Objective: This study aimed to examine the effect of executive function load on reaction time in e-sports players and to compare their performance with an age-matched control group.Materials and Methods: This cross-sectional controlled study included 30 competitive e-sports players and 30 healthy age-matched controls. Reaction time was assessed using the BlazePod system under four conditions: simple reaction time (SRT), choice reaction time (CRT), motor dual-task reaction time (MDRT), and cognitive dual-task reaction time (CDRT). Descriptive statistics were reported as mean ± standard deviation. Group differences were analyzed using independent samples t-tests. A 2 × 4 mixed-design ANOVA was conducted with group (e-sports vs. control) as the between-subject factor and task condition as the within-subject factor. Bonferroni-adjusted post-hoc tests were applied where appropriate. Statistical significance was set at p < 0.05.Results: E-sports players demonstrated significantly shorter reaction times than controls in all conditions: SRT (291.5 ± 67.3 vs. 413.4 ± 94.1 ms, p
