Introduction : Lung is one of the affected organs by diabetes. The aim of this study was to investigate the effect of aerobic training on some cardiorespiratory factors in men with type 2 diabetes.

  Methodology : In this semi-experimental study, 20 men with type 2 diabetes, who met the inclusion criteria, were evaluated. The mean age of the subjects was 45.05±3.8 years and the mean fasting blood sugar was 140.55±29.8 mg/dL. The participants were randomly assigned into aerobic training (N=10) and control (N=10) groups. Aerobic training continued for 8 weeks (3 sessions per week). Maximal oxygen uptake (VO₂max) and pulmonary functions including forced expiratory volume in 1 second (FEV₁) and forced vital capacity (FVC) were measured before and after the intervention. To analyze the changes in the parameters, t-test was applied. P-value ≤ 0.05 was considered statistically significant.

  Results : After the intervention period, VO₂max (P=0.001), FVC (P=0.014), and FEV₁ (P= 0.037) significantly increased in the aerobic group. However, no significant difference was reported in the investigated parameters in the control group (P>0.05).
