AbstractThe purpose of the present study was to investigate the effect of aerobic exercises on AKT1/ PI3K expression and Insulin sensitivity in liver Hepatocyte of obese Vistar rats. The statistical population consisted of all male Wistar rats of Baqiyatallah University of Medical Sciences in Iran. To create obesity, a high-fat diet was used for 8 weeks. 16 obese rat having similar condition were selected and randomly divided into 2 obese groups (control and aerobic exercise). To prepare a high-fat diet, 1% cholesterol powder and 1% pure corn oil were added to the standard diet of rats purchased from Parsdam Food Company. Rats in animal laboratory under controlled light conditions (12 hours light and 12 hours dark, start of lighting 6 pm and start of extinction 6 am and temperature 22 ± 3 ° C and humidity about 30 to 60%) were maintained. The use of a high-fat diet continued until the end of the study. The aerobic exercise program was performed for 6 weeks in 5 sessions per week with a gradual increase in speed (18 to 22 meters per minute) and time (10 to 55 minutes in the form of running on a treadmill). All rats 48 hours after the last training session were autopsied. The results showed that 6 weeks of aerobic training led to a significant reduction in fasting glucose in obese Wistar rats. On the other hand, it increased AKT1 / PI3K expression and insulin sensitivity in liver tissue of obese Wistar rats (P≤0.05).
