  The mediating role of mental fatigue awareness in the relationship between perceived stress and psychological well-being among combat athletes

  Yilmaz, Taner; Öz, Faik; Gül, Oguzhan; Dal, Suzan; Kara, Tayfun; Akkoç, Orkun; Küçük, Hamza; Fort, Patricia Roxana; Çitozi, Robert; Kadi, Mustafa Nurullah

  Background Combat athletes face unique psychological demands, and stress may influence both their cognitive experiences and psychological well-being. This study aimed to examine the mediating role of mental fatigue awareness in the relationship between perceived stress and psychological well-being among combat athletes, thereby contributing to a clearer understanding of a potential cognitive mechanism linking stress to well-being in this population.Methods A total of 303 combat athletes voluntarily participated. Participants completed the Perceived Stress Scale, Mental Fatigue Awareness Scale, and Psychological Well-being Scale. Statistical analyses assessed the direct effects of perceived stress on psychological well-being, the effect of stress on mental fatigue awareness, and the potential mediating role of mental fatigue awareness.Results Perceived stress significantly increased mental fatigue awareness (b = 0.732, SE = 0.064, beta = 0.549, p = 0.001) and directly decreased psychological well-being (b = - 0.488, SE = 0.166, beta = - 0.191, p = 0.004). Mental fatigue awareness negatively affected psychological well-being (b = - 0.374, SE = 0.124, beta = - 0.195, p = 0.003) and partially mediated the relationship between stress and well-being (indirect effect: b = - 0.274, SE = 0.115, beta = - 0.107, p = 0.003; 95% CI = - 0.504 to - 0.049).Conclusion Perceived stress was associated with psychological well-being both directly and indirectly through increased mental fatigue awareness. These findings suggest that mental fatigue awareness may represent a relevant cognitive pathway linking stress perceptions to well-being. Accordingly, stress management and strategies aimed at regulating mental fatigue may be considered as potentially beneficial components in efforts to support psychological well-being among combat athletes.

  Canal Hypersurfaces Generated by Pseudo-Null Curves with Bishop Frame in Lorentz-Minkowski 4-Space

  Kazan, Ahmet; Kazan, Sema; Gur Mazlum, Sumeyye; Karaca, Emel; Altin, Mustafa; Grilli, Luca

  In this paper, we deal with the canal hypersurfaces that are formed as the envelope of a family of pseudo-hyperspheres or pseudo-hyperbolic hyperspheres with centers lying on a pseudo-null curve with Bishop vector fields in four-dimensional Lorentz-Minkowski space. We give main theorems which contain the parametric expressions of these canal hypersurfaces along with their Gaussian, mean, and principal curvatures and important geometric characterizations. We also provide these characterizations for tubular hypersurfaces. Finally, we construct an example to allow for better understanding and comprehension of the results.

  Inspiratory muscle training enhances jumping power and shooting performance in elite air pistol athletes

  Aydin, Ahmet Serhat; Yilmaz, Coskun; Söyler, Mehmet; Güney, Gamze; Eyüboglu, Ender; Karakulak, Izzet; Ceylan, Tulay; Altug, Tolga; Burac, Daniela Giconda; Sahinler, Yunus

