We have developed a serious game for the game-aided human life and entertainment for the elders with the concept of enjoying scenic beauties in Korea walking in the room using controllers of armrests and footboards with PC. The expected effects of the game are the satisfaction of bodily sensation with cooperation and competition, and also remedy by entertainment such as vital power, maintaining mental functions with the game playing. We have tested 309 elders who were more than 65 years old in Cheonan city community center for the elderly. 76.1% of them answered they were satisfied totally for the game play, average grade for the interest/fun of the game was 4.13 points with full 5 points. 89.4% of them replied they would like to play the game again. We found the intended permissiveness and coenesthesia of the game was appealing to elders.

Purpose: The purpose of the study was to identify the effects of problem solving nursing counseling and intensified walking exercise on diabetic self-care, coping strategies, and glycemic control among older adults with DM type II. Method: Ninety nine DM patients who were older than 50 were recruited from DM clinics or public health centers and conveniently assigned into three groups: the Polar(n=41), counseling(n=30) and control groups (n=28). Participants in both Polar and counseling groups attended weekly problem solving nursing counseling for 12 weeks. Polar heart rate monitors were used in the Polar group to intensify walking exercise. Data was collected from November 2003 to August 2004 and analyzed by ANOVA or ANCOVA using the SPSS WIN program. Result: After a 12 week intervention, participants in both the Polar and counseling groups reported increased diabetic self care behaviors and decreased blood glucose levels, which is significantly different from those in the control group. There were no distinctively different program effects between the Polar and counseling groups. Conclusion: Based on the findings, we concluded that problem solving counseling alone could have positive effects on diabetic self care and glycemic controls for older adults with DM. Future research is needed to identify long-term effects of the program.

This study was a quasi-experimental study of nonequivalent control group pretest- posttest design to investigate the effect of aerobic walking exercise program on the physical & psychological functions of home stayed stroke patients. The data were collected during the period of May 20th to August 15th, 2001. The subjects for this study were 40 hemiplegic stroke patients with the experimental group consisting of 19 patients and the control group being composed of 21 patients. The patients selected for this study were: (a)living in J city who had been diagnosed with stroke and at home after being discharged from the hospital, (b)suffering from stroke for 6 months to 5 years, (c)without recognition disorder with the MMSE-K score above 25, (d)below 2 on the modified Ashworth scale, (e)free from heart and pulmonary disease (f)able to walk beyond 15 minutes for themselves. The aerobic walking exercise program for the experimental group was aerobic exercise and education and supportive care. The aerobic exercise was 8 weeks' period, three times a week, 35 to 50 minutes a day. And the education and supportive care was consisted of one home visiting and 2 times telephoning a week. The data were analysed by $X^2$-test, paired t-test and unpaired t-test and ANCOVA through SAS/PC program. The results of the study were as follows: 1. There was insignificant difference in the gait length experimental and control group. There was significant difference in the gait speed between the two groups. 2. There was significant difference in the dynamic valance between the two groups. 3. There was significant difference in ADL score between the two groups. 4. There was no significant difference in the depression between the two groups. As shown above, the results of 8 weeks' the aerobic walking exercise program for home stayed stroke patients produced positive effects on gait speed, dynamic valance, ADL score. And this program was expected that it was more effective in different intervention period, verified program. Also it was needed follow study.

The purpose of this study was to investigate possibility of a forward gait with backward mechanism(dance gait) as rehabilitation and/or walking exercise by means of biomechanical variables. Thirteen professional women dancers(age, $21.1{\pm}1.3yrs$; height, $159.3{\pm}7.2cm$; body mass, $45.1{\pm}8.4kg$)participated in this study. We found that speed, stride length and double limb support time of a dance gait were more greater than backward gait, but stride width of dance gait less than a backward gait. Maximum RoMs, moments and powers of the lower limb joints on a dance gait were more frequent than a backward dance. These results were judged to be sufficient by the possibility of dance gait as rehabilitation and walking exercise.

Previous epidemiological studies reported that significant muscle loss is observed with advancing aging, called sarcopenia. This study is to investigate the effects of treatment dumbbell exercise on prevention of sarcopenia. The subjects were elderly between 60~70 years old who participated in J-Welfare senior center exercise program at J-gu in S-city and divided into control group(N=19) and exercise group(N=8). Treatment dumbbell exercise was performed 2 times per week for 12 weeks and body composition, fitness, and blood lipid profiles were measured before and after this program. There was no significance in body fat before and after 12 weeks of treatment dumbbell exercise, but there was significance in weight(F=4.312, p=0.048), BMI(F=4.532, p=0.043), and FFM(F=4.743, p=0.039). There was no significance in fitness such as arm curl(F=1.103, p=0.304), and back scratch(F=0.214, p=0.648), but there was significance in 2-minute step(F=33.638, p<0.001), chair stand(F=14.575, p=0.001), chair sit and reach(F=7.198, p=0.013), and 8-ft up and go(F=14.890, p=0.001). The variables of blood lipid profiles such as TC(F=0.030, p=0.864), TG(F=0.142, p=0.710), HDL(F=2.066, p=0.163), glucose (F=0.125, p=0.727), and HbA1c(F=0.945, p=0.340) has no significance. It was found that treatment dumbbell exercise has positive effects on body composition and fitness but has no positive effects on blood lipid profiles of the elderly.

