This study was conducted to determine whether low intensity regular exercise following steroid treatment could attenuate steroid-induced muscle atrophy. Thirty-eight Sprague-Dawley rats weighing $165{\sim}175g$ were divided into six groups ; control group(C), dexamethasone administration group(D), sedentary normal saline administration group(C+Se), exercise after normal saline administration group(C+Ex), sedentary group after dexamethasone administration(D+Se), exercise group after dexamethasone administration(D+Ex). Either dexamethasone(5mg/kg) or normal saline was injected for 7days accordingly. Exercise was started at 10m/min on the $10^{\circ}$ grade treadmill and gradually increased up to 15m/min by the 7th day for 60minutes/day($20min{\times}3$). The data were analyzed by Kruskal-Wallis test and Mann-Whitney U test using the SPSS WIN 9.0 program. Body weight, muscle weight and myofibrillar protein content of both plantaris and gastrocnemius, Type I, II muscle fiber cross-sectional area of plantaris, and Type II muscle fiber cross-sectional area of gastrocnemius in D group were significantly lower than those of C group(p<0.05) respectively. Hindlimb muscle weight, myofibrillar protein content of both plantaris and gastrocnemius. Type I muscle fiber cross-sectional area of soleus and Type I, II muscle fiber cross-sectional area of plantaris in D+Ex group tended to increase compared to those of D+Se group. Myofibrillar protein content of both plantaris and gastrocnemius, Type I muscle fiber cross-sectional area of plantaris in D+Ex group tended to increase compared to those of C+Se group. Based on these results, it is suggested that regular low-intensity exercise during recovery period after steroid treatment might facilitate the recovery from steroid-induced muscle atrophy.

The purpose of this study was to investigate the needs for exercise of adult inpatients and ultimately to provide basic data for planning nursing intervention of patients who need exercise. The tool used for this study was a structured questionnaire which consisted of 42 items. The test items were classified into seven factors. The seven factors of the needs for exercise were need for achievement, need for activity, need for affiliation, need for autonomy, need for catharsis, need for homeostasis, and need for exhibition. Subjects of this study were 127 patients in two general hospitals in Seoul, and one general hospital in Chun Ann City. The needs of exercise were identified and the data were analyzed by gender, age, occupation, education level, monthly income, size of patient room, patient group who requires exercise and the other patient group who requires bed rest, using one-way ANOVA and Scheffe test as post-hoc. The findings of this study were as follows ; 1) Among the needs for exercise of adult patients, the highest level of the needs was the need for homeostasis. The next highest was the need for achievement, then need for activity, need for catharsis, need for autonomy, need for affiliation, and the lowest was the need for exhibition. 2) Maintaining physical fitness stood first in the need for homeostasis, relieving psychological and physical powerlessness in the need for activity, mood diversion in the need for catharsis, happiness of the family in the need for affiliation, maintaining the balanced body figure in the need for exhibition, practicing planned life in the need for achievement, and improving the ability to overcome the crisis in the need for autonomy. 3) Male patients exhibited the higher level of the needs than female patients in all factors except the need for exhibition and homeostasis. 4) There was no statistical difference in the needs between age, occupation, monthly income, and the size of patient room. 5) The need for achievement was high as the level of education goes higher. 6) The patients who performed regular exercise before admission had higher needs for activity, achievement, and autonomy, compared with the patients who did not perform the regular exercise before admission. 7) There was no statistical difference in the needs between patient group who requires exercise and the other patient group who requires bed rest. The need for homeostasis was the highest in both groups. The results from this study suggest that the need for exercise of adult inpatients should be assessed before planning exercise intervention.

Purpose: The present study analyzed the contents of exercise programs for the elderly in Korean and foreign articles. Method: This study analyzed 27 Korean and 20 foreign exercise-related articles selected from Web DBs using keywords 'exercise', 'exercise program' and 'exercise effect'. The collected data were analyzed using SPSS 11.5 through descriptive statistics, $x^2$ test and Fisher's exact test. Results: In the description of population, random sampling and informed consents, foreign articles were higher than Korean articles. In research design, foreign articles randomized controlled trials (RCTs) higher than Korean articles. The contents of exercise programs in the Korean and foreign articles were aerobic, walking and stretching. On the effects of exercise programs in the Korean articles, walking showed the highest frequency in the physical strength as well as muscle strength, balance and flexibility. In the foreign articles, walking and stretching showed high frequency in physical strength. Conclusion: Contents significant in exercise programs for the elderly were walking and stretching. In addition, regular exercise had a positive effect on muscle strength, flexibility and balance in the elderly.

