Adiponectin plays an important role in many metabolic and heart diseases. Regulation of liver enzymes is also essential for the health of the body's organs. Therefore, this study aimed to evaluate the effect of a HIIT training period on adiponectin levels and serum concentrations of liver enzymes in obese and overweight boys. 22 obese and overweight boys were selected and randomly divided into two groups of control and experimental. The experimental group performed eight weeks of HIIT pedaling with 80% HR reserve intensity for 3 days a week. The variables of adiponectin, aspartate aminotransferase (AST), alkaline phosphatase (ALP), alanine aminotransferase (ALT) using kits and laboratory methods as well as aerobic power, body mass index, and fat percentage of tests in the two stages before and after Exercise protocol was also measured and covariance test was used to compare the research variables and Pearson correlation coefficient was used to examine the relationship. The results were analyzed at a significant level (P<0.05) using SPSS software version 24. Performing eight weeks of HIIT exercise using a bicycle resulted in a non-significant reduction in adiponectin (P>0.05), AST(P>0.05) and ALP(P >0.05) enzymes. This exercise also significantly reduced ALT enzyme (P<0.05) and fat percentage (P<0.05) and increased aerobic capacity (P<0.05)
HIIT exercise strengthens aerobic power and reduces the percentage of fat and reduces the liver enzyme ALT in obese boys. Of course, more research is needed to clarify this issue.
