Purpose: This study was conducted to combine the effects of pulmonary rehabilitation program (PRP) on exercise capacity/tolerance and general health status of COPD patients based on the primary research results examined the effects of PRP, Method: Seventeen studies were selected by the sampling criteria established to include the studies that reported enough statistics necessary to conduct meta-analysis. Result: According to the study results, the most effective indicators for exercise capacity/tolerance were exercise time (such as cycling time or treadmill walking time) and ground walking distance within given time (6 minutes or 12 minutes), whereas effects on such indicators as VE and VO$_2$ were not statistically significant. PRP induced significant effect on patients' general health status, frequently measured by physical, psycho-emotional, and holistic indicators, the enhancement on psycho-emotional dimension resulted from PRP was more prominent than those of the other dimensions. From the results, it was noted that the place where PRP was given and the contents of PRP exercised their influence on the outcome variables. Which body part was trained was also one of the important factors that influence on the patients' perception of dyspnea during exercise as well as on exercise capacity/tolerance. Conclusion: PRP including exercise training significantly improved the exercise capacity and general health status of COPD patients.

Diabetic patients need exercise, diet and medication to keep normal glucose levels. Therapeutic exercise is good to control the glucose level and emotional stability. There are many studies to identify the relationship between them glucose drop and exercise load. However, there are few studies on exercise system that patients can easily calculate appropriate exercise tolerance at home and coaching exercise by individual. This paper presents simple exercise tolerance test and exercise coaching algorithm with indoor bicycle. We measure the change of glucose level before and after exercise. Then, the coaching program for the exercise is established by the proposed exercise tolerance test. From the simulation results, glucose levels were decreased after exercise for all experimental participants. The diabetics kept the lowered glucose level after 30 minutes of exercise.

The purpose of this study was to analyze the effect of acute forest walking exercise on blood glucose of IGT (impaired glucose tolerance), NIDDM (non-insulin dependent diabetes mellitus) in the elderly. There were four groups (n=60): forest walking exercise with IGT group (n=15; $66.21{\pm}4.16$ yrs), forest walking exercise with NIDDM group (n=15; $64.85{\pm}3.23$ yrs), field walking exercise with IGT group (n=15; $67.44{\pm}1.78$ yrs), field walking exercise with NIDDM group (n=15; $65.55{\pm}8.21$ yrs). They were tested on blood glucose levels at the beginning and at the end of each walking exercise. While the forest walking groups (interval + resistance exercise) worked for 40minutes with HRmax 50~60% level, the field walking groups (only aerobic exercise) worked for 40 minutes with HRmax 50~60% level. For data analysis, mean and standard deviation scores were calculated, and paired t-test and ANCOVA test were used. This study resulted in as follows. First, both walking groups showed the significant decrease of blood glucose in impaired glucose tolerance (IGT) after completing each exercise. Second, while the forest walking group showed the significant decrease of blood glucose in insulin dependent diabetes mellitus (NIDDM) after completing the forest exercise, the field walking group did not present any decrease of blood glucose in NIDDM after the field walking exercise. Therefore, the present findings suggest that the forest walking exercise as an interval and resistance exercise may be more effective to decrease blood glucose for IGT and NIDDM peoples in comparison to the field walking exercise as an aerobic exercise.

A great deal of attention has been paid to the quality of life in citizens due to the increased number of long term life expectancy. reported as effective in the health promotion of the senior citizens. In this study, the principal investigator developed an exercise program for the senior citizens, which could be educated and managed by nursing staff. This kind approach may support the need of exercise program on regular base via the social organization, which may mean the intentional change of life style. The exercise program consisted of exercise, health education, and a direct the population of the senior A regularexercise has been nursing care. A quasi -experimental study was conducted to investigate the effects of excercise program on health of the elderly in senior citizen's center. Independent variable was a 9 weeks exercise program. Dependent variables were: 1) physical health [e.g. physical fitness(cardiopulmonary endurance, back muscle strength, grip strength, muscular tolerance, flexibility and body fat proportion), physiologic parameters(blood pressure, pulse, respiration. and blood glucose), and perceived physical health status; 2) mental health measured by depression score; and 3) cognitive perception of exercise measured by usefulness and self-efficacy. A total of 37 subjects was randomly assigned into either the control group (without the exercise program: n=18) or the intervention group(with the exercise program: n=19). The results of the study analyzed using a SAS, were as follows: 1) In physical fitness of physical health, there was a significant improvement in cardiopulmonary tolerance. back muscle strength. muscular tolerance and flexibility in the intervention group, compared to the control group, while no difference in grip strength and body fat proportion. The exercise program resulted in decreases in blood pressure, pulse, respiration and blood glucose within normal range and improvement of perceived physical health status in the intervention group. 2) There was a slight increase of mental health(depression score) in the intervention group compared to the control group. but without statistical significance. 3) There was a significant improvement in cognitive perception of exercise(e.g. usefulness and self -efficacy) in the intervention group, compared to the control group. It was concluded that the exercise program employed in this study was appropriate for women senior citizens and had a positive effect on health in general.

Purpose: The purpose of this study was to identify the effects of a Progressive Walking program (PW) on physical activity, exercise tolerance, recovery, and post-operative complications for patients with a lung resection. Methods: A nonequivalent control group non-synchronized design was utilized and 37 participants with a lung resection (22 for control group, 15 for experimental group) were recruited at A university hospital from December 2012 to August 2013. The PW consisted of preoperative education, goal setting, and feedback, provided to the experimental group, and usual care to the control group. Data were analyzed using the SPSS WIN 18.0. Results: A higher proportion of patients in the experimental group showed adequate levels of physical activity (p=.001), shorter period of chest tube retention (${\leq}7$ days; p=.011), and shorter stay in the hospital (${\leq}10$ days; p=.036) than patients in the control group. Patients in the experimental group reported longer 6-minute walking distance (p=.032) and lower levels of dyspnea (p=.049) than patients in the control group. The PW did not influence the occurrence of pulmonary complications. Conclusion: The findings of this study suggest that the PW could be a useful strategy for improving patients' post-operative health and reducing cost after lung resection.

The purpose of this study was to investigate the effects of different types of exercise training on neurodegeneration and cognitive function in mice with impaired glucose tolerance (IGT). Thirty-six male C57BL/6 mice were randomly assigned to the control (CO, n = 9) and impaired glucose tolerance (IGT, n = 27) groups. The IGT group consumed 45% high fat diet for 4 weeks and received 40 mg/kg of streptozotocin twice in the lower abdomen to induce IGT. After the IGT induction period, the IGT group was subdivided into IGT + sedentary (IGT, n = 9), IGT + endurance exercise (IGTE, n = 9), and IGT + resistance exercise (IGTR, n = 9). The IGTE and IGTR groups performed treadmill and ladder climbing exercises 5 times per week for 8 weeks, respectively. Fasting glucose and glycated hemoglobin (HbA1c) levels were significantly higher in IGT group than in CO, IGTE, and IGTR groups (p < 0.05). HOMA-IR was significantly higher in IGT group than CO group (p < 0.05). Hippocampal catalase (CAT) was significantly lower in IGT group than in CO group (p < 0.05), while beta-amyloid ($A{\beta}$) was significantly higher in IGT group than in CO group (p < 0.05). Hippocampal tau was significantly higher in IGT group than in CO, IGTE, and IGTR groups (p < 0.05). The Y-maze test performance for cognitive function was significantly lower in IGT group than in CO, IGTE, and IGTR groups (p <0.05). These results suggest that IGT induces neurodegeneration and negatively affects cognitive function, while regular exercise may be effective in alleviating neurodegeneration and cognitive decline regardless of exercise type.

