Metabolic diseases such as childhood and adolescent obesity,type 2 diabetes have become urgent public health challenges that need to be addressed.Endothelial dysfunction is considered as a precursor event of cardiovascular disease,and its prevention and treatment have become an essential focus of health management.Being obese and spend-ing less time exercising in children and adolescents almost exist simultaneously.In this context,time-saving high-intensity interval training(HIIT)intervention is essential to prevent cardiovascular and cerebrovascular diseases in children and adolescents.This article aims to comprehensively review the latest research progress on HIIT intervention in improving vascular endothelial function in obese children and adolescents.Through systematic review and comprehensive analysis,it provides theoretical and practical guidance for future research and promotes the development and implementation of effective health interventions.
