The Effect of Circuit Resistance Training and Detraining on Plasma levels of Omentin-1 and Body Composition in Overweight and Obese Female Students

Omentin-1 is an adipokine that is expressed and secreted in visceral adipose tissue and increases insulin sensitivity. But its response to resistance exercises and detraining is unknown. The purpose of the present research is to measure the effect of an 8-week resistance training period and a subsequent detraining period on the amount of plasma Omentin-1 in overweight and obese girls. In this semi-experimental research, 22 overweight and obese girls were selected randomly and were divided into control (n=10) and experimental (n=12) groups. Experimental group exercised in an 8-week training plan, 4 times a week; with a severing gamut of 65 to 80 percent 1RM, and sequentially they experienced 4 weeks of detraining with an intention of studying the results. The blood sampling was performed after fasting for 12 hours in various phases in the same conditions and subsequently the amount of plasma Omentin-1 was measured. The results showed that 8 weeks of resistance training made significant changes in the variables of study and after 4 weeks of detraining the amount of measured variables were changed in to the significant basic levels (p
