New insight of high-intensity interval training on physiological adaptation with brain functions.

PURPOSE

Exercise effectively enhances physiological adaptation, performance, and health-related markers in healthy individuals and diseased populations. However, the type and amount of optimal exercise remain controversial. High-intensity interval training (HIIT) took the top spot in the American College of Sports Medicine worldwide survey on fitness trends in 2018.

METHODS

We review information on the effect of HIIT on physiological adaptation and the novel role on brain functions.

RESULTS

HIIT is a more cost-effective way to improve physiological adaptations with aerobic capacity, and it also enhances brain functions such as hippocampus-dependent learning and memory.

CONCLUSION

In this review, we provide insight on the utility of HIIT in improving performance and highlight suggestions for future research.
