Answer 1

Answer:

lack of oxygen

Explanation:

as we start our exercise we start to consume more oxygen, which means we take O2 from blood and the blood starts to work in more speed as the need for more 02 rises, because your muscles need it. When the amount of oxygen needed is not supplied, lactic acid is produced in our blood stream, as your body can break down the lactic acid into energy without oxygen.
