The Effect of Short-Term High-Intensity Interval Exercise on Executive Function in Adolescents

Abstract

HIIT (high-intensity interval training) is a short-term exercise program designed to improve executive function in adolescents. The executive function, as a key ability for individuals to engage in goal-directed behavior and solve complex tasks, includes aspects such as attention control, working memory, and cognitive flexibility. Because adolescents increasingly depend on executive function for academic success, social engagement, and daily life, it is imperative that effective methods be explored for enhancing these abilities. Existing research indicates that HIIT not only improves physical health, but also promotes cognitive function by improving brain blood flow and activating brain related areas. In this study, we investigated the specific effects of short-term high-intensity interval exercise on adolescent attention, working memory, and cognitive flexibility. The results showed that appropriate HIIT training can significantly improve the executive function of adolescents, especially in task switching and inhibition control, showing significant improvements. In addition, the influence of factors such as exercise intensity, exercise duration, and interval design on training effectiveness has also been validated in research. In summary, short-term high-intensity interval exercise as an effective cognitive intervention strategy can significantly promote the improvement of executive function in adolescents and has positive implications for their academic performance and overall development.
