Abstract

This study aimed to analyze performance, time structure, technical actions, and perceptual responses of Brazilian jiu-jitsu athletes during matches of varied duration. For this, 10 athletes were analyzed in matches of varied duration (2-min, 5-min, 8-min and 10-min). Physical tests (reaction time, maximal isometric handgrip strength, grip strength endurance, vertical jump and sit-and-reach) and perceptive scales (exertion and recovery) were applied before and immediately after a combat. The matches were recorded for technicaltactical
analysis and to determine their time structure. The main results showed that alterations were observed for the grip strength with kimono (p=.001), whereas a decrease was observed in the suspension time in the 8-min (p=.017) and 10-min (p=.002) combats compared to pre-match mean values. The rating of perceived exertion was influenced by time (p<.001), with higher values reported after combats of 8-min and 10-min duration compared to 2-min combat (p=.008 and p=.001; respectively). The effort:pause ratio did not differ between the times of combats (p=.472), but the pause time differed according to match duration (p=.004), with higher values observed in the 10-min combats than in the 2-min combats (p=.002). Thus, it was concluded that combats of longer duration resulted in higher perceived exertion, higher pause time and lower strength endurance.

Key words: combat sport, performance analysis, fatigue, strength endurance, isometric strength
