Determination of the Degree of Dynamic Stability of the Foot in Single-leg Support in Relation to the Foot Posture Index in Judokas

The goal of this observational study is to examine the relationship between foot type and dynamic stability (balance while standing on one leg) in judo athletes. Judo requires excellent balance to perform techniques effectively and avoid injuries. However, there is limited scientific knowledge about how foot posture affects balance in judokas. The main questions this study aims to answer are: * Does foot type (neutral, pronated, or supinated) affect dynamic stability in judokas? * Are there differences in balance between male and female judokas? * Does injury history affect dynamic stability? * Is there a difference in balance between the dominant and non-dominant foot? Participants in this study will: * Have their foot type assessed using the Foot Posture Index (FPI-6), a clinical tool that evaluates foot alignment * Perform the Y Balance Test, which measures how far they can reach in three directions while standing on one leg * Complete a questionnaire about their training history, injuries, and demographic information All assessments will be conducted in the participants' judo training facilities (tatami) during a single session. Researchers will compare three groups of judokas (those with neutral, pronated, and supinated feet) to see if foot type influences balance performance. This information may help coaches and healthcare professionals better assess athletes, prevent injuries, and improve sports performance in judo.
