The Impact of High-Intensity Interval Training on Brain Health in Athletes A comprehensive review

Abstract

Background and goal:

HIIT It is a form of cardiovascular exercise that involves alternating between short bursts of intense anaerobic exercise and low-intensity recovery periods. HIIT workouts are designed to be short, typically lasting anywhere from 10 to 30 minutes

Method:

Google Scholar, Scopus, Pub Med, Science Direct and Springer databases were used to find articles in English from 2017 to 2024. Articles were extracted using the keywords HIIT, BDNF, brain health and acute exercise. 15 quality articles related to the effect of high-intensity interval training on the brain. The health status of the athletes was obtained and analyzed.

Findings:

Six articles investigated the impact of high-intensity interval training (HIIT) on cognitive performance and brain health, with the majority finding positive effects on various cognitive domains. Another six articles focused on the effects of HIIT on executive function, with most indicating positive effects. However, one study reported no specific effects of HIIT on brain functioning, and another suggested extreme fatigue from HIIT may negatively impact executive performance accuracy. Additionally, one study found no significant beneficial changes in decision-making enhancement from HIIT, while another reported positive effects on brain pressure flow.

Conclusion:

The results suggest that high-intensity interval training (HIIT) may have a positive effect on the brain health of athletes. While more research is needed to fully understand the mechanisms and long-term effects of HIIT on brain health in athletes
