Lactic Acid

When you're in an anaerobic state you produce lactic acid? I did some HIIT today and my mouth was full of s**t I wanted to spit it out on the track but I tried to swallow it and that wasn't working. I just waited till I was done and spit it in the garbage.

Why does you're body produce lactic acid?
 
This is how I think of it. Your body is an hour glass. Lactic acid is the sand. When the sand is full on the bottom and empty on the top, it means you are done. The lactic acid is telling you that you need to stop.
 
hey guys im back.

Lactic acid is always being produced, it is just that when you train intensly more accumulates than what you can get rid of and therefore you feel the effects such as fatigue.

But answering your question, by the time glucose gets down to pyryvate, it needs to be converted to something else so energy keeps on flowing, becuase the aerobic system isnt fast enough it is converted tempoararily to lactate.

Once you start producing lactic acid you want to stop? I would want to go until I stop producing lactic acid

Pretty much

You want to do some forms of hard cardio training so you can improve your ' lactate threshold ' - which is the level of intensity at which lactate starts to build up in your muscles.
 
Also you should stretch a lot and if you have a really intense work out one day, lie on your bed afterwards with your legs up above your head for about 20 minutes - this will allow all the blood to flow out of your legs and when you stand up you can refresh you legs and prevent too much build up.

its inevitable,

The key factor is the point at which blood lactate starts to skyrocket, usually 4mmoles per L. The point which is commonly associated with OBLA, if you type that in google you might finding something to work on.

Essentially the harder and longer you can workout until OBLA the more "fitter" you will be, training in the OBLA zone will improve this. That is why lactate sampling or ventilatory threshold (less accurate) can be utilised for training purposes, something ive conducted in the past.
