Lactic Acid ?

Does that work Mish?. Haven’t had excercises done on my shoulders for years now. Even before hand I always had lactic acid. I heard it’s created in your guts by unspent adrenalin.. then travels to the muscles when working repetitively. I get buggered really quickly.

Actually lactic acid has nothing to do with joints.. or the LIVER!!. So I don’t know where you got or were going with that. It’s in my jaw when I EAT!. Or any muscle during repetitive muscle excercise. Athletes call it “hitting the brick wall”. Sodium Bicarbonate an help.

I did a little research into lactic acid:

“When muscles contract vigorously for long periods the circulatory system begins to lose ground in delivery of oxygen. In these conditions most of the pyruvic acid produced in the breakdown of glucose is converted to lactic acid (LA).

If your lactate threshold (LT) is reached at a low exercise intensity, it often means that the “oxidative energy systems” in your muscles are not working very well. If they were performing at a high level they would use oxygen to break lactate down to carbon dioxide and water, preventing lactate from pouring into the blood. If your LT is low it may mean that:

– You are not getting enough oxygen inside your muscle cells
– You do not have adequate concentrations of the enzymes necessary to oxidize pyruvate at high rates
– You do not have enough mitochondria in your muscle cells
– Your muscles, heart, and other tissues are not very good at extracting lactate from the blood

Improving your Lactate Threshold:
The aim is to saturate the muscles in lactic acid which will educate the body’s buffering mechanism (alkaline) to deal with it more effectively. The accumulation of lactate in working skeletal muscles is associated with fatigue of this system after 50 to 60 seconds of maximal effort. Sessions should comprise of one to five reps (depends on the athlete’s ability) with near to full recovery.”

It seems adrenalin and lactic acid are related:

” There will usually be some lactate entering the blood even at rest, because adrenalin and noradrenalin are produced in large amounts to compensate for hypothyroidism, and the adrenergic stimulation, besides mobilizing glucose from the glycogen stores, stimulates the production of lactate. The excess production of lactate displaces carbon dioxide from the blood, partly as a compensation for acidity. The increased impulse to breath (“ventilatory drive”) produced by adrenalin makes the problem worse, and lactate can promote the adrenergic response, in a vicious circle..

The idea of the “oxygen debt” produced by exercise or stress as being equivalent to the accumulation of lactic acid is far from accurate, but it’s true that activity increases the need for oxygen, and also increases the tendency to accumulate lactic acid, which can then be disposed of over an extended time, with the consumption of oxygen..”

They go on to say:

” The mere presence of lactic acid can make cells more susceptible to the transformation into cancer cells… [snip] by producing lactic acid “even in the presence of oxygen.” Lactate, a supposedly benign metabolite of the cancer cells, which appears in all the other degenerative conditions, including obesity, diabetes, Alzheimer’s disease, multiple sclerosis, is itself a central factor in the degenerative process.”

Nothing about water but rather oxygen intake. I do have diminished lung capacity as a result of quadriplegia. Some very interesting reading here:
