In this study, the absolute and relative strength of six upper extremity resistance exercises were measured by classifying resistance exercise experts and non-experts. As a result, the skilled group showed higher absolute and relative muscle strength than the unskilled group in the 6 upper extremity resistance exercises. These results are judged to be the hypertrophy of fast-twith muscles, the mobilization of motor units, and the increase in the speed of nerve conduction while the skilled person consistently performs resistance exercise. Experts use intermuscular coordination efficiently to stably perform the load according to the movement and exercise intensity performed during exercise, whereas the inexperienced person uses relatively large muscle groups rather than efficiently using intermuscular coordination. It is considered that exercise motion and load were performed by mobilizing. In addition, as a result of comparing the absolute and relative muscle strength between the 6 types of upper limb resistance exercises, there was a difference between the 6 types of upper limb resistance exercises in the two groups. It can be judged that greater muscle strength and endurance were created through liver coordination.

Purpose: The purposes of this study were to compare the motivation for health behavior, health behaviors practices, and ADL of institutionalized elderly women with those of non-institutionalized elderly women. Methods: A cross-sectional descriptive survey was conducted in convenience samples of 144 aged women(80 institutionalized and 64 non-institutionalized) using structured questionnaires. Descriptive statistics, $x^2$-test, and ANCOVA were used for data analysis with SPSS program. Results: The institutionalized elderly reported significantly higher motivation than the non-institutionalized elderly. In subcategories of motivation, self-efficacy of the institutionalized elderly was significantly lower than that of the non-institutionalized elderly. The non-institutionalized elderly reported significantly lower perceived benefits and significantly higher perceived barriers than institutionalized elderly. The institutionalized elderly reported significantly lower health behaviors in exercise and nutrition than the non-institutionalized elderly. Among health behaviors of the non-institutionalized elderly women, stress management marked the lowest score. Conclusion: To enhance motivation of institutionalized elderly women, interventions for building self-efficacy are needed. To promote the health behavior of the non-institutionalized elderly, stress management programs are needed. All elderly women need exercise.

This study was aimed to investigate whether abdominal obesity is associated with non-insulin dependednt diabetes. The distribution of body fat patterns was observed in 181 female patients with diabetes, aged 33 to 83 years, living in the Taegu area, Korea. The following anthropometric measuremetns were made on all participants from October 1 to November 25, 1991 : weight, height ; waist and hip circumferences in standing position. The waist hip circumference ratio was used as an index of abdominal obesity. The results were as follows; 1) The mean fasting blood glucose of diabetic subjects was 145$\pm$50.3mg/dl and the mean duration of diabetes was 4.7$\pm$7.5 years. 2) Obese subjects above the ideal body weight body weight of 120% in the investigation are presently 52%, but 63% of subjects were reported to be obese in the past. The mean BMI of the subjects is 24.57$\pm$3.15 and the past mean BMI was 27.13$\pm$3.26. One year after reaching their highest body weight, 47% of the subjects developed diabetes. Two years after reaching their peak body weight, 74% of diabetic subjects developed diabetes. 3) Using the waist-hip circumference ratio, subjects beloing to the upper body obesity(WHR>0.84) were 65.5%. 4) The average daily energy intake did not differ between the obese and non-obese diabetic subjects, whether they were assessed with BMI or with RBW. 5) The average daily energy intake was higher in the upper body obesity subjects than in the lower body obesity subjects. 6) Diabetics withing the regular exercise group had lower fasting blood glucose levels than the non-regular exercise group. Exercise did not effect the RBW, BMI, and WHR. 7) The waist-to-hip circumference ratio correlated significantly in positive with waist-circumference, but did not correlated with hip-circumference. Therefore, WHR may depended on the increased accumulation of abdominal fat in female diabetics. In conclusion, these findings suggest that caloric intake is more associated with abdominal fat accumulation in diabetic women. Blood glucose concentration is independently effected by exercise, and exercise does not affect the WHR. Therefore, control of caloric intake and development of specific exercises to change the WHR seems important for controling diabetes in female subjects.

