Sorry to shatter your dreams of playing ironman at tour and not getting tired but having read that article I don't think just eating more calcium is the answer. It says the problem is leaking calcium pumps not a deficiency of calcium. And call me a sceptic but I'll wait until I see it In a scientific journal rather than a newspaper too...
Until then I'll be using the track to get fit.

Long live calcium! To: ulti NYC-ultimate <[EMAIL PROTECTED]>, ulti Asheville < [EMAIL PROTECTED]>, eurodisc <[EMAIL PROTECTED]> Hey Ultimate, http://www.nytimes.com/2008/02/12/health/research/12musc.html?em&ex=12030516 00&en=627f6a21952d029a&ei=5087%0A Read this article if you still think lactic acid has something to do with fatiguing muscles. That experiment was done on dead frogs over 100 yrs ago -- the scientist was prodding dead frog muscles to make them twitch, and when they stopped twitching (remember, they were dead), he noticed that the muscles were saturated with higher levels of lactic acid. Hence.... This article underscores the importance of CALCIUM for making muscles function. I remember from undergrad biochem something about calcium channels, and the absence of calcium in muscles causing spasming. The thing about the false lactic acid theory was that the folk wisdom about how to keep muscles un-fatigued has been functionally appropriate over the years. Drinking water and keeping up electrolytes are good. Avoiding milk and other dairy products -- that is still probably good advice since dairy causes mucus; though the fat in cheese is good during tournament time for energy -- but not during training. There are better sources of calcium than dairy: -- green leafy vegetables -- broccoli, parsley, kale (but not spinach -- the iron is accessible but the calcium is bound and inaccessible); -- tofu and other soy products; -- almonds; -- brazil nuts; -- molasses; -- figs are a great source, and generally a good natural alternative to Power Bars as they also have electrolytes & potassium. Keep on chucking, Melle __________________________________________________ BritDisc mailing list [email protected] http://www.fysh.org/cgi-bin/mailman/listinfo/britdisc Staying informed - http://www.ukultimate.com/staying-informed
