Comparative assessments of the COSMED adaptive mixing chamber versus breath-by-breath methods for oxygen uptake measurements in recreationally active adults

Résumé fourni par la source

COSMED recently developed an adaptive mixing chamber (aMC) designed to pair the accuracy of traditional mixing chambers with improved temporal resolution. This study establishes the agreement between the aMC and breath-by-breath (BxB) systems and demonstrates that the aMC consistently enabled ventilatory threshold detection whenever BxB did. These findings indicate that the aMC retains optimal gas-exchange measurement quality while enabling reliable ventilatory threshold identification.
