Exercise is one of the best ways of getting a healthy mind and a healthy body. But as we all know there is a major role of this exercise in the circulation of our blood, and also to our circulatory system. There are some changes that take place with regards to the circulation of the blood in our body before the exercise and after doing it. Blood pressure is an important measure of the state of the heart and blood vessels. It is defined as the force the blood exerts against the blood vessel walls. The pumping action of the heart generates a blood flow through the vessels.
When resistance from vessel walls, blood pressure results, meets this flow. Blood pressure is usually read as the systolic pressure over the diastolic pressure. Systolic pressure is the pressure in the blood vessels when the ventricles of the heart contract, while diastolic pressure is when the ventricles are relaxed. The two pressures are obtained by creating a pressure great enough to stop the flow of blood through the artery that is being tested. This can be detected by the ability to hear blood squirting thought the vessel each time the heart contracts.
The first heart sound that is detected through the stethoscope is the systolic. Heart sounds will be heard until the pressure is low enough on the arm that diastolic pressure has been reached. Caution must be used when measuring blood pressure over several hurried measurements. It is preferable to take one measurement carefully, repeating for uncertainty and distraction. The measurements will also vary according to the time of day, meals, smoking, anxiety, temperature and season of the year. Treatment of high or low blood pressure is frequently encountered in the field of medicine.
It is important to remember that the treatment should not be based primarily on one measurement, but on the patterns of blood pressure change during a period of observation. A normal heart receives oxygenated blood, denoted in red (right), entering via the left and right pulmonary veins. Upon contraction, blood is forced out of the left ventricle through the aortic valve and out to the rest of the body. Blood that does not contain oxygen, seen in blue above, is forced out of the right ventricle through the pulmonic valve and into the lungs.
A pulse is felt because of the flaring of the aorta as the ventricle of the heart flares. Obtaining a pulse rate is important in determining how hard the heart is working and if a blood flow to a specific limb or body region is normal. The purpose of this experiment was to allow students to determine resting heart rate (pulse) in beats per minute and to demonstrate the effects of moderate exercise upon the heart rate Hypothesis: 1. The effect of exercise to the heart rate 2. The effect of exercise to the blood pressure 3. The significant difference between the heart rate to the blood pressure
Material and Methods Timer or Watch Stethoscope Adult size blood pressure cuff with sphygmomanometer The twenty-two respondents, age 20 to 50 is taken one by one with their blood pressure and heart rate. The first procedure is by taking it in a sitting position. Heart rate s was taken either from the radial artery (located on the palm side of their wrist) or from the carotoid artery (located either side of the wind pipe in the neck) by placing the two fingers gently on the artery and counting the beats for one minute. After that the second position is lying on their back.
Taking again their heart rate and blood pressure. The third stage is running for three minutes. The blood pressure was taken with Stethoscopes and adult size blood pressure cuffs with sphygmomanometers. The cuff was properly placed on their upper arm and the bell of the stethoscope placed over the brachial artery located in the inner area of their bent elbow. The mean arterial pressure is calculated from the BP reading from the data that is being collected along with their age and the gender. Results The raw data that is being collected is the age of the respondent and the Heart rate and Blood pressure.
The result of the data shows that there is an increase in the heart rate and blood pressure of the respondents after conducting a running. The data shows that there is also an increase in the systolic and diastolic of blood pressure. The mean for heart rate in sitting position is 83. 18 while on lying heart rate is 82. 14 and the running is 149. 32. This means that there is an increase in the heart rate of running. The standard deviation of sitting has 8. 20 while the lying has also 8. 20. The value for running has a standard deviation of 22.
69, which means that it is a more clustered data when the respondents are in the sitting position and lying position. The result of running in their standard deviation are farther apart which tell us that there is an increase in the mean of the blood pressure in the systolic and diastolic. Discussion Getting the pulse measurement before and after an exercise gives us different advantages like; it provides clues about the function and health of the heart. It also evaluates certain symptoms, such as an irregular or rapid heartbeat (palpitations), dizziness, fainting, chest pain, or shortness of breath.
It assess circulation in an injured extremity or in an extremity with a blocked blood vessel. Monitor medical conditions or the use of medications that slow your heart rate. If you are taking certain medications that can slow the heart rate, such as digoxin or beta-blockers (like propranolol or atenolol), your health professional may want you to check your pulse rate periodically. And check your general health and physical fitness. Measuring your pulse rate at rest, during exercise, or immediately after vigorous exercise can give you important information about your overall physical condition.
Conclusion The result of these experiment indicates that there is and effect when a person is conduction an exercise. There is a significant effect on the heart rate and blood pressure especially the supply of oxygen in our body. There is also a difference when it comes to their heart rate and blood pressure although both of them increase in the data. The heart rate focus on the rate of blood flowing from the veins and arteries while the blood pressure takes the supply of the carbon dioxide and the oxygen in our body which carry it in the different parts of the body.
