"Feel that burn!! Love that burn!!" Many a time in the crossfit gym, you've heard this shouted above the music. But, what exactly is the burn?? Lactic acid you say, almost as though it was a rhetorical question. I might have guessed that as well, except for the evidence that's proven otherwise over the last 20 years. In the book, "The Paleo Diet for Athletes" by Joe Friel and Fort Collins' own Loren Cordain, he explains, "...during an all out effort, your bloods's pH may drop as low as 6.4. In biomechanical terms, this is a huge acidic swing, producing a burning sensation in the working muscles and their inability to continue contracting. Fatigue has set in." Normal blood pH is 7.4, which is slightly alkaline. A 1 point swing is fairly significant with a scale that goes from 1-14.
So how do you avoid the burn. Well, I'm sorry to say that you can't completely avoid the burn. (Briton- avoiding intense exercise is not the correct answer, but nice try :) However, you can minimize it's lasting negative effects. You see, when your blood becomes acidic, your body compensates by releasing minerals (nitorgen and calcium) into the blood stream to balance the pH. Not a big deal, except that the calcium comes from your bones and the nitrogen from your muscles. Those things are pretty important, so to minimize the cannibalization (think Hannibal Lecter here), it's important to include Alkaline foods in your diet, particularlly right after a workout. Fruits and Veggies are the only Alkaline foods. Top five alkaline foods, ordered by their alkalinity, are Raisins, Spinach, Black Currants, Bananas and celery.
Raisins are especially good for a number of reasons, Stay tuned for more....
