Key result
12-week HIIT improves salusin, NO, and BMI in obese children versus aerobic training and control.
Why the study?
Obesity is an independent risk factor for atherosclerosis, prompting investigation into the effects of HIIT versus continuous aerobic training on atherosclerotic biomarkers in children.
Does 12-week HIIT or continuous aerobic training improve pre-atherosclerotic and anti-atherosclerotic biomarker levels in obese and overweight children?
RCT (n=45)
Randomly assigned
No
Does 12-week HIIT or continuous aerobic training improve pre-atherosclerotic and anti-atherosclerotic biomarker levels in obese and overweight children?
A 12-week HIIT program provides greater improvements in cardiometabolic and atherosclerotic biomarkers than continuous aerobic training in obese and overweight children.
Supports preferring HIIT over aerobic training to improve biomarkers in obese children; extends limited pediatric RCT evidence on exercise intensity.
Background: Obesity is an independent risk factor for the development of atherosclerosis and arterial malformations. Objectives: The purpose of this study was to investigate the effect of 12-week high-intensity interval training (HIIT) vs. continuous Aerobic training on pre-atherosclerotic and anti-atherosclerotic biomarkers levels in obese and overweight children. Methods: This study was approved by the Research Ethics Committee of Kermanshah University of Medical Sciences. Forty-five obese and overweight children (age: 11.06 0.98 years, BMI: 25.12 1.28 kg/m 2 ) were randomly assigned to a HIIT group (n = 15, 3 sessions per week, 100% -110% MAS intensity), aerobic group (n = 15, 3 sessions per week, 40% -70% HRR intensity) and control group (no exercise, n = 15), which participated in the study for 12 weeks. Physical, physiological and blood variables measured at the beginning and end of the 12-week study. Descriptive statistics used to describe the variables and inferential statistics were used to data analysis Results: The results showed a significant increase in serum levels of salusin- and NO in both training groups, but the contribution of HIIT was more significant in the intergroup review. Also, the levels of salusin-, body weight, BMI, %BF, WHR and TG/HDL ratio were significantly decreased in both training groups, which were more significant in the HIIT group. Conclusions: According to our findings, the use of HIIT seems to be considered as an important factor in preventing chronic diseases of passive lifestyle for obese and overweight children. Therefore, to improve cardiometabolic health in obese and overweight children, we recommend regular physical activity with greater emphasis on HIIT.

Paahoo et al. (2020) conducted an RCT in Obese and overweight children (n=45). High-intensity interval training (HIIT) vs. Continuous aerobic training and no exercise control was evaluated on Pre-atherosclerotic and anti-atherosclerotic biomarkers levels (salusin, NO, body weight, BMI, %BF, WHR, and TG/HDL ratio). A 12-week high-intensity interval training program significantly improved serum levels of salusin and NO, and decreased body weight and BMI in obese children compared to aerobic training and control.