Purpose: The aim of this study was to apply suboccipital muscle inhibition combined with neck muscle stabilization exercise to 20~30s IT industry employees who suffer from chronic non-specific neck pain. Methods: This study was designed as single-blind and randomized controlled trial. The study participants were 20~30s IT industry employees with chonic non-specific neck pain (VAS 3/10) who were divided into an experimental group (n= 20) subjected to suboccipital muscle inhibition with neck muscle stabilization exercise, and control group (n= 20); suboccipital muscle inhibition only. The intervention was applied three times per week for eight weeks. The neck pain·pressure pain threshold·range of motion, and disability index were measured at the 1st, 8th, and 10th week at follow up, then analyzed with an analysis of variance(ANOVA) using the SPSS program. Results: The total number of study participants was 37 (experimental group 19, mean age 34.6±5.3, control group 18, mean age 35.7±4.9). The comparison and analysis of change in VAS, the pressure pain threshold, and the range of motion except the extension (p>.05) revealed a statistically significant decrease between groups over eight weeks and follow up measurement (p<.01). Regarding the within the group differences, the right side of the neck pressure pain threshold showed a statistically significant decrease over eight weeks in the control group (p<.01). The right and left lateral flexion, and the right and left rotation were statistically significant for the experimental group over eight weeks and follow up measurement, but only the left lateral flexion (p<.05) for the control group over eight weeks. The neck disability index showed a slight decrease but this was not satistically significant for the between-grop or the within-group differences (p>.05). Conclusion: The intervention of suboccipital muscle inhibition and a neck muscle stabilization exercise are more beneficial for neck pain and the range of motion than the application of suboccipital muscle inhibition alone.

Purpose: This study aimed to prove the effect of exercise therapy on discomfort and low back pain after cerebral endovascular surgery through femoral artery. Methods: The study employed a non-equivalent control group pretest-posttest design. Data were collected from 74 participants and were divided equally into two groups as experimental and control groups. In the experimental group, exercise therapy was applied in 2 hours, 4 hours, and 6 hours after cerebroendovascular surgery. The level of discomfort, back pain, hemorrhage, and hematoma was observed and recorded as a pretest. In the posttest, low back pain, hemorrhage, and hematoma were measured in 2.5 hours, 4.5 hours, and 6.5 hours, and discomfort was measured in 6.5 hours. The study was conducted from April to September, 2012. Data were analyzed with descriptive study, Chi-square test, t-test, repeated measure ANOVA and Bonferroni using SPSS/WIN 18.0 version. Results: The exercise therapy after cerebral endovascular surgery helps in reducing the level of discomfort (t=-2.37, p=.020) and low back pain (F=5.15, p=.005) without the side effects of hemorrhage or hematoma. Conclusion: Therefore, the exercise therapy was an efficient intervention for patients after cerebral endovascular surgery with discomfort and low back pain. Nurses could apply non-pharmacological interventions such as exercise therapy to avoid pharmacological side-effects.

Background: This study compared the effects of trunk stabilization exercise and hip joint exercises on the range of motion of the lumbar spine, pain severity, and severity of disability in patients with chronic lower back pain. Methods: A total of 30 participants were enrolled and divided into group 1 (n=10), group 2 (n=10), and group 3 (n=10) were performed by each group thrice a week for a total of 8 weeks. Group 1 performed warm-up exercise (15 min), trunk stabilization exercise (25 min), finish-up exercise (15mins). Group 2 performed warm-up exercise (15 min), hip exercise (25 mins, finish-up exercise (15mins). Group 3 warm-up exercise (15 min), trunk stabilization and hip exercise (25 min), Finish-up exercise (15 min). Participants were assessed for the range of motion of the lumbar spine, pain severity (visual analog scale score; VAS), and severity of disability (Oswestry disability index score; ODI) before and after the interventions. Results: All three groups showed a significant increase in the range of motion of the lumbar spine, but there was no significant difference among the groups. Moreover, the severity of pain and ODI were significantly decreased in all groups; however, the intergroup differences were non-significant. Conclusion: The results from this study confirmed the effectiveness of trunk stabilization and hip joint exercise in improving the lumbar range of motion, pain severity, and chronic lower back pain in patients. Thus, trunk and pelvic stabilization exercises and hip joint exercise can be used as clinical practices to treat and prevent chronic lower back pain.

Purpose: The purpose of this study was to confirm the effects of a moderate and fast walking exercise program on middle-aged women's fatigue, serum lipids and immunoglobulins. Method: A non-equivalent control group pretest-posttest design was used for this study. The experiment was conducted for 10 weeks from May 17th to July 25th, 2004 with 44 middle-aged women, consisting of 16 for the moderate walking group, 15 for the fast walking group and 13 for the control group. Result: Walking exercise at both a moderate and fast speed was effective in middle-aged women in reducing fatigue and serum lipids. It was also revealed that extended periods of exercise was more effective in decreasing fatigue while for reducing serum lipid, high intensity exercise was more effective. In this study, serum immunoglobulins were reduced after moderate and fast walking exercise but its cause was not fully understood so further research is needed. Conclusion: This study helps us recognize the importance of regular exercise and promotes motivation to exercise for a healthy life among middle-aged women.