  Background Inspiratory muscle training (IMT) has been shown to enhance respiratory efficiency, postural stabilization, and neuromuscular coordination in athletic populations. However, its effects in precision sports such as air pistol shooting remain insufficiently explored. This study investigated the impact of a 4-week IMT program on respiratory muscle strength, explosive lower-limb performance, reaction time, and shooting accuracy in competitive air pistol athletes. Methods Twenty trained male air pistol athletes (age 18-35 years) were randomly assigned to an IMT group (n = 10) or a control group (n = 10). The IMT group performed supervised inspiratory muscle training twice daily (30 breaths/session), six days per week, for four weeks, using a threshold-loading device set initially at 40% of maximal inspiratory pressure (MIP), with progressive overload applied weekly. Both groups maintained their regular shooting training routines. Pre- and post-intervention assessments included countermovement jump (CMJ) and squat jump (SJ) performance (OptoJump), visual and auditory reaction time (Cognitech), and shooting performance evaluated via the SCATT system. A two-way repeated-measures ANOVA (group & times; time) was used for statistical analysis. Results Significant group & times; time interactions were observed for CMJ height (p < 0.001, eta & sup2;p = 0.618), CMJ power (p = 0.007, eta & sup2;p = 0.345), SJ height (p = 0.050, eta & sup2;p = 0.184), and SJ power (p = 0.050, eta & sup2;p = 0.181), indicating meaningful improvements in explosive performance in the IMT group. Shooting accuracy demonstrated a large and statistically significant interaction effect (p < 0.001, eta & sup2;p = 0.532), with substantial improvement observed only in the IMT group. Reaction time variables showed favourable but non-significant trends (p > 0.05). Conclusion A short-term IMT intervention significantly enhanced lower-limb explosive performance and shooting accuracy in competitive air pistol athletes without altering overall training load. These findings suggest that IMT may represent an effective, low-cost adjunct strategy to improve neuromuscular stability and fine-motor precision in precision-sport athletes.

  Institutional and Financial Drivers of Renewable Energy Consumption and Carbon Emissions: Evidence from Developed Economies

  Oguz, Enes Cengiz; Gyasi, Evans Akwasi; Pala, Fahrettin; Pilatin, Abdulmuttalip; Barut, Abdulkadir

  The study sheds light on the subtle interactions among financial development, foreign direct investment (FDI), and the quality of regulatory frameworks, with particular reference to their deep influence on renewable energy use and carbon emissions across 22 developed countries from 2002-2021. The results show an interesting tendency: Financial development and FDI will reduce reliance on renewable energy, whereas a significant increase in GDP per capita will increase reliance. Secondly, carbon emissions have a negative association with the adoption of renewable energy and financial development, though both reduce environmental quality; there is a positive relation between real gross domestic product (GDP) and energy depletion in terms of these toxic emissions. The significant role of regulatory quality as a moderator in this process is particularly striking. There is a direct correlation between financial stability and more robust regulation, resulting in reduced financial liquidity available for investing in renewable projects and restricting the free flow of clean FDI. Crucially, the paper argues that when combined with strong regulation, FDI is more likely to contribute to reductions in emissions, while FYGD, nevertheless regulated at a high level of quality, should raise emissions. Winding up, the result indicates that neither financial depth nor institutional quality, in isolation, is sufficient to deliver significant environmental improvement. Thus, it is urgent to adopt sound green finance policies and to formulate focused regulatory systems that integrate financial development and foreign direct investment with a broader sustainability agenda.

  Short-Term Inspiratory Muscle Training Enhances Functional and Metabolic Health in Older Adults

  Konca, Erkan; Yilmaz, Coskun; Bayrakdaroglu, Serdar; Ceylan, Halil Ibrahim; Arslan, Ayla; Ocak, Hakan; Karakulak, Izzet; Sari, Rifat; Uzun, Recep Nur; Soylu, Hakan Huseyin

