Blood flow restriction(BFR) exercise is defined as low intensity and short term exercise using pneumatic pressure belts at the top of limbs, which affects the physiological functions of the body. The purpose of this study was to investigate the effects of walking exercise with BFR on inflammatory index, isokinetic muscle function, and thigh circumference in obese women. Eleven obese women(> BMI $25kg/m^2$ & > body fat 30%) wore pneumatic pressure belts on both femurs and performed walking exercise twice per day, 3 days/wk for 4 weeks (walking 2 min; resting 1 min). Data analysis was carried out using paired t-test. Body weight, BMI, and body fat significantly decreased after exercise(p<.05), and right thigh circumference significantly decreased(p<.05). The concentration of plasma IL-6 significantly increased(p<.05) after exercise. TNF-${\alpha}$ level was not statistically different but tended to slightly increase. CRP slightly decreased, although it did not reach statistical significance after exercise. Muscle strength significantly increased in the $60^{\circ}/sec$ of right/left side extension, left side flexion, and $180^{\circ}/sec$ of left side extension after training(p<.05). These results suggest that 4 weeks of blood flow restriction walking exercise has positive effects on inflammatory index and isokinetic muscle function. Therefore, we consider that blood flow restriction exercise can be used for treatment of obesity, related chronic diseases, and metabolic syndrome. Further, blood flow restriction exercise for a short time has similar effects as a high intensity resistance program.

건강에 대한 관심이 높아지면서 동시에 이에 대한 대안으로 운동에 대한 관심 또한 높아지고 있다. 걷기는 기구나 다른 사람 도움 없이 쉽게 할 수 있어서 많은 운동 중에서 선호도가 높으며, 이에 따라 많은 지자체에서는 걷기 운동 활성화를 위해 코스를 만들고 있다. 하지만 기존에 개발되어 사용되는 어플리케이션은 코스에 대한 일반적인 정보들만을 보여주고 있어서 여러 한계점을 가진다. 본 논문에서는 특정지역의 걷기 코스 정보들을 반영한 위치 기반 어플리케이션 구조를 제안하고 개발 사례를 통해 타당성과 효과성을 검증한다. 본 구조에서는 특정 걷기 코스에 대해 정보가 제공되어 사용자 입장에서는 코스에 대한 자세한 정보를 통해 운동효과를 높이며, 코스 관리자에게는 사용자 피드백과 운동 데이터를 통해 코스의 유지, 관리, 개선에 도움을 받으며, 마지막으로 운동 데이터를 필요로 하는 분석자들에게는 실제 데이터를 제공할 수 있어 관련 연구에 도움을 줄 수 있는 장점을 가진다.

The aim of this study was to examine the effect of a brisk walking intervention for 8weeks on isokinetic muscular function factor(strength, power, endurance). The following results were found from the current study: First, Isokinetic muscle function(strength, power, endurance) on $60^{\circ}/sec$ in extension and flexion was significant exercise group and interaction in left knee flexion and right knee extension(P<.00l). Secondly, Isokinetic muscle function(strength, power, endurance) on $120^{\circ}/sec$ in extension and flexion was significant exercise group and interaction in left knee flexion and right knee extension(P<.001). Thirdly, Isokinetic muscle function(strength, power, endurance) on $180^{\circ}/sec$ in extension and flexion was significant exercise group and interaction in left knee flexion and right knee extension(P<.001). Considering the above result of the study the brisk walking had more improvement knee flexor and extensor muscular power. Therefore the brisk walking in the study can be proposed as effective plan to prevention hurt from a sarcopenia and to raise quality in life.

Metabolic syndrome and allergic rhinitis are two important chronic diseases that affect people all over the world. Metabolic syndrome very often induces other diseases and the prevalence of allergic rhinitis is currently increasing. Aging is known to affect the pathogenesis of various diseases such as metabolic syndrome and allergy. This study examined the effects of metabolic syndrome and the prevalence of allergic rhinitis depending on different age groups and several general characteristics. This study was conducted by using the data from the Korea National Health and Nutrition Examination Survey from the 4th, 5th, 6th, and 7th-1 (2007~2016). The data used for this study was obtained from 51,854 people. In all age groups, our studies have shown that people without metabolic syndrome have a higher prevalence of allergic rhinitis than those people with metabolic syndrome, and the younger age group had the higher prevalence of allergic rhinitis (P<0.05). Overall, the results of this study found a significant effect on the prevalence of allergic rhinitis in each category of age, general characteristics (physical activity, smoking and drinking) and the presence or absence of metabolic syndrome (P<0.05). The evidence found in this study will help to understand the correlation between metabolic syndrome and allergy, and specifically allergic rhinitis.

