The Effect of Eight Weeks of HIRT Training on the Serum Levels of Chemerin, Vaspin, and Factors Affecting the Pathogenesis of Diabetes in Obese and Overweight Pre-Diabetic Men

The expression of chemerin and Vaspin bioactive molecules is done through the communication between adipose tissue and other biological systems of the body, which play a role in the pathogenesis of metabolic syndrome, obesity, and diabetes. This study aimed to investigate the effect of eight weeks of HIRT training on the serum levels of Chemerin, and Vaspin, and factors effective in the pathogenesis of diabetes in obese and overweight pre-diabetic men.

In this semi-experimental study, 30 pre-diabetic obese men (30 to 45 years old) were randomly assigned to two experimental and control groups (15 people in each group). The experimental group participated in the HIRT program with an intensity of 80-85% of 1 repetition maximum for 8 weeks and three sessions each week for 60 minutes. The serum levels of Chemerin, Vaspin, and diabetes factors were measured on two occasions pre-test and post-test.

The results of covariance analysis showed that the values of Chemerin (P=0.001), Vaspin (P=0.001), insulin (P=0.001), glucose (P=0.001), and insulin resistance (P=0.001), were significantly reduced in the experimental group compared to the control group. The intra-group results of paired t-test also showed a significant decrease in Chemerin (P=0.001, -0.90 percent), Vaspin (P=0.003, -16.6 percent), insulin (P=0.001, -17.5 percent), glucose (P=0.001, -19.1%), and insulin resistance (P=0.001, -40.8%) in response to the training protocol (P<0.05).

In general, HIRT training can have a beneficial effect on Chemerin, Vaspin, and some factors affecting diabetes and body composition in pre-diabetic obese men.
