I think it’s important to remember that you burn lactate, but H+ accumulation still leads to phsyiological changes that limit performance, specifically blocking the ability of calcium to bind to troponin. This is one of the reasons why the buffer capacity is important, ideally you can have large concentrations of lactate, with minimal changes in hydrogen ion concetration, because you will buffer out the changes in H+.
Acid is still “bad” it’s just they’re acknowledging the endurance preserving effect of lactate.
If my understanding is correct…
It is correct - good synopsis.
I just read this mainstream treatment (NY Times article) of the topic and while it’s good to get the message out, I think the message wasn’t as well presented as it could have been.
BTW, the exercise science community has known about this for years although it hasn’t reached mainstream consciousness – probably because people like to see things as black and white.
And in this case we’ve got lactate (dissociated form) being good, lactic acid (acid form) being bad.
And we’ve got this rogue something or other called H plus (H+) or, worse yet, hydrogen ions.
Whenever you introduce an element from the periodic table people crap their pants.
So let’s just stick with lactic acid making you burn and making you slow. It’s less confusing that way.
I don’t like to brag, but I did get a B+ in exercise physiology.
Thanks for chiming in on this thread JB. I knew when I saw it that it had the possibility of some solid intelectual discourse.
