Distance Other studies have attempted to measure the effect of distance on blood pressure response in order to find if there is any correlation between distance and a significant blood pressure reduction. One of these studies (see Moreau et al, 2001) involved 24 sedentary post-menopausal American women (15 in the intervention group ) with high blood pressure. The results found that, after a 2-year walking programme, that there was a statistically significant drop of 13 mmHg in the systolic blood pressure of those participants who were taking anti-hypertensive drugs and of 11 mmHg in those not receiving medication, whereas there was no difference found in their diastolic blood pressure and in the blood pressure of the control group. The participants in the intervention group were instructed to walk 3 kms per day in addition to their normal daily physical activity. After the first year the reduction in blood pressure was significant: 6 mm Hg in the systolic blood pressure of the participants who were taking anti-hypertensive medication and 7mmHg in the non-medication group. In this study , the magnitude of the reduction of systolic blood pressure as a result of a walking programme is similar to that which has been found in earlier studies in response to traditional exercise (see Seals et al,1997, and Hagberg et al, 2000). Frequency Several studies have examined the impact of the frequency of walking per week on blood pressure in order to determine what frequency is most effective in terms of blood pressure reduction response. A study by Gettman et al, conducted in 1976, which compared the effect of fast walking between one, three and five days per week on blood pressure response, found that the difference in frequency was no... ... middle of paper ... ...ffect on systolic blood pressure only. Lee et al (2010) found that moderate to high intensity waking was more likely to decrease blood pressure than low intensity walking. This result supports the findings of the study conducted by Quinn in the year 2000. Nemoto et al (2007) compared the effect of continuous walking at moderate intensity (50% of peak aerobic capacity) and interval walking at high intensity (70% of peak aerobic capacity) on reducing blood pressure. They found that blood pressure reduction was greater in the group who walked at high intensity: 9 mmHg for systolic blood pressure and 5 mmHg for diastolic. The results of a study conducted in India by Gosh (2006) to measure the effect of walking intensity (2 Km/30min) for 20 weeks, showed that there was a significant reduction in systolic/diastolic blood pressure by approximately 10 mmHg/4 mmHg.
How does this history of high blood pressure demonstrate the problem description and etiology components of the P.E.R.I.E. process? What different types of studies were used to establish etiology or contributory cause?
This experiment was performed twelve times, on three subjects, over a period of 4-6 weeks. The first subject was a six-year-old boy named Gideon (results are shown in Figs.1-4). His initial blood pressure was 92/53 mmHg; this stayed consistent throughout the entire experiment. The first genre of music that was tested was rock music (Fall Out Boy: My Songs Know What You Did in the Dark). The first time the experiment was performed, his blood pressure was 98/55 mmHg, the second time it was 99/56 mmHg, the third time it was 99/55 mmHg, and the fourth time it was 98/56 mmHg. The second genre of music that was tested was country music (Carrie Underwood ft. Sons of Sylvia: What Can I Say?). During the first trial, his blood pressure was 91/53 mmHg, the second time it was 92/54 mmHg, the third time it was 91/52 mmHg, and the fourth time it was 92/53 mmHg.

Blood pressure is a measurement of the force against the walls of your arteries as your heart pumps blood through your body. Hypertension is another term used to describe high blood pressure. This common condition increases the risk for heart disease and stroke, two leading causes of death for Americans. High blood pressure contributed to more than 362,895 deaths in the United States during 2010. Approximately 67 million persons in the United States have high blood pressure, and only half of those have their condition under control. An estimated 46,000 deaths could be avoided annually if 70% of patients with high blood pressure were treated according to published guidelines (Patel, Datu, Roman, Barton, Ritchey, Wall, Loustalot; 2014).
This article discusses in detail, the various benefits of cardiovascular exercise for overall cardiovascular health.
This force transfers into the arteries and arterioles in other parts of the body as the blood moves away from the heart. Once the intensity drops and the stress on the heart decreases, the pressure in the arteries also reduces due to the less forceful contractions. Therefore, the hypotheses were accepted based on the averages of the data collected during the experiment. However, in order to have more accurate data, a larger sample size would be needed. In addition, using machines to measure heart rate and blood pressure could make the data more accurate than the process that was used in this experiment. Increased accuracy could also have been seen if there were more trials done when taking heart rate and blood pressure during the exercise stages and then averaging those

Vicki is a 42-year-old African American woman who was diagnosed with Hypertension a month ago. She has been married to her high school sweetheart for the past 20 years. She is self-employed and runs a successful insurance agency. Her work requires frequent travel and Vicki often has to eat at fast food restaurants for most of her meals. A poor diet that is high in salt and fat and low in nutrients for the body and stress from her job are contributing factors of Vicki’s diagnosis of hypertension. This paper will discuss the diagnostic testing, Complementary and Alternative Medicine treatments, the prognosis for hypertension, appropriate treatment for Vicki, patient education, and potential barriers to therapy that Vicki may experience.
This study assessed heart rate, blood pressure, and pulse oximeter readings at rest and during exercise. The heart rate (HR), blood pressure (BP), and oximetery measurements provide better insight into the inner workings of the human body. In using the results of the assessment, one can determine the affects that rest and exercise have on the cardiac system.

Walking is easy, free, simple, and one of the best ways to lose weight, become healthier and get more active. Though underrated as a form of exercise, walking is ideal for people of all fitness levels, and ages who want to be more active. Walking regularly has been shown to reduce the risk of chronic illnesses, including Type 2 diabetes, heart disease, asthma, stroke and some types of cancer.
One study reveals that the weight-loss benefits of cardiovascular exercises are already an established medical fact (Hope, Kumanyika, Shults and Holmes 1028). John, therefore, has an ally in strenuous activities. For example, he may do weekend runs for at least thirty minutes non-stop. If not, he may do three runs of ten minutes each per Saturday. The initial run can serve as his gauge for the succeeding runs, whether he needs to increase or decrease the duration. Consistency is crucial. John must make regular weekend runs in order to achieve continuous weight loss. However, this does not mean that he has to run the same distance throughout. Eventually, John may level-up his jogging routine by extending the number of minutes, by increasing the total distance per run, or by shifting to elevating paths instead of simply running on flat
