Dynamic Process of Pulmonary Data Analysis: From the Athlete Mouth to the Coach Hands

The dynamic behaviour of pulmonary gas exchange variables (particularly oxygen uptake—VO2) during and after exercise has been studied throughout different exercise modes . However, from the time VO2 is measured (usually at the mouth using a breath-by-breath gas analyser—e.g. K4b2, Cosmed, Italy), until it is available for coaches (for training control and athletes evaluation), a complex system involving multi-level dynamics experimental steps must occur. Contrarily to this, the VO2 data analysis is traditionally conducted considering only the smoothing and averaging procedures of the breath-by-breath VO2 data itself. Therefore, extreme importance should be given to this dynamic process; otherwise the physiological significance of the data obtained could be misunderstood, not reflecting the truth of the physiological mechanisms underlined .
