Ice baths tested on college athletes: do they really work?
NCT ID NCT06565468
First seen Jun 24, 2026 · Last updated Aug 05, 2026 · Updated 3 times
Summary
This study looked at whether taking a 10-minute cold water bath (around 55°F) after training helps NCAA Division I athletes recover and perform better. 75 volleyball, football, and cross country athletes wore a WHOOP device to track sleep, heart rate, and other recovery signs. They also did jump and strength tests. The goal was to see if cold water immersion improves recovery and performance compared to no treatment.
