About this study
Official title: PSYCHOLOGİCAL, HORMONAL, AND PHYSİCAL PERFORMANCE PROFİLES İN ADOLESCENT MALE FOOTBALL PLAYERS: AN EXPLORATORY CROSS-SECTİONAL STUDY
This study aimed to examine the relationships among psychological characteristics, hormonal markers, body composition, and physical performance in adolescent male football players. Twenty-one male football players participated in this cross-sectional correlational study. Assessments included anthropometric measurements, jumping, sprinting, agility, kick speed, psychological well-being in sport, and mental toughness. Blood samples were collected to measure testosterone, FT3, and FT4 levels. Data were examined using partial correlation network analysis, centrality analysis, hierarchical clustering, and principal component analysis.
Read the detailed description
This study was designed to examine conditional associations and similarity-based patterns among psychological, hormonal, and physical characteristics in adolescent male football players. It employed a cross-sectional correlational design and did not involve any training or therapeutic intervention.
Assessments were conducted during measurement sessions held on separate days. These sessions included evaluations of body composition, motor performance, and psychological characteristics. Venous blood samples were collected for hormonal analyses.
The analytical approach included network analysis to examine conditional associations among variables, centrality measures to assess their positions within the network, and hierarchical clustering to identify groups of variables with similar characteristics. Principal component analysis was used to summarize the multivariate data structure. Given the cross-sectional design, the analyses were intended to explore associations and patterns within the study sample rather than establish causal relationships.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Adolescent Male Football Players | Adolescent male football players underwent anthropometric and body composition assessments, physical performance tests, and psychological questionnaires during measurement sessions held on separate days. Venous blood samples were collected to measure testosterone, free triiodothyronine (FT3), and free thyroxine (FT4) levels. No training or therapeutic intervention was administered. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Hormonal Markers, Psychological Scores, Physical Performance, and Body Composition
Serum total testosterone, free triiodothyronine (FT3), and free thyroxine (FT4) were measured by immunoassay in a 5 mL venous blood sample collected after at least 12 hours of fasting. Psychological well-being was assessed using a 23-item scale (23-115 points), and mental toughness using an eight-item index (mean score: 1-7); higher scores indicate better well-being or toughness. Countermovement jump height was measured using a jump mat, standing long jump distance using a tape, 10 and 20 m sprint and T-test times using electronic timing, and kick speed using radar. The best of two trials was retained; higher jump and kick speed values and shorter times indicate better performance. Body weight, BMI, body fat percentage, and skeletal muscle percentage were assessed using bioelectrical impedance, and height using a stadiometer.
Measured: Assessed once per participant across four assessment sessions spaced 48 hours apart, over approximately 6 days from the first to the final session.