The purpose of this study is to identify walking time, self-efficacy for exercise, sleep quality and depression in order to confirm the relationship between college students' activity level and psychological index. The research method is a cross-sectional descriptive survey of college students. The subjects of this study were 135 students enrolled in colleges in Gyeongbuk. Self-efficacy for exercise was higher than the average, and walking time was about 1.7 hours per day on average, walking less than 2 hours. Sleep quality was most of them had problems with their sleep quality (71.9%). Depression was about half of the students showed a tendency to be depressed (49.6%). It was found that there was a correlation between self-efficacy and depression for exercise (p=.012). This study can be used as basic data for the development of programs to increase physical activity and improve psychological index of college students in the future.

The purpose of this study was to investigate the effects of aquatic walking exercise on body composition, hs-CRP, HOMA-IR, and blood pressure in obese elderly women. Twenty, obese elderly women[percent body fat(%BF) < 30%] composed of aquatic walking exercise group(EX, n=10), the control group(CON, n=10). The variables of body composition, hs-CRP, HOMA-IR, and blood pressure were measured in all the subjects pre and post of 12 weeks aquatic walking exercise(RPE 11-14, 3 times per week, 50 mins). The test data were analyzed by paired t-test and repeated ANOVA, and the alpha level of p<.05 was set for all tests of significance. %BF (p<.05), insulin (p<.01), HOMA-IR (p<.01) and SBP (p<.05) were significantly decreased in EX group compared to CON group. These results suggest that 12 weeks of aquatic walking exercise improves %BF, HOMA-IR, and blood pressure. Thus, this proposed aquatic walking exercise modality can be a useful therapy to improve both obese and cardiovascular disease in obese elderly women.

노년에게는 근력운동이 아닌 걷기, 달리기, 수영 등 유산소운동이 적합한 운동으로 알고 있다. 근력운동을 하다가 자칫 잘못하면 더 큰 부상을 당할 수 있고, 운동 효율이 낮기 때문이다. 하지만 최근에는 근력운동이 노년에게도 필요하다는 주장이 점차 힘을 얻고 있는 추세이다. 구릿빛 피부에 울퉁불퉁한 식스팩까지는 아니지만 분명 노년을 건강하게 보내기 위해서는 근육이 필요하다.

Objectives: This study was performed to find the differences in physical activity according to general characteristics and factors related to physical activity between the elderly over 65 with hypertension living rural and urban areas. Methods: This study included 681 participants (221 rural, 460 urban) with hypertension from The Fifth Korea National Health and Nutrition Examination Survey (KNHANES V). The collected data were analyzed through an $x^2$-test to examine the differences in physical activity and multiple logistic regression to assess factors related to physical activity between the elderly over 65 with hypertension living rural and urban areas. Results: The significant statistical factors related with physical activities for the urban hypertension group were education level, activities of daily living, and quality of life. However, the related factors for rural residents were activities of daily living and limitation of activity. Conclusions: The study results indicated that the factors that affected the level of physical activity revealed difference in case hypertension between the urban and rural groups. An awareness of the importance of physical activity will have a positive influence on improving the physical function and quality of life for elderly people with hypertension.

We have developed a serious game for the elderly named 'Paldokangsan 2' in 2012 as a next version of 'Paldokangsan 1'. 'Paldokangsan 1' was a walking game for two people using controllers of armrests and footboards with PC. 'Paldokangsan 2' had additional purpose to assist cognitive, physical, and psychological functions of the elderly. Especially, walking activity was implemented in a way that a player walks around the old traditional market place in 1970's while remembering and choosing healthy food to buy. We also developed two mini games for the elderly and people with functional disability with the similar purpose as 'Paldokangsan2'. 219 older adults (age$$\geq_-$$ 65) recruited from Asan city community center participated in the study. The result showed that the game play exerted positive effects on memory, concentration and vitality of the elderly.
