During the time of the exercise, both breathing and heart rate increase. Cells need more oxygen in order to burn glucose for energy. Cells need more glucose delivered to them and to have the product carbon dioxide away. Increased heart rate pumps the blood around faster to transport the materials. Increased breathing rate brings in oxygen and takes away carbon dioxide more quickly.
In a body that is conditioned by exercise, the resting heart rate and breathing rate would be slower than if the person did not exercise regularly. The heart would be more efficient, and the lungs may have more volume, so neither would have to perform at the usual rate.

breathing and heart rate both increase to get more oxygen to your muscles for respiration (to make energy)
