the effect of 6 weeks of wrestling and wrestling-based circuit training on plasma ghrelin and some glucoregulatory hormones of well-trained wrestlers

it has been suggested that ghrelin may play a role in the response of growing hormone (gh) to exercises. the present study was designed to examine the effects of 6 weeks of wrestling and a wrestling–based circuit exercise (wbce) on plasma ghrelin and some glucoregulatory hormones in well-trained wrestlers. 30 well-trained male wrestlers (age 18.5±1.5 and bmi 24.8±6.81) voluntarily participated in 6 weeks of wrestling and wbce exercise. measured variables were plasma ghrelin and glucose, serum gh, cortisol and insulin. results showed that 6 weeks of training resulted in a significant decrease in gh, cortisol and serum insulin and a significant increase in plasma ghrelin. we concluded that an increase in ghrelin in response to a negative energy balance could not increase gh secretion and other possible mechanisms are involved in this process.
