As you exercise, your muscles demand more oxygen. Oxygen is taken to the muscles in your blood. More blood equals more oxygen. To send more blood, the heart has to pump faster. Your heart pumping is your pulse. Faster heart, faster pulse.

The blood forced out of the heart into the aorta moves sets up a pressure wave that travels along the arteries which expands the walls. this expansion is palpable as pulse. With increased heart rate to compensate the increased oxygen demand due to activity increases the pulse rate.

When you perform exercise,the muscles in the body demand more oxygen to combine with the carbohydrates and form energy required to sustain the exercise.The heart responds by beating faster to meet this increased demand and thus the high pulse rate.At the same time in the mid brain are PH sensors which are sensitive to increase in carbon dioxide levels.These are responsible for the increase in the rate of respirations and thus the rate of of excretion of carbondioxide from the body via lungs.
