Background: It is well-established that, for adolescents to adopt sustainable healthy lifestyle behaviors, not only access to information but also the skills required to translate that information into action are critical. In this field, research that examines the relationship between e-health literacy and sustainable healthy lifestyle behaviors within the context of physical literacy is notably scarce. In this context, the aim of this study is to examine the effect of e-health literacy on a sustainable healthy lifestyle and to evaluate the mediating role of physical literacy in this relationship. Methods: A total of 835 adolescents from high schools across Türkiye voluntarily participated in this study. During the data collection process, the e-Health Literacy Scale, the Perceived Physical Literacy Scale, and the Healthy and Sustainable Lifestyle Scale were utilized. Data were analyzed using the JASP (version 0.18.3.0) software. Correlation analysis and structural equation modeling were conducted, and the bootstrap method (n = 5000) was employed for mediation analysis. Results: The effect of e-health literacy on a sustainable healthy lifestyle was found to be positive and statistically significant (β = 0.452, p < 0.001). Similarly, e-health literacy significantly predicted physical literacy (β = 0.755, p < 0.001), and physical literacy significantly predicted a sustainable healthy lifestyle (β = 0.310, p < 0.001). The mediating effect was also statistically significant (β = 0.234, p < 0.001). The model explained 32% of the variance in healthy lifestyle behaviors. Conclusions: The findings indicate that evaluating e-health literacy and physical literacy together provides a holistic approach to fostering sustainable healthy lifestyle habits among adolescents. It is recommended that intervention programs be structured to encompass both areas of competence.

The escalating concern regarding internet and digital game addiction among pre-adolescent children and its potential link to psychological issues prompted this study, aimed at evaluating digital game addiction levels and attitudes towards gaming in secondary school students. Conducted with a sample of 897 students from Ankara, Türkiye, the study employed a survey method, utilizing the "Attitude Scale towards Digital Game Addiction and Digital Games". Results indicated significant gender differences in addiction levels and attitudes, with boys showing higher scores. Age also played a role, with seventh graders exhibiting the lowest and eighth graders the highest addiction behaviors. Notably, those engaged in martial arts games and using consoles for gaming reported the highest addiction and positive attitude scores. The study underscores the prevalent issue of digital game addiction among youths, suggesting a strong correlation with physical inactivity. It concludes that promoting physical activity is essential not only for physical health but also as a preventative measure against the development of psychological issues stemming from digital game addiction. Keywords: digital game addiction, adolescent psychology, physical inactivity, secondary school students, attitudes towards gaming, gender differences in gaming, gaming platforms, behavioral impacts of gaming

Sports injuries, which are defined as sports-specific injuries, have been significantly affected by the increasing popularity of sports and the continuous development of athletes. The knee joint, which is the largest and most complex joint of the human body, is one of the seven major joints of the body, where soft tissues such as the meniscus, femoral cartilage, tibial plateau cartilage, ligament and tendons are located. This complex joint is very susceptible to injuries due to its ability to withstand anatomical and physiological loads. Anterior Cruciate Ligament, an important component of the knee joint, has a key role in stabilizing the knee joint and in large mechanical loads. However, in some cases, sudden movements, strains, and rotations can cause serious damage to the Anterior Cruciate Ligament. The aim of this study is to examine the factors that cause Anterior Cruciate Ligament Injuries in detail from many perspectives. In the study, data related to Anterior Cruciate Ligament and Anterior Cruciate Ligament Injuries were determined by scanning the NCBI database. The data obtained as a result of the screening were included in the scope of the study. When the factors that may cause Anterior Cruciate Ligament Injuries are carefully evaluated, it has been determined that biomechanical and genetic factors are important risk factors in these injuries. To the best of our knowledge, the location of the Anterior Cruciate Ligament in the knee joint and the loads to which it is exposed are important biomechanical causes of injury to this region. In addition, some genes can seriously change, due to the proteins they decode, the structural integrity of soft tissues. Considering that sports have a complex structure, other factors that may cause Anterior Cruciate Ligament Injury should also be investigated meticulously.

