When muscles are used for exercise, they must be replenished with oxygen, nutrients, etc. They also produce waste products that need to be taken away from the cells. Blood is the transport system for all of these things, so the harder your muscles are worked, the quicker they burn through nutrients and produce waste, meaning that the blood must flow faster to provide all of this; the only way for blood to flow faster is for your heart to beat faster.
Resting muscle gets about 750 ml of blood out of your 5 liters of cardiac out put. During exercise the cardiac output may go up to 25 liters per minute. Out of these 25 liters of cardiac out put, your muscles get about 20 liters of blood to meet the metabolic requirements of oxygen and food material. The stroke volume of heart increases but then heart rate also increases from 72 per minute to up to 180 beats per minute.

What does exercise do to the heartbeat?
the more you exercise, the faster your heart beat is. this type of exercise is called cardiovascular exercise. (cardio for short) this strengthens your heartbeat. exercise makes the heartbeat faster because for example: the faster you run, do you notice you panting? your body needs all the oxygen it can get when exercising.
What can you infer from the fact that your heart beats faster when you exercise?
You can infer that your (healthy) heart is beating faster to compensate for the extra effort your body is making during physical exercise. Once the exercise is over, the time the heart takes to become relaxed and to return to a normal resting beat is a good indication of the state of the health of your heart.
Why does heart rate and respiration go up with exercise?
The more you exercise - the more oxygen your body's muscles need. In order for your heart to supply more oxygen - it must beat faster.
