brpm, breaths per minute; IE50, inspiratory to expiratory flow ratio at 50% tidal volume (or SLP equivalent); LOA, limits of agreement; POST‐CST, post exercise measurement session; REST1, resting breathing measurement session 1; REST2, resting breathing measurement session 2; RR, respiratory rate; tE, expiratory time; tI, inspiratory time; tI/tE, inspiratory/expiratory time ratio; tI/tTot, duty cycle; tTot, total breath time.
