[RC] The Importance of the Proctor Trials - Ridecamp GuestPlease Reply to: ti Tivers@xxxxxxx or ridecamp@xxxxxxxxxxxxx ========================================== The goals of the trials Bill conducted were several: First, what was the difference betwseen GL and AGL in terms of blood glucose changes during copetitive level endurance exercise? Answer--not much. Second, In multiple loop, multiple dose situations, is there a blood glucose crash danger using this protocol? Answer: This is an aspect that brought out an extended discussion between myself, Dr. Eleanor Kellon--mercifully abreviated in Bill's posts to RC. The answer to that questionwas complicated. First there was no crash, but a kind of cumulative effect. The problem, though, was that the dosage was not enough to actually provide a serious source of energy for the work being done. You'd have thout that the extra carbs would have been used up quickly and, consequently, you'd see an up and down blood glucose response. That didn't happen. It appeared, instead, that there was a lot more glucose avaiable, because of the dosing--where did it come from. the answer to that question, at least theoretically, was provided by Dr. Kellon: from stored liver glycogen. It appears that such a dosing protocol encourages the mobilization, and use, of liver glycogen during hard exercise. The third question was, how long could this beneficial situation be maintained? From the results, perhaps througout an endurance race. Finally, how did all this affect the performance and attitude and health of the horse. With each of his reports, Bill included an extensive discussion of these factors. both of the two horses responded favorably in all aspects, and the AGL produced a better reaction than did the GL with these parameters. Since those initial field trials, the first well-documented trials done in endurance horses, there have been many more, conducted by others who went out and bought glucometers and got into the science. Meanwhile, in the human literature, there is a continual flow of science suggesting that carb supplementation during strenuous exercise does indeed encourage the use of muscle glycogen and the release of stored liver glycogen in support of a glycogen-based exercise metabolism. Those are the facts of it. Use, or abuse, them as you will. ti =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- Ridecamp is a service of Endurance Net, http://www.endurance.net.