  Background: Age-related declines in respiratory muscle strength and ventilatory efficiency can impair functional capacity and metabolic health in older adults. Inspiratory muscle training (IMT) has been proposed as a practical intervention to counteract these changes, yet its systemic effects remain unclear. This study aimed to examine the effects of short-term IMT on functional capacity, diaphragm thickness, and liver tissue characteristics in healthy elderly men. Methods: Thirty community-dwelling men aged 60-80 years were randomly assigned to an IMT or control group. The IMT group performed four weeks of breathing exercises using a POWERbreathe (R) device at 40% of maximal inspiratory pressure, with a weekly 10% increase in pressure. Pre- and post-intervention assessments included the six-minute walk test (6MWT), diaphragm thickness and liver density via computed tomography, and quality of life (QoL; SF-12). Results: Four weeks of inspiratory muscle training significantly improved diaphragm thickness (11.7%), fatty liver density (FLD) (+16.7%), and six-minute walk performance (+5.3%), with large time x group effects favoring the IMT group. While the physical quality of life showed modest, comparable improvements, mental health outcomes demonstrated a moderate, time-dependent improvement without a significant group-by-time interaction. Conclusions: Short-term IMT improved diaphragmatic function and functional capacity in older men and was associated with favorable changes in a liver-related biomarker; however, given that only a single liver-related metric was assessed, these findings should not be interpreted as evidence of overall improvements in liver health.

  Effects of wrestling training on psychological well-being, anxiety, and resilience in adolescent boys

  Özkan, Ridvan; Yilmaz, Coskun; Uzun, Recep Nur; Bayrakdaroglu, Serdar; Akar, Ozge Orhan; Öz, Faik; Çiçekli, Atif; Çiçekli, Aylin; Dal, Suzan; Ursu, Vasile Emil

  Background Wrestling is a physically and mentally demanding combat sport that requires discipline, focus, and emotional control. Although its physiological effects are well documented, its psychological benefits in adolescents remain underexplored. This study aimed to examine whether a short-term, non-competitive wrestling program could enhance psychological well-being, reduce sport anxiety, and strengthen resilience in adolescent boys. Methods Thirty sedentary male adolescents (aged 12-15 years) were randomly assigned to a wrestling training group (n = 15) or a control group (n = 15). The intervention consisted of six weeks of supervised wrestling sessions performed three times per week. Psychological well-being (WHO-5), sport anxiety (SAS-2), and resilience (BPRS) were assessed before and after the intervention using the validated Turkish versions of the scales. Two-way repeated-measures ANOVA was used to analyze group & times; time interactions. Results Participants in the wrestling group demonstrated significant improvements in well-being (p < 0.001) and resilience (p < 0.001), alongside marked reductions in total sport anxiety and its subdimensions (p < 0.001), compared with the control group. All effects were large (eta p & sup2; = 0.52-0.94). Conclusion A structured six-week wrestling program produced meaningful psychological benefits in adolescent boys. Regular participation in non-competitive wrestling may serve as an effective approach to promote well-being, emotional stability, and adaptive coping skills during early adolescence, supporting the preventive and developmental role of combat sports in youth mental health.

  Impact of Phytobiotic Supplementation Administered in Drinking Water on Meat Quality in Heat-Stressed Broilers

  Kaya, Hacer; Kamiloğlu, Aybike

  This study evaluated the effects of a phytobiotic additive, hawthorn fruit extract (HFE), administered via drinking water on meat quality of broilers subjected to heat stress (HS). A total of 300 one-day-old broiler chicks were distributed into six experimental groups according to a 2×3 factorial design after a one-week acclimation period, with five replicates of 10 chicks each. Chicks had ad libitum access to feed and water for the duration of the 42-day trial and were exposed to a 24-hour lighting program. HS decreased the b* color value of breast meat while increasing L* and a* values and pH of thigh meat. Cooking loss (CL) of both breast and thigh meat was reduced, whereas water-holding capacity (WHC) remained unaffected. HS did not significantly alter thiobarbituric acid-reactive substances (TBARS), total saturated fatty acids (ΣSFA), or total unsaturated fatty acids (ΣUFA), but decreased monounsaturated fatty acids (ΣMUFA) and increased emulsion stability (ES) and polyunsaturated fatty acids (ΣPUFA). Adding HFE to the drinking water did not influence breast meat pH or color intensity, but WHC improved in breast meat with 0.2 mL/L HFE and in thigh meat at both HFE concentrations. The 0.4 mL/L HFE dose increased ΣSFA and decreased ΣUFA and ΣPUFA levels, while ΣMUFA decreased at both HFE concentrations. Overall, HFE supplementation mitigated several adverse effects of HS, notably enhancing ES and reducing redness of thigh meat. These findings suggest that HFE can be an effective phytobiotic strategy to improve meat quality in broilers under thermal stress conditions.

