PURPOSE: This study examined the distribution dynamics and proposed determinants, including morphological measurements, clinical laboratory tests, and lifestyle factors among young Korean men aged 20 to 29 years with the coexistence of age-related loss of skeletal muscle mass and obesity (CALSMO). METHODS: Six hundred and sixty-six participants were divided into two groups based on their skeletal muscle mass index, with 12 individuals categorized in the CALSMO group and the remaining 654 in the normal group. The proposed determinants variables consisted of three main components: morphological measurements, clinical laboratory tests, and lifestyle factors. The morphological measurement variables were height, weight, body mass index, waist circumference, and skeletal muscle mass index. The clinical laboratory tests were fasting glucose, triglyceride, total cholesterol levels, and systolic and diastolic blood pressure. The lifestyle factors considered were alcohol consumption and tobacco use. Complex sampling analysis was performed for the evaluation. RESULTS: The distribution dynamics were determined to be 1.81(1.02-3.18) %. Morphological factors, such as height, weight, body mass index, waist circumference, and skeletal muscle mass index, showed significant differences (p < .05). The clinical laboratory test variables, specifically the fasting glucose, triglyceride, and total cholesterol levels, also exhibited significant differences (p < .05). The lifestyle factor, alcohol consumption, also showed a significance (p < .05). CONCLUSION: This study provides insights into the distribution dynamics. The proposed determinants in young Korean individuals with CALSMO are height, weight, body mass index, waist circumference, skeletal muscle mass index, fasting glucose, triglyceride, total cholesterol levels, and alcohol consumption.

Objectives: The purpose of this study is to evaluate weight change and analyze adverse events in post-menopausal obese women with Gamitaeeumjowee-tang for weight loss. Methods: A retrospective chart review was conducted for medical records of 115 post-menopausal obese women (body mass index, BMI≥25 kg/m²) who were administered with Gamitaeeumjowee-tang for 12 weeks for the purpose of weight loss. Weight, skeletal muscle ratio and BMI changes were compared before and after the program. Adverse events were evaluated by causality, severity and system-organ classes. Results: A total of 115 patients were included in this study. The average total weight loss in post-menopausal women was 5.72±2.04kg(p<0.001) and the average weight loss rate was 8.06±2.70%(p<0.001). After the 12-week program, the body fat rate was significantly decreased(3.76±2.20%)(p<0.001) and the skeletal muscle ratio was significantly increased(2.07±1.24%)(p<0.001). There were no significant differences in weight loss, skeletal muscle ratio change and body fat rate change depending on the number of hospital visits. Insomnia was frequently reported throughout the period, and no serious adverse events were reported. Conclusions: This study showed the potential that weight management treatment with Gamitaeeumjowee-tang could be a good way to lose weight of post-menopausal obese women without serious adverse events. Continuous well designed clinical studies are needed.

Chronic obstructive pulmonary disease(COPD) is characterized by a not entirely reversible limitation in the airflow. An airflow limitation is progressive and associated with an abnormal inflammatory response of the lung to gases and harmful particles. In COPD, the weight loss is commonly observed and there is a negative impact on the respiratory as well as skeletal muscle function. The pathophysiological mechanisms that result in weight loss in COPD are not fully understood. However, the mechanisms of weight loss in COPD may be the result of an increased energy expenditure unbalanced by an adequate dietary intake. The commonly occurring weight loss and muscle wasting in COPD patients adversely affect the respiratory and peripheral muscle function, the exercise capacity, the health status, and even the survival rates. Therefore, it is very valuable to include management strategies that the increase energy balance in order to increase the weight and fat free mass. A Better understanding of the molecular and cellular pathological mechanisms of COPD can improve the many new directions for both the basic and clinical investigations. The Nutritional supply is an important components of a multidisciplinary pulmonary rehabilitation program. Future studies combining an exercise program, the role of anabolic steroids, nutritional individualization, a more targeted nutritional therapy, and the development of new drugs including anti-cytokines is needed for the effective management of COPD.

