The effect of concurrent training on ghrelin, growth and insulin hormones in obese men

 
Purpose: The aim of this study was to investigate the effect of 12-week Concurrent resistance -endurance training on the acylate Ghrelin, Growth and Insulin Hormones in Obese Men. Methods: 30 non-athlete obese men were randomly classified in two experimental and control groups. The experimental group performed the Concurrent resistance -endurance training protocol three sessions per week for 12 weeks while the control group did not do the training program during the research performance. Five ml of venous blood was taken from the participants at the beginning of the period, and at the end of week six and week 12 in order to measure Ghrelin, Growth and Insulin Hormones. Result: Findings showed that 12 weeks Concurrent resistance-endurance training led to the increase of acylate Ghrelin (p-0.0001), Growth Hormone (p=0.045) and decrease of Insulin Hormone (p=0.001) in the experimental group compared with the control group. While after week six Concurrent training this variables haven't significantly changed. Also, in the experimental group there is significant increase in the levels of acyl ghrelin and Growth hormone and significant decrease in insulin levels between post-test phase and pre- test phase. Conclusion: According to the results of this study, it was determined that regular Concurrent resistance-endurance training decrease the Weight and body fat percentage because of improving the levels of plasma Ghrelin, Growth and Insulin Hormones. Also, increased acylate Ghrelin concentrations in adaptatio with the exercise program are probably in a delay process and the duration of the training program and reduce fat and body weight change Ghrelin levels in plasma and is an effective weight
control.
