Both your roommate (19 years old and a volleyball player) and your landlord (65 years old with heart disease) have the same resting heart rate of 54 bpm. Is this resting heart rate normal for your roommate and for your landlord? Why? Discuss the condition
What will be an ideal response?
It is normal for the roommate because the roommate is an athlete. Without a pathological condition, a lower resting heart rate indicates a stronger heart. To adapt to cardiorespiratory or aerobic exercise, blood volume increases, the heart enlarges, and the muscle gets stronger. A stronger heart can pump more blood with fewer strokes. Resting heart rate decreases with training; the extent of bradycardia depends not only on the amount of training but also on genetic factors. For most individuals, however, the resting heart rate decreases as the level of cardiorespiratory endurance increases.
It might be abnormal for the landlord because the landlord is older and has heart disease. The diseased heart could be the reason for the landlord's bradycardia.
