Brain Type, Playing Position, and Mental Toughness in Amateur Soccer Players

This observational study aims to investigate the association between brain type, determined by the second-to-fourth digit (2D:4D) ratio, playing position, and mental toughness among amateur soccer players. A total of 270 licensed amateur soccer players participated in the study. Mental toughness was assessed using the Sports Mental Toughness Questionnaire (SMTQ), while brain type was determined by measuring the 2D:4D digit ratio. The study examines whether mental toughness differs according to brain type and playing position, providing insight into the neuropsychological characteristics of soccer players and their potential relationship with psychological performance.

The Relationship Between Training Dynamics and General Health Status in Veteran Football Players

The goal of this observational study is to learn how training habits and general health status are related to injury risk in veteran football players (men over 35 years old who play recreational football). The main questions it aims to answer are: Do specific training patterns (such as frequency, intensity, and duration) increase or lower the risk of injury? How does general health status (including factors like sleep, nutrition, and existing health conditions) affect injury risk? Participants will: Complete questionnaires about their training habits, lifestyle, and general health Report any injuries they experience during the football season Attend periodic health assessments