Spor yaralanmaları, yalnızca fiziksel bir travma değil; aynı zamanda sporcunun psikolojik, sosyal ve kimliksel bütünlüğünü tehdit eden çok boyutlu bir olgudur. Bu çalışmada, spor yaralanmalarının psikolojik ve psikososyal boyutları biyopsikososyal model çerçevesinde ele alınmıştır. Literatür bulguları, yaralanma sürecinde ortaya çıkan öfke, inkâr, depresyon, motivasyon kaybı ve yeniden sakatlanma korkusu gibi psikolojik tepkilerin rehabilitasyonun başarısı üzerinde belirleyici rol oynadığını göstermektedir. Ayrıca, stres, dikkat dağınıklığı ve motivasyonel dengesizlik gibi psikolojik etkenlerin yaralanma riskini artırdığı vurgulanmıştır. Spora dönüş sürecinde ise fiziksel iyileşme kadar psikolojik hazır bulunuşluk da önem taşımakta; özgüven, korku ve kimlik yeniden inşası süreçleri bu geçişin niteliğini belirlemektedir. Rehabilitasyon sürecinde bilişsel davranışçı müdahaleler, imgeleme teknikleri, gevşeme yöntemleri ve motivasyonel görüşmeler gibi psikolojik destek yaklaşımlarının etkinliği kanıtlanmıştır. Ayrıca sosyal destek, sporcuların sürece uyum sağlamasında güçlü bir koruyucu faktör olarak öne çıkmaktadır. Antrenör, aile ve takım arkadaşlarının destekleyici tutumları sporcunun moral ve motivasyonunu güçlendirirken, dışlayıcı yaklaşımlar iyileşmeyi olumsuz etkileyebilmektedir. Sonuç olarak, spor yaralanmalarına yönelik bütüncül bir yaklaşımın benimsenmesi, yalnızca fiziksel iyileşmeyi değil, psikolojik dayanıklılığı ve sosyal aidiyeti de güçlendirmektedir.

Spor yaralanmaları hem profesyonel hem de amatör sporcularda performans kaybına, uzun süreli rehabilitasyon süreçlerine ve spordan uzak kalmaya yol açan önemli bir sorundur. Son yıllarda geliştirilen önleyici antrenman yaklaşımları, yaralanma riskini azaltmada etkili sonuçlar ortaya koymuştur. Bu çalışma, literatürde yer alan güncel sistematik derlemeler ve meta-analizler doğrultusunda spor yaralanmalarında etkili önleyici antrenman yöntemlerini değerlendirmektedir. Bulgular, kuvvet antrenmanlarının akut ve aşırı kullanım yaralanmalarını %66’ya kadar azalttığını, nöromüsküler antrenmanların alt ekstremite yaralanmalarında %27’ye varan azalma sağladığını göstermektedir (Lauersen vd., 2018; Hübscher vd., 2010). Ayrıca, kuvvet, denge, çeviklik, esneklik ve pliometrik egzersizleri içeren çok bileşenli programların en yüksek koruyucu etkiye sahip olduğu vurgulanmaktadır (Padua vd., 2018; Leppänen vd., 2014). Programların haftada 1–2 kez, 20–30 dakika süreyle ve en az 6 ay uygulanması önerilmektedir. Bunun yanında, kişiselleştirilmiş antrenman protokolleri ve koruyucu ekipman kullanımı da yaralanma oranlarını azaltmada önemli destek sağlamaktadır. Sonuç olarak, düzenli, çok bileşenli ve bireye özgü planlanan antrenman programlarının, yaralanma riskinin azaltılmasında bilimsel olarak en etkili stratejiler olduğu söylenebilir. Gelecekte yapay zekâ ve biyomekanik tabanlı analizlerin önleyici antrenman planlamasında önemli rol oynaması beklenmektedir.

This study examined the distinct and combined effects of mental and physical fatigue on prospective time perception in basketball players. Thirty-four male basketball players (22.48 ± 1.69 years) completed a repeated-measures protocol involving three conditions: mental fatigue induced by a Stroop task, physical fatigue induced by plyometric exercise, and combined mental–physical fatigue. Prospective time perception was assessed using a time reproduction task before and after each condition, with sessions separated by at least 72 h under standardized laboratory conditions. Repeated-measures ANOVA revealed significant main effects of fatigue and measurement time on signed time-estimation error (p < .001), as well as a significant fatigue × time × duration interaction (p < .001). Additional analyses showed that fatigue-related changes in absolute time-estimation error also varied according to fatigue condition, measurement time, and target duration, whereas trial-to-trial variability remained unchanged across fatigue conditions. Mental fatigue produced systematic underestimation of temporal intervals, whereas physical fatigue significantly increased signed time-estimation error only for the longest interval (24 s). In contrast, the combined fatigue condition did not exhibit a consistent directional pattern across target durations. These findings suggest that mental fatigue and physical fatigue exert distinct effects on prospective time perception, whereas the combined condition was characterized by a less uniform pattern of temporal estimation that did not yield a consistent directional shift or increased trial-to-trial variability. Accordingly, the findings from the combined condition should be interpreted cautiously, particularly in light of the fixed-order design and the absence of a distinct, statistically robust temporal profile beyond the isolated fatigue conditions.
