The decrease of muscle power and muscle size between twenties and seventies was about 30% and 40% respectively. The loss of muscle mass by aging resulted in the decrease of muscle power. The loss of muscle mass was due to the decrease of number of Type I fiber and Type II fiber and size of each muscle fiber. The aging skeletal muscle didn't show the loss of glycolysis capacity but showed 20% decrease of the oxidative enzymes and muscle vascularization. The vigorous endurance exercise training with graded intensity played a role in the vascular proliferation, increase of activity of oxidative enzymes and improvement of $VO_2$ max. The graded resistance exercise also played a role in the muscle hypertrophy and increase of muscle power, if it performed with adequate intensity and period. The exercise adaptation of aging skeletal muscle prevented it from sarcopenia, provided the activity of daily living with great effect and provided the aging related disease, that is Type II diabetes mellitus, arteriosclerosis, hypertension, osteoporosis and obesity, with great effect.

Purpose: This study aimed to describe the current level of physical activity (PA) and to explore the relationships between self-efficacy for PA, perceived health status (PHS), attitudes toward aging, ego-integrity and PA in community-dwelling older Koreans. Methods: A total of 164 participants were recruited from community centers, churches, and senior welfare centers in Korea. With questionnaires, a survey was conducted from June 3rd to 22th, 2016. Data were analyzed with descriptive statistics, independent t-test, one-way ANOVA and Pearson's correlation coefficient using SPSS/WIN 22.0 program. Results: The mean amount of total PA was 5,295.33±6,272.38 MET/min/week. The number of subjects engaged in vigorous, moderate, and low-intensity activities were 87 (53.0%), 45 (27.4%), and 32 (19.5%), respectively. Overall, physical activities were different according to the presence of spouse (t=-2.79, p=.006) and the presence of housemate (t=2.03, p=.044). The mean scores of self-efficacy for PA, PHS, attitudes towards aging, and ego-integrity were 17.16±4.45, 9.00±2.41, 68.12±9.28 and 51.62±7.59, respectively. There were significant positive correlations between overall PA and self-efficacy for PA (r=.34, p<.001), PHS (r=.23, p=.003), attitudes towards aging (r=.26, p=.001). Conclusion: Specific programs to promote physical activities in addition to continuous education for improving self-efficacy for PA, PHS, and attitudes towards aging in community-dwelling older adults are needed.

According to the National Health Insurance Corporation in 2008, there were 17,764,428 physical therapy patients, exceeding 31 percent for the population covered by health insurance. This means that three out of 10 Koreans received physical therapy. And now, 10 years later, due to the aging population and the increase in the sports population, the number of patients with physical therapy is expected to be much more than a decade ago. Among them, many physical therapy patients were orthopedic and neurologic disorder. However, in the medical field applied to physical therapy, it is widely applied across all medical fields, including orthopedics, neurosurgery, pediatrics, gynecology, thoracic surgery and dentistry. It is believed that various cases of patients receiving physical therapy will be secured. as mentioned earlier, there will be a large number of patients with physical therapy treatments, making big data analytics easier. based on this, physical therapy applications are thought to be helpful in the analogy of disease and the development of effective physical therapy and will ultimately promote the development of physical therapy.

Purpose : An aging phenomenon was recognized as only negative aspect, which impediment a development with the decrease of a developing population and increase of social burden. Nevertheless, the problem of aging cannot be treated as a problem of individuals or social burden. Because Every mankind sometime will be the person directly involved the aging. Methods : Korea, predict to reach the aging society with over 20 percent of elderly in the whole population in 2020, should find an active political plan for responding. Because a previous discussion about the aging phenomenon focused on social welfare, the housing plan for the elderly with a consideration of the physical environment for sustaining elderly's life with happiness will be primary task. Results : This research considers housing policy, focusing on the medical service. It is because statistics, which 85 percent of elderly people suffer from chronic diseases because of physical aging signify the importance of medical service to the elderly in every-day-life. Implications : We prescribe the elderly as a population over 65. In this duration, the elderly retirees from the workplace e and spend the majority of time in their home. Thus, for the elderly, the residential space is a field of action and passageway connecting with the surroundings For the solution of physical space preparing the aging phenomenon, the combination of residential and medical function creates a new type of a lifestyle.

