Summary

This trial tests whether menthol, given as a mouth rinse or as a dissolvable film, can improve short, intense exercise performance in healthy male volleyball players. Each participant tries both menthol forms and a placebo (water) on separate days, then performs a 30-second cycling sprint test. The study measures power output, breathing, and blood markers to see if menthol offers any edge.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Menthol (L-menthol) administered as a mouth rinse or as a buccal film
What this could lead to
If menthol improves short bursts of maximal effort, athletes might use it as a simple, drug-free way to enhance performance in sports requiring quick, powerful movements.
What could go wrong
This is a small, early trial in healthy male volleyball players, so results may not apply to other groups. Menthol could cause irritation or allergic reactions, and its effects on performance are still uncertain.
