Effects of Aerobic Training on Cardiorespiratory Factors in Men with Type 2 Diabetes

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. 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. 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). The findings of this study confirm the positive influence of aerobic training on the improvement of pulmonary functions and VO2max in patients with type 2 diabetes.
