carbohydrate molecules

Glycolysis (breakdown of carbohydrates) results in the formation of pyruvic acid and hydrogen ions (H+). A build up of H+ will make the muscle cells acidic and interfere with their operation so carrier molecules, called nicotinamide adenine dinucleotide (NAD+), remove the H+. Also by removing/blocking it will it result in better absorption of these supplements which actually result in better recovery. I guess I m just thinking out loud here not trying to promote product or anything. If there is insufficient oxygen then NADH cannot release the H+ and they build up in the cell. In non athletes this point is about 50% to 60% VO2 max and in trained athletes around 70% to 80% VO2 max. It s there to be broken down and help muscles. I d also like to note I ve been known to be way off base so that s why I ask for input. I d love so see what you guys think about this. My question/hypotheses is that, is lactic acid build up inhibiting the effect of the quick release supplements we take. So from what I gather here is simply that intense workouts can and in most of us will cause the development of lactic acid which dose affect performance. Some of the lactate diffuses into the blood stream and takes some H+ with it as a way of reducing the H+ concentration in the muscle cell. The NAD+ is reduced to NADH which deposit the H+ at the electron transport gate (ETC) in the mitrochondria to be combined with oxygen to form water (H2O). The lactic acid system is capable of releasing energy to resynthesise ATP without the involvement of oxygen and is called anaerobic glycolysis.
