Study On The Effectiveness Of Using The Nage-No-Kata Programme To Increase The Technicality Index In Adolescent Judo Athletes

This study examines the efficacy of a Kata-based technical training programme in improving Judo technique execution. Conducted over eight months (September 27, 2021-April 27, 2022) at the Municipal Sports Club in Bucharest, the experiment involved 16 performance-level judokas with a minimum of five years of experience. A structured Nage-No-Kata programme was implemented three times weekly, with initial and final assessments evaluating Kata performance and competition technique (Ippon scoring). Wilcoxon test results revealed significant improvements (p 0.05) in Kata execution (W = 3.5, Z = -3.20) and Ippon performance (W = 0, Z = -3.51), with effect sizes of 0.80 and 0.87, respectively, indicating a strong positive impact. The findings of this experiment on the use of the Kata tool in Judo sports training for enhancing technical proficiency show that competitive performance can be improved. However, limiting factors place this study in the position of a starting point for future research on this topic
