What is the relationship between oxygen debt and muscle fatigue and an elevated respiratory rate after exercise ?

Question

anonymous · Answer

When muscle fatigue occurs it's almost as if the systems in ones body have shut down, this is where  oxygen debt come in as when this happens,  the oxygen levels and systems in question become restored to their original  state. Muscle fatigue usually occurs after a certain intensity of a workout, typically something you're not use too

Elevated respiratory rate is caused by the lack of oxygen in the body
The lack of oxygen causes lactic acid to build up , which causes soreness and pain (muscle fatigue)
Oxygen debt is the amount of oxygen needed to convert lactic acid to H2O and CO2 (as the body doesn't want lactic acid to present in the body)
