The Effect of High-Intensity Interval Training(HIIT) on Cardio-metabolic Indicators in School-age Children With High Cardiovascular Diseases Risk--a Randomised Intervention Trial
This study aims to evaluate the health promotion effects of high-intensity interval training (HIIT) intervention on school-age children who are at high risk for cardiovascular disease (CVD), as well as the long-term adherence and acceptability of HIIT in this population for future application.
• Aged 7-18 years at baseline.
• At least one of the following cardio-metabolic abnormalities:
‣ Prediabetes (Impaired fasting glucose: 5.6 ≤ fasting blood glucose level ≤ 6.9 mmol/L; or Impaired glucose tolerance: 7.8 ≤ blood glucose level after 2 hours postprandial ≤ 11.0 mmol/L).
⁃ Lipid abnormalities (High-density lipoprotein cholesterol ≤ 1.04 mmol/L; or Low-density lipoprotein cholesterol ≥ 3.37 mmol/L; or Triglycerides ≥ 1.70 mmol/L, or Total cholesterol ≥ 5.18 mmol/L).
⁃ Elevated blood pressure (Systolic/diastolic blood pressure consistently higher than the 90th percentile for gender, age, and height; or systolic/diastolic blood pressure ≥ 120/80 mmHg).
• Written consent from participants and their guardians.
