Abstract

Purpose: Sarcopenia is defined as a decrease in muscle mass, strength, and function with age that affects overall body function. We aimed to investigate the effect of combined training on body composition, balance, and muscle function in sarcopenia elderly. Research design, data, and methodology: Twenty-eight sarcopenia elderly (age 74.9&#x00B1;4.5 years) were randomly assigned to an exercise, EG (n=14), or a control, CG (n=14), group. The EG performed an intervention consisting of combined exercise training (60-75 min) for a total of 12 weeks, three times a week. The CG maintained their usual daily lifestyle during the intervention period. We measured body weight, body mass index (BMI), % body fat, free fat mass, balance ability, peak torque in shoulder, knee, and lumbar joints normalized for bodyweight in one second. Results: The EG showed improved body composition (i.e., BMI, fat-free body mass, fat mass; all p < 0.031, &#x03B7;<sup>2</sup> > 0.179), balance (i.e., right and left of static and dynamic balance and fast 10 m walk; all p < 0.049, &#x03B7;<sup>2</sup> > 0.152), and muscular function (i.e., 90&#x00B0;/sec and 180&#x00B0;/sec peak power per kg bodyweight, 90&#x00B0;/sec average power per kg bodyweight, 180&#x00B0;/sec total work, and 180&#x00B0;/sec endurance ratio; all p < 0.045, &#x03B7;<sup>2</sup> > 0.158). Conclusions: Combined exercise training improves muscle mass and strength, body composition, balance, and muscle function in sarcopenia elderly.

The purpose of this study is to investigate the relationship between regional attachment and expansion of fans according to the type of CSR activities of the club, and to examine influencing relationships among the types of CSR activities, regional attachment, and expansion of fans. Research design, data, and methodology: To achieve the purpose of the study, the survey was conducted on 150 home spectators of Seongnam Football Club, and the analysis of the data was conducted using SPSS Window Version 21.0. Correlation analysis, simple regression analysis, and multiple regression analysis were conducted to analyze the relationship between regional attachment and expansion of fans according to the types of CSR activities performed by the Seongnam Citizens Football Club. Results: As a result of the analysis, it was found that CSR activities had a statistically significant effect on regional attachment. In addition, CSR activities were found to have a statistically significant effect on expansion of fans. Finally, it was found that regional attachment had a statistically significant effect on the expansion of fans. Conclusions: Based on these results, CSR activities of the professional football club are considered an opportunity to build regional attachment. In addition, it is thought that the expansion of fans can be achieved through CSR activities.
