Diastolic Heart Rate

Results Results from the experiment can be found below in table 2. As apparent in the table, with an increase in the intensity of the exercise, the heart rate and blood pressure both increased. An important observation from the data is that the systolic blood pressure steadily increased as we increased the intensity. However, the diastolic blood pressure remained relatively constant as the intensity of the exercise increased. The heart rate steadily increased with the increase of intensity as well.
Our Hypothesis was correct in the sense that we predicted the systolic pressure and heart rate levels will increase as we increase the intensity of the exercise. It was incorrect when we predicted that the diastolic would increase as well.

Because of this, it is necessary that the blood delivers more of these nutrients to muscles. In order to do this, the cardiovascular system must increase cardiac output and dilate the blood vessels. Cardiac output can be increased in two ways: increasing stroke volume and increasing heart rate. An increase in stroke volume will result in a corresponding increase in systolic blood pressure because this is the pressure that results from the contraction of the left ventricle. So, a greater output per stroke of the heart will cause the blood vessels to have a greater pressure exerted on them. Diastolic pressure, on the other hand, is a measurement of pressure on arterial walls between heartbeats. Because the arteries dilate, there should be a minimal change in diastolic blood pressure with exercise. In addition, a greater rigor of exercise will result in a greater increase in heart rate and blood pressure, again due to the greater need the muscles have for
