Summary

This study tests whether a new portable device called ZoneX can accurately measure breathing and carbon dioxide output during exercise, compared to a standard lab system. Twenty healthy adults will use both devices while exercising. The goal is to see if the portable device is reliable enough for wider use in sports and medicine.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
ZoneX device
What this could lead to
If validated, this portable system could make gas exchange measurements easier and more accessible for sports performance and clinical use.
What could go wrong
This is a small validation study in healthy volunteers, so results may not apply to people with medical conditions. The device may not match the reference system's accuracy.
