Abstract: Keywords: Concordance Correlation Coefficient, Intraclass Correlation Coefficient, Bland-Altman, Agreement Analysis, Cardiorespiratory. Abstract: The aim of this study is to validate cardiorespiratory function measurement of a healthy population provided by a wearable textile during a progressive maximal exercise test. The following measurements were collected using embedded sensors to assess three variables: heart rate (HR), breathing rate (BR) and ventilation (Ve). These variables were recorded simultaneously by the wearable textile and using as a reference system for a comparison purpose. The validation was performed based on the two systems agreement estimation by calculating the intraclass correlation coefficient (ICC), the concordance correlation coefficient (CCC) and the Bland-Altman plot for each variable. Twenty-eight healthy volunteers participated in this study. Analysis of each participant under exercise condition by the two measurement systems revealed high CCC values (rc between 0.91 and 0.99), no deviation from the 45� line (Cb between 0.96 and 0.99) and significant ICC values (r between 0.91 and 0.99, p < 0.05) for HR and BR. The Bland Altman plot for HR and BR indicated no deviation of the mean difference from zero and a small variability with tight agreement limits. However, the analysis of the estimated ventilation Ve of each participant revealed doubtful values for the CCC (rc between 0.2 and 0.99) and ICC (r between 0.11 and 0.99). In summary, the Hexoskin presented good agreement for HR and BR. However, for ventilation, it is difficult to conclude from the results due to variability
