This study investigated the impact of plyometric training on discus throwing performance among middle school athletes, examining the potential of targeted training interventions to enhance athletic capabilities during critical developmental stages. A quasi-experimental design was implemented with 40 high school athletes (aged 15-18) divided into experimental and control groups. The experimental group underwent an 8-week structured plyometric training program, while the control group continued standard physical education activities. Performance metrics were assessed using calibrated measuring tools, including video analysis, vertical jump measurements, rotational power assessment, and biomechanical evaluations at baseline, mid-intervention, and post-intervention points. The experimental group demonstrated significant improvements across multiple performance metrics: 23.5% increase in throwing distance, 20.2% enhancement in throwing technique score, 17.6% improvement in vertical jump height, 15.6% increase in rotational power, and 10.6% improvement in shoulder flexibility. Statistical analysis revealed these changes were statistically significant (p < 0.05), with the control group showing minimal, non-significant changes. Structured plyometric training can effectively enhance discus throwing performance in middle school athletes, demonstrating multidimensional improvements in physical capabilities, technical skill, and neuromuscular coordination. The findings underscore the potential of targeted, scientifically designed training interventions during critical developmental.
