Method choice warrants caution in Q/VO2 interpretation during exercise; leaves open standardization of cardiac output techniques.
Does the method used to measure cardiac output during exercise affect the calculated Q/VO2 relationship in male subjects?
Determination of cardiac output during exercise depends significantly on the applied method, with slopes of the Q/VO2 relationship differing by up to 50% between techniques.
Siebenmann et al. (2014) studied this question.
