Validation of a Snorkel Prototype for Measuring Gas Exchange Parameters during Swimming
The study, by Prof Baldari of the University "Foro Italico" of Rome together with the University of Porto, aimed at validating the snorkel device connected to K4b2, given that previous validation studies (Keskinen 2003, Gayda 2010) reported some low systematic differences versus the use of K4b2 with the standard facemask (Mask).
The study, which involved nine subjects performing trails on a 25m swimming pool and on bike ergometer at 3 constant loads, validated the reliability of the snorkel device and rejected the systematic difference hypothesis.
To have reliable data the study confirms that "temperature measure at the turbine is needed since, as erroneously believed by others, the turbine do not have any temperature sensors so that the manufacturer recommends adjusting it to the ambient value when a snorkel is used".
The study conclusions "the new AquaTrainer prototype system is suitable for collecting respiratory gasses in swimming, and constitute an improvement regarding previous available systems".