The purpose of this study was to investigate the effect of endurance and resistance exercise by using different intensity on diabetic-related blood profiles in impaired glucose tolerance mice. 54 C57BL/6 mice were divided into (1) Control group (CO, n=9), (2) impaired glucose tolerance group (IGT, n=9), (3) IGT + 50% of VO_2max endurance exercise group (IGT50A, n=9), (4) IGT + 75% of VO_2max endurance exercise group (IGT75A, n=9), (5) IGT +50% of 1RM resistance exercise group (IGT50R, n=9), 그리고 (6) IGT + 75% of 1RM resistance exercise group (IGT75R, n=9). Endurance exercise program was performed 40 min/day, 5 days a week for 8 weeks on treadmill. Resistance exercise program was consisted in ladder-climbing 8 set/day, 5 days a week for 8 weeks. After completed the exercise program, there was no different insulin level in the groups. The fasting glucose was significantly lower in CO than in other groups, and it was not different among the exercised groups. However, IGT75R was statistically lower than IGT. HOMA-IR was only different between CO and IGT. HbA1c was higher in IGT than in other groups. As compared with exercised groups, IGT 75A was lower than IGT50R. TC was lower in CO than in other groups, but there was no different in TG. Endurance exercise groups showed higher than CO and IGT in HDL-C level. LDL-C was lower in CO than other groups. In addition, IGT75A was lower than IGT and IGT50R in LDL-C level. In conclusion, 75% of 1RM resistance exercise had more positive effect on fasting glucose, and 75% of VO_2max endurance exercise improved HbA1c and LDL-C level. In addition, endurance exercise had more effective in HDL-C improvement as compared with resistance exercise.

Purpose: The purpose of this study was to identify the factors affecting shiftwork tolerance among nurses and provide basic data, ultimately, in formulating a plan for improving their shiftwork tolerance. Methods: The participants were 317 nurses who were working at three general hospitals in Daejeon and Seoul. Data analyzed t-test, ANOVA, correlation analysis, and regression analysis using SPSS 20.0 program. Results: As for the sub-areas of shiftwork tolerance for the respondents, more than a half of nurses working at shifts suffered from insomnia, felt drowsy, complained of chronic fatigue, and were at the anxious and depressed state. Shiftwork tolerance differed by the daily intake of coffee and exercise. Shiftwork tolerance was significantly positively correlated with sleep-wake habits, hardiness, and flexibility and negatively correlated with a languidity. Regression analysis revealed that shiftwork tolerance was affected by age, sleep-wake habits, languidity, flexibility, and hardiness. Conclusion: To put the results, nurses had shiftwork tolerance affected by sleep-wake habits, languidity, and hardiness. It is therefore necessary to make a scheme for allowing nurses to improve hardiness and flexibility and decrease the languidity with the objective of improving their shiftwork tolerance.

This research was conducted to study the effects of the supplementation of multi-extracts of mori folium (MF) and of exercise on plasma insulin and glucose levels in streptozotocin (STZ)-induced diabetic rats. Eight male Sprague-Dawley rats, 4 weeks old, were assigned to each experimental group and were raised in the laboratory for 10 weeks. The animal groups consisted of a normal-control group, a STZ-control group, 3 STZ-induced diabetic groups supplemented ad libitum with various amounts of MF extracts (MF-720, MF-360, and MF-180 groups), and a STZ-induced diabetic group supplemented with MF-360 along with exercise. In the normal-control group, glucose tolerance tests resulted in the peak blood glucose level being achieved in 15 minutes and a fasting blood glucose level being achieved in 60 minutes. In the STZ-control group, the peak blood glucose level was reached after 60 minutes and, even after 90 minutes, blood glucose shown at a significantly higher level compared to the fasting levels. In the groups supplemented with MF extracts, the blood glucose level peaked after 30 minutes of glucose challenge, and returned to the fasting level after 90 minutes; the MF-360 and MF-360+exercise groups showed the best levels of glucose tolerance. Blood glucose levels in the STZ-induced diabetic groups were significantly higher compared to the normal-control group. However, after 7 weeks of supplementation with MF extracts, a significant lowering of blood glucose levels was observed in all groups supplemented with the MF extract. The best effect was observed in the group given MF extract combined with exercise. Compared to the normal-control group, blood insulin levels were significantly lower in all STZ-induced diabetic groups; however, a significantly higher level of insulin was observed in the groups given MF extracts compared to the STZ-control group. This study shows that the supplementation of MF extracts in STZ-induced diabetic rats resulted in increased blood insulin levels and lower blood glucose levels.
