According to Wikipedia, (BP) or blood pressure is the “resulting pressure as blood circulates upon the walls of blood vessels”; however pulse is the “tactile palpation of the heartbeat by trained fingertips”. In adults, a blood pressure of 120/80mmHg would be considered healthy. Ventricular contraction, also known as systolic pressure is the pressure exerted on blood vessel walls during a ventricular contraction. Diastolic pressure is the minimum arterial pressure reached during vessel relaxation. (Wikipedia.2015)
The mean arterial pressure is the pressure that pushes the blood through various tissues ( Mitchell & Marie E, 2013). Stroke volume, somewhat similar to cardiac output, is the amount of blood pushed out by one ventricle per single beat (Chandran et al, 2012). It is calculated by taking the variance of the end diastolic volume to that of the end systolic volume (Chandran et al, 2012). The end diastolic volume is the volume of blood that gathers in a ventricle during diastole (“relaxation”), while the end systolic volume is the amount of blood lingering in a ventricle after the ventricle has contracted (Chandran et al, 2012). MAP is the product of the cardiac output and the resistance (Chandran et al, 2012). Resistance is the “opposition to flow and is a measure of the amount of friction blood encounters as it passes through the vessels” (Susan Mitchell& Marieb E, 2013). Cardiac output (CO), alternatively, is defined as the volume of blood boosted by each per minute (Marieb & Susan Mitche...

...g, caused by fatigue in that specific arm. Having subject perform the baseline test while lying down could enhance qualitative results in the experiment. Sitting down limited proper blood flow to bottom of the leg and could have cause reading to be higher that it should have been.
This experiment clearly painted how heart rate and pulse rate can be affected by rigorous exercises, posture and cardiovascular fitness.

- In the United States about 73 million adults ages 20 and over have hypertension, which is one in every three adults (Frost & Topp, 2006; Pirotte et al., 2012; Shaw & Bosworth, 2011). That number increases even more when looking at the worldwide population with an estimated 985 million people with hypertension, and a projection for further increase to 1.56 billion by 2025 (Kim et al., 2010; Park et al., 2012). Hypertension and smoking is a leading risk factor for other cardiovascular diseases such as stroke and myocardial infarctions; therefore taking control of high blood pressure can mean life or death for adults with hypertension....

- Hypertension in the low income African American community have increased (American Heart Association, 2015). This disease is plaguing this community. An appropriate goal for health promotion in the low income African American community is to decrease one risk of hypertension. By doing so, ten people in this community will ask be asked to volunteer to participate in this goal project. These participant participants will decrease his or her current weight by at least ten pounds by September 1st, 2015.... [tags: Obesity, Hypertension, Blood pressure, Weight loss]

- The Importance of Exercise Imagine one day lying in your death bed with a chronic disease just because you ignored the importance of exercise. This may sound dramatic but this can really happen to anyone if they don’t get an adequate amount of exercise in their lives. One major problem I see all around me almost every day of my life is the common lack of exercise. Including myself, I don’t think most people understand the importance of exercising to stay healthy in our daily lives. This is a very significant issue in the United States today because it is not appreciated enough for what it does for us.... [tags: healthy habits]

- 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....

- In our family tradition, someone 's feelings and bodily functions are often blamed on weather. When my grandmother 's blood pressure begins to change, she will claim it is a result of shifting atmospheric conditions; when I feel down, she links it with my low blood pressure and consequently blames my feelings on weather as well. I 'm inclined to believe my mood isn 't linked with blood pressure or with what kinds of events are taking place in the sky, since I can feel low even when my blood pressure is relatively high and the weather is pleasant, but her assertions make me wonder if a correlation really does exist between these phenomena....

- Hypertension (High Blood Pressure) is an illness that millions of people of all sorts are affected by. Moreover, although stress and emotional tension can temporarily increase blood pressure; but it won’t be considered as high blood pressure. Hypertension usually is there with no symptoms. It may happen and remain unseen for many years. People, until told by a medical physician generally overlook high blood pressure. People are not aware of how hypertension affects the body, how it is measured, what the symptoms are of high blood pressure, and what people/ethnic groups are affected by hypertension more than another....

- Hypertension (High-Blood Pressure) Ever since my dad reached his mid-thirties he has had to deal with his high-blood pressure. Not only does my dad have high-blood pressure, but so does my dad’s two brothers and mother. According to the National Heart, Lung, and Blood Institute, “Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps blood. High blood pressure, sometimes called hypertension, happens when this force is too high.” Blood pressure is measured with the use of a gauge, stethoscope, and a blood pressure cuff which is the thing that wraps tight around your arm like a python....

- Hypertension, or high blood pressure, is a common disease affecting about 70 million Americans but only about half of those affected Americans have their blood pressure under control. 1 in 3 adults are in prehypertension, which means they are in the blood pressure range that is in danger of obtaining hypertension but the numbers are not quite high enough to diagnose them with the disease. Hypertension diagnosed when a person has tension, or high pressure, in their arteries. The more blood that is pumped into a person’s arteries and the narrower the arteries become, the higher the blood pressure.... [tags: Blood pressure, Hypertension]

- Disease Pathology Hypertension or high blood pressure has been one of those chronic diseases that have plagued the United States. Approximately, 73.6 million adults suffer from hypertension. It is estimated that 77.6% of patients are aware of their hypertension and is being treated. However, only 44% of patients have their blood pressure under control. Hypertension takes years to develop. Uncontrolled high blood pressure can increase the risk of serious health problems such as cerebrovascular, cardiovascular, and renal disease by the age of 50....
