Summary

This project intends to conduct a large-sample, prospective, multicenter clinical cohort study in healthy populations. 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:

To establish reference standards for cardiopulmonary exercise capacity in the Chinese healthy population.

To develop machine learning-based predictive models for key CPET variables (e.g., peak VO₂) tailored to Chinese demographics.

To compare performance differences between domestically produced and imported CPET devices.

Conditions

  • Oxygen Consumption
  • Cardiorespiratory Fitness

Interventions

OTHER

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.
