Background: The purpose of this study was to compare effectiveness of short term resistance training using elastic resistance band over aerobics on obesity in multidisciplinary program and assess if eight weeks of training are decent for reduction of muscle and fat mass. Methods: Thirty healthy and untrained obese adults (07males and 23 females) were included in study and then randomly assigned into an Elastic resistance training group (n=15) and Aerobic training group (n=15). Each subject underwent testing of BMI, WC, WHR, BMR before and after the intervention. Both the group completed an 8-week exercise training period. Result: Average age, height, weight and BMI for the elastic resistance training subjects were 32.99 ± 1.59 and for aerobic training subjects 32.65 ± 1.97 respectively. There was no significant difference in age and BMI between the two groups. In our study we found that aerobic exercise and resistance training resulted in reduction in BMI, WC and BMR parameter. The results of this study clearly demonstrated that there was no significant difference between the two treatments and both the interventions found effective in treating obesity. Conclusion: In conclusion, both resistance training using elastic band (Theraband) and aerobic exercise for 8 weeks is statistically significant in reduction of obesity.
