, it is recommended to reevaluate the effect of Yu-Dong-Kong exercise through large number of subjects and long-term study. Also, a separate study with different type of subjects is recommended. In addition, continuation and compliance this strategy for exercise should be developed.

Purpose: This study is intended to examine the aquatic exercise on the improvement of muscle atrophy and motor function in an ischemic stroke model induced by middle cerebral artery occlusion. Methods: We used 60 Sprague-Dawely rats which were divided into 4 groups; the subjects were divided into group of 5 rats. Group I was a group of high dose aquatic exercise after inducing ischemic stroke; Group II was a group of low dose aquatic exercise after inducing ischemic stroke; Group III was a control group, Group IV was a sham group without ischemic stroke. Results: Muscle weight of gastrocnemius muscle was significantly difference in Group II compared to Group III on 8 weeks(p<0.05). For the changes in relative muscle weight of gastrocnemius muscle, there was significant increase in Group II compared to Group III on 8 weeks(p<0.05). For neurologic exercise behavior test, Group II generally had the highest score, compared to other groups. The results of behavior test that Group II improved in degeneration and inflammation of muscle fiber and decreased in destruction of nerve cells and cerebral infarction, indicating a similar state of muscle fiber and brain to Group III. Conclusion: Based on these results, aquatic exercise may improve muscle atrophy and contribute to the improvement of motor function.

This study was intended to examine the effects of electroacupuncture(EA) and therapeutic exercise on the improvement of exercise function, BNDF, and HSP70 protein expression in an ischemic stroke model induced by MCA occlusion. Experiments were conducted for 1, 3 days, 1, 8 weeks respectively. Group I was a group of EA and therapeutic exercise; Group II was a group of therapeutic exercise; Group III was a group of EA; Group IV was a sham group of EA; Group V was a control group; and Group VI was a sham group without ischemic stroke. In each group, neurologic motor behavior test, histologic observations, BDNF, and HSP70 expression were observed and analyzed. The following results were obtained. The results of behavior test suggest that 8 weeks after ischemic stroke was induced, Group I improved in degeneration and inflammation of muscle fiber and decreased in destruction of nerve cells and cerebral infarction, indicating a similar state of muscle fiber and brain to Group VI. In immunohistochemical observations, Group I showed increase in BDNF and decrease in HSP70. Based on these results, EA and therapeutic exercise may improve muscle atrophy and change in BDNF and HSP70 expression of ischemic stroke rats and contribute to the improvement of exercise function.

This study examined the effect of calcium supplementation and exercise on bone mineral density (BMD) and general characteristics, dietary intake and biochemical measurements for 45 healthy middle-aged women (40-57 years). Subjects were divided in to 4 groups; control group (G1), exercise group (G2), calcium supplementation group (G3), and calcium supplementation with exercise group (G4). The subjects were 45.8$\pm$ 0.66 years old. BMI(kg/$m^2$) was 23.31 $\pm$ 0.63 in Gl group, 22.92 $\pm$ 0.51 in G2 group, 23.64 $\pm$ 0.61 in G3 group, 23.40 $\pm$ 0.37 in G4 group, and BMI of all groups were in normal value. Energy intake was 1332.28㎉/day, 60% of RDA, so that may be unbalance of micronutrients. Especially, calcium intake was 62.8% of RDA that was very low level. Osteocalcine was not statistically significant but calcium supplementation group (G3) be showed increase. BMD was usually decreased by Aging, but in this study was increased in the all group, except control group. It showed increase of BMD for calcium supplementation and/or exercise. Overall results indicate that calcium supplementation and/or exercise increased BMD of middle-aged women, but long-term calcium supplementation and exercise will be able to more effect.(Korean J Nutrition 35(9) : 962~969, 2002)

This study was conducted to investigate the changes of exercise-induced stress response with acute anaerobic exercise in elite soccer players of university. The subjects were divided into elite soccer players of university (SG, n=10) and control group (CG, n=10). Subjects were tested three consecutive Wingate test for 30 seconds involving 2 times of 3 mins of resting time. In addition, whole blood and capillary blood were collected at rest, immediately post-exercise and 60 mins. of recovery time. Obtained results were as follows: Evaluated mean power and peak power of SG group was significantly higher than that of CG group in the all phase of Wingate test, respectively (p<.01). Although resting serum TG, TC, HDLC levels were not significant difference between SG and CG group, resting serum glucose of SG group was significantly lower than that of CG group. In addition, serum CRP levels of SG group were significantly lower than that of CG group at rest, immediately post-exercise and 60 mins of recovery time, respectively (p<.01). In serum cytokines, in spite of no significant differences in IL-1β levels between SG and CG group, IL-6 levels of SG group were significantly lower than that of CG group at immediately post-exercise and 60 mins. of recovery time, respectively (p<.05, p<.01). From these results, long-term combination training have a crucial role in amelioration of acute exerciseinduced stress response in elite soccer players.
