Purpose: The purposes of this study were to examine the effects of home visit healthcare using a complex program on community-dwelling frail elders' physical strength, frailty, and depression and to compare the effects among three regions. Methods: This study was conducted as a quasi-experimental study using one-group pretest-posttest design. A total of 86 subjects were sampled from three regions (metropolis, small city, and rural area). The program was applied for 14 weeks. This program consisted of disease management by a visiting nurse, exercise with a visiting nurse, self exercise, telephone monitoring, health education, counseling, providing handbook, and incentive. Physical strength was measured by balance, upper-limb, and lower-limb muscle strength. Frailty was measured by the Korean Frail Scale and depression was measured by the Geriatric Depression Scale. Paired t-test and ANCOVA were used to analyze the effects. Results: Physical strength, frailty, and depression were significantly improved after applying the complex program. There were not differences among the regions. Conclusion: Home visit healthcare using a complex program was effective in improving frail elders' physical strength, frailty, and depression. There were not differences among the regions. Therefore, home visit healthcare using a complex program needs to be expanded to other regions.

Nowadays, interest in health care is increasing due to Coronavirus (COVID-19), and a lot of people are doing home training as there are more difficulties in using fitness centers and public facilities that are used together. In this paper, we propose a personalized exercise recommendation algorithm using personalized propensity information to provide more accurate and meaningful exercise recommendation to home training users. Thus, we classify the data according to the criteria for obesity with a k-nearest neighbor algorithm using personal information that can represent individuals, such as eating habits information and physical conditions. Furthermore, we differentiate the exercise dataset by the level of exercise activities. Based on the neighborhood information of each dataset, we provide personalized exercise recommendations to users through a dimensionality reduction algorithm (SVD) among model-based collaborative filtering methods. Therefore, we can solve the problem of data sparsity and scalability of memory-based collaborative filtering recommendation techniques and we verify the accuracy and performance of the proposed algorithms.

As the effects of COVID-19, many changes are occurring in the daily life. Breaking away from the temporal and spatial restrictions, the exercise method utilizing converged device in non-contact fashion is emerging. In the present study, home training with utilization of the converged device for fall prevention and improvement of daily life in behalf of the frail elderly has been composed, and execution process designed. Converged device-based exercise program extracted through Delphi analysis is composed of essential 8 types of motion reflecting the performance capability of the frail elderly as the subject, though easy, have been selected. Converged device-based exercise program configured the system in a structure of subject, interface, and administrator for the purpose of utilizing this exercise program. Overall execution process is composed 3 stages, and implemented with the elderly and the trainer being converged via medium. For the overall implementation, the elderly performs the exercise program under leading of the trainer as the administrator. Depending on the condition of the elderly as the subject, the trainer selects the difficulty of exercise, which the elderly performs and implements the exercise program while communicating with the trainer. The converged device-based exercise program that is applicable to the elderly as a digitally vulnerable class is expected to bring about not only fall prevention and increased physical activities but also subsidiary effects of producing digital device-friendly environments for the elderly as a digitally vulnerable class.

Recently, with the development of AR, VR, and smart device technologies, the demand for services based on non-face-to-face environments is also increasing in the fitness industry. The non-face-to-face online home training service has the advantage of not being limited by time and place compared to the existing offline service. However, there are disadvantages including the absence of exercise equipment, difficulty in measuring the amount of exercise and chekcing whether the user maintains an accurate exercise posture or not. In this study, we develop a standard exercise program that can compensate for these shortcomings and propose a new non-face-to-face home training application by using a deep learning-based body posture estimation image processing algorithm. This application allows the user to directly watch and follow the trainer of the standard exercise program video, correct the user's own posture, and perform an accurate exercise. Furthermore, if the results of this study are customized according to their purpose, it will be possible to apply them to performances, films, club activities, and conferences

PURPOSE: This study examined the effects of posture improvement exercise using virtual reality programs on the posture and balance of patients with forward head postures. METHODS: Thirty men and women in their 20 s, who had a forward head posture, were divided randomly into a group with posture correction exercise and a group with posture correction exercise combined with virtual reality programs. The posture correction exercise was composed of squats, XCO training, and chin-tuck exercise. In contrast, exercise with virtual reality games involved the Hot Squat, Climbey, and Baskhead programs while wearing a headset. Both groups performed the exercises 15 min a day, three times per week, for four weeks. The balance ability, distance between the acromion and earlobe, and neck joint range of motion were assessed before and after the exercises. RESULTS: Both groups showed significant reductions in the distance between the acromion and the earlobe, along with significant improvements in the range of joint motion. The group that performed the virtual reality exercises showed a significant increase in the limit of stability. Both groups showed a significant decrease in the sway length. In contrast, the group given the virtual reality exercises showed a significant reduction in the sway speed while standing with their eyes closed. CONCLUSION: Exercise applying virtual reality programs can be used in clinical and home programs to correct the postures of individuals with a forward head posture because they can trigger interest in inducing active participation.

The purpose of this study was try to check the change of a subjective evaluation about the life function fitness and health-related quality of life by executing the home support exercise program three times a week for total 16 weeks with elderly women that are order than 70 years old. The experiment group(total : 17 people, mean age : 79.4) and the control group(total : 17 people, mean age : 80.7) live Yeonje-gu in Busan city, and they don't have any physical injury and any inconvenience to move. and they are all composed of elderly women who agree to participate in this study. We carried out an analysis of covariance with SAS 9.2 statistics package. These are the results from it. First, the experiment group showed statistically significant increase(p<.001) in lifting dumbbells, repeatedly standing up and sitting down, 2.24m shuttle running, walking at the same place for 2 minutes. Second, there was no particular effect with the experiment group in flexibility(catching hands with their backs leaned against each other). This result point out that there is a need of supplementation like adding exercise item which can improve flexibility to home support exercise program. Third, there was no particular difference between the experiment group and the control group in 8 sub-factors with the subjective evaluation about health-related quality of life through SF-36. However, there the bodily pain and vitality sub-factors of experiment group was better than that of the control group with p<.10 level, so we considered this result showed us the positive effect slightly.

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.

PURPOSE: The purpose of this study is to find out the thickness variation of the superficial and deep abdominal muscles by measuring the thickness of the abdominal muscles. METHODS: 35 young, healthy adults(24 mens and 11 womens) participated in this study. The first, when only bridge exercise we had measured the thickness of their abdominal muscles by the ultrasound. The second, when the abdominal drawing-in during maintaining the bridge exercise we had measured the thickness of their abdominal muscles by the ultrasound. A pared t-test was used to determine a statistical significance for the thickness variation of the superficial and deep abdominal muscles. RESULTS: Results of before and after comparative analysis. The surperficial muscles(rectus abdominis, external obilique) statistically significantly reduced in the thickness and the deep muscle(transeverse abdominis) statistically significantly increased in the thickness. CONCLUSION: We have shown that the abdominal drawing-in exercise during maintaining the bridge exercise was effective to increase in strengthening abdominal deep muscle selectively.
