OBJECTIVE

To investigate the effects of high-intensity interval training on lipid metabolism and inflammatory factors in overweight children, and provide clinical guidance and recommendations for children's weight management.

METHODS

A retrospective study was conducted to analyze 60 overweight children, who were randomly divided into an experimental group (high-intensity interval training) and a control group (health education as intervention). Baseline data, physical indicators, and biochemical indicators were analyzed.

RESULTS

The body mass Index (BMI) of the experimental group decreased significantly more, with BMI of male and female participants showing change rates of 0.43% and 0.85%, respectively. After intervention, there were significant differences in triglycerides, total cholesterol, and lipoprotein levels between the two groups (<0.05). After intervention, the serum tumor necrosis factor alpha levels of the experimental group showed significant differences (<0.01), with an average value decreasing from 83.24 ng/L to 64.37 ng/L, and their C-reactive protein values also showed good intergroup and intragroup statistical differences (<0.05).

CONCLUSION

High-intensity interval training can effectively improve the physical fitness of overweight children, regulate their inflammatory factors, and help with weight loss.
