Purpose The purpose of this study is to investigate the comparison of peak resultant force in taekwondo body dollyeochagi in accordance with Jejariditgi existence and the position of kicking leg. Methods Twelve students who majored taekwondo participated in this experiment. They have a forth dan(degree) black belt in taekwondo. The peak resultant force was measured 12 times(2 jejariditgi existence × 2 position of kicking leg × 3 times). Two-way ANOVA with repeated measures was used to analyze the data. Results There was significant difference in interaction effect of peak resultant force in taekwondo in accordance with jejariditgi existence and the position of kicking leg. And there was significant difference in main effect of peak resultant force in taekwondo in accordance with jejariditgi existence and the position kicking leg. Higher peak resultant force was shown in body dollyeochagi with jeariditgi as compared with non jejariditgi. And higher peak resultant force was shown in rear kicking leg as compared with front kicking leg. Conclusions The results show that jejariditgi is a factor affecting the peak resultant force. Comparison of peak resultant force in taekwondo body dollyeochagi in accordance with jejariditgi existence and the position of kicking leg will provide strategies for coaches and athletes to perform improved taekwondo dollyeochagi.
Purpose The study examined the effects of a 12-week high intensity circuit training (HICT) on abdominal fat, physical fitness, blood lipids, and insulin resistance in middle-aged obese women. Methods Thirty obese women, aged 32-48 yrs, were recruited and randomly assigned to either HICT group (TR; n = 15) or control group (CON; n = 15). Subjects in the TR group participated in HICT of which resistance exercise and aerobic exercise were performed with a duration of 40 min/session and 3 sessions/wk for 12 weeks, whereas subjects in the CON group were asked to maintain their normal life patterns. Dependent variables included abdominal fat area, body composition, physical fitness, blood lipids profiles, and insulin resistance index. Analysis of variance with repeated measures with Bonferroni corrections was used to compare the outcomes between two groups. Results Main findings of the present study were as follows: 1) compared to the CON group, the TR group had significant reductions in overall (i.e., body mass index and percent body fat) and abdominal obesity (i.e., waist circumference, total abdominal fat area, visceral fat area, subcutaneous fat area, and visceral fat area-subcutaneous fat area ratio), 2) compared to the CON group, the TR group had significant improvements in health-related physical fitness (i.e., muscular strength, muscular endurance, muscle power, flexibility, balance, and cardiorespiratory endurance), and 3) compared to the CON group, the TR group had significant improvements in fasting lipids, glucose, insulin, and insulin resistance. Conclusions The current findings of the study suggested that HICT would be an effective exercise intervention to improve metabolic complications associated with obesity and poor physical fitness in obese middle-aged women.
Purpose This study was designed to develop a curriculum for pre-service golf coaches at universities to enhance the coaches’ competencies to counsel athletes on the field. Methods This study was conducted in accordance with the revised and supplemented procedures for the national competency standard (NCS) based curriculum development outline under the level of application of individual instruction-level classes among the types of curriculum development. Results The results were as follows: First, the elements of the counseling competence were guided by conflict resolution counseling, psychological skills training, guidance counseling, coordination and Intervention, and relationship formation. Second, the curriculum was adopted as a curriculum for sports psychology, theory and practice of counseling, counseling practice and super-vision, and psychological skills training, and non-disciplinary activities were participation in group and personal counseling, and an open counseling case study. Third, the feasibility of the curriculum was calculated in the range of 0.8 to 1.0 for all areas to be reasonable. Conclusions The results of this study have structured the counseling competencies required for pre-service golf coaches. Based on this, the results of the study suggest counseling courses in the curriculum of university. This is expected to ultimately seek to improve the coaching field by enhancing the capacity of the coaches.
Purpose The purpose of this study was to investigate how the educational zeal of mothers with winter sports students in secondary schools appears on the network charts. Methods It lasted 28 days from February 6 to March 5, 2017. Starting with a description of the QNA, all interviews were recorded on a tape recorder to carry out the project. Data analysis were divided into four areas(Family, Friend, School, etc.) and 13 associative words(enthusiasm, intelligence, performance, entry, success, sacrifice, atmosphere, polarity, competition, vicarious, satisfaction, economic power, anxiety, stress) to attach associative word stickers according to color. Results As a result of inducing arbitrary interpretation of the network subject's educational network, it was possible to analyze the factors affecting mothers' sports education in three dimensions. In addition, although there is not much difference in areas around "I" on sports education charts, the distance between associative words and network charts has gradually moved away from the same person as their children go on to school. Conclusions The methodological significance of this study has been found to be very useful in visualizing an individual's educational network by utilizing qualitative network analysis and in understanding the characteristics associated with education.
Purpose The purpose of this study is to look into the life of MTB college athletes before and after their college entrances through long-term longitudinal narrative inquiry and investigate how the career exploration after graduation is conducted in a contextual way. Methods For this study, four MTB college athletes who entered the university as specialists are selected as research participants, and their life and career are examined through a long-term longitudinal narrative inquiry. Results As a result, the life and career of MTB college athlete appear as follows. First, MTB college athletes entered MTB because of 'self - will' or 'influence of family and acquaintances' and the motivation is 'extension of hobbies', 'college entrance', etc. Second, the MTB college athletes' training and goals are set in the 'college entrance examination', which means the entrance to higher college. Third, MTB college athletes' college life is closely related to 'management and support system for college athletes', and the career search for them is based on 'the prospect as a player' and 'professional prospect of MTB athletes’. However, MTB college athletes showed their plan B to prepare for their uneasy future or to retire. Conclusions In the end, the MTB college athletes came to think about life and career on the narrow stage of unpopular sports and was seen coming down from the narrow stage of unpopular sports. Based on these results, this study presents critical discussions about their life and career of MTB college athletes and seeks implications for the school elite sports in Korea.

