How does fitness effect breathing and heart rates?

Answer 1

The faster you breathe the faster your heart rate gets (more oxygen to pump around)

The slower you breathe the slower your heart rate gets.

Although correct, this answer does not explain why your heart rate increases. If you are breathing quickly, you are not getting as much oxygen in as if you were breathing normally. Therefore, your heart rate increases because your heart is trying desperately to pump the required oxygen throughout the body that isn't available. For example, if a restaurant is understaffed, the remaining workers will work twice as hard. With not enough oxygen, your heart needs to work harder to deliver the available oxygen.

The deeper breaths you take, the slower your heart rate will be, due to the excess of oxygen; your heart won't need to work as hard with lots of oxygen available.

Answer 2

Both are controlled by the brain stem, the medulla oblongatta, which coordinates the breathing rate by monitoring the amount of carbon-dioxide the is in to blood. The breathing rate then can accommodate changes in the cardiovascular system. If it has too much carbon-dioxide then the breathing rate is increased to bring in more oxygen. =Answer= Breathing rate influences heart rate. During normal sinus rhythm of the heart, breathing causes respiratory arrhythmia - a fluctuation in heart rate. As you take a breath you increase thoracic pressure, this promotes venous return to the heart, which will cause an increase in heart rate. As you exhale, thoracic pressure decreases and this decreases venous return and thus reduces heart rate. This fluctuation in pressure and heart rate is relatively small and does not cause any significant effects on normal function.

Answer 3

Conditioning through exercise lowers the peripheral resistance to blood flow though the muscles and leads to an increased stroke volume and a decreased heart rate. Respiration rates also decrease. Most of this follows the increased efficiency of muscle to utilize 02 after conditioning. (Berne and Levy, 1988)

Answer 4

When you hold your breath, you stop getting oxygen in your lungs that go to your heart. The oxygen level in the blood drops, so your muscles need more oxygen, so the heart pumps faster. This is like running, your muscles need more oxygen so heart pumps faster.

Answer 5

When you hold your breath, you stop getting Oxygen in your Lungs that go to your Heart. The Oxygen level in the Blood drops, but your Muscles need the Oxygen. As a result, the Heart pumps faster. Compare it to running; your Muscles need more Oxygen so Heart pumps faster.

Answer 6

yes. it decreases with expiration and increases with inspiration. This is measured using an EKG (or ECG) by measuring the R-R interval.

Answer 7

The person would breathe more heavily which should make blood pump around your body more so your heart should beat more faster! :)

Answer 8

Your heart takes in the oxygen you breathe in to pump more blood. So,the more you breathe in,the more oxygen. The more oxygen,the faster your heart rate is!