  Future Expectations of Occupational Health and Safety Students: An Analysis Based on Educational and Socioeconomic Variables

  Tuna, Hasan; Kaplan, Ahmet

  This study examines the future expectations of Occupational Health and Safety (OHS) students regarding socioeconomic determinants and the emerging digital competency gap. The sample comprises 359 students selected through convenience sampling using the "Future Expectation Scale." Results indicate students possess moderate future expectations (x̄=2.66); while career optimism is high (x̄=3.93), economic and social outlooks are significantly lower. Notably, students from foundation universities and industrially active regions exhibit significantly higher expectations. These disparities highlight a critical gap in accessing practical training resources. Consequently, the study concludes that traditional educational methods are insufficient to meet modern industry demands. Integrating immersive technologies, such as Virtual Reality (VR) and Augmented Reality (AR), into OHS curricula is essential to bridge the gap between theoretical knowledge and Industry 5.0 requirements, enhancing student motivation and career readiness.

  Lojıstık verımlılıkten sürdürülebılır kalkınmaya: G20 ülkelerı ıçın lpı ve sdgs endekslerının entegratıf analızı

  Macit, Nazife Sahin

  Bu çalışma, G20 ülkelerinde lojistik performans ile sürdürülebilir kalkınma arasındaki etkileşimi, 2022 yılı Lojistik Performans Endeksi (LPI) ve seçilmiş Sürdürülebilir Kalkınma Hedefleri (SKH) göstergeleri temelinde, bütüncül bir perspektifle incelemiştir. Korelasyon analizi ile LPI genel skoru ve alt boyutları ile SKH göstergeleri arasındaki ilişkinin boyutunu ve yönünü; sonrasında çok kriterli karar verme (ÇKKV) ve Borda yöntemleri ile ülkelerin bütünleşik performans sıralamasını açığa çıkarmayı hedeflemektedir. Korelasyon analizleri, özellikle gümrük işlemleri verimliliği, lojistik hizmetlerin kalitesi ve zamanında teslimat alt boyutları ile ithal oransızlaşma arasında; gümrük işlemleri verimliliği ile temel içme suyu hizmetlerine erişim arasında, zamanında teslimat ile temel sanitasyon hizmetlerine erişim gibi SKH göstergeleri arasında anlamlı pozitif ilişkiler olduğunu göstermiştir. Diğer taraftan, yetersiz beslenme oranı ile LPI ve alt göstergeleri arasında negatif fakat anlamsız bir ilişkinin olduğu, ayrıca elektriğe erişim ile LPI göstergeleri arasında da anlamlı bir korelasyon bulunmadığı tespit edilmiştir. SITDE yöntemi ile hesaplanan kriter ağırlıkları hesaba katılarak ülkelerin performanslarının değerlendirilmesinde FANMA, SWEI ve TODIFFA yönteminden faydalanılmış ve ortaya çıkan sonuçların birleşimi ise Borda yöntemi ile gerçekleştirilmiştir. Yapılan bütünleşik değerlendirme sonucunda Almanya, Fransa ve Çin’in en yüksek entegre lojistik ve sürdürülebilir kalkınma performansına sahip olduğu; Güney Afrika, Endonezya ve Meksika’nın ise en düşük performans sergilediği ortaya çıkmıştır. Sonuçlar, gelişmiş lojistik altyapının hem ekonomik rekabet gücünü hem de sürdürülebilir kalkınmaya katkıyı desteklediğini ortaya koymakta ve politika yapıcılar için lojistik ve sürdürülebilirlik stratejilerinin entegrasyonuna yönelik önemli ipuçları sunmaktadır.
