ABSTRACT=<p><bold>Purpose:</bold> The present study investigated the effects of high-intensity intermittent training (HIIT) on lower- and upper-body graded exercise and high-intensity intermittent exercise (HIIE, four Wingate bouts) performance, and on physiological and muscle damage markers responses in judo athletes.</p><p><bold>Methods:</bold> Thirty-five subjects were randomly allocated to a control group (<italic>n</italic> = 8) or to one of the following HIIT groups (<italic>n</italic> = 9 for each) and tested pre- and post-four weeks (2 training d·wk<sup>−1</sup>): (1) lower-body cycle-ergometer; (2) upper-body cycle-ergometer; (3) <italic>uchi-komi</italic> (judo technique entrance). All HIIT were constituted by two blocks of 10 sets of 20 s of all out effort interspersed by 10 s set intervals and 5-min between blocks.</p><p><bold>Results:</bold> For the upper-body group there was an increase in maximal aerobic power in graded upper-body exercise test (12.3%). The lower-body group increased power at onset blood lactate in graded upper-body exercise test (22.1%). The <italic>uchi-komi</italic> group increased peak power in upper- (16.7%) and lower-body (8.5%), while the lower-body group increased lower-body mean power (14.2%) during the HIIE. There was a decrease in the delta blood lactate for the <italic>uchi-komi</italic> training group and in the third and fourth bouts for the upper-body training group. Training induced testosterone-cortisol ratio increased in the lower-body HIIE for the lower-body (14.9%) and <italic>uchi-komi</italic> (61.4%) training groups.</p><p><bold>Conclusion:</bold> Thus, short-duration low-volume HIIT added to regular judo training was able to increase upper-body aerobic power, lower- and upper-body HIIE performance.</p>
