Question

You are in charge of a cardiovascular laboratory. One day Stephan Curry (a well conditioned athlete) comes in and presents with a resting heart rate of 30BPM and a maximum heart rate after running on a treadmill of 190 BPM. Stephen is concerned because when he and his 3 year old daughter Riley both measured their heart rates at home together, his was 25 while hers was 100BPM. Is something wrong with Stephen or his daughter? How would you explain all these differences in heart rates? What would you expect Rileys heart rate to be if you were to test her on the treadmill

Explanation / Answer

Usually, the children have more heart rate than adults and under normal conditions the resting heart of beat of children, 3-6 years old is about 90-120 BPM (beats per minutes). The resting heart of beat of adults is about 60-100 BPM (beats per minutes). However, the well trained athletes have 30-60 BPM. So, from the data, the Stephen daughter is absolutely normal, but Stephen also has a normal BPM.

So, Stephen Curry is perfectly fine. In athletes, the cardiac output increases due to the regular exercise (stroke volume increases). During rest, the heart pumps enough blood to the body without much effort. The resting heart rate in athletes generally ranges from 30 to 40.
