Resumen
El texto original del estudio, en el idioma en que se publicó.
Esports athletes require exceptional cognitive and motor performance, particularly rapid reaction times (RTs). Although caffeine is widely recognized for its ergogenic effects, the benefits of combining caffeine with l-theanine or diaphragmatic breathing on esports performance have not been thoroughly examined. In this randomized, single-blind, three-arm crossover trial, 15 professional male esports athletes (mean age = 22.9 ± 3.8 years) each received three interventions in randomized order: (1) caffeine only, (2) caffeine + l-theanine, and (3) caffeine + diaphragmatic breathing, with a 7-day washout period between sessions. Primary outcomes included auditory and visual RTs and Aim Lab performance scores. Statistical analysis was performed using the Friedman and Wilcoxon signed-rank tests with Bonferroni correction. Both caffeine + l-theanine and caffeine + diaphragmatic breathing significantly improved auditory RT compared to caffeine alone (P = .027). AimLab scores also improved significantly in both combined intervention arms (P = .015 and P = .006, respectively). Visual RT did not differ between conditions. These findings suggest that combining caffeine with either l-theanine or diaphragmatic breathing may offer synergistic cognitive benefits for esports athletes, particularly in enhancing auditory RT and precision, supporting in-game performance beyond caffeine supplementation alone. Trial Registration: This study was registered at ClinicalTrials.gov (ID: NCT06621797).
