An explanation of the data is that as exercise increases, more oxygen is needed by the muscles for cellular respiration to produce more energy , so the heart must beat faster to supply the O2 to the muscles.
What can you conclude about the effect of exercise on heart rate Why is this so what do your muscles need during exercise that the blood brings?
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest. The heart rate increases during exercise . The rate and depth of breathing increases – this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
What are the effects of exercise on heart rate?
Improves the muscles’ ability to pull oxygen out of the blood , reducing the need for the heart to pump more blood to the muscles. Reduces stress hormones that can put an extra burden on the heart. Works like a beta blocker to slow the heart rate and lower blood pressure.
What is the best exercise for heart?

How much: Ideally, at least 30 minutes a day, at least five days a week. Examples: Brisk walking, running, swimming, cycling, playing tennis and jumping rope. Heart-pumping aerobic exercise is the kind that doctors have in mind when they recommend at least 150 minutes per week of moderate activity.

Why does increased physical activity accelerates the heart rate and breathing rate?
When you are exercising, your muscles need extra oxygen—some three times as much as resting muscles. This need means that your heart starts pumping faster , which makes for a quicker pulse. Meanwhile, your lungs are also taking in more air, hence the harder breathing.
What is the relationship between exercise breathing rate and heart rate?
The more the heart beats , the more breathing occurs. As the heart beats faster, it uses more energy and sends more oxygen to the body. If a person is exercising the oxygen is used very quickly in order to provide the muscles with needed energy to move. Thus the heart beats faster to pump more oxygen to the muscles.
