Abstract Pacing has been considered an important aspect to determine performance in many different sports. In judo, athletes perform match simulations in different conditions (i.e., after technical-tactical, strength and conditioning or randori - contest simulation - training sessions). These conditions may affect the match simulation pacing - attacks per minute - especially when performed at the end of the session due to the accumulated fatigue. Thus, the present study aim to compare the pacing during judo match simulation between fatigued states and control conditions. For this purpose, judo athletes will perform three 4-min consecutive matches against the same opponents, with 15-min intervals simulating an official competition (i.e., after warm-up), as conducted in regular training sessions (i.e., in the last period of a typical judo session) and after a high-intensity interval exercise protocol (two blocks of 10 sets of 20s all out uchi-komi, with 10s interval between sets and 5-min between blocks, throwing the opponent in the last technique repetition). The matches will be conducted 3 min after each condition. The order of these conditions will be randomly determined, with 72h minimum interval and 96h maximal interval. All matches will be filmed and the variables related to Total Combat Time, Standing Combat Time, Displacement Without Contact, Gripping Time, Technique Time, Groundwork Combat Time and Pause Time will be determined. Attacks per minute will be considered the main outcome and compared between the different conditions. Additionally, blood lactate, heart rate, rating of perceived exertion and rating of perceived recovery will be measured before and after each match and before and after the previous condition (warm-up, judo session or high-intensity interval all out uchi-komi).
