Summary of standardized mean difference and 95% confidence intervals reported in meta-analyses comparing the baseline to post-plyometric training changes in sprint time. Author name and year are followed by the quality of the studies score ranked by AMSTAR 2. Positive values represent improved performance effects. Each colored area represents a different magnitude of effect: gray = trivial, blue = small, yellow = moderate, and green = large effects. De Villareal et al. [42] 95% confidence interval is not clearly described in their manuscript; therefore, we reported standardized mean difference only. Taylor et al. [43] reported results from 30-, 20-, and 10-m sprints, presented in the respective order. Ramirez-Campillo et al. [53] reported results from > 10- and < 10-m sprints, presented in the respective order
