Subject: Re: Creatine
I used to know, and will look it up in my old notebooks later, but I seem=
 to remember that Creatine has something to do with the creation of lacti=
c acid, which would make sense since it allows increased anaerobic exerci=
se (which creates lactic acid).  It may be that when you have extra creat=
ine in your system you can do more anaerobic activity, resulting in more =
lactic acid buildup, resulting in more cramps.  Of course, I can't rememb=
er what happens after creatine"runs out" if you're not taking supplements=
=2E  Obviously you don't stop working, so why you would get less lactic a=
cid then I don't know...I'll have to go dig out my old notes (cellular ph=
ysiology)...

Hope this was some help, maybe someone with a clearer picture than I have=
 at this time will pitch in.

  I found this out the hard way during last year's biking season when I w=
ould experience sudden and extreme cramping at about mile 60 or so of 100=
+ mile rides.  The usual culprit is insufficient hydration but I knew tha=
t wasn't the case here since I am always careful to hydrate properly.  Th=
is happened about three rides in a row, all at about the same mileage, be=
fore I finally made the connection and once I went off creatine the cramp=
s never happened again.  So, now I do not use creatine during the summer =
biking season.  There is no question that it is effective for anaerobic a=
ctivities like weightlifting and I use it for that purpose during the res=
t of the year.  I have even found that it's beneficial for short rides (<=
40 miles).  Maybe someone else on the list can explain the physiology of =
creatine-induced cramping?
