Walking is one of the oldest means of transport known to mankind as well as a more physical activity undertaken by the majority of people in their lives.
Walking has become an interest field for researchers, where there is evidence to show how walking can help in the prevention and treatment of many chronic diseases, such as cardiovascular disease, diabetes, renal diseases, hypertension, breast cancer, colon cancer, depression, stress and obesity. It has also become a major recommendation of the American College of Sports Medicine (ACSM) and the Center of Disease Control (CDC). It is suggested that brisk walking for 30 minutes, 5 days a week, at 3-4 miles per hour for adults is a form of moderate intensity physical activity which can prove effective as a useful prevention and treatment model (Lee and Buchner, 2008).
Many studies have provided evidence that walking is an effective approach for decreasing blood pressure in both hypertensive and normotensive, and that there is an inverse relation between them (Kelley et al, 2001). A recent systematic review, which involved 27 randomized controlled trials, showed a reduction in either systolic/diastolic blood pressure, or both, in response to a walking programme. This reduction was significantly statistically shown in 9 trials. Of these 9 trials, three studies reported that the decrease was significant for both systolic and diastolic blood pressure, four showed a significant decrease only in systolic blood pressure, while two studies found a significant reduction in diastolic blood pressure. The mean difference between walking groups and control groups was found to range from -5.2 to -11 mmHg for systolic blood pressure, while for diastolic ...

...s too long, participants may be unwilling to follow or complete it. Thus, it has been found that a walking programme which is more than 12 months long is less effective than a 6 month programme, and that the explanation for this is due to a decrease in the participants’ adherence to the programme (see Lee et al, 2010). It seems that the longer the programme, the less likely it is that the individual will keep to it.
It was found (by Lee et al, 2010) that the way in which the time spent walking each day was divided up made no significant difference in terms of reduction of blood pressure response. The study measured the effect of walking on blood pressure by dividing the daily session of walking into three short bouts of 10 minutes; and it was found that this had the same effect on blood pressure as a continuous uninterrupted daily walking session of 30 minutes.

- 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...

- Hypertension Hypertension is also known as high blood pressure about 25% of all adults have high blood pressure, normal blood pressure in an adult is measure is less than 120/80 the top number is known as systolic and the bottom diastolic any reading above this is known as hypertension. If the blood pressure is regularly high this can damage to the blood vessels kidney, heart and other parts of the body which can result in a stroke or heart attack, causes of high blood pressure may be more than one thing for example too much salt in a person’s diet, being overweight, not eating enough fruits and vegetables and other life factors like stress....

A meta-analysis of prospective cohort studies reveals that increased consumption of fruit and vegetables from less than three to more than five servings/day correlates with a 17% reduction in coronary heart disease risk (He, Nowson, Lucas, & MacGregor, 2007). The hypothesis that dietary fibres protect from ischemic heart disease was introduced in 1970s (Trowell, 1972). Since then, a diet rich in fibre has been linked to the CVD risk factors (e.g. obesity, high cholesterol and hypertension) (Van Horn et al., 2008; Truswell, 2002)....

- Blood pressure is defined as the force of the blood against the artery wall. If ones blood pressure is too high or too low it may cause cardiovascular problems in the future. When blood pressure is measured, a cuff is placed on your arm, we will add pressure to this cuff to temporarily stop the blood flow. With a stethoscope we will then listen to your blood flow. By doing this we get two measurements, the first is systolic pressure. Systolic pressure is the reading when the blood is being contracted by the heart, or when the heart contracts, and diastolic pressure, measured when the heart relaxes.... [tags: Blood pressure, ]

- General Studies and research of Cardiology Cardiology is the diagnosis and treatment of human or animal hearts In the focus of Cardiology, the heart has many different anatomical features including ventricles, atria and valves. While plenty is known about the healthy heart, Cardiology usually studies diseased hearts. Because diseases of the heart can lead to many complications and is the leading cause of death, it is important to study these diseases to try and develop new medicine or procedures to prevent heart disease from causing so many complications....

- High Blood Pressure is major health problem affecting the lives of many people. Most people are not aware of the many causes or solutions of high blood pressure. Causes can range from high sodium diets to high amounts of stress. In modern society, many people live a fast paced lifestyle, which puts them in a position to be more exposed to fast foods loaded with large quantities of sodium and stressful situations within their careers. Having high blood pressure means that there is a strong force of blood pushing against the artery walls throughout the circulation of the body.... [tags: DASH, blood, pressure]

- 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 lower edge of the cuff was about 1 inch above the bend of the elbow. The cuff was inflated quickly to about 160mm Hg; next, the valve of the cuff was opened slightly, allowing the pressure to slowly fall. A standard stethoscope was used to determine blood pressure. The measurer then placed the bell of the stethoscope firmly on the brachial artery of the arm being measured. As the pressure falls, the reading when the sound of blood pulsing was first heard was recorded. This was the systolic pressure.... [tags: systolic blood pressures]

Individuals who smoke, assume smokeless tobacco is safer than cigarettes due to the fact nothing is being inhaled through their lungs, however smokeless tobacco, often known as dip, has fiberglass in the tiny pieces. While smoking, you’re damaging your lungs, while ‘dipping,’ you’re damaging your mouth. Almost every school system in the United States do not allow tobacco products on school premises. If a student is caught smoking tobacco, or even have a pack of cigarettes in their pocket they’re sent straight to in school suspension, and receive a court date and a $52.50 fine....

- As blood flows through the body, it exerts stress on blood vessel walls; creating an effect known as blood pressure. Blood pressure is measured by “the force in the arteries when the heart beats (systolic pressure) and when the heart is at rest (diastolic pressure)” (American Heart Association [AHA], 2008, para. 1). An average healthy adult’s blood pressure has a measurement of 120 over 80 or less (AHA, 2008, para. 3). “High blood pressure (also called hypertension) occurs when your blood moves through your arteries at a higher pressure than normal” (AHA, 2006, para....
