How Does Blood Pressure Increase During Exercise

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

Blood pressure rises – arteries constrict blood to the visceral area and skin, sending the blood to the extremities for maximum muscle effort.

1.  Blood pressure is the force of circulating blood against the walls of the arteries. The pressure of blood in the arteries correlates directly to the amount of blood pumped by the heart and the amount of resistance in the

Blood pressure (BP) as defined by Marieb and Hoehan (as cited in Peate & Wild, 2012) is the pressure that the blood puts on the blood vessel walls as the blood travels around the body controlled by the heart. The strength of the blood pushing on the blood vessel wall is the BP reading. According

A parasympathetic response called Vasodilation happens. Blood vessels directing to the muscles dilate to allow more oxygen to be used. The blood pressure will drop because of the dilation. When we exercise our body will heat up causing blood vessels around our skin to dilate, more blood flows and help to reduce the excess heat in out body.

Exercise is a strong influencer of both heart rate and blood pressure. Isometric exercise, or exercise that involves muscle contraction but not movement, moderately increases the demand for oxygen in the skeletal muscles. Dynamic exercise, or aerobic exercise involving movement, greatly increases the demand for oxygen in skeletal muscle. Both of these exercise types lead to increase in both systolic blood pressure and heart rate to increase blood flow to the active tissues

The heart pumps blood into the arteries and the force of the blood pushing against blood vessel walls is called blood pressure. Arteries carry the blood throughout the body. High blood pressure is also know as hypertension and is very dangerous in many different ways. One way is that it makes the heart have to work harder in order to pump the blood to the body. Secondly it contributes to hardening of the arteries and lastly, it also contributes to heart failure. A healthy heart is essential to life and having high blood pressure it not healthy for the heart. It has been proven that there are many different causes that have been linked to high blood pressure.

The hearts mass and volume increases and cardiac muscle undergoes hypertrophy. It is the left ventricle that adapts to the greatest extent. As well as the chamber size increasing as a result of endurance training. A person’s stroke volume will also increase as an increase in blood plasma and blood volume occur and reduced heart rate which increases the diastolic filling time. This increased filling on the left ventricle increases its elastic recoil thus producing a more forceful contraction. So not only is the heart filled with more blood to eject, it expels a greater percentage of the end-diastolic volume. A persons venous return increases due to the higher cardiac output. Capillarisation occurs. This is the increased amount of capillaries over the muscles which mean more blood flows which will give you more oxygen, and nutrients so you will be able to participate in the exercise longer. There will be more capillaries present so the quicker the oxygen will get to the muscles. A decrease in the persons resting heart rate means they are able to recover quicker after an activity. Arterial walls will become more elastic which allows greater tolerance of

Blood pressure is the force exerted by the blood on the inner walls of the veins/vessels. In many cases, when blood pressure is too high a multitude of chronic diseases can occur such as heart disease, atherosclerosis, and negatively impact every blood vessel that travels around your body. According to your blood pressure results (High Blood Pressure stage 1 Hypertension), you are in the unhealthy range putting you at risk for these diseases and others like them. This can be a result of sedentary lifestyle, poor diet, lack of exercise, smoking, drinking and etc… Blood pressure is typically inconsistent, for example is can vary by just walking around or by being nervous but your results indicate that it may be high regardless. However, it is

Blood pressure measurement is important because measuring blood pressure is a preventive technique to find any risk for hypertension and cardiovascular disease. In addition, measuring resting blood pressure is used to evaluate and compare the impact of exercise on the blood pressure. Also, what type of exercises will affect the blood pressure; for example, high intensity or a moderate intensity workout. The risks that are associated with high resting blood pressure are cardiovascular disease, atherosclerosis, heart attack, or stroke. Measuring blood pressure during exercise is important because it plays a big role in the output of the heart. In addition, provides information on myocardial oxygen consumption and calculates rate pressure from

Compared with systolic pressure, diastolic pressure has a rather mild increase when intensity of exercise increases.

During exercise the blood pressure will increase because the muscles will need more oxygen to use if more exercise needs to be done. As the muscle continues to work, the heart rate must also increase to make sure that enough blood is being pumped around every part of the body. This would mean that systolic pressure increases because of the pressure in your heart when the muscles contract. In the other hand the diastolic pressure should be the same so there should be little or no changes to the pressure. This is because the blood vessel like the arteries become dilated so any heat can be exerted or escape.

To produce ATP through cellular respiration, the body demands oxygen from its cells. The blood in the circulatory system carries this oxygen. The heart, understanding that more oxygenated blood is needed when completing more physically draining activities, works much harder and faster to pump blood to the muscles, so more energy can be produced and used by the body. When there is a higher demand for oxygen, there is much more pressure on the heart. As the heart contracts and relaxes much faster and at a much higher pressure, both the systolic and diastolic pressure in the body increases.

Exercise increases the cardiac output and the blood pressure. Therefore, to obtain an accurate blood pressure reading wait 20 to 30 minutes following physical activity. Race is another factor, for unknown reasons African American over the age of 35 tend to have higher reading than European Americans. Also, younger female often has a lower blood pressure than males of the same age. However, postmenopausal women tend to have higher blood pressures. Stress stimulate the sympathetic nervous system which increases cardiac output and vasoconstriction of the arteries as a result the blood pressure increase. Fever can increase the blood pressure due to an increase in the metabolic rate. In contrast, external heat result in vasodilation which decrease

The speed of movement that occurs through the blood vessels depends on the pressure that is applied on the human’s blood as well as the diameter of the human’s blood vessel. If the diameter is to increase or decrease the pressure will differ inversely. If the pressure is to increase, then the diameter will decrease. The heart rate also affects pressure as well. The greater the speed of the heart contraction (pump) the increase of blood that will flow through it, resulting in the pressure being higher (Marieb ; Hoehn;, 2010).
