Many may question why their muscles feel tense, ache, and cramp after a vigorous workout, whether it is swimming, playing basketball, riding a bike, or any other physical activity. The reason why this pain may occur is also found in sour milk, yogurt, molasses, and in fruits. Lactic acid is the culprit.
Lactic acid is described as a “colorless, water-soluble liquid that freezes, or solidifies, at 64.4°F (18°C) –just slightly below normal room temperature,” according to the Gale Encyclopedia of Science. Other names for this acid include the scientific name alpha-hydroxypropanoic, 2-hydroxypropanoic, and the informal name milk acid. Its chemical formula is C3H603 and it is a weak acid in liquid solution.
The product of anaerobic respiration, the burning of stored sugars without sufficient oxygen by cells, is lactic acid. Not to be confused with aerobic respiration where there is enough oxygen to fully utilize the stored sugar energy. Chemically, anaerobic respiration causes the halving of glucose molecules (C6H1206) into lactic acid molecules (C3H603). This builds up in muscles, which leads to soreness and may often lead to cramps as well.
Lactic acid fermentation stops only once the body slows down and oxygen becomes available. The body can adapt to lactic acid build up and may be able to become immune to it to a degree. What is meant by that is that an Olympian athlete is less likely to develop cramps and aches than a person who is just getting back in shape is.
Athletes can prevent these cramps and aches by doing the following: increase their calcium, vitamin C, magnesium, lecithin, and protein. The best way to be sure that you are getting enough of these vitamins and minerals is to make sure to eat a diet with at least 5-7 portions of fruit and vegetables per day. Another option is actually increasing lactic acid intakes, itself. Foods such as, olives, sauerkraut, cheese, soft drinks, pickles all contain an amble amount of...
