Systolic Blood Pressure Essay

The effect of exercise/physical activity on pulse, blood pressure, and respiration rate was tested on biology students. The results of the experiment showed that each of these parameters is affected after engaging in 2 minutes of physical activity. We found that average pulse, mean arterial pressure, and respiratory rate were all higher in males than in females. But, it was also found that women have a longer time to recovery for all these parameters. The reasons for higher pulse, MAP and blood pressure, and respiratory rate could be

Effect of Exercise on Arterial Pressure and Vascular Resistance Abbie DeBerg Ms. Brantley May 30, 2012

Individuals who suffer from heart conditions, particularly adult and aged athletes are those who have had previously suffered from high blood pressure, experienced a heart attack or any other heart problems. Prescribed exercises for individuals within this group demonstrates low risk during participation and considerable health benefits. Health benefits through exercise reduces blood pressure levels, however in order to gain full benefits exercise must be linked with a balanced diet (low fat and low salt intake)

The purpose of this experiment was to test the correlation of heart recovery rates post-exercise in both athletes and non-athletes and determine which group had the faster recovery rate. This was accomplished by selecting six non-athletes and six athletes to run one lap around the Fresno Pacific track for two days. Each participant’s resting heart rate was taken before running the lap and instantly after running the lap as well. Upon completion of the lap their heart rate was measured in thirty second intervals and it was noted how long it took to get back down to each initial resting heart rate again. Due to the athletes training it was hypothesized that they would have the faster recovery rate because they’d be more conditioned

My systolic blood pressure number was 136 and my diastolic blood pressure number was 87. I measured my mom’s blood pressure and her systolic number was 125 and her diastolic number was 85. When ones heart beats in contracts and forces blood through their arteries throughout the whole body. The force required to do this induces pressure on the arteries also known as systolic blood pressure. For ones systolic blood pressure level to be considered optimal it would have to less than 120, to be normal it would have to be less than 130 and to be considered in the high normal range the number would have to fall between 130-139. If ones systolic blood pressure level falls between 140-159 they are in hypertension stage 1, if it falls between 160-179

The purpose of this experiment was to compare the differences between the cardiovascular variables based on people who exercise on a regular basis as well as those who do not with the crucial end result to see how the effects of exercise can benefit cardiovascular health.

Figure 1 shows that the systolic and diastolic pressure while the subject was sitting down, 119/64, is lower than that of the other body positions and exercise. Standing showed the second lowest systolic and diastolic pressure, 121/83. Lying down showed a slightly higher blood pressure of 123/84. The highest blood pressure, 133/94, was measured when the subject had just completed some physical activity. Figure 2 and 3 display, respectively, the difference between heart contractions at rest and after exercise, as illustrated by the greater number of contractions following exercise in the same amount of time compared to resting conditions. In addition to displaying the interval lengths for three sequential beats from Figures 2 and 3, Table 1 also includes the heart rate for before and post exercise, 102 bpm and 132 bpm, respectively. Figure 4 shows similar

Convenience sampling was used to recruit patients with reported uncontrolled BP from a Veterans Affairs Medical Center clinic located in Brooklyn and Manhattan (July 2006 to March 2009).

This report focus on the cardiovascular system to obtain measurement, understand and compare the differences of blood pressure, heart rate, pulse pressure, systolic pressure, diastolic pressure under normal conditions and when exercising.

Heart rate is expected to increase during exercise. The reason for this is that the muscles in the body are demanding more blood and, essentially, the heart must work harder in order to provide for the muscles’ needs. Athletes, who are more adapted to exercising environments have a lower maximum heart rate than individuals who do not exercise as frequently. In a study done between two groups of individuals – one containing only athletes and the other containing individuals who had performed any type of exercise in the previous 6 months – results showed that athletes had a lower heart rate when they performed exercise than non-athletes (Martinelli 2005). The reason that athletes have a lower maximum heart rate is because the heart can pump blood to the rest of the body more efficiently – in larger amounts – than it would in a non-athlete.

Results:Table 1 shows that the subjects mean bpm was highest after exercise (start of recording) at 88.20 BPM and lowest while sitting and breathing regularly at 60.97 BPM. The range of BPM was also the largest after exercise (start of recording) at 74.07-135.14 BPM. Table 2

The heart was more likely to have quicker recovery time when the cardiovascular tissue was better equipped to deal with the strain of the exercise and better conditioned. The weakness with this study is there are too many variables that have been put into play with this experiment. Between the type of exercise, the intervals in which the exercises were to be done, the duration of the experiment. The amount of people within the experiment, as well as their age and family history could have played a large role in this experiment. These variables, as well as other variables that develop more questions could quite possibly be condensed and more isolated in future

As the intensity of exercise increased, so did the rates of the heart and breathing. After a small period of rest, the heart rate and breathing rate both decreased to a point close to their resting rate. This proved the stated hypothesis. First, the hearts average resting rate was recorded to be 76 bpm. The heart is therefore transporting oxygen and removing carbon dioxide at a reasonably steady rate via the blood. During the low intensity exercise (Slow 20) the heart rate increases to 107 bpm, which further increases to 130bpm at a higher intensity level (Fast 20). The heart therefore needs to beat faster to increase the speed at which oxygen is carried to the cells and the rate at which carbon dioxide is taken away by the blood.

I predict that during exercise the heart and respiratory rate (RR) will increase depending on the intensity of exercise and the resting rates will be restored soon after exercise has stopped. I believe that the changes are caused by the increased need for oxygen and energy in muscles as they have to contract faster during exercise. When the exercise is finished the heart and ventilation rates will gradually decrease back to the resting rates as the muscles’ need for oxygen and energy will be smaller than during exercise.

Hypertension is defined a consistent elevation of the systolic blood pressure above 140mmHg, a diastolic pressure above 90mmHg or a report of taking antihypertensive medication. Early diagnosis and effective management of hypertension is essential because it is a major modifiable risk factor to cerebrovascular, cardiac, vascular, and renal diseases. The higher the blood pressure, the greater the risk for heart attack, heart failure, stroke, and kidney disease.
