Effect of endurance exercise on oxidative stress marker malondialdehyde in type 2 diabetic mice..
Professional Med J Jan ;27(07):1493-8.

Diabetes is associated with oxidative stress and has a significant role in the pathophysiology of the disease and its complications. Exercise training is a powerful therapeutic approach in diabetes and has protective effects against the progress of its complications. Objectives: The aim of this study was to investigate the effect of an endurance exercise program on the oxidative stress marker malondialdehyde (MDA) in high fat diet-low dose streptozotocin induced type 2 diabetic mouse model. Study Design: Randomized Control trial. Setting: Department of Physiology, Akhtar Saeed Medical and Dental College, Lahore. Period: August 2017 to August 2018. Material & Methods: 60 male albino mice were fed a high fat diet containing 60% kCal as fat for 4 weeks. This was followed by intra peritoneal injection of 40mg/kg body weight streptozotocin, given on three consecutive days. Mice with fasting blood glucose more than 250mg/dl after a week were considered diabetic. Half the mice underwent an exercise program which comprised of a 20 minute swimming session per day, with a 6% body weight load attached to the tail of mice, 3 days a week, for 4 weeks. The level of MDA was estimated in both groups using TBARs method. Results: Mean malondialdehyde level was significantly (p˂0.05) reduced in diabetic mice that underwent endurance exercise training. Conclusion: This study highlights the important role of endurance exercise in reducing oxidative stress in diabetes.
