However, here is my recollection of the formation of the hydrogen ions within glycolysis: <BR/><BR/>- NAD+ strips two electrons from the substrate (C6H12O6) for formation of NADH (and H+) and eventual entry into the respiratory chain, i.e. the Hydrogen atom is positively charged because the NAD steals two electrons from it.<BR/><BR/>All is fine and dandy providing we have enough NAD+ and enough O2. A lack of either will result in the body creating a temporary store of the Hydrogen in the form of lactic acid. However, this process is limited and in reality it is the beginning of the end. <BR/><BR/>Cheers,<BR/><BR/>ACAlan Couzenshttps://www.blogger.com/profile/07123240819644335101noreply@blogger.comtag:blogger.com,1999:blog-7915222980782433094.post-57792013949594185862008-09-25T07:10:00.000-07:002008-09-25T07:10:00.000-07:00Hey James,In the context of the lactate curve, y a...Hey James,<BR/><BR/>In the context of the lactate curve, y axis is mmol/L. <BR/><BR/>In fat oxidation, y axis represents kcal/min <BR/><BR/>Cheers,<BR/><BR/>ACAlan Couzenshttps://www.blogger.com/profile/07123240819644335101noreply@blogger.comtag:blogger.com,1999:blog-7915222980782433094.post-36542371574169027512008-09-25T03:10:00.000-07:002008-09-25T03:10:00.000-07:00AC, For the 2 graphs (and any to follow as you...AC,<BR/> For the 2 graphs (and any to follow as you continue our "class") could you define the X and Y axis? X axis is obviously %VO2max but I'm unclear as to how lactate is commonly expressed in your world. umoles, mmoles, mmoles/ml???jamiejhttps://www.blogger.com/profile/00522842012790774743noreply@blogger.comtag:blogger.com,1999:blog-7915222980782433094.post-66351482035044114272008-09-24T13:48:00.000-07:002008-09-24T13:48:00.000-07:00Great stuff AC.

We would use "protons" but that is neither here nor there. <BR/>I would be really interested in seeing "EC approved" field tests for all indicators such as AeT, FTP, MAF etc. Perhaps it would prove valuable to the launch of the new site as we could all "speak" in a common language based on commonly accepted EC tests. I don't really have easy access to a met cart unless Mat brings it back to Indy for Thanksgiving!jamiejhttps://www.blogger.com/profile/00522842012790774743noreply@blogger.com
