Lactate consumption mediates repeated high-intensity interval exercise-enhanced executive function in adult males.

ABSTRACT:

Purpose

Lactate is a principal energy substrate for the brain during exercise. A single bout of high-intensity interval exercise (HIIE) can increase the blood lactate level, brain lactate uptake, and executive function (EF). However, repeated HIIE can attenuate exercise-induced increases in lactate level and EF. The lactate levels in the brain and blood are reported to be correlated with exercise-enhanced EF. However, research is yet to explain the cause-and-effect relationship between lactate and EF. This study examined whether lactate consumption improves the attenuated exerciseenhanced EF caused by repeated HIIE.

Methods

Eleven healthy men performed two sets of HIIE, and after each set, 30 min were given for rest and examination. In the 2nd set, the subjects consumed expe
