strength training
because when you exercise your muscles require more oxygen so your heart will beat faster to get the oxygen to the mucsles. since your blood goes through the lungs and your heart is beating faster you must breathe faster to get a sufficient amount of oxygen.
because the blood system is working harder
As you exercise, the muscles need more oxygen to work. The heart beats faster to get the oxygenated blood from the lungs to the muscles. The harder you exercise, the more oxygen the muscles need, the faster the heart beats.
When you exercise you breathe heavier and faster, your heart beats faster, your muscles hurt, and you sweat. These all relax when you finish exercising.
We breathe faster when we exercise to increase the amount of oxygen available to our bodies.
Your heart beats faster and you breathe more because your blood cells need more energy to give to your muscles
Your heart has to pump more blood through your veins because of the energy you are using to exercise so your heart has to pump faster and harder
yes, it does!

Lower air pressure means less oxygen. Means it's harder to keep your muscles supplied. You have to breathe faster and your heart has to pump faster
No, exercise doesn't increase the size of the heart. Exercise does strengthen the heart so that you can become more active in life.
Parts of your body, especially your muscles, require much more oxygen during exercise, which reaches them via your blood traveling through blood vessels. This means two things: your heart must beat faster to provide the oxygen more rapidly; and you must breathe faster and harder so that your lungs can oxygenate the blood.
