Freezing for fitness: can extreme cold boost Post-Workout recovery?
NCT ID NCT07617857
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether whole-body cryotherapy (extreme cold exposure) helps muscles recover after exercise-induced fatigue. Thirty healthy male university students ran until tired, then either sat in a freezing chamber or rested normally. Researchers measured leg strength, heart rate, blood pressure, and perceived fatigue to see if the cold treatment improved recovery compared to passive rest.
