The answer to this question would be: <span>During anaerobic respiration, lactate levels increase when muscles cells need more energy. However, muscles cells eventually fatigue, thus athletes should modify their activities to increase aerobic respiration.
Lactate will be produced when the muscle cells doing anaerobic respiration. The lactate can be accumulated in the cells causing the muscle to be fatigue. Using the information from the tattoo the athlete can adjust their exercise intensity to prevent the accumulation.
