Background: The consumption of fast absorption sources containing caffeine, such as caffeinated gum and coffee mouth rinsing, has been considered a practical nutritional strategy among athletes. Therefore, this study aimed to determine the effect of early absorption sources containing caffeine on the performance of female table tennis players. Method: 18 female table tennis players randomly participated in this randomized, double-blind, and crossover designed study. Before starting the test, the participants attended a familiarization session. In each test session, participants were randomly assigned to one of three conditions including chewing caffeinated gum (CG, n=6), coffee mouth rinsing (CMR, n=6) and placebo capsule (PLA, n=6). Each test session included measurement of functional, skill and cognitive tests. The collected data were analyzed (with SPSS Windows software) by repeated measure ANOVA analysis and Bonferroni post hoc test at P≤0.05 level. Results: The findings of the present study illustrated that CG and CMR increased significantly agility and reduced the amounts of errors in the cognitive test compared to PLA (p<0.05), While there was no significant difference between CG and CMR (p>0.05). Also, CG and CMR compared to PLA and CMR compared to CG rose significantly hand movement speed and movement speed (p<0.05), and CMR compared to PLA increased significantly handeye coordination, isometric hand strength, service accuracy and forehand drive (p<0.05). However, CG compared to PLA and CMR had no significant effect on hand-eye coordination, isometric hand strength, service accuracy and forehand drive (p>0.05). In addition, CG and CMR enhanced significantly the explosive power of the lower body compared to PLA (p<0.05), While there was no significant difference between CG and CMR (p>0.05). Also, CG and CMR compared to PLA and CG compared to CMR had no significant effect on the explosive power of the upper body, backhand, and counter skills (p>0.05). Furthermore, CG increased significantly accuracy in the service test compared to PLA (p<0.05). Conclusion: According to the results, it seems that early absorption sources of caffeine (CMR and CG) are efficient strategies for improving the specific performance of female table tennis players.
