Effect Of Exercise On Arterial Bloodstream Pressure

The goal of this test is to research the consequences of different intensity of exercise on heartrate and arterial blood circulation pressure in young healthy human subjects.

Jumping jack exercise can be used in this test by increasing the occurrence of jumping which are 5, 10, 20, 25 and 30 cycles continuously for 5 lessons. The HR and BP were assessed before and following the exercise for the study of hypothesis. Data revealed that there is a rise in HR and BP among the content. Furthermore, with increasing level of exercise, the difference between your values before and after exercise also increased. However, diastolic blood circulation pressure didn't show any significant difference.

The cardiovascular system comprises of the heart and circulatory system. The heart and soul pumps blood to the organs, tissues, and skin cells of our body. Oxygen and nutrients are shipped by the blood to every cell of the body. Alternatively, carbon dioxide and waste materials are removed by the blood vessels. It is important to understand the heart in order to totally comprehend the physiological effects of exercise on the human body. 1

The illustration shows leading surface of an heart, like the coronary arteries and major blood vessels.

The center is a myogenic muscular organ which acts like a pump to continually send blood to your body cells. It gets the shape of the upsided pear. The center is located between your lungs in the middle of our chest. It has a double-layered membrane called a pericardium. The pericardium operates to safeguard the heart and soul. The exterior pericardium coating is fastened by ligaments to your diaphragm and other areas of our body. The internal pericardium level is attached to the heart and soul muscle. There exists a coating of substance separating the two tiers of the membrane. This enables the heart to move as it beats and yet still be attached to our body. 3

In this task, we would like to study the effects of exercise on heartrate and blood circulation pressure. The designed hypothesis is the fact that exercise will cause a rise in heartrate, a rise in systolic blood circulation pressure and a slight decrease or pretty constant diastolic blood pressure.

Heart rate

Heart rate is described by the number of heartbeats per unit time, in minutes. The heart rate of a human being may change depending on need for oxygen. When air dependency boosts, the heartrate increases. When oxygen dependency decreases, heartrate decreases. Heart rate is measured by counting the pulse of the body. 4

Blood pressure

Blood pressure is defined as the push applied on the wall surfaces of the arteries as bloodstream is pumped throughout your body. Pressure is determined by the drive and amount of bloodstream being pumped and also determined by the scale and flexibility of the arteries. Blood pressure is afflicted by many factors like the individual's daily routine, diet, emotional status and good posture. 5

Blood pressure is measured with a device called the sphygmomanometer. It steps the magnitude of pressure necessary to block blood circulation through an artery. Pressure is applied by the sphygmomanometer which cuffs someone's arm. 6

The ideal blood circulation pressure is below 120 over 80 (120/80). The systolic pressure is the number above and the diastolic pressure is the number below. Systolic blood circulation pressure is defined as the blood pressure when the heart is contracting. Specifically, it's the highest arterial pressure during contraction of the still left heart ventricle. Diastolic pressure on the other hand steps the pressure exerted by the heart when the heart is at rest.

The suggest arterial pressure is the common blood pressure of an individual. It could be determined by the following formula:

MAP = DP + 1/3(SP - DP)7

SP = Systolic pressure

DP = Diastolic pressure


From the band of 14 individuals, one person is selected to take measurements of blood circulation pressure and heart rate of the remaining 13 individuals. The 13 things contain 3 males and 10 females, with an average BMI of 19. 49. Firstly, the heart rate and blood pressure of the first individual was measured. Then, 5 cycles of the customized jumping jacks were performed. After the 5 cycles of exercise was performed, the topic was required to sit within an upright position, where blood pressure and heart rate was measured. The subject was also given 3 minutes as relaxing time. After the resting period, the first person carried on with an increment of 5 cycles of the same exercise up until 20 cycles. (i. e. : 5 cycles, 10 cycles, 15 cycles, 20 cycles) This was done with the remaining 12 topics.


Anticipatory period

All subjects were necessary to sleep at least 7 hours prior to the day of the exercise. No caffeine and alcohol diet must be consumed 3 time before the exercise. Content were necessary to eat one banana and one energy pub cracker 3 time prior to the exercise was conducted. Proper sports activities dress was worn by all 13 participants. 5 minutes of relaxing period was presented with to each subject. Subjects were required to sit within an upright position while resting. Hand mobile phones were powered down to avoid interruptions while doing exercise. Laughing and eating are prohibited during exercise for much more accurate readings. Last but not least, all content were in well being during exercise and aren't under influence of any drugs.

Exercise period

During the exercise, activities such as laughing, communicating and vigorous movements are not allowed. All prospects must keep their hands straight while doing jumping jacks, and must squat completely throughout the span of the exercise. The combat of the metronome was arranged at 84 beats each and every minute.

