Introduction. obesity is the most dangerous risk factor for kidney disease if it is coupled with diabetes mellitus and hypertension, and it has a direct impact on chronic kidney disease progression to end-stage renal disease. The present study was to document the effect of 3 months of aerobic exercises vs. resistance exercises in obese patients with diabetes and chronic kidney disease. Methods. overall, 84 patients (36 males and 48 females) who met the inclusion criteria were randomly assigned to 2 groups. Group 1 received aerobic exercises 3 times/week for 3 months, and group 2 was treated with resistance exercises 3 times/ week for 3 months. Results. At baseline, no significant difference was found between the groups in body mass index, waist circumference, waistto-hip ratio, blood pressure, heart rate, or blood glucose. The difference in exercise performance between the 2 groups prior to treatment was not significant, but after 3 months of treatment, there was a significant increase in exercise performance and improvement in the parameters of body mass index, waist circumference, waist-to-hip ratio, blood pressure, heart rate, and blood glucose within group 1 and group 2, with no significant difference between the 2 groups. Conclusions. Aerobic exercise is effective in decreasing obesity and increasing physical performance in obese diabetic chronic kidney disease patients. Resistance exercises alone can also decrease obesity and increase physical performance. So, both types of exercises can be used in the treatment of obesity.
