Bu çalışmada fiziksel etkinlik hizmetleri sunan fitness merkezlerinde hizmet kalitesinin müşteri memnuniyetine etkisinin incelenmesi amaçlanmıştır. Veri toplama aracı olarak, hizmet kalitesine yönelik Yıldız ve Kara’nın (2012) geliştirdiği QSport-14 ölçeği, müşteri memnuniyetine yönelik ise Cronin, Brady ve Hult’un (2000) geliştirdiği memnuniyet ölçeği kullanılmıştır. Veriler Antalya ilinde ticari olarak faaliyet gösteren 3 farklı fitness merkezinin müşterilerinden (n=227) elde edilmiştir. Ölçeklerin güvenirliklerini belirlemek amacıyla yapılan güvenirlik testi sonucunda QSport-14 ölçeğinin Cronbach Alpha değeri 0,849, müşteri memnuniyeti ölçeğinin Cronbach Alpha değeri ise 0,743 olarak bulunmuştur. Hizmet kalitesinin müşteri memnuniyeti üzerine etkisini belirleyebilmek için hiyerarşik regresyon analizi uygulanmıştır. QSport-14 ölçeğinin alt boyutları olan “personel”, “fiziksel özellikler” ve “program” değişkenlerinin müşteri memnuniyeti üzerine etkisi ayrı ayrı değerlendirilmiştir. Analizler sonucunda, fitness merkezlerindeki hizmet kalitesinin (ve alt boyutları olan personel, fiziksel özellikler ve program değişkenlerinin) müşteri memnuniyeti üzerinde anlamlı ve pozitif etkisi bulunmuştur (p<0,001). Bu alt boyutlardan, müşteri memnuniyeti üzerine en yüksek etki personel (β=,492) alt boyutudur, ardından program (β=,444) ve fiziksel özellikler (β=,432) gelmektedir. Diğer taraftan demografik değişkenlerin müşteri memnuniyeti üzerine herhangi bir anlamlı etkisi ise görülmemiştir. Bu sonuçlara göre, fiziksel egzersiz hizmeti sunan fitness merkezlerinde müşteri memnuniyeti sağlayabilmenin yolu (başta personel olmak üzere, program ve fiziksel özellikler yönüyle) hizmet kalitesini arttırmaktan geçtiği söylenebilir.

Internal marketing and organizational citizenship issues have recently begun to be studied more in the literature. This study aimed to examine the effect of internal marketing practices on the organizational citizenship behavior of employees in the sports sector. Data were collected by simple random sampling method using an online survey tool and was obtained from Antalya, Karaman, Kütahya, Izmir, Istanbul, and Muğla Provincial Directorate of Youth and Sport of employees (N = 224). As a data collection tool, the IM-11 scale developed by Yildiz and Kara (2017) was used to measure internal marketing, and the organizational citizenship behavior scale developed by Bolat, Bolat and Seymen (2009) was used to measure organizational citizenship behavior. Descriptive statistics, validity and reliability analysis, correlation analysis, and hierarchical regression analysis were used in the analysis of the data. The result of the analyses showed the significant and positive effect of internal marketing on organizational citizenship behavior. In other analyzes, while internal marketing had a significant and positive effect on the sportsmanship and civic virtue subscale of organizational citizenship behavior, no significant effect was observed on altruism, conscientiousness, and courtesy.

The purpose of this study was to examine whether the leisure involvement of adults who participate in fitness activities has an effect on positive and negative affect. The relational screening model, one of the quantitative research methods, was used. In this study, the “Leisure Involvement Scale” and the “Positive and Negative Affect State Scale” were used. Descriptive statistics, parametric tests such as Pearson's correlation test and simple regression analysis were used to analyses the data. In addition, validity and reliability analyses were carried out to determine the validity and reliability coefficients of the scales. It was found that leisure involvement and its sub-dimensions have an effect on positive and negative affect states. As a result, it was concluded that positive emotional states increased, and negative emotional states decreased in adult individuals who participated in leisure-time fitness exercise. Therefore, it shows that it can help adults cope with the negative emotions they encounter in their daily lives (stress, anxiety, burnout, depression, lack of self-esteem, social appearance anxiety, etc.).

