Abstract
Background: Cardiopulmonary exercise tests (CPETs) are widely used non-invasive and reliable functional evaluation methods. This study investigated the correlation between cardiopulmonary endurance indices and plasma glucose levels and abdominal visceral fat in males with new-onset type 2 diabetes. Methods: A total of 136 male individuals, who had been treated in the First Hospital of Qinhuangdao City, were selected to form a new-onset type 2 diabetes group (66 cases) and a control group (70 cases); individuals were divided into three groups (Q1, Q2, and Q3) from low to high according to their anaerobic threshold (AT) oxygen uptake (VO2), AT VO2/kg (VO2 per kg of body weight), peak VO2, peak VO2/kg, AT heart rate (HR), peak HR, and HR recovery after 1 minute. A cardiopulmonary exercise test was used to determine the VO2 of each group of subjects for VO2 max and AT VO2/kg, HR, and HR recovery after 1 minute. The differences in fat areas and plasma glucose levels were compared under different cardiorespiratory endurance indicators. Results: Compared with the control group, the abdominal visceral fat (AVF) area, fasting plasma glucose (FPG), and postprandial plasma glucose (PPG) levels increased in the new-onset type 2 diabetes group. Concurrently, AT VO2, AT VO2/kg, peak VO2, peak VO2/kg, AT HR, peak HR, and 1-minute HR recovery all decreased, and the difference between the groups was statistically significant (P<0.05). The higher the AT VO2 and peak VO2 values, the lower the PPG level (P<0.05) and the smaller the area of abdominal visceral fat (P<0.05). The AT VO2/kg and peak VO2/kg values were negatively correlated with the abdominal visceral fat area, while other indicators had no obvious relationship with either plasma glucose levels or the area of fat. Conclusion: The levels of blood glucose and visceral fat are correlated with cardiopulmonary function. With the increase in blood glucose levels and visceral fat, the indices of cardiopulmonary function gradually decrease. The correlation between different cardiopulmonary function indices and blood glucose levels and visceral fat was different.
