Simple biochemistry questions:
In the absense of oxygen, what happens to pyruvate?
When lactate is produced, specifically what does it quickly regenerate?
(Hint: It regenerates something in the glycoltic pathway.)
When rengeration of this sources occurs, what by-product is created?
(If you name the by-product right, do you see the problem now created?) If not, think again!
You've clearly hung onto the idea that lacate is "friendly / helpful," (which I can understand on the surface since you are taking Dr. Roberg's prose literally and without thought to possible couter-point(s)). But, have you considered that lacate is more than just a "fuel?" (By the way, it really isn't, directly, a fuel. It has to be converted to be one - and that mostly happens far away from the working muscle fibers.
The process of turning lactate into a fuel is time-consuming, plus it burns ATP and it causes elevated CO2. Respiratory acidosis occurs when CO2 rises to high. Lactate and respiratory acidosis generated from a remote location has a negative effect on local contraction force and velocity.
Example: Exercising one's arms vigorously elevates and dumps lactate into blood plasma, causing the Cori Cycle in the liever, heart, and kidneys to work hard. As a direct result of blood plasma lactate elevation due to arm exercises, contractile capacity in muscle fibers are reduced in both force and velocity.
IF LACTATE WAS SO GOOD FOR YOU, DOING ARM EXERCISES, WHICH DUMPS LACATE INTO YOUR BLOODSTREAM, WOULD "FUEL" YOUR LEGS, INDIRECTLY, AND CAUSE YOU TO HAVE GREATER POWER - RUNNING VELOCITY. IT DOESN'T HAPPEN!
The physiology behind remote lactate generation:
Lacate causes muscular fatigue by inhibiting excitation coupling of actin-myosin filaments(via reduced transience of calicum cations through sarcoplasmic reticulums?) Note, I a not quoting someone and forgetting to put the quotes around the information as some people do in debate. That's my interpreation of the information.
If you need a science source, read the following:
When you make a debate, be sure to include something other than repeated quotes from the same source. Break it down, make it your own, and actually KNOW what you are "talking" about. To keep saying that lacate is a buffer is shallow and shows a lack of either effort or real knowledge of what is going on.
Soon I'll end my side of this debate because I have restrictions on my time.
Recent mails sent to me have stated that you argue for the sake of arguing. I did not know this when the debate started. Thus, it seems pointless to continue much further when the path won't lead to enlightenment.
Now, I have to give my son a bottle; something far more important than typing discourse here.
