Among these actions, thespotlight shines on the enhancement of change of direction (COD) speed. Several training methods have been employed toelevate this skill in football players, with plyometric training (PT) being one of the viable approaches. The objective of thisreview is to identify the diverse variables crucial for implementing an optimal PT regimen aimed at enhancing COD speedin football players.Design A systematic examination was conducted involving previously published original experimental studies featuringcontrol groups, the utilization of PT as a training modality, and the evaluation of one or multiple instances of COD in footballplayers.Method A systematic search was conducted on March 13, 2023, encompassing the MEDLINE, SPORTDiscus, and Webof Science databases. The quest was aimed at locating studies that incorporated control groups, adopted PT as a trainingmethodology, and measured one or multiple COD scenarios, with studies being published in either English or Spanish.Results A total of 34 studies were encompassed in this systematic review. Remarkably, with the exception of one, all thestudies exhibited enhancements in COD performance through qualitative assessments when employing PT. It appears thatPT, when used in isolation, is not outperformed by PT combined with another training method in the context of enhancingCOD speed, provided that the overall training load remains unchanged.Conclusion To improve COD speed in football players, a PT program spanning 6–9 weeks, featuring two weekly sessionswith a 48 to 72-h rest interval between sessions, is advisable. The program should include 1–6 exercises that incorporateboth unilateral and bilateral executions across various planes, performed at maximum intensity. Additionally, rest intervalsbetween sets should range from 60 to 90 s, and the number of contacts should be increased by 60–200.
