The first issue of the second volume of SPRINT is published

The latest issue of SPRINT – Sports Research International (Volume 2, Issue 1) has officially been released, delivering a fresh wave of peer-reviewed insights into sports science, athlete health, and performance optimization.

The issue opens with “The Role of Northern European Countries in the Emergence of New Training Methods in Distance Running: A Historical Overview” by Bence Kelemen, Ottó Benczenleitner, and László Tóth. The authors explore how countries such as Finland, Sweden, and Norway played a pivotal role in the development of endurance training during the 20th century. By tracing influential figures, institutional support, and socio-political factors, the article highlights how the Scandinavian model helped shape modern approaches to long-distance running.

The second article, “Analyzing Large-Scale Freediving Competition Data with a Special Focus on Gender Differences”, by F. Bittmann, offers a comprehensive statistical analysis of international freediving results. With a focus on performance trends and physiological limits, the study uncovers meaningful differences in outcomes between male and female athletes. It also points to the rapid evolution of the sport and how gender-specific factors may influence training and competition strategy.

Next, “Assessment of Sleep Quality in Adolescent Soccer Players Using the Pittsburgh Sleep Quality Index” by Johanna Takács, Judit Pelle, Bettina Béres, and Ákos Koller brings attention to the growing concern of sleep hygiene in elite youth sports. In a study involving players from the Puskás Akadémia, the authors conclude that sleep problems are common among adolescent soccer players, thus early identification of sleep problems among athletes can help to improve well-being and performance as well as reduce the risk of injury.

The issue concludes with a brief but thought-provoking review titled “The Effects of Dog Sport on the Psychological Conditions of Humans” by Hajnalka Eszter Selmeci and Noémi Gyömbér. This paper explores how participating in competitive dog sports impacts the mental well-being of human handlers. Based on the literature review, the authors conclude that participating in agility can have a positive influence on the handlers' mental state.
