  FIGURE 1. Comparison of data registered with COSMED and VITALPATCH devices during the incremental test in normoxia. Scatter points represent raw data, and the fine smoothing lines were obtained by running a LOWESS method. Data included several 4‐min bouts with 2 min of rest between each bout.

  FIGURE 2. Comparison of data registered with COSMED and VITALPATCH devices during the time‐to‐exhaustion test in hypoxia. Scatter points represent raw data, and the fine smoothing lines were obtained by running a LOWESS method. Data included the warm‐up followed by the workload.

  FIGURE 6. Comparison of heart rate (HR) and respiratory rate (RR) data from VITALPATCH (VP) and COSMED during the incremental test in normoxia. Analytical and statistical values are reported. Vertical lines denote the beginning and the end of the time window considered for the analyses. Horizontal lines in right panels denotes the maximum threshold that the VITALPATCH system applied for RR. Grey area denotes the difference area from the two filtered lines. Calculation and graphs were created with Python.

Analytical and statistical values are reported. Vertical lines denote the beginning and the end of the time window considered for the analyses. Horizontal lines in right panels denotes the maximum threshold that the VITALPATCH system applied for RR. Grey area denotes the difference area from the two filtered lines.