Methods Participants were five Taekwondo athletes in this study. They were consisted of offenders, a accuser, and a victim. The head coach of the team asked for counseling to resolve the conflict. Data was collected with quantitative, qualitative data, and group dynamics. The group counseling program was conducted for 90 minutes a week for eight weeks. Results The results are as follows. First, (application process) the 8-week Self-Assertiveness Training based on Solution-Focused was assessed to be applied step by step and systematically. Second, (qualitative evaluation) as a result of analyzing the observation journal and the interview data, the participants experienced the change of attitude and thought of group members in a short period of time by focusing on enhancing self-assertiveness. Third, (quantitative evaluation) self-assertiveness and attitude of school violence measured by questionnaires were higher in post-survey than pre-survey. In addition, participants' satisfaction with the program was found to be very positive. Discussions and Suggestions Self-Assertiveness Training based on Solution-Focused was found to have a significant effect on conflict resolution among the student-athletes who have experienced violence in sport. This programs was expected to increase the value of use in the sport field. Based on this case study, We suggested for future research.
Purpose The purpose of this study was to develop a Korean Life Skills Scale for Sports (KLSSS) that original version is the LSSS developed by Cronin and Allen (2017). Methods The subjects were 899 middle school and high school students. The measurement tool was used with LSSS. The validation of KLSSS followed a three-stage of validation procedure; substantive stage, structural stage, and external stage. The result is as follows. Results First, In the substantive stage, KLSSS consisted of 47 items with 8 factors. As a result of the item clarity test, it was confirmed that all the items were appropriate. Second, in the structural stage, KLSSS was explored and confirmed as 5 factors and 18 items. Third, in the external stage, KLSSS showed discrimination and convergent validity. Conclusions KLSSS is composed of 5 factors and 18 items. The factors are teamwork (TW), goal setting (GS), time management (TM), social skills (SS), and leadership (LD). This scale can be used to obtain information on life skills in school physical education or sports.
Purpose The purpose of this study is to explore the trend of K league exodus and its factors. Methods Qualitative case study was conducted by selecting 9 footballers and 7 their agents as the participants who have migrated from South Korea to China and the Middle East. Results The factors of migration were categorized as three push and pull factors such as economy (individual income and club's profit), policy (employment for foreign and military service) and environment (markets in home and abroad). To understand sport migration in the economic factor, there should be the environmental condition (overseas market) to pay high salaries and transfer fee to individuals and their clubs, and at the same time, the domestic market should be relatively poor environment. In addition, this study overcame limitations of economic and environmental factors by classifying Asian quota system and military service into political factor, and found the specificity (local context) of K league. Conclusions In conclusion, this study can be regarded as the first empirical work on sport labor migration in Korea and valuable as basic data of follow-up studies.
Purpose The purpose of this sequential mixed-method study is to compare the levels of Moderate to Vigorous Physical Activity (MVPA) between the students with intellectual disabilities and students without disabilities in different types of inclusive physical education classes and to understand why different levels of MVPA occur. Methods For this purpose, 17 students with intellectual disabilities and 102 students without disabilities participated in this study, and the levels of MVPA in inclusive physical education classes were accessed using thee dimensional accelerometers. The collected data were analyzed using independent sample t-test. To understand the different levels of MVPA identified in quantitative analysis, four teachers were interviewed. Results Results showed that different levels of MVPA were found in inclusive physical education classes, and this is because the students with intellectual disabilities had participation constraints and teachers did not have knowledge to deal with those constraints. Considering gender difference, only different levels of MVPA were found among male students, which could be stemmed from few opportunities of cooperative works between male students with intellectual disabilities and male students without disabilities. Considering types of inclusive physical education classes, significant different levels of MVPA were identified in tee ball classes. The reason for this could be that the rule of tee ball is too complicated and too many team tasks for the students with intellectual disabilities to understand and to execute. Conclusions Based on the results, practical teaching strategies to increase levels of MVPA of the students with intellectual disabilities are provided in the discussion section.
Purpose The purpose of this study was to investigate differences among perfectionism, anxiety, and aggression in contact and non-contact sports and verify the structural relationship model of perfectionism, anxiety, and aggression in the field of sports. Methods Male college athletes (N=299) participated in the study and perfectionism, anxiety, and aggression questionnaires were utilized after their verification of validity and reliability were conducted. The descriptive statistical analysis, the multivariate analysis, the correlation analysis, the structural equation analysis, and the multi-group analysis were conducted. Results The results are as follows: First, the level of perfectionism, anxiety, and aggression were significantly different between contact and non-contact sports (F=4.316, p<.001). Additionally, subfactors of aggression such as hostility, physical aggression, and verbal aggression factors in contact sports showed a higher average than non-contact sports. Second, perfectionism positively affected anxiety (t=6.936, p<.001) and anxiety positively affected aggression (t=3.380, p<.001). Moreover, the complete mediation effect of anxiety was found in the path from perfectionism to aggression (β=.152, p<.01). Finally, we compared path coefficients between contact and non-contact sports. As a result, positive causal relationships was indicated in the path from anxiety to aggression (β=.511, p<.001) in contact sports. However, it was not discovered in non-contact sports (β=.149, p>.05). Conclusions In conclusion, perfectionism causes anxiety and anxiety is a mediator leading to aggression in sports. Such effect is more predictable and observable in contact sports in which aggression is more favorable and encouraged. Implications and suggestions for future research are discussed.
