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.

Background: Nutritional habits are a critical factor influencing the performance and recovery of professional athletes. Understanding how demographic variables affect nutrition-related attitudes is essential for developing targeted interventions. Objective: This study examined the nutritional attitudes of professional female volleyball players in Türkiye based on various demographic characteristics. Methods: The study included 386 licensed female volleyball players from the Turkish Women's Volleyball Super League, First League, and Second League. Data were collected using a demographic questionnaire and the Attitude Scale for Healthy Nutrition. Normality was assessed using the Kolmogorov-Smirnov test and skewness-kurtosis values. Statistical analyses included t-tests, ANOVA, LSD post-hoc tests, and partial correlation. Results: Significant differences in nutritional attitudes were found based on league level, smoking status, years of experience, and income level (p < 0.01). No significant differences were observed based on education level. Among the sub-dimensions, the malnutrition component showed no significant differences across most variables. Super League athletes scored significantly higher in nutritional knowledge and positive nutritional behaviors. Conclusion: The nutritional attitudes of professional volleyball players vary considerably according to key demographic factors. These findings highlight the importance of targeted nutrition education, particularly for lower-league athletes, to enhance performance and reduce disparities in nutritional knowledge.

Background The existing research on Muay Thai sports has focused predominantly on the physiological effects of training, with limited attention devoted to the study of quality of life, love of life and self-control. The present study examined the effects of Muay Thai exercises on quality of life, love of life and self-control scores in healthy male subjects. Methods The present study comprised 50 healthy sedentary male subjects. The subjects were randomly divided into two groups: one group engaged in Muay Thai training (MTT), while the other group served as a control group (CON). The sample sizes for the MTT and CON groups were both 25. The MTT group participated in basic Muay Thai training, while the CON group continued their normal life regime. The SF-12 quality of life scale, love of life scale and multidimensional self-control scale were administered before and after the six-week training period. Results The study concluded that the six-week Muay Thai training program had a significant effect on quality of life levels, with 13.23% (p = 0.003) and 21.93% (p < 0.001) of participants demonstrating improvements in physical and mental scores, respectively. In terms of self-control levels, the program was found to have a significant effect on initiation and inhibition scores, with increases of 23.78% (p = 0.001) and 24.69% (p < 0.001), respectively. It was concluded that had a significant effect on the sub-dimensions of the Love of Life scale with increases of Positive Attitude Toward Life (PAWL) 18.63% (p < 0.001), Happy Results of the Love of Life (HRLL) 20.11% (p < 0.001) and Meaningfulness of Life (ML) 15.62% (p < 0.001), respectively. However, no significant differences were detected in any of the scales within the control group. Conclusion Muay Thai exercises had a positive effect on quality of life, love of life and self-control levels in healthy male subjects. By providing valuable insights into how Muay Thai exercise affects quality of life, love of life, and self-control, this research can guide future intervention and program design in the context of sport psychology.
