It is difficult to setup or "frame" given statements accurately enough to withstand "scientific" scrutiny. I take issue with the your supposition of "knowing" what amount of given energy is produced anerobically in any given athletic effort. As well, the mechanics of various muscle activity are so diverse that one cannot supppose that "no rest" is available to some tissue, and that somehow "all" cells are recruited during efforts. As I previously stated:I admit, that I cannot decribe the differing metabolic pathways activated in "real life" situations that would support my inference. Yet, I believe there are poorly understood relationships of metabolic activities and their effects on human performance. I'm not endorsing creatine supplementation for anyone, I'm acknowledging that for some reason it helps people that "theoretically should not be helped". __________________ Jim

It seems there is a great body of evidence showing that creatine has no beneficial effects for endurance or sub-maximal exercise activities. Yet, logic dictates, (at least mine) that any additional creatine stores, like glycogen, will aid in prolonging exercise activity. >Actualy, it tends to improve recovery of creatine stores between sprints rather than prolonging exercise or increasing exercise intensity in a single bout of exercise. As creatine is not used to a great extent in endurance or submaximal exercise, changing creatine levels will have very little effect on performance.

Is the statement "creatine has no beneficial effects for endurance exercise activities" a bit misleading? Agreed, that if I'm about to do a 25 mile TT, then a few spoons of creatine just before I start probably won't help. But what if my training for the TT involves high intensity intervals at or just above my lactic threshold? Surely creatine will help here, and this may then lead to improved performance in the TT?

Riding at LT and the high intensity intervals required for TT performance use aerobic metabolism and anaerobic glycolysis (lactic acid system). Therefore I'm not sure that creatine would help here. This might be different for training for madisons, points races and other similar track endurance events where training would involve short and explosive sprints. A similar thing could be applied to the 1 KM time trial where creatine is unlikely to help performance significantly in a race, but as almost all of the training is short and explosive creatine might improve quality. __________________ www.cyclingforums.com Last edited by 2LAP : 17-06.-2003 at 10:23 PM.
