lactate gets turned back into pyruvate which then gets turned into ATP again aye its a good thing and aye it took me a long long time to get this science right

We were just learning that Lactic Acid causes muscle soreness in my college level Prevention and Treatment of Athletic Injuries class. Haha. I wonder what the best way is to show this video to my teacher...

Calmly states that electric shocks caused fast twitches and movements that produce lactate and that lactate is good for you? maybe? Now looking at electrostatic to get a six pack.

So in theory could increasing the Lactate in your system help with muscle pain from exercise?

Some time ago i saw a program where they put an ultra-marathoner on a treadmill. This person does dawn to dusk runs for FUN! While on the treadmill they measured his lactate (acid?), and as he ran longer and longer the measurement went down!