Purpose: The purpose of this study was to measure the level of expectations regarding aging (ERA) and identify relationship between ERA and physical activity of middle aged adults. Methods: Participants were middle aged adults who resided in the community in three cities in Korea. Data were collected using questionnaires that contained items on individual characteristic, International Physical Activity Questionnaires (IPAQ), and behavior-specific cognitive factors including ERA-12. Hierarchical multiple regression was conducted to examine whether ERA would predict physical activity by controlling other factors. Results: The mean age of the participants was $51.1{\pm}6.9$ years. The mean score for ERA (possible range=0 to 100) was $40.04{\pm}14.31$. More than half of the participants (62.6%) were not engaged in health promoting physical activity. Gender, employment status and exercise confidence were associated with level of physical activity (F=7.14, p<.001, $R^2=.36$). After controlling for individual factors and behavior-specific cognitive factors, ERA was independently related to physical activity (F=7.19, p<.001, $R^2=.38$). Conclusion: The results demonstrate that individuals' belief about aging has effects on physical activity in Korean middle aged adults. Thus, nursing interventions which focused on ERA could help enhance physical activity in middle aged adults.

Purpose: The purpose of this study was to investigate the aging anxiety, factors of successful aging, and preparation for aging in early and late middle-aged people. Methods: The study subjects were 140 middle-aged people aged from 40 to 59. Data were collected using a self-administered questionnaire from August 16 to September 30, 2013. The collected data were analyzed with descriptive statistics, t-test, ${\chi}^2$-test and Pearson correlation coefficient using IBM SPSS 21.0 program. Results: Between early and late middle age, there were statistically significant differences in the subcategories of aging anxiety: fear of loss (t=2.93, p=.004), fear of old people (t=-2.33, p=.021), physical appearance (t=2.32, p=.022), and psychological concerns (t=2.04, p=.043). A statistically significant difference was found between two groups in one subscale of preparation for aging: physical preparation (t=-2.02, p=.045). In early midlife, significant associations were observed between preparation for aging and both aging anxiety (r=.56, p<.001) and factors of successful aging (r=.54, p<.001). In late midlife, preparation for aging and factors of successful aging showed positive correlation (r=.50, p<.001) Conclusion: Results of this study indicate that programs for successful transition to old age in middle-aged people should consider their aging anxiety level and preparation for aging at their stage of life.

Background: Muscle undergoes change continuously with aging. Sarcopenia, in which muscle mass decrease with aging, is associated with various diseases, the risk of falling, and the deterioration of quality of life. Obesity and sarcopenia also have a synergy effect on the disease of the older adults. Objects: This study examined the risk factors for sarcopenia, sarcopenic obesity, and sarcopenia without obesity and developed prediction models. Methods: This machine-learning study used the 2008-2011 Korea National Health and Nutrition Examination Surveys in the analysis. After data curation, 5,563 older participants were selected, of whom 1,169 had sarcopenia, 538 had sarcopenic obesity, and 631 had sarcopenia without obesity; the remaining 4,394 were normal. Decision tree and random forest models were used to identify risk factors. Results: The risk factors for sarcopenia chosen by both methods were body mass index (BMI) and duration of moderate physical activity; those for sarcopenic obesity were sex, BMI, and duration of moderate physical activity; and those for sarcopenia without obesity were BMI and sex. The areas under the receiver operating characteristic curves of all prediction models exceeded 0.75. BMI could predict sarcopenia-related disease. Conclusion: Risk factors for sarcopenia-related diseases should be identified and programs for sarcopenia-related disease prevention should be developed. Data-mining research using population data should be conducted to enhance the effectiveness of early treatment for people with sarcopenia-related diseases through predictive models.
