Lactic acid is produced during intense levels of exercise when the oxygen demands of the muscle fibers increase beyond what the blood is capable of delivering. To produce the energy needed, the body begins another process, which works in the absence of oxygen.ut lactic acid is completely washed out of the muscles within 30 to 60 minutes after you finish riding. Since muscle soreness does not show up until 24 to 36 hours later, scientists have been exercising their brains to come up with another explanation.
