Background: This study was conducted to evaluate the effect of eight weeks of High-Intensity Interval Training (HIIT) on adiponectin and AST, ALT, and ALP enzymes in obese and overweight boys.
Materials and Methods: Subjects were 22 boys aged 12-14 years old, who were randomly assigned to experimental and control groups. Experimental group: mean weight 80.08 ± 16.08, Vo2max was 36.56 ± 2.49, and BMI was 30.27 ± 5.9 and control group: mean weight 67.91 ± 7.95, and Vo2max was 44.4 ± 2.75, 38 and BMI of 60.26 ± 6.3. The experimental group performed eight weeks of HIIT training with 80% HRR intensity at 10 turns of 60 seconds, with 60 seconds rest on exercise bikes for 3 days a week. Blood samples were taken 24 and 48 hours before and after the training, ANCOVA was used for data analysis using SPSS 21 software at a significant level (p <0.05).
Results: The results showed that HIIT reduced the levels of Adiponectin and AST and ALP enzymes, but this was not significant (P≥0.05). This exercise also reduced ALT and fat percentage and increased Vo2max in subjects, with changes in all three variables significant (P≤0 / 05).
Conclusion: It seems HIIT can reduce the percentage of fat and ALT enzyme in children, which can help prevent many metabolic diseases. Also, HIIT can play a role in liver health in overweight and obese children.
