New wearable facemask could replace bulky lab gear for fitness tests
NCT ID NCT07596108
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares a new wearable facemask device (Calibre) to a standard lab system (COSMED) for measuring fitness during intense exercise. Researchers will enroll 40 healthy adults aged 18-55 to see if the Calibre device accurately tracks oxygen use and other key fitness measures. If successful, this could lead to simpler, more accessible fitness testing outside of specialized labs.
