Why does your heart and breathing rate change after exercise?

Answer 1

The breathing rate decreases due to an increase in lung capacity, this means that you have a larger tidal volume meaning you do not have to breathe as frequently to inhale the same amount of air per minute

Answer 2

When we exercise, we burn more calories. In order to burn calories, the body requires oxygen. As the need for oxygen increases, the body thrives to fulfil the oxygen requirement from the lungs and pulls in more oxygen. This increases the breathing rate.

Answer 3

When you are exercising, your sympathetic nervous system (aka "fight or flight") causes your heart rate, blood pressure, and breathing to increases, so that you have the energy to work. Afterwards, when you've slowed down, your parasympathetic system (aka "feed and breathe") takes over, bringing all the previously mentioned back down, while the body recuperates.

Answer 4

Your breathing rate changes because your muscles need more oxygen to keep working & repairing so the only way to get more oxygen is to breath more heavly and faster :)

Hope this helped:)!

Answer 5

Because your exercising your muscles are using more oxygen. In order for your body to keep working and keep up with the amount of oxygen your body is needing, it speeds up the breathing. This gets more oxygen in and flowing to your muscles.

If you muscles just relied on the amount of oxygen you got in with a normal breathing rate, you wouldn't get far.

Answer 6

Because the blood carrying the oxygen round your body has to get to places in your body quickly, because the cells in your body are working harder and need more oxygen. ( oxygen + glucose(sugar) -> energy, carbon dioxide and water.)

Answer 7

because the intecostal muscles and the diapharm become stronger