Resting period

All subjects were not allowed to take in any beverages no other moves were allowed except the exercise brought up. A resting amount of 3 minutes was given to each subject matter. The identical stopwatch was used to measure the resting period.

Heart rate and blood pressure measurement

Only 1 person was assigned to gauge the blood circulation pressure and heartrate of the 13 members. Initial heartrate and blood circulation pressure was performed 1 minute before the exercise was conducted. After conducting the exercise, heartrate and blood circulation pressure was assessed immediately. The heartrate was measured first accompanied by blood circulation pressure. All themes were necessary to sit within an upright position while getting their heart rate measured. The exact same sphygmomanometer and stethoscope were used to gauge the subject's blood pressure.

Methods to assess heart rate and bloodstream pressure

Heart rate

Firstly, the palm side of the subject was changed facing up. The index finger was placed on the wrist of the topic, approximately 1 inches below the bottom of the subject's hand. The index finger is pressed down in the grove between your midsection tendons and outside the house bone. A throbbing pulse should be noticed. The number of beats was counted for 30 a few moments, and multiplied by 2. This will give a heartrate of 1 1 minute. 8

Blood pressure

The sphygmomanometer was inflated to just a little above 180mm Hg. This collapses the major arteries of the arm. Air is released by turning air valve. The pressure should drop. If the first throbbing audio was center, the systolic blood pressure was registered. The sound observed following the first throbbing audio is the audio of blood flowing through the artery of the arm. This implies the systolic blood circulation pressure is greater than the pressure in the blood pressure cuff. Air valve is still released until no sound is been told. When no more sound is observed, the diastolic blood circulation pressure is recorded. 10

Exercise description

Firstly, both ft are put along, with without doubt on both sides. Candidates must jump to move both feet apart while both of your hands are raised 90 diplomas from your body. They are required to jump again to move feet jointly and bring both hands together over the head by clapping. The exercise topics then return to the next position, where both feet are aside and both of your hands are 90 levels from your body. Next, individuals then go back to the original position. Last but not least, the candidate is required to squat once and then return to position one. Only after executing each one of these steps is one cycle considered.


Banana, energy bar cracker, metronome and stopwatch were ready before the test.

Type of exercise

The exercise is a revised version of jumping jack. All content were necessary to complete the exercise based on the speed establish by the metronome.

Interpretation of results

Statistical test

The one-way ANOVA turkey test was used to determine whether there were any difference in systolic blood circulation pressure, diastolic blood pressure, heart rate and imply arterial pressure between your amount of cycles of exercise.

Null hypothesis: There is no difference in heart rate, systolic blood circulation pressure, diastolic blood circulation pressure and imply arterial pressure before and after exercise.

Alternate hypothesis: There's a difference in heart rate, systolic blood pressure, diastolic blood pressure and mean arterial pressure before and after exercise. (Heart rate, systolic blood pressure, and suggest arterial pressure boosts, diastolic blood circulation pressure remains the same or lowers slightly)

Result interpretation

From the results for table 2, it can be seen that the pace of heart rate increases when the amount of cycles of exercise boosts. Statistically, from the one-way ANOVA turkey test, the calculated p-value for heart rate was less than 0. 05. When the calculated p-value was minimal than 0. 05, this implies that there is a significant difference in heartrate between the range of cycles of exercise. From the graph obtained in number 1, it could be seen that the heartrate increases progressively when the amount of cycles of exercise raises.

From the results for stand 3, the result is comparable to the consequence of stand 2. Systolic blood circulation pressure increases when the amount of cycles of exercise increases. Through the one-way ANOVA turkey test, the determined p-value for heartrate was also reduced than 0. 05. This implies a significant difference in heartrate between the numbers of cycles of exercise. From shape 1, it can be seen that the heartrate increases continuously when the amount of cycles of exercise increases.

From the results for stand 4, the diastolic blood pressure decreases when the amount of cycles of exercise increases. In the one-way ANOVA turkey test, the computed p-value for diastolic blood circulation pressure was also less than 0. 05. Therefore a significant difference in diastolic blood pressure between the amounts of cycles of exercise. From the figure, it can be deduced that diastolic blood pressure decreases, however only slightly when the number of cycles of exercise rises.

From the results for stand 5, the mean arterial blood circulation pressure seems similar throughout the cycles of exercise. When calculating the p-value using one-way ANOVA turkey test, the p-value was higher than 0. 05. This implies there is no factor in the mean arterial blood pressure between the amounts of cycles of exercise. In the figure, it can be deduced that the mean arterial pressure doesn't go through any change as the amount of cycles of exercise increases.


