Article Nutritional, Sleep, Physical Activity, and Quality-of-Life Changes during Ramadan Fasting: A Prospective Comparative Study(Frontiers Media SA, 2026) Bayraktaroglu, Emre; Erdem, Nihal Zekiye; Mizrak, Elif; Oner Sayar, Canel; Karaagac, Rabia Melda; Gecgil Demir, Eftal; Tarakci Filiz, Nadide GizemBackground: Ramadan is the holiest month in the Islamic calendar. Ramadan fasting, which lasts from sunrise to sunset, significantly affects eating habits, physical activity, daytime sleepiness, and quality of life. In this study, body weight, daytime sleepiness (Epworth Sleepiness Scale), physical activity level, dietary intake, and quality of life (SF-36) were assessed in fasting and non-fasting individuals before, during, and after Ramadan. Methods: In this prospective longitudinal comparative study of 282 healthy adults, individuals were divided into fasting and non-fasting groups. Data were collected in four phases: 1 week before, in the middle, at the end, and 2 weeks after Ramadan. Results: Total energy intake, macronutrient consumption, and body weight decreased during Ramadan and increased again after Ramadan, with these changes being more pronounced in the fasting group. Daytime sleepiness increased and physical activity level decreased in fasting individuals during Ramadan, but both returned toward baseline levels after Ramadan. In terms of quality of life, significant differences between fasting and non-fasting individuals were observed, particularly in physical and emotional role functioning domains (p < 0.05). Conclusion: This study demonstrated that Ramadan fasting is associated with changes in dietary intake, daytime sleepiness, physical activity, and quality of life. Moreover, similar patterns observed in non-fasting individuals suggest that environmental and lifestyle factors during Ramadan may also play a role.Correction Cleats on, Battle Real: Sustainability and Gender Equality in Women’s Football (Vol 17, 1743515, 2026)(Frontiers Media SA, 2026) Aksakal, Nalan; Ornek, Serda; Erkan, Mert; Besiktas, Murat Yalcin; Terekli, Mustafa SerdarEditorial Editorial: Artificial Intelligence and Machine Learning in Pediatrics(Frontiers Media SA, 2026) Caswell, Noreen; Ehwerhemuepha, Louis; Kuru, Kaya; Hart, Gregory R.; Quon, JenniferArticle Determinants of Self-Efficacy in Wrestling Coaches: Psychological Resilience and Proactive Personality(Frontiers Media SA, 2026) Aksakal, Nalan; Örnek, Serda; Erkan, Mert; Terekli, Mustafa Serdar; Besiktas, Murat YalcinBackground and objective Coaching efficacy is a key psychological resource influencing coaches' professional effectiveness and leadership behaviors in sports. 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.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.
