Seems to be some "carb drink" technology.http://deadspin.com/the-sub2-project-takes-credit-for-kenenisa-bekeles-near-1788186671
Deadspin: It seems like most of the science or medicine that’s been applied to running has been in the form of illegal doping. I didn’t even realize there was untrammeled space in exercise science and medicine. Why has no one else thought to use these legal technologies?
Andrew Bosch: I don’t know why nobody has done it. Part of our project is to bring together existing science—others have applied a little of this or that, piecemeal, but not in systematic way, not all at once. We’re also working on new technologies, like the carb drink. Bringing together everything—existing strategies and the new stuff—and applying it to the very best athletes, that hasn’t been done before.
What is the relationship between Sub2 and Maurten, the Swedish manufacturer of the high carbohydrate drink Bekele used? They had already developed that technology, right?
In this instance, that’s correct. They [Maurten] approached us with what they were working on, this carb delivery system, and what they hoped it would do. It seemed like the thing we needed, so they gave us some to start working with. It’s a powder that’s mixed with water. We used different concentrations of the drink in field trials with a running group in Ethiopia, successively boosting the concentration to see how athletes were tolerating it.
By tolerating it, you mean not having digestive issues?
Yes, that they didn’t get an upset stomach or feel uncomfortably full.
