May be especially beneficial to athletes involved in high-intensity activities particularly where interval training and strength training are involved i.e. anaerobic activities
For this reason alone I'm surprised more martial artists aren't taking it. I think because most of the early research involved maximal strength output (re: lifting weights), people still think of it as a "bodybuilding" supplemnt, versus an "athletic" supplement.
