As you do more exercise, your heart gets stronger and has more stroke volume leading to more oxygen to go round the body. As there is more oxygen going round the body, the heart does not work as heart.
Since you are exercising your pulse rate goes faster.
While actually exercising will cause your pulse rate to increase, when you are fitter your resting rate will be lower than before.
while you smoke your pulse rate increases
Of course exersizing increases heart rate
to not let your heart rate go too high
adrenaline, sexual arousal, exercising, breathing fast, etc.
By doing exercises our pulse rate will increase to 50-75% of our maximum heart rate, because of this action more blood pumps to our organs.
after the same time as you were exercising e.g.(you were exercising for 5 minutes then it will go back after 5 or 4 minutes)
decrease
The pulse rate is determined by how much blood the heart pumps per beat vs how much blood flow is needed to maintain proper oxygenation. The best way to decrease the pulse rate is to make the heart a more efficient pump, making it pump more with each beat. The most effective and safest way to do this is to exercise. As the body gets into better shape, the heart will strengthen and will be able to pump more blood with each beat, and thus lowering the pulse rate. As a result of exercise, some well trained athletes have pulse rates in the upper 40's to low 50's.
You'll have an oxygen deficiency that'll have to be compensated for before the pulse an breath rate will be back to normal.
Yes, exercising does cause your pulse to increase.
