Patient discussion about lower rate.

Q. Why do people with a better cardiovascular fitness have lower heart rate? I recently met my old friend and that too after long time. We did go out and had a blast. He did show me his medical report and I was shocked to find out that he was having lower heart rate than me but was having better cardiovascular. He told me that it was quite normal but It was bothering me a lot. How could it be possible and I do see this as a deficiency. My friend does not agree with me and he told me that nothing to worry. I did try to research and found nothing with this regards. I am unable to sleep and would like to know on this. Can someone help me with answers?. Why do people with a better cardiovascular fitness have lower heart rate?

A. A strong athletic heart gets more cardiac output per stroke.
Less strokes = more movement of blood per stoke
