Measuring Blood Pressure During Exercise

Effect of Exercise on Arterial Pressure and Vascular Resistance Abbie DeBerg Ms. Brantley May 30, 2012

The purpose of arterial pressure and the pulse lab is to determine the effect of posture and exercise on systolic and diastolic pressure and the heart rate. And also in order to find the differences in the reading taken under these condition compares to the baseline reading. The Sphygmomanometer and stethoscope are used to measure the systolic and diastolic blood pressure, counting the beat on the radial artery will give the reading for pulse rate and by using the lab scribe software and IWX214, the blood pressure will be measured. In the heart, the aorta and the carotid arteries have baroreceptors and the chemoreceptors that identify the changes in arterial pressure and the changes in

Hypertension (HTN) is a chronic cardiovascular condition that is characterized by high blood pressure. The blood pressure commonly abbreviated as BP is a measure of the force exerted on the blood vessels as the blood passes through them. The amount of blood pumped and the narrowness of ones’ vessels are directly proportional to the blood pressure (Mayoclinic staff, 2014).

Why does Systolic BP increase when the participants start to exercise while diastolic remains constant when compared to standing?

Blood pressure (BP) as defined by Marieb and Hoehan (as cited in Peate & Wild, 2012) is the pressure that the blood puts on the blood vessel walls as the blood travels around the body controlled by the heart. The strength of the blood pushing on the blood vessel wall is the BP reading. According

Individuals who suffer from heart conditions, particularly adult and aged athletes are those who have had previously suffered from high blood pressure, experienced a heart attack or any other heart problems. Prescribed exercises for individuals within this group demonstrates low risk during participation and considerable health benefits. Health benefits through exercise reduces blood pressure levels, however in order to gain full benefits exercise must be linked with a balanced diet (low fat and low salt intake)

It is the measurement of the force of the blood pushing against the artery walls. A blood pressure cuff and a stethoscope is what are used to measure this. While taking you blood pressure two numbers are recorded; Systolic pressure and Diastolic pressure. Systolic pressure is the higher number that refers to the pressure inside the artery when the heart contracts and pumps blood through the body. Diastolic pressure is the lower number and refers to the pressure inside the artery when the heart is at rest and is filling with blood. Having high blood pressure can increase the risk of coronary heart disease (i.e. heart attack, stroke).

It was observed that the average systolic blood pressure did increase going from at rest to just after exercise (118 mmHg to 179.5 mmHg; Table 1.), however there was no significant difference between the two with a p-value of 0.063 (Table 2.). The average diastolic blood pressure increased slightly from 71.5 mmHg at rest to 79 mmHg after exercise (Table 1.); however, there was also no significant difference between the two with a p-value of 0.468 (Table 2.). The average HR between the at rest and just after exercise recordings also showed no significant difference (p-value = 0.056; Table 2.), however there was a general increase from 64.5 bpm to 80.5 bpm (Table 1.).

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

The purpose of lab six, is demonstrate how different activities like exercise, postural changes, and cognitive thinking change arterial pressure as well as heart rate. Blood pressure, which is abbreviated as BP is the force that is placed onto vessel walls by the blood that it contains. In healthy individuals, BP should be 120/80 mmHg, but recent research has shown that healthy individuals BP should be lower than 120/80 mmHg. The first number, in this case 120 is known as the systolic number. The systolic number is known as the amount of pressure placed onto the vessel wall by blood during ventricular contraction. When someone is taking another persons blood pressure, this is the first sound that the person will hear. This is because the blood vessel opened up enough to allow blood to begin passing through. The second number, 80 represents the diastolic number. The diastolic number represents when the vessel is relaxing and blood is getting through without any extra force. Also, this number is represented by the last sound an individual hears in their stethoscope. Aside from BP, heart rate also known as pulse rate, is the number of times a persons heart beats in a minute. (Marieb & Hoehn, 2014, pp. 708-710).

Blood pressure readings may be temporarily higher or lower throughout the day. They change after exercise, rest, pain, and when you are happy or sad. Occasional high blood pressure

The effects of exercise on blood pressure, heart rate, respiration rate and electrical activity of the heart were assessed. The measurements of respiration rate, pulse rate and blood pressures were noted as described in Harris-Haller (2016). Data was first taken from subjects in a relaxed position and then followed by sets of reading after exercising based on one minute intervals. The data also noted sitting ECG traces from Harris-Haller (2016). The respiratory rate, pulse, blood pressure, P wave, QRS complex and T wave were defined for each subject. The class average was calculated for males and females and graphed to illustrate the results by gender for each cardiopulmonary factor.

With the information found with what a patient’s blood pressure is, it helps health care providers understand the state of the patient’s health. A patient’s blood pressure measures the amount of pressure exerted on arterial walls in the patient’s heart. Blood pressure is measured in two numbers: systolic and diastolic. Systolic, the number listed first in blood pressure readings, reports the amount of force exerted by the blood into the arteries during ventricular contraction.

To start off the experiment, a baseline was needed in order to be able to compare the different variables through out the experiment. The subject was instructed to sit and relax quietly while the blood pressure cuff and pulse plethysmograph were placed properly. After the blood pressure was taken and analyzed, it was found that the subject’s blood pressure was 122/64 mm Hg and a pulse rate of 60 bpm. Now that the baseline was obtained, continuing with the changing variables could take place. Starting with the variable of postural changes, the subject first reclined for three minutes. After the two minutes, the

Carry out an experiment to measure the heart rate and ventilation rate before, during and after moderate exercise.
