This study combines the results of studies on the effect of plyometric training on back and leg muscle strength in different places and times to reveal the overall effect sizes of these results. For this purpose, between 2000-2020 years of plyometric training method in Turkey, back and legs taken the subject of the effect on muscle strength parameters of the Council of Higher Education of the National Thesis Archive, Google and academic journals park websites postgraduate published in theses and research papers by the inclusion of studies appropriate studies are discussed. Studies that do not meet the specified criteria are excluded from this study. For the studies whose heterogeneity value is above normal, moderator analysis of training duration, sports branch and broadcast type variables were done. Comprehensive Meta-Analysis (CMA) program was used for experimental meta-analysis. According to the results of the meta-analysis data of this study, the effect of plyometric training on the back muscle strength was 0.404 in the fixed effects model; in the random effects model, it was found to be moderate with an effect size of 0.408. In the fixed effects model for leg muscle strength, 0.478; in the random effects model, it was determined that it has a moderate effect size with a moderate effect size with an effect size of 0.525. Considering the results of this study; for the development of back and leg muscle strength, plyometric training can be said to be moderately effective.
