Caffeine consumption in volleyball players yields mixed results, with some studies showing improved jump height and ball velocity, while others show no performance enhancement.
Caffeine may help your jump and serve speed, but it doesn't work for everyone. If you try it, use a moderate dose (3mg/kg) before competition and test it in practice first to ensure it doesn't cause anxiety or jitters.

caffeine has exhibited the potential to enhance athletic performance... However, it is essential to acknowledge that Fernández-Campos et al. found no performance enhancement in volleyball players with caffeine consumption
Why this rating
Contradictory findings in the reviewed literature reduce certainty.
