    Objective: To explore the characteristics of cardiopulmonary exercise capacity in adults with different degrees of obesity through cardiopulmonary exercise test (CPET). Methods: From September 2019 to January 2024, the data of patients undergoing CPET in the Rehabilitation Department of the Affiliated Wuxi People’s Hospital of Nanjing Medical University were analyzed retrospectively. A total of 231 cases were included. They were categorized into five groups based on their body mass index(BMI): the control group (18.5 ≤ BMI < 24 kg/m², n=28), the overweight group (24.0 ≤ BMI < 28 kg/m², n=48), the mild obesity group (28 ≤ BMI < 35 kg/m², n=75), the moderate obesity group (35.0 ≤ BMI < 40 kg/m², n=47), and the severe obesity group (BMI ≥ 40 kg/m², n=33). Collected informations on the age, gender, height, and weight of five groups of participants. The VO2 at anaerobic threshold (VO2AT), percentage of predicted VO2AT (VO2AT% Pred), peak oxygen consumption (VO2peak), percentage of predicted VO2peak (VO2peak% Pred), peak kilogram oxygen consumption (VO2peak/kg), maximum exercise power (WRmax), breathing reserve (BR), maximum heart rate (HRmax), percentage of predicted HRmax (HRmax% Pred), maximum O2 pulse (VO2/HRmax), percentage of predicted maximum O2 pulse(VO2/HRmax%Pred), maximum relative O2 pulse( VO2/HRmax/kg) ,heart rate response(HRr), forced vital capacity (FVC), ratio of forced expiratory volume to vital capacity in 1 second (FEV1/FVC), percentage of predicted forced vital capacity (FVC% Pred), percentage of predicted forced expiratory volume ratio of 1 second (FEV1% Pred), peak expiratory flow rate (PEF), maximum exercise ventilation (VEmax ), maximum voluntary ventilation (MVV) and other indicators during the CPET were collected .Single factor analysis of variance was used to compare the mean of each index between groups. Spearman correlation analysis was used to analyze the correlation between BMI and various indicators.
