Effects of Photobiomodulation on High-Intensity Intermittent Anaerobic Performance of Lower Limbs in Brazilian Jiu-Jitsu Athletes: A Randomized, Crossover, Double-Blind Clinical Trial.

Unlabelled: Photobiomodulation (PBM) has ergogenic effects on aerobic and anaerobic efforts and may improve sports performance. As Brazilian jiu-jitsu (BJJ) fighting requires both aerobic and anaerobic metabolism, so PBM may be effective in increasing the physical performance of BJJ athletes. Thus, this study aimed to verify the effects of PBM with different energy doses (6 or 12 J per point) on high-intensity intermittent anaerobic performance in BJJ athletes.
