High-Tech suits tested on cyclists – do they really work?
NCT ID NCT07503977
First seen Jun 26, 2026 · Last updated Aug 18, 2026 · Updated 3 times
Summary
This study tested whether full-body suits made with far-infrared (FIR) emitting fibers affect body temperature, heart rate, oxygen use, and power output in young competitive cyclists. Nine cyclists rode a stationary bike for 40 minutes at a steady pace, then did a 5-second sprint, wearing either the FIR suit or a placebo suit. Researchers measured skin and core temperature, heart rate, oxygen consumption, and sprint power. The goal was to see if FIR textiles could help with thermoregulation and performance.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Far-infrared emitting textile suit
- What this could lead to
- If effective, FIR clothing might help athletes manage body temperature and improve performance during exercise.
- What could go wrong
- This was a very small study (9 cyclists) looking at short-term effects. Results may not apply to other sports or real-world conditions.
