Aim: The aim of this study was to investigate the effect of six weeks of intense interval training on lipid profile, body composition indices and VO2max of overweight male smokers. Methods: 20 men with an average age of 46.41 ± 4.48 years and BMI (27.41±3.32), voluntarily participated in this study and were randomly divided into experimental (n=10) and control (n=10) groups. The experimental group performed interval exercises for 6 weeks, 3 sessions per week. The exercises consisted of 10 steps of activity at 85-95% of maximum heart rate for 90 seconds, which was accompanied by 60 seconds of active recovery. Before and 48 hours after the exercises, fasting blood was taken from the subjects. Body composition indices and VO2max were also measured. Paired t-test, independent t-test and multivariate analysis of covariance was used for intra-group and inter-groups comparison. Results A significant difference was observed between the post-test values of the training and control groups for VO2max (p=0.001) and HDL (p=0.016), but the post-test difference was not significant for TG, LDL, TC and anthropometric indices (p>0.05). The results of the paired t-test in the training group showed that HDL and VO2max levels increased significantly compared to the pre-test (P < 0.05), but the changes in other lipoproteins, body fat percentage, abdominal circumference, and waist-to-hip ratio in the training group were not significant (p>0.05). Conclusions: Six weeks of intense interval training causes a significant increase in HDL and VO2max and non-significant decrease in some body composition indicators and TG, LDL, and TC levels in overweight male smokers.
