Everything you think about lactic acid is wrong
It turns out that science has been wrong for 80 years. A buildup of lactic acid does not cause your muscles to burn or tire or eventually become sore. Actually your body converts glucose to lactic acid, and your muscles use the lactic acid as fuel. So pro athletes who have an extremely high level of lactic acid in their blood are not ‘tolerating’ it, they are actually adept at producing high levels of it thereby outputting high performace. So lactate threshold is a complete farce. Oh well, lets just call it aerobic threshold amonst friends. More details in the NY Times here.
