While moderate\u2010intensity continuous training (MICT) benefits cardiovascular health in obese adolescents, the effects of high\u2010intensity interval training (HIIT) are less understood. We hypothesize that HIIT may be more effective than MICT in improving VO<jats:sub>2<\/jats:sub>peak, vascular elasticity, endothelial function, and vago\u2010sympathetic balance in obese adolescent boys. Forty four participants were randomly assigned to the HIIT (10\u00a0\u00d7\u00a01\u2010min at 85%\u201395% peak HR, intersperse with 2\u2010min active recovery at 60%\u201370% peak HR) or MICT (35\u00a0min at 65%\u201375% peak HR) for an 8\u2010week program. The primary outcome measured was the change in VO<jats:sub>2peak<\/jats:sub> with secondary outcomes including brachial\u2010ankle pulse wave velocity (baPWV), flow\u2010mediated dilation (FMD), and heart rate variability (HRV). Forty four adolescent boys with obesity (age, 14\u00a0\u00b1\u00a01\u00a0years old, body mass index, 31.6\u00a0\u00b1\u00a01.3\u00a0kg\/m<jats:sup>2<\/jats:sup>) were enrolled and 43 (97.73%) completed the 8\u2010week exercise. No significant difference of VO<jats:sub>2peak<\/jats:sub> was found between the HIIT and MICT group (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.243). There was no significant difference of baPWV between the groups (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.789). Change in FMD% was significantly higher in the HIIT group compared to the MICT group (<jats:italic>p<\/jats:italic>\u00a0&lt;\u00a00.001). The Change in HRV\u2010high frequency (HRV\u2010HF; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.009) and HRV\u2010low frequency\/high frequency (HRV\u2010LF\/HF; <jats:italic>p<\/jats:italic>\u00a0=\u00a00.035) was significantly higher in the HIIT group compared to the MICT group. Among adolescent boys with obesity, 8\u2010week HIIT and MICT had similar effects on improving VO<jats:sub>2peak<\/jats:sub>. HIIT may be superior to MICT to improve endothelial function and vago\u2010sympathetic