Effects of Aerobic Exercise on Heart and soul Rate

The heart rate for a person is 60 to 100 beats per minute. Heart rate per minute will increase depending on frequency of activities the individual perform. During exercise, muscles undergo aerobic respiration which requires constant oxygen supply. This is because the amount of carbon dioxide in the bloodstream increases due to the growing cell respiration of the muscles. Thus, the lack of oxygen leads to a huge hurry of oxygen absorption through the lungs. An impulse is then sent to the sinoatrial (SA) node which causes the center to defeat faster. The increased air intake activates the oxidation of lactic acid into carbon dioxide to be carried away. Because of this, the muscles will produce the most amount of energy per mole aerobically. 10

Oxygen, carbon dioxide and hydrogen ions (H+) are discovered by chemoreceptors which are located at the medulla oblongata and parts of the peripheral stressed system. When exercising, H+ increases because of the excess carbon dioxide. A growth in H+ awareness triggers the chemoreceptors which in turn send impulses to the inspiratory centre to increase deep breathing rate. Hence, heartrate increases. On the other hand, having less oxygen also causes a rise in breathing rate. The peripheral chemoreceptors are turned on when large oxygen is reduced. Signals are then delivered to the inspiratory centre to improve the breathing rate, and so heart rate. 11

Besides, lactic acidity which dissociates into lactate and H+ during anaerobic respiration when exercising also ends in a growth is H+ amount. This in turn increases the heart rate by the same mechanism reviewed above. 12

Heart rate may also be altered by autonomic nervous system. Excitement of the sympathetic anxious system causes an increase in heartrate as well as other factors such as stroke level and systemic vasoconstriction. 13 The stimulated sympathetic stressed system also acts to release sugar from the liver organ for energy. During exercise, heart rate rises rapidly due to the activation of sympathetic stressed system. 14

Apart from that, the stimulated sympathetic nerves also release catecholamines such as epinephrine and norepinephrine. They work to cause the heart to conquer faster by increasing the depolarization of sinus node. This increase of heart rate is recognized as tachycardia. 15 Furthermore, the contractility of the heart and soul muscles will can also increase through binding of catecholamines with alpha-adrenegic receptors on the simple muscles. 16

The parasympathetic stressed system opposes the sympathetic nervous system which slows the heartrate especially when exercise such as exercise has ended. This is because of the release of hormone acetylcholine which hyperpolarizes the membrane and inhibits heartrate. The slowing of heartrate is known as bradycardia. 17 When relaxing after intense exercise, both autonomic anxious systems still work constantly to send impulses to the SA node. However, inhibitory is dominance over excitatory. As a result, vagal firmness is said to be exhibited by the heart and soul. In addition, if the vagal nerves are not innervating the heart, the heart rate will be slower than it might be. 16, 18

Other than that, atrial reflex or known as Bainbridge reflex is set up during exercise. This reflex consists of in increasing the venous return and blood congestion in the atria. By stimulating the SA node and baroreceptor in the atria, the atrial wall space are stretched which increase to the pressure as well as heartrate. Because of this, the reflex action causes a rise in sympathetic activation of the center which in turn increases the heartrate. 19

Another factor which contributes to an increase in heart rate is your body temperature. Metabolic rate raises during exercise. This causes the body heat to go up when the metabolism in the body release energy as warmth. 15Consequently, sympathetic outcome in the centre will increase because of the impulses dispatched by the thermoreceptors to the somatosensory cortex and thus heart rate increase. 18

Effect of Aerobic Exercise on Systolic Blood Pressure

In this experiment, 13 themes were necessary to perform a changed version of jumping jacks at different power levels. The exercise was performed in cycles where increased cycles of jumping jacks will increase the depth of the exercise.

The mean blood pressure of an individual depends on the quantity of blood circulation from the center throughout your body and the web resistance of blood flow in the arteries of the body. Blood circulation pressure is determined via the following formula:

BP = CO x PVR where,

BP= blood vessels pressure

CO= Cardiac Output

PVR=Peripheral vascular resistance

During exercise, doing exercises muscles produces more carbon dioxide, thus this escalates the blood partial pressure of skin tightening and (PCO2) in our body. As PCO2 raises, the necessity of oxygen consumption into the human body increases. Oxygen usage increases when PO2 decreases. Since oxygen is taken by the blood vessels in the form of oxyhaemoglobin, therefore, your body would need to pump in more oxygen to accommodate for the lack of oxygen. 20

From the formula BP = CO x PVR, increase in cardiac output rises blood pressure. As systolic blood pressure is the pressure when the heart and soul is contracting, which means systolic blood circulation pressure should increase with increasing exercise.

