Brain function during central fatigue induced by intermittent high-intensity cycling

The central governor model putatively explains the mechanism of endurance exercise-induced fatigue, however high-intensity fatigue strategies have not been investigated yet. This study aimed to examine how affects neural response alterations, as measured by electroencephalographic (EEG) recordings, in intermittent cycling. Neural responses were assessed measuring alteration brainwaves based on spectral energy band estimates during an intermittent, high-intensity, 60-min exercise bout a cycle ergometer. ergometer incline was changed every 10 min pattern (10-20-5-20-5-10°). EEG used analyze altering brain function. Heart rate (HR), blood lactate (BL), and rating perceived exertion (RPE) after participants completed each change incline. results showed that HR, BL, RPE increased at 20° comparison 5° power significantly (P ˂ 0.01) alpha beta frequency ranges with inclines between 5 20°. over whole range from rest (theta + 251%, 165%, 145%). Higher, relative intensities (10 20°) function, regardless occurrence. HIIT (high-intensity interval training) led response. Further work investigating usefulness improve function is warranted.