The life expectancy of people has been steadily extended due to the improvement of living standards and the development of medical technology. Besides, the low birth rate and long life expectancy decrease the youth population while the elderly population is steadily increasing. Many elderly people have enough time and financial allowance, and the interest in health care is increased all over society. There are also increasing numbers of elderly people who exercise lightly in the playgrounds and parks such as running and walking. Outdoor fitness equipment that can be easily seen in neighbourhood parks, public spaces, etc. can be good health promotion tools that can be easily accessed in the daily life of the elderly. Outdoor fitness equipment Description Signs require a design that takes into account the declining vision of older users. Proper design is also important for the prevention of safety accidents in use. The purpose of this study is to find out the perception of the elderly about outdoor fitness exercise equipment sign system and to find the problem of recognition. To do this, we conduct user observation and interview surveys for the elderly. As a result, the emphasis of the caveat or problems with the size of the writing were pointed out, and it was necessary to explain the picture rather than the text. Also, there was a high demand for refraining from using foreign words, using universal words and including motor effects in signs. Based on the results of the user observation and interviews, we propose guidelines for the use of outdoor exercise equipment.

One year has passed since the pandemic of COVID-19, which occurred in Wuhan, China, in November 2019 began. Worldwide, as of January 2021, more than 95 million people have been infected, and the death toll is higher than 2 million. In Korea, there are 74,262 infected and 1,328 dead, and government policies such as social distancing to prevent infection are being implemented. Accordingly, many inconveniences occurred in the physical activity environment, such as the closure of various sports facilities. It was necessary to consider physical activities to maintain healthy life while cooperating with the national policy while preventing infection. This study investigated the benefits of physical activity to reduce the risk of trichomoniasis and diabetes, improve bone mineral density, prolong healthy lifespan, maintain activity performance with aging, and improve psychological anxiety and depression. In addition, the physiological changes that may occur in the situation of stopping exercise due to social distancing to prevent COVID-19 infection were reviewed. In addition, moderate-intensity exercise that helps strengthen immune function by activating natural killer cells, neutrophils, and antibody responses was investigated. In addition, it reduces the level and function of blood B-cells, T-cells, and natural killer cells for several hours, decreases phagocytosis of neutrophils in the nasal cavity, increases inflammatory cytokines, decreases immune function, and increases infection. High-intensity exercise was considered. Therefore, in the age of COVID-19, long-term high-intensity exercise such as marathon, which causes impaired immune function, should be refrained from. And you should do moderate-intensity regular aerobic exercise such as fast walking to help prevent infection. It is also recommended to participate in resistance exercises to prevent loss of muscle mass.

Objective: The purpose of this study is to analyze the effects of aquatic walking exercise on gait and balance parameters of elderly women. Method: 15 elderly people were recruited for this study (age: 73.20±5.19 yrs, height: 153.87±3.36 cm, mass: 60.33±5.73 kg). All variables were measured using Gaitview AFA-50. The variables were the heel contact time ratio, gait angle, and M/P change ratio for gait patterns and ENV, REC, RMS, Total Length, TLC, Sway velocity, and Length/ENV for balance abilities. A paired t-test and the Wilcoxon signed-rank test were carried out to verify the differences in the test scores after participating in the water walking program. The significance level for all statistical analyses was set to α=.05. Results: As for the changes in their walking function after the exercise, heel contact time ratio (p<.01) showed a statistical significance, while gait angle and M/P change ratio did not reveal statistically significant differences. In the test of balance ability on both feet and with eyes opened, statistical significance was found in ENV, REC, RMS, TLC (p<.01), and sway velocity (p<.05), while the test with eyes closed showed statistical significance in length/ENV as well as ENV, REC, RMS, sway velocity (p<.01) TLC, and total length (p<.05). As for the single-leg stance balance ability, ENV and REC revealed statistically significant differences. Conclusion: These results show that water walking is effective for improving the function of the ankle flexor muscles, providing stability to the ankle joint during walking and helping efficient walk. In addition, it is also expected to help prevent falls due to loss of balance by improving the stability of lower extremity muscles and trunk.
