Abstract This study investigates the effectiveness of a systematically designed plyometric training program on the improvement of specific judo skill performance variables in sub-junior judokas aged between 11 and 14 years. The research aims to assess whether such training interventions can bring measurable enhancement in the execution of key judo techniques, including Ippon Seoi Nage (one-arm shoulder throw), Tomoe Nage (stomach throw), and O Soto Gari (major outer reaping throw). Through random sampling, a total of 80 judokas were chosen and split evenly into two groups: the experimental group and the control group. During the course of 12 weeks, the experimental group engaged in three one-hour plyometric training sessions per week. In contrast, the control group did not engage in any specialized training during this period. The performance of the participants was assessed using standardized Judo Fitness Tests both before and after the training intervention. Statistical analysis was conducted using Analysis of Covariance (ANCOVA) through SPSS software to determine the significance of differences between the two groups. The findings revealed statistically significant improvements in the performance of the experimental group across all three skill variables, indicating that plyometric training effectively enhances neuromuscular coordination, explosive strength, and technique execution. The study concludes that integrating plyometric drills into the training routines of young judo athletes can substantially benefit their skill development and overall performance. These results underscore the importance of age-appropriate strength and conditioning programs in competitive youth sports, particularly in disciplines that rely heavily on agility, power, and technical precision.
