Multi-Ingredient Supplementation in Professional Football Players (TCP-Soccer)
Dose-Dependent Effects of Multi-Ingredient Supplementation on Physical Performance, Recovery, and Cognitive Function in Professional Football Players
연구 개요
상태
상세 설명
The planned study will be a randomized, double-blind, placebo-controlled trial designed as a continuation and extension of previous research on multi-ingredient supplementation in professional football players. The primary aim will be to investigate the dose-dependent effects of phosphatidylserine combined with taurine and caffeine under standardized football-specific training conditions and acute cognitive-fatigue conditions.
Approximately 80 professional male football players competing at national level will be randomly assigned to four groups: placebo, taurine + caffeine, taurine + caffeine + phosphatidylserine 300 mg, and taurine + caffeine + phosphatidylserine 600 mg. Importantly, caffeine and taurine doses will remain identical across all active supplementation groups in order to enable a more precise evaluation of the independent effects of phosphatidylserine.
Participants will complete a 14-day supplementation protocol and undergo baseline and post-intervention assessments including 30 m sprint performance, reaction time, cognitive-fatigue responses, football-specific GPS monitoring, fatigue-related performance decline, recovery-related variables, sleep monitoring, and autonomic nervous system activity assessment.
The study is expected to provide novel insights into the role of phosphatidylserine in football-specific performance, cognitive fatigue resistance, recovery, and neurophysiological responses in elite football players.
