(There is a more recent Duke study that looked at the same thing in humans but you need a subcription to view so I will not bother to post a link.)
These studies are about creatine protecting athletes (they looked at sports like football) from concussions and the perhaps even scarier long term effects of multiple traumatic brain injuries. As somebody who has had both one very serious concussion, and I am quite sure, many other smaller concussions, this is an important subject to me.
One side effect of creatine supplementation is gaining water weight, which is undoubtedly a negative for skiers as it is important to have a somewhat wirey frame so that falls to not take as much of a toll on your body. However, I am not sure weather this water weight is permanent or only a short term effect and also it seems to be accepted that creatine does help you get stronger which would seem to help counteract the weight gain.
Now, here is my question. Do you think that the weight gain which I think is overall a definite negative for skiers overshadows the neurological benefits or do you think that creatine would be a good idea for freeskiers who are in the park a lot to take?
Obviously the answer is just to not hit your head but this does not seem realistic for me.
