Abstract

Previous studied have been shown higher serum ghrelin in diabetic patients than those without diabetic symptoms. In this study, we investigated serum ghrelin in response to an acute exercise test in adult men with type 2 diabetes. For this purpose, serum ghrelin, glucose and beta cell function were measured before and after a cycling test in nine males with type 2 diabetic (age 43 ± 7 yrs, body weight 91 ± 7 Kg). Student’s t-tests for paired samples were performed to determine significance of changes in variables by exercise test in studied patient. A p-value < 0.05 was considered to be statistically significant. Cycling exercise test resulted in significant decrease in ghrelin (0.012). Beta cell function was also increased after exercise test (0.038). Glucose concentration was decreased by exercise test in studied patients (0.008). Finally, it should be acknowledged that acute exercise with moderate intensity even for short-time can be decrease serum Ghrelin that is associated with an improvement in glucose in beta cell function in diabetic patients.
