Background and Objective: Adipokines are adipocytokines that are released from adipose tissue and play a role in increasing or decreasing insulin resistance. The aim of the present study was to survey the effect of high volume high intensity training on plasma visfatin and vaspin, insulin resistance, lipid profile and body composition of overweight men.
Materials and Methods: Twenty overweight men were randomly divided into the control group (n=10) and training group (n=10). The training group performed high volume HIT training for 8 weeks (3 times per week). Before the training period, subject’s body composition evaluated by body composition analyzer, BoCA X1 model. Fasting blood samples was also obtained before training protocol and 48 hours after last training session for evaluating lipid profile and plasma glucose, insulin, visfatin and vaspin. ELISA method was used according to instructions of kit manufacturer. Data were analyzed by covariance analysis using SPSS 20.
Results: High volume HIT decreased body fat present (p= 0.042), BMI (0.05), WHR (p= 0.007), LDL (p= 0.02), cholesterol (p= 0.00), insulin resistance (p= 0.013), visfatin (p= 0.001) and increased vaspin (p=0.002) and HDL (p=0.001) in overweigh men.
Conclusion: The results of the present study suggested that high volume HIT improves body composition in overweight men. The decreased fat present was consistent with decease of insulin resistant, serum visfatin and increase of serum vaspin. Therefore, using high volume HIT for decreasing insulin resistant by improvement in body composition, decrease of visfatin and increase of vaspin in overweight men is useful.
