Scientific method and data analysisa biology student wanted to determine if there is a relationship between resting heart rate and bodyheight. she gathered information from 12 classmates and constructed the table below. resting heart rate (beats per minute)student height (cm)155. 156156165180180190194195​

YES, there is a relationship between resting heart rate and physical activity.

The higher the physical activity, the better the physical performance, the better the cardiac contractile quality, therefore the lower the heart rate at rest.

Explanation:

The heart is a muscle that is trained like the rest, when practicing physical activity it contracts and expels blood more often and more intensely.

Thus generating that the contractile power is more effective, that is to say that in each bombardment it ejects more blood into the aorta, therefore there will be less effort at rest.

This is how training generates hypertrophy of myocytes, they contract better, generate blood ejection to the vascular system in a more efficient contraction compared to sedentary, therefore the oxygenated volume will not have to be replaced immediately, thus generating the heart have to beat or eject more slowly.

By contracting fewer times per minute, we are faced with the phenomenon of decreased heart rate, this is measurable by taking the pulse of an athlete at rest and comparing it with a sedentary person also at rest.
