  Background Self-control, self-defense self-efficacy, and mental resilience are fundamental psychological determinants of performance and competitive endurance in combat sports. However, scientific evidence on structured, evidence-based psychological intervention programs for professional female wrestlers remains limited. This study examined the effects of a psychological skills training (PST)-based intervention on self-control, self-defense self-efficacy, and mental resilience in professional female wrestlers. Methods A randomized controlled pre-test-post-test design was employed. Thirty-six professional female wrestlers (aged 18-25) were randomly assigned to a PST group (n = 18) or a control group (CG; n = 18). The PST group completed an 8-week structured psychological intervention alongside regular training, while the CG continued routine training only. Self-control, self-defense self-efficacy, and mental resilience were assessed pre-and post-intervention using valid and reliable psychometric scales. Data were analyzed via repeated-measures ANOVA, with effect sizes calculated. Results Significant group & times; time interactions were observed across multiple outcomes. A highly significant interaction emerged for perceived physical self-defense capacity (SP; F(1,34) = 56.525, p < 0.001, eta p(2) = 0.624) and for DP scores (F (1,34) = 9.360, p = 0.004, eta p(2) = 0.216). Among self-control subscales, significant interactions were found for inhibition (F (1,34) = 8.172, p = 0.007, eta p(2) = 0.194) and, more strongly, for initiation (F (1,34) = 14.157, p < 0.001, eta p(2) = 0.294). For mental resilience, highly significant interactions were detected for confidence (F (1,34) = 59.976, p < 0.001, eta p(2) = 0.638), control (F (1,34) = 32.486, p < 0.001, eta p(2) = 0.489), and persistence (F (1,34) = 32.709, p < 0.001, eta p(2) = 0.490). Overall, the intervention demonstrated medium-to-high effect sizes across psychological performance indicators. Conclusion These findings suggest that PST may serve as a useful complementary approach for enhancing self-control, perceived physical self-defense capacity, and mental toughness in professional female wrestlers. However, results should not be interpreted as evidence of improved competitive wrestling performance, technical success, or objectively measured physical self-defense ability, as these outcomes were not directly assessed in this study.

  Investigation of the relationship of cognitive performance, visual reaction time and agility parameters on football players

  Kıyıcı, Fatih; Demir, Okan

  The research aims to examine the relationship between cognitive performance, visual reaction time and agility parameters on football players. Twenty- five football players with an average age of 18-20 years (18.16 ± 0.68), who have been active for at least five years and who are in the Turkish U19 Super League participated in the study from the Turkish U19 Super League participated. Body composition (BODPOD), agility (Illinois test), visual reaction time (Witty Sem Microgate) and cognitive performance (Stroop Test) of the football players were measured. SPSS v23 was used in the analysis of the data and the significance level was taken as p&lt;0.05. The relationship between normally distributed data was examined with the Pearson Correlation Coefficient. According to the analysis of the data a significant positive correlation was found between cognitive performance and visual reaction time on football players. When the relationship between cognitive performance and agility parameter was examined, no significant relationship was found between the two concepts. There was a significant correlation and a negative correlation between visual reaction time and agility parameters. As a result, when height, body mass index and body fat ratio values increase on football players, visual reaction time increases and performance decreases. Likewise, when the body fat ratio increases, agility time increases and performance decreases.

  Futbolda sosyal medya iletişimi ve marka değeri: Trabzonspor ve taraftarları üzerine bir araştırma

  Okan Demir

  Bulunduğumuz yüzyılda futbol kitleleri peşinden sürükleyen, farklı kültürlere sahip insanları bir araya getiren bir olgu olarak ortaya çıkmıştır. Futbolun bu birleştirici özelliği ekonomiden siyasete kadar farklı alanlarda söz sahibi insanların ilgisini çekmiştir. Futbol gün geçtikçe büyüyen ve finansal olarak ciddi bir pazar haline gelmiştir. Bu pazarda yer alan ve kendini konumlandırmak isteyen futbol klüpleri gelirlerini artırmak, kurumsallığını sürdürmek adına marka değerlerini korumak zorundadır. Bunun için sürekli gündemde kalmak ve değişim ve gelişim süreçlerine uyum sağlamak diğer sektörlerde olduğu gibi futbol klüpleri için de ön plana çıkmıştır. Teknolojik gelişme ile paralel olarak-özellikl 21.yy'da- kitle iletişim araçlarında çok büyük değişimler meydana gelmiştir. Bu gelişmeler insanların iletişim ve erişim olarak kolayca ulaşabileceği ve kullanabileceği platformların oluşmasına yol açmıştır. Sosyal medya günümüzde bu platformların başında gelmektedir. Sosyal medya sayesinde çok kısa sürede çok sayıda insan ile iletişime geçmek ve onlardan geri bildirim almak ucuz ve kolay bir hale dönüşmüştür. Bu çalışmada Türkiye Süper Liginde mücadele eden köklü takımlarımızdan olan Trabzonspor'un yoğun rekabet ortamında marka değerini korumak için sosyal medya iletişimi sayesinde oluşturduğu etkileşim ile bu renklere gönül veren taraftarların ortaya koyduğu etkileşimin klübün marka değeri ve bileşenleri üzerinde etkisi araştırılacaktır.
