简要总结
This randomized double-blind placebo-controlled trial will investigate the effects of multi-ingredient supplementation containing taurine, caffeine, and phosphatidylserine on physical performance, cognitive function, cognitive fatigue responses, recovery, sleep quality, and autonomic nervous system activity in elite male soccer players. Participants will complete a 14-day supplementation protocol and undergo football-specific performance, reaction-time, cognitive-fatigue, recovery, and sleep-related assessments before and after the intervention. The study aims to determine whether phosphatidylserine dose influences physical, cognitive, fatigue-related, and recovery-related outcomes when combined with taurine and caffeine.
详细描述
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.