Purpose: The purpose of our study was to evaluate the effects of an exercise program on activities of daily living (ADL), balance and cognition in elderly individuals with Alzheimer’s disease and vascular dementia. Methods: Thirty-two patients with mild to moderate cognitive impairment were assigned to one of two groups: an exercise group (n=16) and a control group (n=16). The exercise group carried on regular exercise for 60 minutes a day, 4-5 times per week for 8 weeks. The exercise group participated in an exercise program (treadmill training and physical training). ADL, balance and cognitive function were evaluated before and at the end of the program using the Korean modified Bathel Index (K-MBI), the Functional independence measure (FIM), the Berg balance scale (BBS), the Balance performance monitor (BPM), and the Mini mental state examination (MMSE) in both groups. Results: There were significant exercise-induced improvements in ADL and Balance from pre to post tests; but not in MMSE. Conclusion: Exercise programs can improve ADL and balance in elderly with Alzheimer’s disease and vascular dementia.

This study was conducted to develop wearable products with visual and auditory feedback aimed at promoting exercise interest in children. Here we determined the theoretical characteristics of cognitive and motor function development during childhood, empirical characteristics of children's motor functions, and factors that encourage exercise using natural observation and in-depth interview research methods. The questionnaire assessed children's motor ability, intensively trained body parts in sports programs, types of training or classes that improve the motor ability of each muscle group, significantly considered aspects of children's sports programs, and factors that promote children's interest in exercise. Our results suggest that the development of sport programs comprising varied exercise options that enhance body and limb movements are needed for balanced growth. Furthermore, it is very important to provide motivation for regular exercise and appropriate feedback, such as praise and encouragement, to maintain interest in exercise. This study identifies the standards for developing products that peak children's interest in exercise and the basis for a physically and mentally healthy society.

Stress at work as well as at home is one of the most important issues in the health sector. However, very little research has been to find the relationship between the levels of stress and exercise. In this study, we used a structured questionaires received from 15th June to 29th October 2002 in order to prove the relation between the degree of exercise and stress. A total number of 1,092( 569 male, 523 female) who have worked more than one year were investigated. The results of the study were as follows： (1) The mean levels of stress were lower in the regualr exercise group than in the non-exercise group； (2) The more time spent in exercise, the lower level of stress was shown； (3) It was shown that the association between the frequency of stress was inversely realted to the frequency of exercise in males whereas the levels of stress was lowest in those who exercised less than 2 times per week in females； (4) The levels of stress was lowest in those who exercised more than 1 hour at a time. In summarizing the result of this study, the degree of exercise is realted with stress regardless of gender. Consequently, it is expected that regular and consistent exercise would be an important tools in lowering and protecting the worker's stress.

This study investigates the exercise-physiological changes in stages through the movement of the automatic stepper and to analyze the usefulness of the automatic stepper. For 18 male university students, out of 10 levels, 5 level and 10 level of automatic stepper exercise were performed. At each 10, 20, 30 minutes during exercise, 5 and 10 minutes after exercise stop the subjects were examined to analyze the changes in energy consumption after minutes, respiratory exchange rate, heart rate, oxygen consumption per body weight, METs, cumulative energy consumption, and lactic acid to verify the usefulness of the automatic stepper. The mean and standard deviation were calculated using the SPSS, and one-way ANOVA with repeated measure was performed to verify the difference in the mean between time periods. The LSD method was used for the post-hoc test, and the significance level was set to α = .05. There were no significant changes in both 5 and 10 level, but the cumulative energy consumption over time increased significantly. In addition, as a low-intensity exercise intensity is shown, a low increase in lactic acid indicated a safe exercise level. In future studies, in-depth studies of various variables through regular exercise programs are needed for those who need safe exercise.

Cardiovascular disease (CVD) accounts for approximately 30% of all deaths worldwide and its prevalence is constantly increasing despite advancements in medical treatments. Cardiac remodeling and dysfunction are independent risk factors for CVD. Recent studies have demonstrated that cardiac structure and function are genetically influenced, suggesting that understanding the genetic basis for cardiac structure and function could provide new insights into developing novel therapeutic targets for CVD. Regular exercise has long been considered a robust nontherapeutic method of treating or preventing CVD. However, recent studies also indicate that there is inter-individual variation in response to exercise. Nevertheless, the genetic basis for cardiac structure and function as well as their responses to exercise training have yet to be fully elucidated. Therefore, this review summarizes accumulated evidence supporting the genetic contribution to these traits, including findings from population-based studies and unbiased large genomic-scale studies in humans.
