Aims: Many scientific studies have provided evidence supporting the positive impact of caffeine on physiological performance, leading to its increasing use by coaches and athletes. However, it is important to acknowledge that caffeine usage can also have adverse effects on athletes. With this in mind, the objective of this research was to explore an alternative solution - the application of caffeine mouth rinsing - and its influence on agility, jump height, service accuracy, and spike accuracy among male volleyball players.
Methods: To accomplish this, a group of 12 male volleyball players, aged between 18 and 25, was selected for the study. In the initial session, the experimental group, consisting of six individuals, applied caffeine mouth rinse (for 20 seconds before the game), while the control group, also comprised of six individuals, utilized water and flour nasal inhalation. The participants underwent Sargent tests, T-tests, long jumps, service accuracy evaluations, and spike accuracy assessments. Following a one-week interval, the next session took place, during which the control group replaced the experimental group.
Results: The findings indicated that caffeine mouth rinse exhibited a positive impact on explosive power and improved agility (p > 0.05). Furthermore, the results revealed a favorable effect of caffeine mouth rinse on both service accuracy and spike accuracy (p > 0.05).
Conclusion: Based on these outcomes, it appears that caffeine mouth rinsing holds promise in enhancing the performance of male volleyball players.
