Aim. The objec­tive of ­this ­study was to ver­i­fy the ­effects of ­active (AR) and pas­sive recov­ery (PR) ­after a ­judo ­match on ­blood lac­tate remov­al and on per­for­mance in an anaer­o­bic inter­mit­tent ­task (4 ­bouts of ­upper ­body Wingate ­tests ­with 3-min inter­val ­between ­bouts; 4WT).
Methods. The sam­ple was con­sti­tut­ed by 17 ­male ­judo ­players of dif­fer­ent com­pet­i­tive lev­els: A) National (Brazil) and International medal­lists (n. 5). B) State (São Paulo) medal­lists (n. 7). C) City (São Paulo) medal­lists (n. 5). The sub­jects ­were sub­mit­ted to: 1) a tread­mill ­test for deter­mi­na­tion of V.O2­peak and veloc­ity at anaer­o­bic thresh­old (VAT); 2) ­body com­po­si­tion; 3) a 5-min ­judo com­bat, 15-min of AR or PR fol­lowed by 4WT.
Results. The ­groups did not dif­fer ­with ­respect to: ­body ­weight, V.O2­peak, VAT, ­body fat per­cent­age, ­blood lac­tate ­after com­bats. No dif­fer­ence was ­observed in per­for­mance ­between AR and PR, ­despite a low­er ­blood lac­tate ­after com­bat (10 and 15 min) dur­ing AR com­pared to PR. Groups A and B per­formed bet­ter in the ­high-inten­sity inter­mit­tent exer­cise com­pared to ath­letes ­with low­er com­pet­i­tive lev­el (C).
Conclusion. The abil­ity to main­tain pow­er out­put dur­ing inter­mit­tent anaer­o­bic exer­cis­es can dis­crim­i­nate prop­er­ly ­judo ­players of dif­fer­ent lev­els. Lactate remov­al was ­improved ­with AR ­when com­pared to PR but AR did not ­improve per­for­mance in a sub­se­quent inter­mit­tent anaer­o­bic exer­cise.