Background/Objectives: The current study aimed to investigate the mediating role of injury anxiety in the relationship between mental training and flow state among wheelchair basketball athletes. Although mental training is known to be essential for enhancing athletic performance, the underlying mechanisms through which it affects psychological states such as flow have been studied very limitedly, especially in adaptive sports. Methods: The research was conducted using a correlational survey model within a quantitative research framework. The study sample consisted of a total of 153 elite male wheelchair basketball athletes competing in leagues in Türkiye. Hayes’ Process Macro Model was used to test the mediating effect in the analysis of the data. Results: The analyses revealed that mental training significantly reduced injury anxiety (β = −0.328, p < 0.001), accounting for 7.6% of its variance. Injury anxiety had a significant negative effect on optimal performance (β = −0.3380, p < 0.001). The direct effect of mental training on performance remained positive and significant (β = 0.4324, p < 0.001). Together, the variables explained 43% of the variance in optimal performance. The total effect of mental training was also significant (β = 0.543, p < 0.001). Conclusions: In conclusion, the findings of this study reveal that mental training plays a significant role in both reducing injury anxiety and enhancing optimal performance among wheelchair basketball players. It was determined that injury anxiety functions as a mediating variable in the relationship between mental training and flow.

Introduction: Mental performance skills are recognized as critical for success in combat sports, yet the underlying mechanisms through which they influence performance remain poorly understood. This study examines the mediating role of mental toughness between mental performance skills and athletic performance within the framework of Conservation of Resources Theory. Method: This quantitative research employed a correlational survey model. The study included 470 combat sport athletes (243 male, 227 female) from various universities in Türkiye. Participants completed the Mental Performance Skills Scale, the Mental Toughness Inventory, and the Athletic Performance Scale for Combat Athletes. Data were analyzed using Pearson correlation analysis and Structural Equation Modeling. Model fit indices were calculated as CFI = 0.983, TLI = 0.981, RMSEA = 0.08, and SRMR = 0.07. Results: Correlation analysis revealed positive and significant correlations among all variables ( r = 0.394–0.445, p < 0.001). According to Cohen’s conventions, these values represent medium-to-large effect sizes. Structural equation modeling results indicated that mental performance skills had significant direct effects on athletic performance ( β = 0.353, p < 0.001) and on mental toughness ( β = 0.483, p < 0.001), and that mental toughness significantly predicted athletic performance ( β = 0.361, p < 0.001). Bootstrap analysis confirmed that mental toughness served as a significant mediator, as the indirect effect [ β = 0.174, 95% CI (0.111, 0.204)] did not contain zero. The direct effect ( β = 0.353, p < 0.001) remained significant after accounting for the indirect pathway. Conclusion: In conclusion, mental performance skills strengthen mental toughness, and this enhanced mental toughness plays a significant mediating role in improving athletic performance. Structured mental skills training can improve not only competition results but also fundamental psychological capacities such as stress management and coping with challenging conditions.

This study examined the effect of job stress on the performance of sports coaches. Sports coaches who worked in the Directorate of Youth and Sport at Antalya, Kutahya, Karaman, and Mugla Provinces, in Turkey, participated in the study (n = 168). As a data collection tool, the job stress and job performance scales adapted by Ornek (2017), from Turkmen’s (2015) research were used. For the reliability of the scales, Cronbach's Alpha coefficient was determined and correlation and hierarchical regression analyses were performed to determine the relationships among the variables. Correlation analysis showed that the performance variable was significantly and negatively correlated with all stress sub-dimensions (p < .01). The strongest relationship was with the management structure (r = -.376). In addition, the performance variable was significantly and negatively correlated with the age variable (r = -.163). The performance variable was significantly and positively correlated with the income variable (r = .171) and the educational degree variable (r = .171). According to the hierarchical regression analysis, the performances of the sports coaches were not affected by any of the demographic variables, but were affected significantly and negatively (β = -.338; p < .001) by stress.
