Background: The age of onset of obesity and its consequences have decreased, this study aimed to compare the effect of 12 weeks of aerobic activity with light and heavy intensities on fat burning in obese and overweight children.
Materials and Methods: The statistical sample of this quasi-experimental study included 30 primary school male students with overweight and obesity (mean age 11±0.83 years and body mass index of 29.2±4.3 kg/m2). No diet control, they were randomly divided into three groups of light aerobic exercise (n=10), heavy aerobic exercise (n=10) and control (n=10). 24 hours after the first stage of blood sampling and fat assessment, the experimental groups performed aerobic activity (outdoor walking) with two intensities of light (40-50% HRmax) and heavy (80-70% HRmax) for 12 weeks. The control group did not perform any continuous physical activity. At the end of the 12-weeks exercise program, blood samples and fat assessment values were collected. Data were analyzed using paired t-test, one-way analysis of variance and Post hoc Tukey test using SPSS-24 software at P≤0.05.
Results: The results showed that both light and heavy aerobic exercise protocols decreased cholesterol, fat triglyceride, and serum leptin, LDL, BMI and HDL. However, heavy intensity aerobic exercise was significantly more effective on the above variables.
Conclusion: It seems intense aerobic exercise has a greater effect on fat burning in obese children.
