By utilizing a digital cardiopulmonary rehabilitation clinical data research platform, The investigators aim to achieve automated, standardized, and uniform collection, analysis, and AI modeling of large-scale cardiopulmonary exercise testing (CPET) data. The ultimate goals are:\n\nTo establish reference standards for cardiopulmonary exercise capacity in the Chinese healthy population.\n\nTo develop machine learning-based predictive models for key CPET variables (e.g., peak VO₂) tailored to Chinese demographics.\n\nTo compare performance differences between domestically produced and imported CPET devices.",[28,29],"Oxygen Consumption","Cardiorespiratory Fitness",[31,32,33,34,35],"Peak Oxygen Uptake","VO2@AT","Cardiopulmonary Exercise Tolerance","Prediction Model","Healthy Population","NOT_YET_RECRUITING","2025-08-06",{"date":39,"type":40},"2025-08-11","ACTUAL",{"date":42,"type":23},"2025-09-01",{"date":44,"type":23},"2027-03-30",{"name":46,"class":47},"Affiliated Hospital of Changchun University of Chinese Medicine","OTHER",15,""]
