Purpose: The aim of this study was to test the effects of passive exercise on upper extremities muscle spasticity, finger edema, and depression for chronic stroke patients. Methods: A non-equivalent pretest-posttest design was employed for this study. The subjects were 30 elderly patients who were hospitalized to treat chronic stroke. 15 patients were assigned to the experimental and control groups respectively. Passive exercise for 20 minutes per day, five days a week for 8 weeks (total 40 times) was provided for the experimental group. Outcome measurements included manual spasticity test to measure upper extremities' muscle spasticity, the ring measurement method for finger edema and the Korean version of Short-form Geriatric Depression Scale (SGDS-K) for depression. Results: The upper extremities' muscle spasticity (Z=-2.52 p=.012) and the degree of depression (F=5.56, p=.006) in the experimental group were significantly reduced compared to those of the control group. But the degree of finger edema did not significantly differ between the two groups (F=1.46, p=.240). Conclusion: Passive exercise for upper extremities should be encouraged for elderly patients with chronic stroke to enhance the upper extremities' functional capacity as well as depression.

Aging in mammals, including humans, is accompanied by loss of bone and muscular function and mass, characterized by osteoporosis and sarcopenia. Although resistance exercise training (RET) is considered an effective intervention, its effect is blunted in some elderly individuals. Fibroblast growth factor (FGF) and its receptor, FGFR, can modulate bone and muscle quality during aging and physical performance. To elucidate this possibility, the FGFR inhibitor NVP-BGJ398 was administrated to C57BL/6n mice for 8 weeks with or without RET. Treatment with NVPBGJ398 decreased grip strength, muscular endurance, running capacity and bone quality in the mice. FGFR inhibition elevated bone resorption and relevant gene expression, indicating altered bone formation and resorption. RET attenuated tibial bone resorption, accompanied by changes in the expression of relevant genes. However, RET did not overcome the detrimental effect of NVP-BGJ398 on muscular function. Taken together, these findings provide evidence that FGFR signaling may have a potential role in the maintenance of physical performance and quality of bone and muscles.

This study evaluated the effects of D-ribose supplementation on exercise time in a hypoxic chamber. Eight healthy young males participated in experiments under all four different conditions; placebo+normoxic, placebo+hypoxic, ribose+normoxic, and ribose+hypoxic. Subjects took 1 g per 10 kg body weight of ribose dissolved in drinking water 30 minutes before and immediately before running. We observed the run-to-exhaustion time, the maximum heart rate, and the changing pattern of the heart rate during exercise. The longest running time was achieved when subjects ran under normoxic condition with ribose supplementation. The shortest running time occurred when subjects ran under hypoxic conditions without ribose supplementation. We measured MDA and GPx to determine any changes in oxidative stresses or antioxidative systems. MDA was affected by the environmental conditions and the running time. The activity of GPx showed a significant difference only with the different environmental conditions of exercise. The results of this study indicate that ribose can be considered a possible ergogenic during exercise in specific conditions, but more detailed and well-controlled studies are needed to make a definitive conclusion.

Purpose: This study aimed to assess the effect of rowing ergometer training on the aerobic capacity and strength of male high school students over a 12-week period. Methods: Fourteen high school students volunteered to participate in the study. The subjects were divided into two groups: seven subjects in the experimental group and seven in the control group. The subjects in the experimental group performed rowing ergometer training for 75 min per session at three days a week for 12 weeks. The exercise intensity set the maximum heart rate (HRmax) from 40% to 80%. Aerobic capacity was measured by ventilation, cardiac output, and oxygen intake per body weight. Strength was measured by grip strength and back strength before and after training. Results: A significantly increased ventilation (p=0.01), cardiac output (p=0.01), and oxygen intake per body weight (p=0.00) were found in the experimental group. A significantly increased grip strength in the right and left hands (p=0.00, 0.00) and back strength (p=0.04) were observed in the experimental group. Conclusion: Rowing ergometer training can be an effective combined exercise for aerobic capacity and strength of high school students.

Purpose: The purpose of this study was to examine the effects of Danjeon Breathing Exercise (DBE) on vital capacity, physical fitness, anxiety and depression among older adults. Methods: This study employed the nonequivalent control group pretest-posttest design. The experimental group participated in a 12-week DBE program. Vital capacity and physical fitness were measured with a health measurement system (HELMAS). Anxiety and depression were measured with SCL-90-R-K. Data were collected from 37 community-dwelling older adults (experimental group=21, control group=16) in the Seoul metropolitan area. The data were analyzed by $x^2$-test, Mann-Whitney test and ANCOVA. Results: The experimental group taking DBE reported significant increases in flexibility than the control group, but differences in vital capacity and balance were not significant. Older adults taking DBE showed significant decreases in the anxiety and depression levels. Conclusion: A DBE program may be a useful nursing intervention for older adults to improve their flexibility and to reduce anxiety and depression.

