Ted from Bangkok, Thailand replies: "Circulation problems of the leg and tiredness could be an electrolyte and buffer problems, along with the lost of certain vitamins as a result of excessive. Common electrolytes loss are sodium chloride (sea salt is best), potassium and magnesium. Take plenty of vitamin B complex and vitamin E, to reduce the cells need for oxygen. The body needs much more antioxidant than you need during an exercise.
The lactic acid buildup will be a problem and while some sports medicine says it is good, that the body can convert lactic to glycogen to further the energy requirements, my background in biochemist do not see it as helpful, since the liver is an imperfect factory that does not necessarily convert all of it and this create problems.
So in sports medicine, lactate buildup is really a no-no during training as lactate tends to destroy cells and mitochrondria reducing your energy output anyway. In fact doing this during training will almost guarantee that your athlete will loose the competition anyway. Since lactic acid buildup will kill an awful lot of cells and mitochrondia before the competition. Lactic acid will simply drain any energy. I don't know why these P.E. Teachers do that to students, unless of course they don't know what they are doing. Therefore the best solution is to use soda loading. Most athletes know soda loading by using sodium bicarbonate. That is actually an inferior form.
The use of citric acid + sodium bicarbonate (sodium citrate) is a preferred form. You can add potassium bicarbonate at 1/10 of the sodium bicabonate to get an ideal soda loading and some magnesium chloride (at 1/20 of sodium bicarbonate) should eliminate most of the problems.
Now taking vitamin B complex will help with the circulation, removal so of some fatty buildup that might block circulation can be helped with granulated lecithin taken everyday. If the problems persist than EDTA will be the way to go, but it takes a while longer. I prefer sodium EDTA orally (only small amounts) at less than 500 mg is the safe amount. This should help somewhat but it takes about 3 months to notice the full effect on your athletic performance after daily taking it."
