The effect of nutrition and exercise training on irisin and semaphorin-3E levels in obese patients

We aimed to firstly examine the effects of nutrition and exercise training on irisin, Sema-3E, biochemical and inflammatory parameters in obese patients. This study was conducted using 37 individuals were divided into three groups according to body mass index (BMI) as non-obese, 1nd degree and 2nd degree obese individuals. Nutrition and exercise training were applied to groups for eight weeks. Insulin resistance decreased in non-obese and 1st degree obese subjects. HsCRP values decreased only in the second degree obese individuals. Adiponectin values were significantly decreased in all three groups. There was a negative correlation between serum adiponectin and plasma irisin levels both before and after treatment. Sema-3E levels increased significantly in only the first degree obese individuals, whereas plexin-D1 values did not change significantly in any group. Our findings indicate that nutrition and exercise training we apply improved both anthropometric measurements and biochemical parameters in obese and non-obese individuals.
