cardiopulmonary exercise testing (CPET)
In this study, the cardiopulmonary exercise testing (CPET) system used breath-by-breath continuous analysis for gas exchange and ventilation variables. The protocol included spirometry with an 8-breath data collection method. The cycle ergometer workload ranged from 10 to 40 W/min using a RAMP protocol. The standard CPET protocol comprised a 3-min rest, 3-min warm-up, 8 - 12 min incremental exercise phase, and 3-min each of active and passive recovery.