The present study investigated the effects of Hovenia Dulcis (HD) fruit extract powder on the improvement of physical activity, especially exercise capacity. Forty mice were divided into 4 groups including normal controls, negative controls, 100 (HD-100) and 200 (HD-200) mg/kg HD fruit extract powder groups for 5-times exercises using treadmill. Normal control did not performed treadmill running but others did 5-times for 10 days. HD fruit extract powders were administrated orally one-times per day for 10 days before treadmill exercise and normal and negative controls were fed with excipient water. After 5-times exercise, blood biochemical analysis showed that aspartate aminotransferase (AST), lactate dehydrogenase (LDH) and creatine phosphokinase (CK) activities and blood lactate concentration were statistically increased in negative controls than in normal controls. They were decreased in HD fruit extract powder groups, compared with negative controls. These results were considered as the effects of HD fruit extract powders on reduced tissue damages during exercise. Other measured indices did not reveal remarkable differences. All together, these results suggest that HD fruit extract powders may enhance the exercise performance by recovering the exercise-fatigue via blood lactate concentration by reducing blood LDH activity and via reduction of blood CK and AST activity.

To evaluate training effect, aerobic dance was performed by eight female collegestudents for 8 weeks. Body composition, cardiopulmonary function at rest and during maximal exercise, blood cholesterol concentration at rest were determined before and after 8weeks of aerobic dance training. Maximal exercise was performed on the treadmill according of Bruce protocol. Pre to post training differences were evaluated. The results obtained were as follows : 1. After the training, skinfold thickness and total body fat decreased significantly(p＜0.1) while lean body mass increased with significance (p＜0.1). 2. Heart rate and arterial blood pressure at rest decreased without sinificance after the training. 3. As a result of training, forced vital capacity and forced expiratory volume for a second increased significantly (p＜0.01, p＜0.1). 4. After the training period, heart rate at 3, 6, and 9 min. during treadmill exercise was significantly lower than those of pretraining (p＜0.05). 5. After the training, systolic and diastolic blood pressure at 6 and 9 min during the exercise was significantly lower than those of pretraining (p＜0.025, p＜0.1). 6. After the training, oxygen uptake at 3 and 6 min during the exercise was significantly greater than those of pretraining (p＜0.05). 7. As a result of training, the maximal oxygen uptake increased significantly during the exercise (p＜0.1). 8. After the training, expired air volume for a minute at 3 and 6 min during the exercise was signigicantly grerter than those of pretraining (p＜0.1). 9. After the training, repiratory quotient during the exercise was lower than pretaining without significance. 10. After the training, blood HDL -cholesterol concentration incereased with significance, (p＜0.1) blood total cholesterol and triglycerids concentration decreasedsignificantly (p＜0.1). From these results, it may be concluded that 8 week aerobic dance training reduces skinfold thickness and body fat contents, improves the cardiopulmonary function and tissue oxygen utilization, reduces blood cholesterol and triglyceride concentration and brings about the increase of blood HDL-cholesterol concentriation.

PURPOSE: The purpose of this study was to investigate whether a circuit aerobic exercise program positively affects pulmonary function and gait endurance in chronic stroke patients. METHODS: Twenty-four chronic stroke patients were allocated equally and randomly to an experimental group (n=12) or a control group (n=12). All participants received 60 minutes of comprehensive rehabilitation treatment, the experimental group additionally performed a circuit aerobic exercise for 30 minutes, while the control group additionally performed a general aerobic exercise, i.e., gait training on the treadmill for 30 minutes. These 30-minute exercise sessions were held three times per week for six weeks. Pulmonary function was assessed using forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and maximal voluntary ventilation (MVV), and gait endurance was assessed using the 6-minute walk test (6MWT). RESULTS: In the both groups, FVC, FEV1, MVV, and 6MWT were significantly increased after training. Members of the experimental group showed significant improvements in FVC, FEV1, and MVV, and significantly greater improvements than controls (p<.05). However, 6MWT improvements were not significantly different in the two groups (p>.05). CONCLUSION: The devised circuit aerobic exercise program offers an effective rehabilitation aerobic exercise for improving pulmonary function and gait endurance in patients after chronic stroke.

Background: Physical exercise during leisure time is known to increase physical capacity; however, the long-term effects on work ability and work strain are inconclusive. The aim of this study was to investigate the effects of a 6-month physical exercise program on work ability and work strain after 6 months and 30 months, among women with menopausal symptoms at baseline. Methods: A questionnaire including questions on work ability and work strain was mailed in the beginning, at 6 months and after 30 months after the intervention to occupationally active women participating in a randomized controlled study on physical exercise and quality of life. The intervention included aerobic exercise training 4 times per week, 50 minutes per session. Work ability was measured with the Work Ability Index (WAI) and with questions about physical and mental work strain. Results: Women aged 47-62 years (N=89) who were occupationally active at baseline were included in the analyses. The increase in WAI from baseline to the end of the exercise intervention (6 months) was statistically significantly greater among the intervention group than among the control group (regression coefficient 2.08; 95% confidence interval 0.71-3.46). The difference between the groups persisted for 30 months. No significant short- or long-term effects on physical and mental work strain were found. Conclusion: A 6-month physical exercise intervention among symptomatic menopausal women had positive short-term as well as long-term effects on work ability.
