Our experiment tested the effects of exercise on blood pressure. My partners and I would measure a test subject’s blood pressure after they had completed three exercises, walking, jumping, and performing jumping jacks until their blood pressure gauge reached 50 mmHg. We recorded jogging with the greatest change in both systolic (change in 26) and diastolic rate (change in 8). Our hypothesis was wrong as we thought jumping jacks would cause the great change as it requires the exercise of the entire body including all four limbs. “While doctors try to prevent coronary disease by treating high blood pressure and high cholesterol, it 's not 100 percent effective. If there are warning symptoms like angina with exercise, there is enough time to see a doctor and get started on effective treatments that reduce risk. Having a heart attack causes permanent damage, even if it doesn 't kill you.” - Mark Hlatky, Professor of Health Research and Policy (Health Services) and of Medicine (Cardiovascular Medicine) at Stanford University Blood Pressure What is it? First of all blood pressure, is the force of blood in the circulatory system and is calculated by measuring pressure and heartbeat rate and size of arteries. Systolic blood pressure is computation contractions of heart as it sends blood through the arteries. A normal systolic blood pressure is under …show more content…
We also conversed over the daily factors that can ultimately affect a person’s blood pressure, in which I have taken a keen interest. Since, we as humans are constantly moving and contorting our bodies into different positions such as walking and running. This conjecture is especially true when it comes to fitness which, gave me the idea of “How does exercising moves affect blood
Materials: This Cardiovascular activity was performed by different groups of students who were divided into groups of 4. A low step platform and stopwatch was used in both experiments of this study.
It was to this respect that, the search could detect ‘’hypertension’’ as the leading risk factor for heart disease. And this preceded three quarters of heart failures cases as compared to coronary artery disease, which led to most heart failures in less than 40% of the cases. Also, an increase in left ventricular end-diastolic diameter became a mirror to the Framingham study as incident heart diseases in the individuals who are free from myocardial infarction. Although studies have shown that, the manifestation of heart failures can be present without the left ventricular systolic dysfunction, other risk factors could lead to that. Also, they (Framingham study) were able to detect ‘’too much of cholesterol’’ as a link to cardiovascular diseases. Moreover, research believed that has elevated among certain heart diseases such as coronary heart often leads to stroke, too high blood pressure among numerous patients. Having said that, the search discovered ‘’obesity’’ also as a concomitantly with hypertension which elevates lipids and diabetes versus questions on smoking behavior. Having said that, these risk factors are believed to have attributed to heart diseases. Therefore, it became a national concern to the general US population and that of the fourth director of Framingham heart study, William Castelli
Why do we need to exercise? With out exercise many of our bodies arteries in the cardiovascular system can become clogged and bring on much unwanted cardiovascular diseases. Exercising regularly helps us maintain a healthy weight if already fi...
Marieb (1998) suggests that Blood Pressure may be defined as the force exerted by the blood against the walls of the arteries in which it is contained. Differences in blood pressure between different areas of the circulation provide the driving force that keeps the blood moving through the body.
Hypertension can be defined as a force exerted against the wall of blood vessels. However, high blood pressure occurs when there is high pressure at the time of ventricle contraction during the systolic phase against decrease contract during diastolic phase as the ventricles relax and refill. This can be recorded as systolic over diastolic in millimeters of mercury. (Wallymahmed, M. 2008).
Since 1960 the age-adjusted mortality rates for cardiovascular disease (CVD) has declined steadily in the U.S. due to multiple factors, but still remains one of the primary causes of morbidity and premature mortality worldwide. Greater control of risk factors and improved treatments for cardiovascular disease has significantly contributed to this decline (Centers for Disease Control and Prevention, 2011). In the U.S. alone it claims approximately 830,000 each year and accounts for 1/6 of all deaths under the age of 65 (Weiss and Lonnquist, 2011). Based on the 2007 mortality rate data an average of 1 death every 37 seconds is due to cardiovascular disease (Lloyd-Jones et al., 2009). Controlling and reducing risk factors is crucial for saving lives. There are a number of contributing risk factors for cardiovascular disease, which may appear in the form of hereditary, behavioral, and psychological, all of which ultimately converge in social or cultural factors.
One of the leading causes of death in the United States is heart disease. “Approximately every 29 seconds one American will have a heart attack, and once a minute one American will die from a heart attack” (Ford-Martin and Odle, 915). According to the Gale Encyclopedia of Alternative Medicine men over the age of 45 and women over the age of 55 are considered at risk for heart disease. Heart disease is a major cause of death. It is beneficial to individuals who seek to prevent heart disease to recognize the risks leading to heart attacks as they are one of the primary indications of developing heart disease; especially those that fall into the at risk age groups. These risks consist of some that cannot be changed such as heredity risks, or those that can change such as smoking habits. It is very important to know these specific risks for prevention and to understand the symptoms of heart attacks, such as sweating or the feeling of weakness so if these or other symptoms occur people are aware. Finally heart disease treatment is of vital importance if you experience a heart attack so you can learn how to prevent another one from occurring.

The plan and aim of this project is to select a group of six people and record their blood pressure, temperature, pulse and respiration whilst at rest. When they return from a brisk walk I will then record the same observations and analyse, evaluate the results. With this information I will then draw my conclusions and make recommendations.

Blood pressure is measured by two pressures; the systolic and diastolic. The systolic pressure, the top number, is the pressure in the arteries when the heart contracts. The diastolic pressure, the bottom number, measures the pressure between heartbeats. A normal blood pressure is when the systolic pressure is less than 120mmHg and Diastolic pressure is less than 80mmHg. Hypertension is diagnosed when the systolic pressure is greater than 140mmHg and the diastolic pressure is greater than 90mmHg. The physician may also ask about medical history, family history, life style habits, and medication use that could also contribute to hypertension
Remembering that prevention is the best cure, we are going to discuss what is high blood pressure, how to easily measure it, and how to effectively prevent it. (Thesis)
However there was no notable reduction in the magnitude of carotid atherosclerosis (9). The research was done over a single marathon event, more follow up research would have to be conducted to support reductions in atherosclerosis. An additional study has shown that aerobic exercise training can prevent further progression of atherosclerosis, but the arterial lesions and scarring cannot be reversed (8). This is important to understand, because once the damage is done to the arteries it cannot be reversed. In another piece of literature, it was suggested that an eight week long at home endurance based training program could reduce the arterial stiffness. This study found that aerobic exercise training did not improve artery stiffness or reduce blood pressure. However there was an increase in maximal oxygen uptake (3). There is suggestions that the short eight week study was too short term to show any changes in arterial stiffness, due to the arteries being resistant to short term modifications. A more lengthy study would better suite this type of research
Cardiovascular disease is very dangerous and it can lead to many serious problems. Such problems include atherosclerosis which can the increase of strokes or heart attacks. These strokes or heart attacks can be minor but some can possibly lead to death. There is also problems that can cause one to have cardiovascular disease such as being on an unhealthy diet, lack of exercise, or high blood pressure. To decrease the risk of these problems, a solution would be incorporating cardiovascular fitness into ones life. Some cardiovascular fitness exercises, can also be known as aerobic exercises, include jogging, running, walking, and swimming. Those who have high blood pressure are recommended to incorporate some sort of aerobic exercise in ones
