Abstract : The purpose of this study was to determine the effect of plyometric training on the javelin throwing ability of PASI Sleman athletes. This study is a pre-experimental study with a "One Group Pre-test Post-test Design" design. The study was conducted at Tridadi Stadium, Sleman, from February 3 to March 20, 2025. The subjects of this study were selected by purposive sampling. The sample in this study were all PASI Sleman javelin throwing athletes who had undertaken special training in preparation for POPDA and PORDA DIY 2025, aged 14 to 20 years, totaling 10 athletes consisting of 5 male athletes (aged 17–20 years) and 5 female athletes (aged 14–18 years). This research instrument used a javelin throwing ability test. Hypothesis testing in this study used parametric analysis, namely the paired sample t-test. Based on the results of the study, it shows that plyometric training has an effect on the javelin throwing ability of PASI Sleman athletes, the pretest results of the javelin throwing ability got an average of 27.443 meters and after receiving treatment for 16 meetings, the posttest results got an average of 31.559 meters. There was an increase in plyometric training on the javelin throwing ability of PASI Sleman athletes, an increase in the ability of female athletes by 4.04 meters or 9.41%, an increase in the ability of male athletes by 4.21 meters or 10.19%, and an increase in the overall javelin throwing ability by 4.116 meters or 14.99%.
