Electrolytes... the fluids normally in contact with the internal and external surfaces of cells are essentially solutions of electrolytes and therefore good conductors of electricity, which is one of their functions.

The concentrations of electrolytes inside and outside the cell membrane determined responsiveness of a cell and speed of conduction of current along a fiber. For example if K+ increases outside of a cell as it does during exercise that triggers hyperventilation, response is diminished. Exercise physiology that doesn't take into consideration the uptake of electrolytes as well as oxygen, from inhaled air (as Body'Fit pH Fitness breathing is designed to enhance) finds it difficult to understand, for example, why oxygenated venous blood destroys the vasodilator effect of potassium.

The sodium (Na+) ion which is critical in the electrical activity of cellular metabolim, is required to neutralize anions that replace bicarbonate (HCO3-) in the plasma during metabolic acidosis. The stores of Na+ are not depleted unless the acid load is very high as during prolonged strenuous exercise, however they limit the metabolic activity of other cells of the body when they are temporarly reduced.

It has been known since antiquity that pH (determined by observation in Chinese medicine) must be balanced in order to absorb ions ("chi"). Maintaining the proper balance of ions during exercise will restore normal slightly alkaline pH, and help prevent the circulatory imbalance that would otherwise occur. If the pH stays normal as metabolism increases, it gives the cells an opportunity to increase supply of electrolytes as demand increases. This accelerates rate of repair making up for the cellular wear and tear caused by strenuous activity. Body'Fit pH Fitness produces conditions that increase absorption of electrolytes, and prevents acidic pH conditions that would otherwise use up electrolytes in attempt to rebalance acid base rather than repair the body.
