Let's begin splitting hairs.<BR/><BR/><BR/>It's really ATP hydrolysis that causes all the muscle pain. The Lactic Acid <-> Lactate buffer<BR/>helps attenuate the effects of ATP hydrolysis.<BR/><BR/>There are many competing metabolic pathways in action during exercise, lets draw a box around one of them<BR/>(don't laugh, this is serious). <BR/><BR/>During anaerobic metabolism, ATP hydrolysis causes a high rate of hydrogen<BR/>ions to accumulate and lower the blood pH (acidosis). ATP is just an energy store molecule for muscle.<BR/><BR/>The Lactic Acid <-> Lactate buffer in your blood serves to reduce the hydrogen ion accumulation<BR/>produced by ATP, ie, Lactate becomes Lactic Acid. At some point your body cannot remove the Lactic<BR/>Acid to help buffer ATP hydrolysis (threshold reached: Lactate cannot remove anymore hydrogen ions <BR/>and form Lactic Acid). <BR/><BR/>In the end, no matter how much pain you're in, pushing hard on the pedals is impossible since all<BR/>the metabolic pathways we have not talked about are shifting left and right (that's a technical term).<BR/><BR/>John P.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-35529945.post-72119623261657832892008-01-30T09:32:00.000-08:002008-01-30T09:32:00.000-08:00Yeah, the sprints.
