Background:
The effects of caffeine mouth rinsing on cognitive performance using a field-based approach have not yet been investigated. This study aimed to examine the effects of caffeine mouth rinsing on tennis targeting performance in young male recreational tennis players.
Methods:
In total, 16 recreationally active young male tennis players (mean age: 22.03±1.74 years) were enrolled in this randomized, double-blind, placebo-controlled, crossover study. Test of groundstroke depth (TGD), test of groundstroke accuracy (TGA), test of volley depth (TVD), test of serve (TS) and tennis targeting performance (TTP), was assessed using the International Tennis Number (ITN) test. Interventions included 20 seconds of caffeine mouth rinsing (CMR: 300 mg/25 mL), placebo (PLA: 25 mL water), and a no-rinse control (CON) before each section of the ITN test. Data were analyzed using repeated measures ANOVA and Bonferroni post hoc tests, with a significance level of P≤0.05.
Results:
Repeated measures ANOVA revealed a significant time-dependent difference in total tennis targeting performance scores obtained from the ITN test (P<0.01). Bonferroni post-hoc tests revealed that CMR significantly increased TGA, TVD and TTP scores. TTP points were increased in CMR group in a comparison with the PLA (147.06±26.23 vs. 130.25±20.38, P<0.001) and CON (147.06±26.23 vs. 129.19±22.27, P<0.01). TTP test scores were similar between PLA and CON (130.25±20.38 vs. 129.19±22.27, P>0.05).
Conclusions:
Based on the total scores obtained from the ITN tests, the CMR intervention was found to improve tennis targeting performance in recreationally active tennis players.
