Caffeine gum gives volleyball players a jump boost, study finds
NCT ID NCT07240506
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether chewing caffeinated gum (200 mg caffeine) could help female volleyball players jump higher. Ten professional players from Turkey took part, each trying both the caffeinated gum and a placebo gum on different days. The results showed that the caffeinated gum improved one type of jump (countermovement jump) but not others. This suggests caffeine gum might give a small boost in explosive power for sports like volleyball.
