Why does a sprinter continue to breathe heavily for several minutes after finishing a race?

Answer 1

Because during the race the athlete will have built up an oxygen debt (obtained energy without full use of oxygen) that needs to be corrected once the exercise stops.

Answer 2

Oxygen is heavily used to make ATP for cellular respiration in the electron transport chain. ATP is used for muscle contraction. There is something called the "oxygen debt" that must be "repaid" after heavy exercise or a race. They body tries to do this with deep and frequent breathing.

Answer 3

Energy comes from respiration. Normally we combine glucose with oxygen to produce carbon dioxide and water and release energy. During heavy exercise we can't absorb enough oxygen to keep up with our energy needs, so we also employ a process called anaerobic respiration, where glucose is converted to lactic acid to release energy without the need for oxygen. This gives us a temporary energy boost, but lactic acid is toxic so we need to get rid of it. We do this by combining it with oxygen to convert it to safer substances. This means that we need to keep breathing heavily until we have got rid of all the lactic acid.

Answer 4

Everyone breathes heavy after exercise. It's because when you move more, your heart needs to pump faster go get blood to your body. There needs to be a certain amount if oxygen in the blood, so you breathe short breaths faster to keep up with your heart.

Answer 5

You breathe heavily after a run because if you notice, your heart beats faster and so it needs more oxygen for it to pump blood.

Answer 6

because it gets your heart beating faster as you are moving faster

Answer 7

because there oxygen debt has run out and that is why they are still breathing heavily after their race.

Answer 8

Cellular respiration
