It is because we need different amount of energy in different conditions of our body. When we rest we need less energy but when we do hard work we need more energy. Performing hard work is a difficult activity and it needs more energy. Thus, by increasing the breathing rate more energy is supplied to the cells for the production of more energy.

What happens to a persons resting heart rate when doing cardiorespratory exercise and conditioning?

It decreases because your heart no longer has to work as hard.


Why does an increase in pulse rate and breathing rate accompany exercise?

Your Breathing rate is increased due to the fact that your muscles are working harder then when they are at rest. This means that they need oxygen, along with sugars to complete cellular respiration. Your heart rate increases so that it can move the oxygen to the target cell in the muscles you are using quicker.


Why does your breathing rate change during exercise?

When you exercise the breathing rate increases because the body needs more oxygen to support your muscles. First off the heart rate increases which in turn speeds up how fast the air gets to the muscles or area being exercised then the oxygen is quickly used up then it needs to remove the by-product carbon dioxide which needs to be expelled quickly to allow more oxygen in.


How do you work out minute ventilation volume?

tidal volume x breathing rate


Does your heart rate and breathing rate go up or down at the end of the day?

it varies according to the kind of work you are doing.


What are some of the symptoms of heart failure in its early stages?

Typical symptoms of heart failure depend on which side of the heart fails. If the left side fails, the patient might display pulmonary edema and, in later stages, cyanosis. Increases in breathing rate and the work involved in breathing are also expected.


How does excercise affect your Pulse rate?

Fitness affects the pulse and breathing rate because the more your muscles are used the more they are used to the physical activity you are asking of them to do. Exercising puts a lot of pressure on your muscles and heart, if you are unfit it can make your heart work over time, increasing your heart and breathing rate.


How the heart respond to the strenuous exercise?

when you exercise, the heart rate increases, (as does your breathing pace), so that more oxygen can be carried in the blood to your muscles. The more intense the exercise, the more your muscles have to work, so more oxygen is required and your heart rate will increase. The quicker you heart rate returns to normal, the better your fitness.


Why do humans breathe slowly when they exercise?

The don't. Breathing rate increases fairly dramatically when exercising, unless said person is extremely fit (e.g. Lance Armstrong at his peak) and/or not doing any over;y exerting work.


What happens to your circulatory system when you ply football?

In the circulatory system, the heart rate increases and blood flow increses to the exercising muscles, and lessens to the other parts of the body. Your respiratory system doesn't change except for the amount of air flow. By Zahra Naiem


What happens to your breathing rate during a sprint?

During a sprint, your breathing rate increases significantly to supply your muscles with more oxygen and to expel carbon dioxide produced by heightened metabolic activity. This rapid breathing helps meet the increased demand for oxygen as your body works harder. Additionally, the heart rate also elevates, further enhancing blood flow and oxygen delivery to working muscles. Overall, the body's respiratory and cardiovascular systems work together to support intense physical exertion.


What neurogenic factors increase heart rate and breathing rate during exercise?

During exercise, the sympathetic nervous system is activated, leading to the release of neurotransmitters such as norepinephrine, which increases heart rate and enhances the force of cardiac contractions. Additionally, the brain's motor cortex and limbic system stimulate the respiratory centers in the brainstem, increasing breathing rate to meet the heightened oxygen demands of the body. These neurogenic factors work together to prepare the cardiovascular and respiratory systems for physical activity.
