  • Cardiorespiratory capacity (VO2Max) is assessed by performing a cardiorespiratory exercise test (CPET). Research postulates that a learning effect can compromise the accuracy of the CPET. Healthy populations produce high CPET reproducibility, whereas clinical populations are inconclusive. The purpose of this study was to examine the effect of a familiarization session on aerobic capacity in sedentary middle-aged females. This study recruited 6 female participants ages 35-65. Test protocol consisted of a familiarization session, a VO2Max pre-test, and a VO2Max post-test. VO2Max, respiratory exchange ratio (RER), and maximal heart rate (HRMax) were analyzed using a paired samples t-tests. Relative and absolute VO2Max significantly decreased by -9.68% (p=0.03) and -9.33% (p=0.03), from pre to post. No significant differences were observed for RER and HRMax (p=0.23; p=0.30). This potentially indicates the familiarization effectively mitigated a learning effect; however, due to the small sample size a larger sample is necessary to re-evaluate these preliminary findings.
