First seen Jul 13, 2026 · Last updated Jul 14, 2026 · Updated 1 time
Summary
This pilot study tests whether a custom-fitted mouthguard (occlusal splint) can improve swimming speed, stroke efficiency, and heart rate in master swimmers aged 20 to 40. Participants swim 50 and 100 meters with and without the mouthguard to see if it boosts performance. The goal is to explore a low-cost, non-drug way to enhance athletic output.

- What this could lead to
- If it works, this could point toward a simple, non-drug way to boost athletic performance in swimmers.
- What could go wrong
- This is a very small pilot study with only 20 participants, so results may not apply to all swimmers. The effect, if any, might be small or due to chance.
