Summary

Many teen athletes show up to practice already dehydrated. Researchers at the Gatorade Sports Science Institute are testing whether giving high school athletes a set schedule for drinking water works better than teaching them about hydration. The trial enrolls 131 athletes aged 13 to 19 in indoor and outdoor sports and compares their hydration levels over time. The goal is to learn which approach helps young athletes stay properly hydrated.

What this could mean

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

Active substance
A prescribed schedule of bottled water plus hydration education, compared with hydration education alone
What this could lead to
If prescribed drinking works better than education alone, schools and teams could adopt simple water schedules to help teen athletes stay hydrated.
What could go wrong
This is a small behavioral study in one sports program, so results may not apply to other schools or climates. Hydration habits are hard to change, and better hydration may not translate into better performance.