The purpose of this study was to investigate the scapulothoracic joint movement between different weight bearing contributing to effective bench press exercise. Ten male subjects participated in this study. All subjects were tested on the flat bench press machine which modified weight (50% and 70% of 1RM) and subjects were performed two different conditions(none protraction condition and protraction condition). Weight bar height and vertical velocity, EMG activation was measured using 3D motion capture system and wireless EMG analysis system. As the results, none protraction condition showed that it is more concentrate better pectoralis major muscle activation than protraction condition and middle pectoralis major, anterior deltoid and triceps brachii was significant higher integrated EMG in 70% of 1RM condition. In conclusion, limited scapulothoracic joint movement was more effective activated pectoralis major muscle all the weight through, while we could not find that it was not affected integrated EMG on eight muslces related to shoulder complex between scapulothracic joint movement conditions.

This study was carried out to investigate distribution of obesity, body composition, weight control and dietary behaviors, and to analyze the relationship between Body Mass Index (BMI) and physical characteristics, body composition and dietary behaviors by anthropmetric measurement and questionnaires. The 199 study subjects were divided into 3 age groups; 30's (78), 40's (77) and 50's (44) and 4 groups by BMI ; under weight (4.5%), normal (51.3%), over weight (26.1%) and obese (18.1%). Amount of skeletal muscle, body water, mineral and body fat were significantly increased with BMI. There were especially significant increase skeletal muscle 5.3 kg ($19.1\;{\rightarrow}\;23.5\;kg$), body water 5.3 kg ($26.3\;{\rightarrow}\;31.6\;kg$) and fat 15.2 kg ($11.2\;{\rightarrow}\;26.4\;kg$) from under weight to obesity group, respectively (p < 0.01). There were significantly decreased in the ratio of body water (10.3%), protein (2.7%) and body mineral (1.1%) from under weight to obesity, but significant increase 14.1% in body fat (p < 0.001). About 44.4% of under weight group and 40.1% of normal group and 50% of over and obesity group had dissatisfaction on their body images. Most of the women were concerned about their body images and experienced weight control. Dietary behavior scores of obesity group were significant lower than the other four groups (p < 0.001). There were significant positive correlation between BMI and body water (r = 0.62), protein (r = 0.52), skeletal muscle (r = 0.63), body fat (r = 0.91) and WH ratio (r = 0.91), respectively (p < 0.001). The correlation between BMI and body fat and WH ratio were much higher than the correlation between weight and fat and WH ratio.

This study was designed to examine the effects of electroacupuncture and treadmill exercise on the improvement of muscle atrophy and Brain-Derived Neurotrophic Factor (BDNF) expression in an ischemic stroke model induced by middle cerebral artery occlusion. This study selected 120 Sprangue-Dawley rats, divided them into six groups, and assigned 5 rats to each group. Experiments were conducted for 1, 3 days and 1, 8 weeks, respectively. In each group, changes in weight of muscle and relative muscle of tibialis anterior muscle, histologic observations, and BDNF expression were observed and analyzed. For the changes in muscle weight of unaffected and affected sides of tibialis anterior, muscle atrophy was expressed in an affected side 3 days after ischemic stroke was induced. There was a statistically significant difference in Group VI 1 and 8 weeks after ischemic stroke was induced, compared to Group II (p<.05). For the changes in relative muscle weight of unaffected and affected sides of tibial anterior muscle, there was significant decrease in each group 3 days after ischemic stroke was induced, compared to Group I, while there was a statistically significant increase in Group VI 1 week after ischemic stroke was induced, compared to Group II (p<.05). For neurologic exercise behavior test, Group VI generally had the highest score, compared to other groups. The results of the behavior test suggests that 8 weeks after ischemic stroke was induced, Group VI improved in degeneration and inflammation of muscle fiber and decreased in destruction of nerve cells and cerebral infarction, thus indicating a similar state of muscle fiber and brain tissue in Group I. In immunohistochemical observations, Group 1 week showed increase in BDNF. Based on these results, electroacupuncture and treadmill exercise may improve muscle atrophy and change in BDNF expression of ischemic stroke rats and contribute to the improvement of exercise function.
