Improved COSMED snorkel validated for BxB gas analysis during swimming
The latest modified and improved "Aquatrainer" snorkel system by COSMED is an uncomplicated accessory for the K4 that allows Breath By Breath gas analysis during swimming.
A preliminary study by Professor Baldari (University of Rome "Foro Italico") aimed to validate the new snorkel system in both controlled laboratory and swimming pool conditions for breath-by-breath (BxB) gas analysis. The new design has been validated showing high correlation, linearity, and agreement between tests performed with the Aquatrainer and the standard facemask.
The conclusions show that "the new snorkel system independently by the usage of 2 and 4 valves, can be considered as a valid device for the BxB gas analysis in swimming being comparable to the standard facemask"
