The purpose of this study was to implement Six Sigma Management Models in the Turkish National Soccer Team. Material and methods: 24 matches of the Turkish National Soccer Team constituted the sample of research. The DMAIC method was used in this study. For statistical analysis of research data, IBM SPSS 18.0 for Windows and Minitab 17 statistical software program were used. As statistical techniques, brainstorm, fishbone, chi-square correlation analysis, Spearman correlation test, process capability analysis and control charts were used, which were the six sigma tools. The numerical values obtained were tested at P < 0.01 and P < 0.05 significance levels. Result: As a result of the research, a statistically significant correlation was found among the match outcomes of the Turkish National Soccer Team and the game formation (P = 0.04), the positive shoot rate (P = 0.03), the positive defence rate on the first zone (P = 0.00) and the positive defence rate on the second zone (P = 0.00). As a result of the improvement, the z bench value for the positive defence rate on the first zone was increased from 0.47 to 0.59. Conclusion: It can be said that the Six Sigma Management Model is applicable for coaching or training in soccer.Master Thesis Spor Liselerinde Öğrenim Gören Öğrencilerin Beden Eğitimi Dersine Karşı Tutumlarının Sportmenlik Davranışlarına Olan Etkisinin Incelenmesi(2025) Çakır, Eren Bora; Terekli, Mustafa SerdarThis study was conducted in order to examine how the interest of students studying in sports high schools in physical education and sports lessons, the way they perceive the lesson and their attitudes towards the lesson shape and affect their sportsmanship behavior. The research was conducted with 210 participants studying at official sports high schools affiliated with the Ministry of National Education in Istanbul between 01/10/2024 and Dec 25/11/2024. SPSS (Statistical Package for Social Sciences-IBM, Chicago, IL, USA) program was used in the statistical analysis of the data obtained in the research. According to the results of the study, it was found that gender did not make a significant difference on the students' sportsmanship behaviors. Differences in sportsmanship attitudes were found according to the class level; especially 9. and 12. Attitudes of grade students, 10. and 11. it has been observed that it remains at a lower level compared to classroom students. It has been observed that the maternal education level has a significant effect on the students' sportsmanship behaviors, and it has been determined that the children of mothers with undergraduate and graduate education levels exhibit positive attitudes. On the other hand, no significant difference was found in terms of the father's educational level or sports playing status. It has been found that students whose mothers do sports have higher sportsmanship and physical education lesson attitudes compared to the children of mothers who do not do sports. In the regression analysis results, it was found that cognitive activity has a significant and positive effect on sportsmanship behaviors, while affective and behavioral elements of activity are not significant. It has been determined that general attitudes related to physical education lessons contribute to the development of sportsmanship awareness and behavior. These findings show that the elements that will increase cognitive awareness should be emphasized in the content of physical education courses in sports high schools and that family participation is an important factor in the process of creating sportsmanship awareness.Article Cleats on, Battle Real: Sustainability and Gender Equality in Women’s Football(Frontiers Media SA, 2026) Aksakal, Nalan; Ornek, Serda; Erkan, Mert; Besiktas, Murat Yalcin; Terekli, Mustafa SerdarObjective This study aims to examine the rise of women's football in Turkey and the challenges faced by female footballers both on and off the field from the perspectives of gender and sustainability.Methods Conducted with a phenomenological design, the study involved semi-structured interviews with 18 female footballers playing in the Super League between June and September 2025, using a snowball sampling method. The data were analyzed thematically.Results The findings revealed that the experiences of female footballers are shaped at the intersection of individual motivation, environmental support, and structural inequalities. Participants indicated that gender biases, economic constraints, and lack of media visibility limit their career development. Inadequate facilities, scarcity of female coaches, and limited professional opportunities were also identified as key barriers.Conclusion Women's football is not only a sporting activity but also a social arena with the potential to foster gender equality and sustainable development. The development of inclusive strategies by the Turkish Football Federation and clubs-such as equal pay policies, sponsorship support, female coach training programs, and female-friendly facility arrangements-is critically important for the sustainable growth of women's football.Article An Analysis of Psychological Resilience Levels Among Judo Coaches According to Selected Demographic Factors(Idokan Poland Association, 2025) Beşiktaş, M.Y.; Terekli, M.S.Background. Psychological resilience is a crucial personal trait that enables individuals, especially those in high-stress professions like coaching, to adapt and thrive in the face of adversity.

Data were collected using the “Psychological Resilience Scale for Adults” [Friborg et al. 2003; Basim, Cetin 2011] and a “Personal Information Form.” Statistical analyses were conducted using SPSS 24.0, including independent samples t-tests, one-way ANOVA, and Eta squared analysis to assess the influence of demographic actors on resilience levels. Results. The findings indicated significant differences in psychological resilience levels based on gender, marital status, age, educational attainment, coaching experience, income level, and coaching certification level.

Identifying individual characteristics that contribute to coaching efficacy is especially important in high-demand sports like wrestling. This study aimed to examine relationships between self-efficacy, psychological resilience, and proactive personality among wrestling coaches, and to determine the predictive roles of resilience and proactive personality on coaching self-efficacy. Methods A quantitative relational survey design was employed. The sample included 116 active wrestling coaches from Eskişehir, Kütahya, Tokat, and Konya. Data were collected using the Coaching Efficacy Scale II, Psychological Resilience Scale III-R, and Short Proactive Personality Scale, all adapted into Turkish. Analyses were performed with SPSS 23.0, including Pearson correlation, multiple regression, one-way ANOVA. Results Significant positive relationships were found between coaching self-efficacy, psychological resilience, and proactive personality. Multiple regression analysis indicated that psychological resilience (beta = .42) and proactive personality (beta = .38) significantly predicted coaching self-efficacy, collectively explaining 46% of the variance (R = .68, R-2 = .46, p < .001). Conclusion Enhancing psychological resilience and proactive personality is crucial for strengthening wrestling coaches' self-efficacy perceptions. Improving these psychological resources can enhance professional effectiveness, leadership behaviors, and positively influence athletes. These findings offer valuable implications for coach education programs and applied sport psychology interventions.
