The vortex throw, similar to the javelin throw, requires exceptional mastery of technique and specific motor abilities to ensure success. This study examines the anthropometric and motoric status of young female track-and-field athletes and investigates their relationship with vortex throwing performance. This research included 63 young female athletes; the results of 14 motor tests, three anthropometric measures, and training experience were compared with vortex throwing distance and vortex release velocity. Pearson’s correlation analysis revealed that the most valuable strong correlation was between the release velocity and the throwing distance (r > 0.75), indicating that they almost equally contributed to throwing performance. The most valuable moderate correlations were those between the leg tapping test, the overhead medicine ball throw, and the chest medicine ball launch and the performance of both forms of throwing. Accounting for shared variance among predictors, multivariable models explained 43% of the variance in vortex release velocity and 58% in vortex throwing distance, with the standing long jump uniquely predicting release velocity and the overhead 1-kg medicine ball throw uniquely predicting throwing distance. Finally, the motor abilities recognized in athletes in this research are valuable indicators of quality throwing performance and could play a crucial role in throwing success, which supports previous evidence on similar topics. Collectively, these results support using release velocity alongside distance to evaluate youth vortex throwers and highlight simple field tests (leg tapping, medicine ball throws, and long jumps) as practical markers for training prescription and early talent identification.
