Hot water biking may boost heat tolerance and performance
NCT ID NCT05727774
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether water biking in hot water (35°C) helps athletes adapt to heat better than biking in neutral water (25°C). Twenty-four healthy recreational athletes completed 10 training sessions over two weeks. Researchers measured changes in distance traveled during a 30-minute time trial in a hot, humid room, as well as changes in VO2 max. The goal was to see if hot water training improves heat acclimation and sport performance.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Water biking in hot water (35°C) vs neutral water (25°C)
- What this could lead to
- If hot water biking proves better, it could offer a simple way for athletes to adapt to heat and boost performance.
- What could go wrong
- This is a small, early study with only 24 healthy athletes, so results may not apply to others or lead to clear benefits.
