This systematic review set out to compile the information that was currently available on the connections between sleep and (i) football players' athletic and match performance, (ii) their training load, and (iii) their injuries. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) criteria were followed in conducting a systematic review of the databases EBSCOhost (SPORT Discus), PubMed, Cochrane Library, and FECYT. The research study based on primary data analysis for determine the research used SPSS software and collect data from soccer players. Despite inconsistent results, some research indicated that sleep deprivation during football increased the frequency and severity of musculoskeletal injuries while also having a detrimental impact on physical and match performance. However, there were conflicting findings about the relationship between sleep and football players' training load, physical performance, and match results. Sleep variations had no effect on the physiological reactions (and their severity) during drill-based games. Overall result founded that positive and significant relationship in between sleep quality and athletic performance in elite soccer players. Although the research is conflicting, it seems to indicate that football players' performance is impacted and their risk of injury is raised when they don't get enough sleep.
