Detailed explanation-1: -You can’t keep up anaerobic-level intensity for long because the build up of lactic acid leads to a reduction in your speed and power.
Detailed explanation-2: -Most tissues of the body can live without O2 for several minutes and some for as long as 30 minutes. During this time, the tissue cells obtain their energy through processes of anaerobic metabolism, which means release of energy by partially breaking down glucose and glycogen but without combining these with O2.
Detailed explanation-3: -During vigorous exercise our muscle cells sometimes resort to fermentation when there isn’t enough oxygen present. We don’t use fermentation as our main means of producing ATP because it only produces 2 ATPs whereas aerobic respiration produces 38. Furthermore, lactic acid is produced during fermentation.
Detailed explanation-4: -Inadequate oxygen drives muscles towards anaerobic respiration. Partial breakdown of glucose leads to lower energy production.
