Background and Study Aim. The Special Judo Fitness Test (SJFT), originally developed to assess agility, anaerobic capacity, and multidirectional movement ability in judo athletes, structurally reflects similar physical and technical demands in wrestling; therefore, this study aimed to determine whether the SJFT performance index could validly predict wrestling-specific competitive performance.
Material and Methods. Fifty male wrestlers aged 13-15 years with at least three years of competitive experience (25 medalists and 25 non-medalists) voluntarily participated. The SJFT performance index was used as the independent variable, while competitive success (1= medalist, 2 = non-medalist) served as the grouping variable; discriminant function analysis with equal priors was then applied.
Results. Box’s M test confirmed the homogeneity of covariance matrices (F = 0.081, p = 0.776). The analysis produced a single significant canonical function explaining 100% of the variance (Wilks’ λ = 0.840; χ²(1) = 8.285; p = 0.004), with a canonical correlation of r = 0.400 indicating that 16% of the variance was explained by the performance index; group centroids (–0.428 for medalists and 0.428 for non-medalists) indicated clear separation, and the model achieved 70% classification accuracy, correctly identifying 72% of medalists and 68% of non-medalists.
Conclusions. The findings suggest that although originally designed for judo athletes, the SJFT can serve as a valid and practical predictor of competitive success in wrestlers. Future research incorporating additional variables may further enhance its discriminative power.