During exercise, the systolic blood pressure of each experiment subject sometimes appears to be increasing throughout each cycles of the exercise. In the table, it could be seen that the mean systolic blood pressure increased from 106. 5 at relaxing blood circulation pressure up to 135. 5 when the exercise was conducted at 20 cycles. Thus, the test supports the declare that exercise raises systolic blood pressure.

Effect of aerobic exercise on diastolic blood pressure

Diastolic blood pressure is the blood pressure when the heart and soul is relaxing. It's the blood pressure of your artery surfaces between center beats. Diastolic blood pressure is affected mainly by blood volume, stroke level and heart rate. 21

Stroke size (SV) is the difference between end-diastolic volume level (EDV) and end-systolic volume level (ESV). It really is related by the next equation:

SV = EDV - ESV22

EDV is the quantity of blood prior to the heart agreements and ESV is the quantity of blood kept in the heart after it deals. Therefore, SV is the net volume of blood pumped out by the center in 1 heart beat. During exercise, air consumption increases, therefore the amount of bloodstream had a need to pump throughout the body also heightens, therefore stroke size increases during exercise.

During exercise, the temps of the body increases. When this happens, the body undergoes negative opinions by dilating the arteries in the torso. Vasodilation happens to increase the blood circulation to around the cells and to take away warmth from the body. Therefore, during exercise, cardiac outcome raises whereas peripheral vascular resistance decreases anticipated to vasodilation. Thus, this triggers the diastolic blood circulation pressure to remain rather regular throughout, or lower slightly.

From the test, the diastolic blood circulation pressure decreases slightly during the period of exercise. As exercise was conducted, vasodilation could clarify the cutting down of diastolic blood circulation pressure throughout the exercise.

Effect of aerobic exercise on Mean Arterial Pressure (MAP)

MAP is the common pressure of blood vessels exerted on the wall space of the arteries through the whole cardiac pattern. MAP is the product of cardiac outcome and total peripheral resistance. During exercise, cardiac outcome increases to meet the metabolic needs of skeletal muscles. 23Total peripheral amount of resistance on the other palm decreases credited to vasodilation of blood vessels. However, total resistance of systemic flow is kept constant anticipated to constriction of arterioles in visceral organs such as the kidneys and gastrointestinal system. Therefore, MAP boosts in exercise due to the large increase in cardiac productivity. 7

The formula to derive mean arterial pressure is as follow:

MAP = DBP + 1/3 (SBP-DBP)7

Throughout the exercise, systolic blood pressure increases drastically whereas diastolic blood pressure remains fairly constant or decreases just a bit. Therefore, this elevates suggest arterial pressure. From your test, the mean arterial pressure is fairly regular throughout the test. This may be because of the inaccuracy of the measured diastolic blood circulation pressure. Besides that, the exercise may be switched into a stress test, where topics must perform exercise to their limitations. A stress test could plainly show mean arterial pressure difference because cardiac end result would be at it's maximum.

From the results obtained, it could be seen that the mean arterial pressure is rather frequent throughout the test. This could be due to the inaccuracy of the measured diastolic blood circulation pressure. Besides that, the stable reduction in diastolic blood circulation pressure may possibly also override the increase in systolic blood circulation pressure, thus causing the consequence of mean arterial pressure to remain frequent throughout the experiment.


Due to the restrictions of the experiment, the obtained results were not that regular and accurate in comparison with the theoretical results.

First of most, the test size is quite too small and insufficient for statistical interpretation as it involves just 13 members in the test.

Gender factor impacts the obtained results too. This is due to the imbalance volume of females and males in the sample which is 2 males and 11 females. As different genders have different metabolism rate, this plays a part in unwanted mistakes in the results. 10

Other than that, the relaxing period in between each group of experiment was insufficient anticipated to time constrain. The heart rate and blood pressure were not allowed to return to the relaxing level prior to the consequent test is carried out.

In addition, scheduled to two different people in calculating the heart rate and blood pressure, it leads to variations in willpower of the final readings of the results. There could also be misunderstandings of auditory and aesthetic cues specially when reading for the diastolic pressure.

Further Studies

In order to improve the studies, a larger sample size can be used to increase reliability of the results. When a larger test size is used, more evaluations can be made between the dissimilarities of genders, age group, BMI, as well as the regularity of exercise.

Besides, enough time of the resting period can be improved to be much longer. This is to ensure that the heartrate and blood circulation pressure have delivered to the relaxing level before the next group of experiment starts in order to lessen the inconsistency of the results.


From the test, the results show that there is a rise in heartrate and systolic blood pressure. However, diastolic heart rate showed a cut down. Calculated indicate arterial pressure(MAP) remained continuous throughout different exercise power. However, this may be due to many reasons discussed by above.
