Cramping Lesson(3 posts)

Yesterday I rode 42 miles and was plagued by cramping in my left calf. I'm in the last stages of dialing in my new bike, and I was contemplating how a few millimeters of saddle position change could cause such cramping when I remembered that I had run out of mineral suppliments a few day ago. Got my suppliment (Iron, Chromium, Maganese, Potassium, Calcium, Phosphorus, Zinc, Selenium, Copper) and took it last night and this morning. Rode 60 miles today: NO CRAMPS. Not even close.

Moral of the story: Boys and Girls, take your vitamins!

There are several theories of cramp causes (none proven) but only potassium and calcium among the minerals (not vitamins!) you list are possibly implicated in cramping.

For reference: Adventure Cyclist Sept/Oct. 2001 Muscle Cramps comments by Nancy Clark

5 theories (none proven, as science does not know the cause of cramps, and cannot cause cramps predictably): 1) hydration, 2) lack of calcium (doubted by nutritionists), 3) lack of sodium, 4) lack of potassium (not likely since the body has so much) 5) lack of pickle juice (lots of ions). Note, musicians get hand cramps, even though they are not likely experiencing any of 1-5.

My own experience has been that sodium and hydration are the keys. This assumes you keep a high cadence.

i used to cramp until i started on calcium and magnesium supplements. not sure if there were other variables in play but cramped badly in 2 races, 3 weeks later was fine.
