Abstract
The purpose of this study was aimed to distinguish between excessive use and fatigue-sensitive muscles by analyzing the contraction characteristics of the lower limb muscles with tensiomyography (TMG) before and after the competition in female youth national badminton players. Before and immediately after the badminton game, the maximum displacement, contraction time and contraction velocity of the quadriceps and hamstring muscles were evaluated by TMG. As a result of the study, the maximum displacement (Dm) was not significantly changed in all individual skeletal muscles, but the maximum displacement of the dominant semitendinosus muscle showed an increase level close to the critical value immediately after the competition (p=0.086). Immediately after the game, the change in contraction time (Tc) significantly decreased in the dominant vastus medialis and non-dominant vastus lateralis muscles (p<.05), and the contraction velocity (Vc) was significantly faster in the dominant medial lateral muscle (p<0.05). In conclusion, the muscle tension of the semitendosus muscle was weakened by fatigue, and the dominant medial and non-dominant vastus muscles were excessively tense. Therefore, in order to prevent injuries of female adolescent badminton players, interventions were needed to promote the recovery of the dominant semitendinosus muscles and to relax the hypertensive tension of dominant Vastus Medialis and non-dominant Vastus Lateralis muscles immediately after the game.

Abstract
The purpose of this study is to analyze the current status of decent job employment and the factors that affect decent job employment of sports studies graduates. For research analysis, data from the Graduates Occupational Mobility Survey (GOMS) from 2015 to 2019 were used. The subjects of the study were a total of 61,268 graduates(1019 graduates majoring sports studies) from 4-year university. To analyze the data, frequency analysis, chi-square test method, t-test, logistic regression analysis were performed. The results of this study are as follows. 1) The ratio of decent job employment of sports studies graduates was lower than that of all majors. 2) The ratio of formal employment paths is the highest for the decent job employment of sports studies graduates, but the ratio of the informal employment paths of sports studies graduates is higher than that of all majors. 3) Gender was found to have an effect on the decent job employment of sports studies graduates, 4) It was found that the number of taking employment class in academy, and the number of participation in corporate recruitment briefings as job preparation behaviors were significant variables for a decent job employment of sports studies graduates. However, the frequency of participation in the employment support program of sports studies graduates was generally lower than that of all majors. 5) As a pre-management for employment, the TOEIC score influenced the decent job emplyment of sports studies graduates. But the number of licenses had a negative effect on employment in decent jobs. In summary, this study emphasizes that there is a need for more focus on job quality in employment guidance, such as employment programs tailored to majors for sports studies students. This study is significant in that it is an early study that analyzed the factors of decent job employment for sports studies graduates.

Abstract
Mitochondria are intracellular organelles, involve in regulating cellular homeostasis through various signaling pathways. Damaged mitochondria are closely related to chronic diseases, and have been actively studied for the patho-physiologic conditions. Mitophagy is a cellular mechanism of action that plays an important role in maintaining and improving cellular functions by selectively removing damaged mitochondria and exercise regimen is known to regulate mitochondrial quality control including the process of mitophagy. In this study, the effect of treadmill exercise for 1 week on the in vivo mitophagy of skeletal muscle was analyzed using mt-keima transgenic mice. As a result, the higher red fluorescence (pH 4.0; excitation: 561nm, emission range: 570-695nm) ratio was observed on confocal microscopy in the exercise (EX) group vs. the control (CON) group. These results were also consistent with the data that observed protein levels which are known to be induced during mitophagy. Therefore, the effect of exercise intervention on mitochondrial quality control can be more accurately verified through validation using the in vivo mitophagy evaluation model, mt-Kiema mice.

Abstract
The purpose of this study was to explore the changes that the COVID-19 pandemic had brought to the lives of student-athletes and to provide suggestions for possible support and improvement. Research participants were seven rhythmic gymnasts at S university located in the city of S. We used photovoice, a participatory action research strategy, with research stages categorized in the order of orientation, photovoice execution, and focus group interview. In the analysis of collected qualitative data, the lives of student athletes amid the COVID-19 pandemic were categorized into the themes of ‘growth in change’ (positive change) and ‘darkness in change’ (negative change). As sub-themes for ‘growth in change’, ‘students, not athletes’, ‘my existence’, and ‘various new experiences’ were derived, while ‘darkness in change’ included ‘unfamiliar and uncomfortable environment’, ‘unplannable future’, and ‘pause without deadline’. This study is meaningful in that it facilitated active involvement of the participants in the research process and utilized the photos they had taken, which allowed insights into the life changes experienced and perceived by student-athletes in great detail and depth. Based on the results of this study, we discussed various challenges student-athletes are facing amid the current pandemic and offered some suggestions for future improvement and support.

Abstract
The purpose of the study was to comprehensively examine the relationship between physical activity participation of people with disabilities and their mental well-being through a meta-analysis. The analysis included academic journals and dissertations that have analyzed mental well-being for people with disabilities participating in physical activity in Korea from 2005 to 2020. After a total of 76 research papers were selected during the preliminary investigation, the papers that didn’t have clear indication which were the information required to compute the effect sizes, were excluded during the review of the individual paper. The remaining 22 papers were used to extract 372 effect sizes for the analysis. The random-effects model of the meta analysis was used along with the variable-level and research-level analyses at the same time as the analysis methods. The conclusions drawn through the above process were as follows. First, the positive effect sizes of the independent variables on mental well-being were exercise addition (g=1.605), social support (g=1.533), and life sports participation (g=1.522), while the negative effective sizes were leisure constraint (g=-.669) and loneliness (g=-.440). Second, as a result of the research level analysis, the overall effect size of the 22 studies was found to be g=.525. Third, as a result of the publication bias review, 372 individual studies that verify the relationship between mental well-being of the people with disabilities and their participation in physical activities only suggested the high effect sizes. After the adjusted effective sizes were calculated through the Trim and Fill method, fhe Funnel Plot became symmetrical when a total of 71 individual studies were inserted. Also, the average effect size was decreased from g=.419 to g=.298.

Abstract
The purpose of this study is to understand the structural influence of the resilience of disaster resilience of ski resort workers perceived by ski consumers on consumer behavior, thereby promoting the ski resort industry, which is shrinking due to COVID-19, as well as the efficient promotion of tourism and sports industries. It is intended to provide basic data for preparing management plans. In order to achieve this purpose, we conducted a survey on the awareness of disaster resilience of ski resort workers targeting users of High1 Resort, and conducted structural equation model analysis using SPSSWIN 23.0 and AMOS 23.0 to derive the following results. First, the disaster resilience of ski resort workers had a positive (+) effect on customer satisfaction, all sub-variables, controllability, sociality, and positivity. Second, resilience to disaster resilience of ski resort workers had a positive (+) effect on revisit by controllability and sociality, which are sub-variables, but positivity did not. Third, customer satisfaction for the resilience efforts of ski resort workers had a positive (+) effect on revisit. Therefore, from the management point of view, ski resort should be aware that the resilience of ski resort workers under disaster situations such as COVID-19 has a positive effect on customer behavior such as consumer satisfaction and revisit, and should establish specific program for resilience to disasters for ski resort workers.
