Flash of genius? light training may boost athlete reaction time
NCT ID NCT06748417
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tested whether a device called FITLIGHT, which uses flashing lights to train reaction time, could help athletes perform better in hopping and cutting movements. Eight healthy adults did a 30-minute cognitive training session with the device. The goal was to see if the training improved their reaction time and accuracy during physical tasks. However, the study was terminated early, so the findings are limited.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- FITLIGHT cognitive training device
- What this could lead to
- If it works, this could point toward a simple brain-training tool to help athletes react faster and move better during sports.
- What could go wrong
- This was a very small, early study (only 8 participants) that was terminated early, so results may not be reliable or apply to most athletes.
