Resting heart rate, maximum heart rate, target heart rate—what do all these numbers mean? What is the importance of these numbers and what criteria are used to determine them? What factors influence each of these signs of cardiac health? The purpose of this activity is to learn how these indicators are measured or determined and to investigate the effects of physical activity and additional weights on the heart rate.
