gangadharan_nair is correct. Normal people breath to get rid of carbon dioxide. Carbon dioxide is produced by the body from everyday activity. If you increase that activity, your body will produce more carbon dioxide. So you body will increase the breathing rate to blow it off.

RE:
Why does your rate of breathing increase during exercise?

Because you are expending more energy and you need to increase your oxygen intake and get rid of carbon dioxide more quickly.
During vigorous exercise, ventilation can be increased from the resting level of about 8 litres per minute to well over 90 litres per minute (may be as high as 120 litres per minute) through an increase in the rate and depth of breathing. The increase in ventilation is so remarkably attuned to the metabolic need of the body that, except in the most exhaustive type of exercise, CO2 is exhaled as fast as it is produced by the active tissues

While exercising, the level of carbon dioxide in the blood increases due to increased cellular respiration by the muscles, and so breathing rate increases.
When carbon dioxide levels increase in the blood, it reacts with the water in blood, producing carbonic acid. The drop in the blood's pH will then cause the medulla oblongata signalling center in the brain to send nerve impulses to the diaphragm and the intercostal muscles, increasing the rate of breathing.
During rest, the level of carbon dioxide is lower, so breathing rate is lower. This ensures an appropriate amount of oxygen is delivered to the muscles and other organs.

Increased muscle activity also increases the demand for oxygen. This is because oxygen is needed during cell metabolism (ATP). The demand for oxygen goes up as your skeletal muscles and your cardiac muscles demand it. The brain then increases your respiratory rate to rid the body of carbon dioxide and increase in take of vital oxygen.

Because your demand for oxygen increases, and the only way your body gets oxygen is by breathing.

More oxygen in the blood to feed the muscles and organs

moving muscles require more oxygen, so your lungs step up the intake.
