The Effect of Eight Weeks High Intensity Aerobic Training on Leptin and Ghrelin of Male Rats

Abstract
Aim of this research was to study the probability changes of leptin and ghrelin hormones following eight weeks high intensity aerobic training in sprague dawley fat male rats. For this purpose randomly selected 46 two months age rats from animal lab. All rats made fat by stimulate the appetite with lettuce and vegetables and reached from mean weight 240�15 to 320�20 kg and after that randomly divided to two groups (control=23 and training=23). At the end for review the research variables, blood samples collected directly from the heart. Findings showed that eight weeks high intensity aerobic training made significant reduction in leptin (p=0/001) nevertheless had not significant effect on ghrelin (p=0/156). Regard to findings of present research it conclude that eight weeks high intensity aerobic training can induces reduction in leptin but has no effect on ghrelin.
