The goal of this study is to determine the effects of high-intensity interval training and crossover point exercise training on vascular health in young overweight women.

In recent years, improving cardiovascular health through exercise has become a popular research question, however, it is not clear which intensity and modes of exercise bring more benefits. Crossover point(COP) intensity has great medical potential as a personalized exercise intensity that is based on substrate utilization mode, especially in overweight and obese people.On the other hand, several studies have demonstrated that HIIT is an effective method in improving vascular endothelial dysfunction. During our study, we evaluated the vascular health changes in young overweight women who received either COP exercise or HIIT exercise for 10 weeks.
