Aim: Obesity appears to be associated with respiratory problems, and respiratory function is affected by various factors such as physical exercise. For this purpose, the aim of this study was to investigate the effect of eight weeks of non-linear resistance training and radio frequency (RF) on respiratory function and body composition in obese men. Methods: The current research is semi-experimental. The statistical population included obese men (mean age 30.12±2.62 years and weight 92.18±3.01 kg), and 60 people participated in this research. Subjects were randomly divided into four groups: non-linear resistance training, non-linear resistance training + RF, RF and control. Training and RF intervention was implemented three sessions a week for eight weeks. Respiratory function, body composition and VO2max were measured before and after training. Data was analysed using factorial variance analysis (2x2) with repeated measures and Tukey's post hoc test at a significant level of p<0.05. Results: Interactive effects of training and RF significantly decreased body weight (P=0.002, 3.08 %), BMI (P=0.011, 3.08 %), body fat percentage (P=0.0001, 10.16 %), and significantly increased VO2max (P=0.017, 4.52%), FVC (P=0.0001, 12.71%), FEV1 (P=0.0001, 14.96%) and FEF 75-25% (P=0.018, 5.86%). Training alone caused significant changes in all dependent variables (p<0.05), but RF alone did not cause significant changes (P>0.05). Conclusions: Therefore, the combined effect of non-linear resistance training and RF led to further improvement of respiratory function, body composition and aerobic capacity in obese men.
