In this study, 80 elderly people aged 65 years or older living in Gyeongnam, South Korea were divided into a sarcopenia group (N=37) and a normal group (N=43) using an index determined by dividing the appendicular skeletal muscle mass (ASM), measured using dual-energy X-ray absorptiometry, by the square of height (ASM/Ht2). Obesity-related variables (waist and hip circumferences, body fat ratio, and blood pressure) and muscle reduction-related variables (ASM/Ht2, grip strength, static balance, and 6-minute walking speed) were measured and compared between the two groups. The conclusions are as follows: 1. The ASM, waist circumference, hip circumference, left and right grip strengths, and 6-minute walking speed were higher in the normal group than in the sarcopenia group, whereas the body fat ratio was higher in the sarcopenia group (p<.05). 2. The more obese people showed a smaller ASM, and the people with a larger ASM showed larger waist and hip circumferences and physical (e.g., muscle) strength (p<.05). 3. We found a difference in the presence or absence of circulatory system diseases according to the presence or absence of sarcopenia(p<.05). To summarize the results of this study, sarcopenia in the elderly is highly correlated with body fat and muscle reduction-related variables. Among the muscle reduction-related variables, grip strength, which corresponds to muscle strength, and 6-minute walking distance, which corresponds to endurance, were found to be highly correlated with sarcopenia. This highlights the importance of obesity and fitness management in sarcopenia.

본 연구에서는 수용전념치료(ACT)를 노인들의 만성통증에 적용하여 통증과 통증간섭, 삶의 만족도에 대한 치료효과를 검증하였다. 퇴행성 질환으로 만성통증을 호소하는 65세 이상의 노인들을 대상으로, 치료집단에는 ACT 집단 프로그램, 통제집단에는 건강교육을 총 8회기로 진행하였다. 결과분석에는 치료집단 25명과 통제집단 27명으로 총 52명의 자료를 사용하였다. 그 결과, 건강교육에 비해 ACT 프로그램은 통증과 통증간섭을 유의미하게 감소시켰으며 매개변인으로 가정한 불안과 심리적 경직성을 변화시키는 데 효과적이었다. 그러나 통증 및 통증간섭 감소에 대한 불안과 심리적 경직성 변화의 매개효과는 유의하지 않은 것으로 나타났다. 본 연구는 만성통증 노인에 대한 ACT의 효과를 검증한 연구라는 점에서 의의가 있다. Background: The population of the aged has been rapidly increasing worldwide, and about 50% of them are under chronic pain by irreversible degenerative diseases. This study aimed to verify the effectiveness of ACT (Acceptance and Commitment Therapy) on pain, pain interference, and life satisfaction in people with chronic pain. In addition, this study proposed that anxiety, depression, self-efficacy, psychological inflexibility in pain, pain catastrophizing and kinesiophobia are mediating the effectiveness of ACT. Methods: Participants of ACT program for this study comprised the elderly aged 65 and over who had been suffering from chronic pain for at least 6 months and reported their pain intensity of at least five on the VAS (Visual Analogue Scale, 0-10). During the sessions, experimental group participated in the ACT program designed by Stoddard and Wetherell(2011) and the control group received health education. After finishing eight sessions of each program, data from 25 participants in the experimental group and 27 in the control group were used for the final analysis. Results: The results showed that the ACT program is significantly more effective on relieving pain, pain interference, anxiety, and psychological inflexibility in pain than health education program. However, anxiety and psychological inflexibility did not have significant mediating effects on pain and pain interference. Conclusions: Finally, this study has verified the curative effect of ACT for elderly people suffering from chronic pain. Therefore, Acceptance and Commitment Therapy can be used for supplementary treatment for patients with degenerative disease.

This study is to find influence for 8-weeks combined exercise and the combined treatments of Gardenia intake to the body composition and Inflammatory related hormones in the Obese Middle Aged Women. To this purpose, 16 middle-aged obese females are divided to Gardenia+Excercise Group (n=8) and Gardenia Group (n=8). For 8 weeks each exercise is performed with 50~60% HRmax, 50% 1-RM. 0.08 g of the Gardenia is consumed per 1 kg of the body weight. The results of study are as under: 1. In the body composition change, the interaction effects show on%fat, fat mass, VFA and WHR. 2. In the blood lipid, the interaction effect doesn’t show. And, Gardenia + Excercise Group shows the significantly reduction of TC, TG and LDL-C. Gardenia Group shows the significantly reduction of LDC-C and the increase of HDL-C. 3. In the change of inflammation related hormones, the interaction effect shows in Leptin(p<.05). Gardenia+Excercise Group shows the significantly increase of Adiponectin and the significantly decrease of Resistin. And Gardenia Group show the increase of Adiponectin. According to the above results, Gardenia’s anti-obesity effect is shown to be positive, yet occures the reduction of fat-free mass. Therefore, to maintain the reduced body weight, the combination treatment of exercise and Gardenia is considered to be effective.
