The aerobic exercise group and L-arginine consumption group and aerobic exercise started walking or running on the treadmill with 10 m/min and slope of 0° for 5 sessions of 15 minutes in a week. After each day, 1 m/min and 5 minutes were added to their exercise and at the end of the seventh day the speed reached to 16 m/min and the time became 45 minutes.Results: The present results showed that L-arginine supplement consumption made a significant difference between TAC-CRP indicators in supplement and placebo groups. L-arginine supplement consumption made a significant reduction in TAC antioxidant indicator and resulted in CRP increase. TAC antioxidant indicator has an increasing effect on the improvement of total antioxidant capacity of diabetic rats by doing sport exercises but the sport exercises reduce CRP level. Aerobic exercises along with L-arginine supplement consumption didn’t change TAC antioxidant indicator of mature rats a lot and are the same in both exercise and without exercise levels but had a significant difference in CRP levels between aerobic exercise-supplement and placebo groups. Exercise reduced significantly on CRP indicator of mature diabetic rats in supplement consumption situation than placebo situation. On the other hand, there was a significant difference between the mean of CRP antioxidant indicator between supplement consumption without exercise and placebo without exercise.Conclusions: L-arginine supplement resulted in the significant increase of CRP in diabetic mature rats than placebo.
