Abstract

The unique physical demands of soccer necessitate optimal nutrition strategies for enhancing players' performance, recovery, and overall health. However, the effects of nutrition interventions on professional soccer players remain underexplored. This review aims to synthesize the current literature on the impact of nutrition interventions on professional soccer players' performance to inform future research and practical applications. The review will follow the PRISMA guidelines and the Cochrane Handbook of Systematic Reviews. We will employ a four-part search strategy to identify relevant studies, including electronic bibliographic databases, trial registers, the web of clinical trials, and bibliography screening. Inclusion criteria will encompass randomized clinical trials involving professional or semiprofessional soccer players utilizing a nutrition or diet intervention. Quality assessment will be conducted using the Risk of Bias 2 (RoB 2) tool. A narrative synthesis will be provided, detailing the intervention types and their effects on performance. This review will offer a comprehensive understanding of the potential benefits of nutrition interventions for soccer professionals, helping coaches, nutritionists, and players to tailor their approaches for optimal performance and recovery.
