Abstract

Background: The prevalence of obesity among children is alarmingly rising. Obesity in a chronical inflammatory condition accompanies with inflammatory markers such as Chemerin and CRP; therefore, the aim of this following study is to compare the affection of Endurance & High Intensity Interval Trainings on levels of Chemerin & Protein of C-reactive plasma in obese children.

Materials and Methods: This experimentation included 21 obese children (average weight 61.46±2.5 kg and BMI 7.1±4.31) aging 9-12 years old who were randomly divided into three groups of endurance, HIIT and control (n=7). The training groups performed regular exercises for 8 weeks long (3 sessions in every week). The differences between groups were evaluated using covariance analysis. (p<0.05).

Results: In both training groups, there was a more significant decrease in weight, BMI and body fat percentage than there was before workouts. In HIIT group, we witnessed a significant reduction in level of Chemerin (p=0.016) than before. CRP level was also decreased in both groups, but the changes were not significant.

Conclusion: In summary, 8 weeks of HIIT exercises compared to endurance trainings have greater effect on Chemerin and CRP levels in obese children.
