Exercise And Blood Pressure

Blood pressure in our blood vessels is monitored by the baroreceptors. These receptors send messages to the cardio regulatory center of the medulla oblongata to regulate our blood pressure every minute. In order for blood to be delivered to all organs and tissues, our cardiovascular system must always maintain adequate blood pressure. If the blood pressure drops too low, these organs will not receive an adequate of nourishing blood. Also if the pressure goes too high, the walls of the arteries will stretch and increased activity within the baroreceptor, information will then be sent through the nerves to the cardio regulatory center within the medulla which will responds by initiating the mechanisms that decrease the blood pressure to a normal

Using class data, compare blood pressure, resting heart rate, and your heart rate after exercising between: A) Males/females. Account for any difference. When comparing blood pressure between males and females, males show to generally have a lower normal blood pressure, around high 90/60-70, while females have a higher normal blood pressure, around 120/50-90. Finally, male heart rates stay at low 90s to low 100s while the heart rates of females vary greatly from low 70s to low 100s. In terms of resting heart rate, females and males generally range from about low 40s to high 90s all together.

Cardiac hypertrophy is the enlargement, or thickening, of the heart muscle. After lots of strenuous exercise the heart muscle will increase. If a person does exercise, a thirty minute jog every day, for six months there will be an obvious increase in many other factors but the heart muscles will have grown in size. These changes are reversible when you discontinue aerobic training.

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.).

High blood pressure causes vary from person to person. Some of the main causes of high blood pressure are genetics, diet, family history, weight, and use of too much salt. Genetics and family history of high blood pressure go hand in hand. Since family members share lifestyles and genes, that can influence their risk for this disease. Some characteristics that are out of your control that can affect the risk for high blood pressure include, age, race, or ethnicity. Although African Americans develop high blood pressure more often than Whites, Hispanics, Asians, Pacific Islanders, American Indians, and Alaska Natives, the lifestyle one lives can

Males, on average, increased their mean arterial pressure by 12.835 units. In contrast, females increased their mean arterial pressure by 2.25 units; however, there was one girl whose mean arterial pressure dropped after exercising instead of increasing. Both males and females all recovered from the exercise within the four minutes given to recover.

During my research, I personally have found that blood pressure levels often equate with low birth weight, body mass, maternal age, racial factors, childhood obesity, insulin levels, an elevated blood pressure during childhood, and a positive family history. In fact, children from hypertensive families generally tend to have higher blood pressure levels than kids from normotensive families. Besides, there is also a greater association in blood pressure levels between fathers and their children.

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

Is a condition where your blood pressure is higher than normal. Frequent exercise can help reduce it. The body needs a set amount of blood when resting preferably around 5 litres per minute when the amount of blood ejected from the heart increases. Regular exercise of cardio vascular disease of hypertension because the heart is more efficient of pumping blood around the body reducing high blood pressure.

The cardiovascular system also known as the circulatory system is the key system of the horse’s body. When getting a horse fit this system needs to be developed in order to increase the horse’s capacity to draw in oxygen, transport oxygen to the muscles for energy, remove waste products and make the muscles; in this case, cardiac muscle of the heart, become more durable and strong.

Lastly, blood pressure is associated with ones diet and lifestyle. It is amazing when one’s diet consist of a high intake of salt they will shows signs of hypertension. Studies have shown that people who did not use salt shown no signs of hypertension. Monitoring the intake of salt will improve blood pressure readings drastically although; it is not the only contributor to high blood pressure. Increasing activity levels has also been known the lower blood pressure readings.

The speed and distance of the run affects your heart rate reading, and how far you should run and be healthy about it (Heather Topham Wood 2015). To find out what your heart rate max should be for men she did 220 minus your age, and for women she subtract 88% of your age from 206. For instance, she said a 40- year- old man will have a maximum heart rate of 180, and a 40- year- old woman will have a maximum heart rate of 171. If you are new to exercise, she says, not to start running at 70 percent of higher of your maximum heart rate immediately. Long intervals of three to five minutes should be run at 95 percent of your max heart rate with short rest periods in- between. Short intervals of no more than 90 seconds can be ran at 100 percent of your max heart rate and should have long rest sessions (Topham Wood, 2015).

The ancient Greeks believed that the human heart pumped an endless supply of “pneuma”, or life energy. Galen, a Greek physician, believed that the “pneuma” and blood flowed from the heart like a fountain. He believed that there was an endless supply of this precious life source. It was not until 1616 that William Harvey determined that Galen was not entirely correct. Due to the practice of bloodletting during Harvey’s time, his belief that blood is in fact finite was not warmly welcomed. (O’Brien)
