Just curious if anyone uses nutritional energy products when training or for competition? I know many of the endurance athletes use these products (Powerbar, Clifbar/Clif Shot, Gu, EAS, etc...)but in most cases, martial arts training and especially tournaments involve a lot of endurance. With the ban on performance enhancing drugs (ie. steroids), I would think that these natural products would be the next best thing. I mountain bike and I know that a Clif Shot or Shot Blok a 1/2 hour before my ride gives me that extra boost. That extra boost would also be nice for a martial arts match or for training. Any thoughts?
