Correlation between Insulin Resistance and Cardiopulmonary Function during Physical Exams for Male Patients

Objective: In this study, we investigated the correlation between insulin resistance (IR) and cardiopulmonary function during physical exams for male patients. Methods: We selected 124 healthy male participants in the physical examination center of our hospital. They were divided into 3 groups according to the homeostasis model assessment of insulin resistance values. The oxygen uptake, peak oxygen uptake (VO₂/kg), heart rate, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured by a cardiopulmonary exercise function tester. We analyzed the correlation between the index of IR and cardiopulmonary function. Results: There were statistically significant differences in body mass index, waist circumference, fasting insulin level, anaerobic threshold SBP, maximum VO2/kg and maximum SBP among the 3 groups (p<.05). However, no significant difference was found in SBP, DBP, total cholesterol, low-density lipoprotein cholesterol and fasting blood glucose levels (p>.05). The anaerobic threshold SBP, maximum VO2/kg and maximum SBP were all negatively correlated with the IR index. Conclusion: Our results indicate that IR is associated with cardiopulmonary function and that there are different correlations between the various cardiopulmonary function indexes and IR.
