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?
A1A strong athletic heart gets more cardiac output per stroke.
Less strokes = more movement of blood per stoke

A2That is like asking why a wild trout lives in water. The heart muscle become stronger and bigger, and can pump more blood per stroke. It needs fewer strokes to get the same amount of blood to all the places it is needed.

Q. I had my blood test as I was feeling dizzy and my heart rate was raised & I was diagnosed with hyperthyroidism

I had my blood test as I was feeling dizzy and my heart rate was raised & I was diagnosed with hyperthyroidism. It had just started when I was taking herbs for depression and anxiety. I am not taking herbs now and still feeling dizzy. Has anyone had any problem with Chinese herbs?
AMy mom had hyperthyroidism, but not with herbs. Until she told the exact things to the doctor, her treatment was difficult and once she revealed the medicine history to the doctor she was very well treated. Similarly I expect from you to tell your doctor about the herbs you are taking and you must tell this to your Chinese medicine practitioner as well. There are chances that you may have high level of thyroid and these herbs just boosted them or increased them as Chinese medicine do not have high side effects. Please open to your doctor during investigation and treatment.
