Introduction:
The ability of soccer players to maintain dynamic balance is crucial for their performance in physical tasks and matches. Therefore, it is essential to examine the factors influencing the dynamic balance of these players.

Aim of the study:
This study aimed to analyze the factors affecting the Y-Balance Test scores of elite adolescent soccer players, including the dominant and non-dominant leg, leg length, and muscle strength

Material and methods:
In 2024, a study was carried out on 40 elite male adolescent soccer players who competed at an advanced level and trained at a professional center. The study involved taking measurements for the Y-Balance Test – leg length measurements, and knee flexor and extensor muscle measurements. Statistical analyses, including an independent t-test and Pearson correlation analysis, were performed to examine the relationship between the Y-Balance Test, leg length, and knee strength.

Results:
The study found that there is no significant difference in the Y-Balance Test results between the dominant and non-dominant legs of elite adolescent soccer players. Additionally, the Y-Balance Test results for dominant and non-dominant sides were not affected by leg length. However, the flexors and extensors of the knee showed a positive correlation with the Y-Balance Test.

Conclusions:
The Y-Balance Test results of elite adolescent soccer players show a connection between their dominant and non-dominant legs. Additionally, the test score seems to be influenced by knee strength to some extent. Implementing a systematic approach to managing knee strength and conducting the Y-Balance Test to enhance players performance and lower the risk of injury.
