The effects of five weeks resistance training on some vascular growth factors in sedentary men

The aim of this study was to investigate the effects of resistance training on serum Vascular Endothelial Growth Factor (VEGF), basic Fibroblast Growth Factor (BFGF) and plasma level Growth Hormone (GH) and cortisol on sedentary individual men. Therefore, we chose twenty sedentary students who divided in two groups resistance training (RT) (age 24.1 year, height 172.7 cm, weight 67.20 kg, BMI 18.93 kg/m2, %fat 17.6) and control (age 23.6 year, height 173.3 cm, weight 66.2 kg, BMI 20.66 kg/m2, %fat 20.59). After initial blood sampling, Resistance training circle group were active in the period of five weeks, the control group did not exercise in these periods. Finally, to remove temporarily the effects of exercise blood samples were taken 48 hours after the last training session. All data analysis at the significant level P≤0.05 was performed using SPSS 18 software. Independent t-test results showed that resistance training following values level of VEGF (P=0.033) Growth Hormone (P=0.001) compared to control group increased significantly whereas cortisol (0.266) and bFGF (0.086) in between resistance and control group variation non-significant. The test results show that followed by resistance training in posttest, there is a high correlation between values growth hormone and VEGF (r=0.74), the correlation is significant (P=0.014). It seems that resistance training can be increase vascular endothelial growth factor and growth hormone, thereby enhance angiogenesis.
