Best Answer

Exercising requires energy which requires oxygen to make. After the initial burst of energy is used up, not enough oxygen is being supplied to the heart so it then must work harder to pump blood. Therefore the lack of energy causes lack of oxygen causes heart to beat faster to compensate.
