First, you must understand metabolism. This is the process in the body (any animal body) that turns stored energy into mechanical movement. Metabolism starts when foods are broken down and converted into glucose or similar sugars. The so-called Krebs Cycle in each and every cell of your body converts glucose into a powerful molecule called ATP. Think of ATP as a teensy, one-shot battery.
Every time you move a muscle, ATP created in the cells of that muscle go 'ker-pow' -- and provide the energy for that muscle to move. In the process, ATP degrades into ADP, which must go back and get re-energized in the Krebs Cycle. But something else happens in the muscle. Various proteins and enzymes that move the ATP and ADP around, shed little molecules in the process. And the Krebs Cycle itself, sheds little molecules.
These little molecules, "fatigue poisons", must be swept out of the cell, picked up in the blood and filtered out (or recycled) by the kidneys and liver. One of these molecules is called Lactic Acid.
You are quite capable of moving your muscles so hard and fast, that you produce fatigue poisons faster than they can be swept out of the muscle cells. They begin to accumulate in the muscles. They interfere with the proteins that move the ATP and ADP around, until finally, your muscle cells just cannot get enough ATP to move.
Then you fall down.
No, there is no way to stop them from being produced. They are produced by the central energy process in every cell of your body.
