Nine men elite Brazilian medium heavy weight athletes performed a 10-minute SBJJC and JJAPT that required performance of a common BJJ technique for five consecutive bouts of 1-minute with 45-s rest between bouts. [La] was measured by a lactate analyzer, HR by heart rate monitor, RPE using Borg's scale, and the number of butterfly lifts (NBL) was recorded. During JJAPT, NBL decreased in the fourth and fifth bouts (p < 0.05) with increases in [La], HR and RPE (p < 0.05), indicating that the JJAPT measured anaerobic performance. [La] during SBJJC was not different than [La] at the 3rd and 4th bouts, but was significantly different than the 5th bout (p < 0.05). [La] showed strong correlation between SBJJC and JJAPT for the 3rd (r = 0.80, p < 0.05) 4th (r = 0.83, p < 0.05) and 5th (r = 0.82, p < 0.05) bouts, but not between HR and RPE. The JJAPT with four bouts presented the best combination of stimulus and highest correlation with SBJJC, supporting its use to assess anaerobic performance of BJJ athletes. These data will aid coaches and athletes to better understand the demands of their sport, and may help to monitor adaptation in sport-specific performance across periodized training plans.
