The systolic blood pressure changes significantly due to the lactic acid interacting with the ATP withing the bloodstream. During light exercises, such as walking or low weight wieghtlifting, the change is minimal. However, One moderate to high exercise is engaged, the change becomes rapid, increasing at a rate of approximately 5% per minute. It eventually plataues around 25% and then drops quite severly once exercise has ceased.
The Diastolic blood pressure however, is almost the complete opposite. There is generally no change within pressure throughout exercise, except when V02 max is reached, initiating a small increase in pressure due to an increase in heart rate.
Hope this Helps!

When Increasing end-diastolic or end-systolic volume will increase stroke volume.?
Increasing end-diastolic volume (EDV) enhances stroke volume due to the Frank-Starling mechanism, where greater ventricular filling leads to stronger contractions. Higher end-systolic volume (ESV) can also increase stroke volume when it results from reduced afterload or increased contractility, allowing the heart to eject more blood with each beat. Thus, both EDV and ESV can influence stroke volume, primarily through changes in the heart's filling and pumping efficiency.
What does air pressure changes with changes?
air mass
Which receptor in sensitive to changes in pressure?
The mechanoreceptor is the receptor sensitive to changes in pressure. It is responsible for detecting mechanical stimuli such as touch, pressure, and vibration and relaying this information to the brain.
Receptors that can respond to changes in pressure?
Mechanoreceptors are sensory receptors that respond to mechanical forces such as pressure. Specialized types of mechanoreceptors include baroreceptors that detect changes in blood pressure and tactile receptors in the skin that respond to touch and pressure. These receptors help the body in detecting and responding to changes in pressure.
What provides the ultimate driving source for wind?
changes in air pressure cause wind, but the sun is the major factor in changes to air pressure.
How do you a treat a person who has high systolic and low diastolic readings when having there blood pressure taken?
A person with high systolic and low diastolic blood pressure readings may be experiencing isolated systolic hypertension, which can be common in older adults. Treatment typically involves lifestyle changes such as a heart-healthy diet, regular exercise, and weight management. If necessary, medications may be prescribed to help manage blood pressure levels. It's important for the individual to consult a healthcare professional for a tailored treatment plan.
Is 119 over 90 healthy for 52 yo female?
A blood pressure reading of 119 over 90 indicates a systolic pressure of 119 mmHg, which is considered normal, but a diastolic pressure of 90 mmHg falls into the category of stage 1 hypertension. For a 52-year-old female, this reading suggests that while the systolic pressure is healthy, the diastolic pressure may require monitoring or lifestyle changes to prevent potential health issues. It's advisable to consult a healthcare professional for personalized assessment and recommendations.
What is the diastolic reading of a blood pressure?
Diastolic refers to the moment when the heart muscle is relaxed between contractions. Diastolic blood pressure is the pressure at that moment - the lower of the two blood pressure numbers. (e.g. if the blood pressure is 120/80, the diastolic pressure is 80.) it is the bottom number of a blood pressure reading. it measures the force of blood in the chambers of the heart: the atria and ventricles.
Does blood pressure rise when there is exertion?
Your circulatory system maintains pressure in your arteries and your heart pumps against it. Blood pressure numbers reflect your arterial pressure when your heart pushes blood through your system, and also when your heart rests between beats. The "active" pressure is the top number on your blood pressure reading. It is the "systolic" pressure. The "passive," or "resting," pressure is the bottom number, and represents the "diastolic" pressure. Healthy blood pressure numbers are 120 systolic over 80 diastolic, or slightly lower Blood pressure changes throughout your day, depending on your position, your anxiety level, and your activity level. Chronic high blood pressure increases your risk of cardiovascular disease and stroke, but temporary increases in blood pressure allow you to meet the demands you put on your body when you exercise. Without adequate pressure, your blood delivery system fails. so,yes !!
Is 152 over 76 a bad?
A blood pressure reading of 152 over 76 indicates that the systolic pressure (152) is elevated, as normal systolic values are typically below 120. This reading suggests hypertension, which can increase the risk of heart disease and other health issues if not managed. The diastolic pressure (76) is within the normal range, but it’s important to address the elevated systolic number. It's advisable to consult a healthcare provider for further evaluation and potential lifestyle changes or treatments.
Why is the mean arterial pressure not calculated as systolic plus diastolic divided by 2?
This is because the lengths of systole and diastole are different. Usually in a resting individual having his or her blood pressure taken, the amount of time spent in diastole is longer than the amount of time spent in systole. The length of time the heart is in diastole is approximately twice as long as it is in systole. Systole only occurs when the heart is actively contracting, the rest of the time is diastole. So mean arterial pressure is usually closer to one's diastolic pressure than systolic. As one's heart-rate increases and the length of diastole shortens, the mean arterial pressure is much closer to just the average of systolic blood pressure and diastolic pressure.
What does a systolic count of 164 and a diastolic score of 140 mean?
A systolic count of 164 and a diastolic score of 140 indicates severely elevated blood pressure, categorized as hypertensive crisis. This condition can pose serious health risks, including the potential for heart attack or stroke. Immediate medical attention is necessary to manage and reduce these dangerously high levels. Regular monitoring and lifestyle changes may also be required to address underlying causes.
What is normal blood pressure for 49 year old 5'5 woman who weighs 118?
While blood pressure can change from minute to minute with changes in posture, exercise, stress or sleep, it should normally be less than 120/80 mm Hg (less than 120 systolic AND less than 80 diastolic) for an adult age 20 or over. A diastolic (the bigger number) of 100-140 is normal. Any higher than 140 and you have high blood pressure aka hypertension. If you discover this you should see your physician to get checked out as hypertension can be indicative of heart or vascular disease.
Is blood pressure 229 over 125 and pulse is 105 is this in stroke and or heart attack area?
blood pressure should be below 120 systolic and 80 diastolic..thats the safe level.. but since ur pulse is high it changes the reading..it depends on what youre doing.. normal adult pulse is 60 to 100...
Is 140 over 78 consider high blood pressure?
A blood pressure reading of 140 over 78 is considered elevated. The top number (systolic pressure) is at the high end of the normal range, and the bottom number (diastolic pressure) is within the normal range. However, it is still important to monitor and possibly make lifestyle changes to prevent it from increasing further.
Is 139 over 79?
Yes, 139 over 79 is a way to express a blood pressure reading, specifically indicating a systolic pressure of 139 mmHg and a diastolic pressure of 79 mmHg. This reading is considered elevated, as normal blood pressure is typically around 120/80 mmHg. It may be advisable to consult a healthcare professional for further evaluation and potential lifestyle changes.
What causes the bottom number to be high?
The bottom number in a blood pressure reading represents diastolic pressure, which measures the pressure in your arteries when your heart rests between beats. A high diastolic number can be caused by factors such as increased vascular resistance, high salt intake, obesity, stress, and hormonal changes. Additionally, underlying health conditions like kidney disease or hormonal disorders can contribute to elevated diastolic pressure. Maintaining a healthy lifestyle, including a balanced diet and regular exercise, can help manage blood pressure levels.
