Technically you are wrong, because all sports and phsyical activity use energy systems. Jermaine Taylor is like a sprinter, because when he does work. "It is high intensity, Anearobic" Jermaine Taylor, i don't think he has a strong. Anaerobic Lactate System, this enable's you to work at a fairly high intensity but for longer periods of time. But not at High Intensity as the Anaerobic energy system....... I don't think Jermaine Taylor has the same kind of base fitness of Joe Calzaghe or Kelly Pavlik...and i don't think he ever will. He just has not got the body type.. YEHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
