Research advances on high-intensity interval training and cognitive function

High-intensity interval training (HIIT) has proven to be a time-saving and efficient exercise strategy. Compared with traditional aerobic exercise, it can provide similar or even better health benefits. In recent years, a number of studies have suggested that HIIT could be used as a potential exercise rehabilitation therapy to improve cognitive impairment caused by obesity, diabetes, stroke, dementia and other diseases. HIIT may be superior to regular aerobic exercise. This article reviews the recent research progress on HIIT with a focus on its beneficial effect on brain cognitive function and the underlying mechanisms. HIIT may become an effective exercise for the prevention and/or improvement of brain cognitive disorder.
