How might regular cardiorespiratory exercise affect hypertension?

Answer 1

Exercise is most likely going to increase systolic blood pressure. This is to increase the amount of oxygen getting to your muscles as muscles need oxygen to function. This is also the reason why you need to breathe a lot more during exercise.

Answer 2

Blood pressure is meant by the lateral pressure exerted by the flowing column of blood to the blood vessels. Normally it is divided into two categories- Systolic blood pressure (SBP) and Diastolic blood pressure (DBP).

Heart supplies blood to all the structures of body by contraction and relaxation. SBP is meant by the blood pressure following full contraction of the heart. DBP is the blood pressure when the heart is in the state of full relaxation.

About 20% of the world populations are suffering from high blood pressure.

A sedentary lifestyle poses a key risk factor for different cardiovascular diseases. Those who do not go for any work out are at a 30-50 percent increased risk of developing hypertension (high blood pressure). Researchers have proved in various clinical trials that exercise can reduce blood pressure in hypertensive and normotensives (persons with normal blood pressure).

Exercises are of tow types- Aerobic (Dynamic) exercise and Isometric (Static) exercises. Aerobic exercise engages large group of muscles for doing rhythmic and repetitive movements. These are walking, jogging, cycling, jumping and swimming. In the gym, they have developed some sets of exercise module for aerobic workout.

Isometric or Static exercises are those where our body does not move. Instead, there is sustained contraction and relaxation of muscles. Examples include- weight lifting, bench press etc.

More oxygen is consumed when we do aerobic exercises (Thus the name-aerobic). There is more demand for oxygen as it is depleted from our body. As blood carries oxygen and other nutrition in our body, the heart faces the challenge to deliver the increased demand through the circulatory system of different blood vessels. Thus, the SBP rises promptly while the DBP lowers to some extent or remains normal. The heart rate and the force of contraction are increased.

Static or isometric contraction of the muscle means contraction of a muscle against a load. There is no change in the muscle length. Therefore, there is mild to moderate increase in the cardiac output with mild or no increase in oxygen consumption. This mild boost does not have significant effect on the activity of the heart and there is little or no raised heart rate. The peripheral blood vessels contract and the combination of increased cardiac output, vasoconstriction and changes in the pulses rate have a peculiar effect on blood pressure. Both the SBP and DBP are increased but not to the amount as SBP.

Regular aerobic exercise lowers SBP by 3.84mm of Hg and the DBP 2.58 mm of Hg.

Answer 3

Regular exercise typically decreases blood pressure. While blood pressure would be high during exercise, it strengthens your heart and makes it healthier, therefore bringing your blood pressure closer to an ideal level.

Answer 4

hypertension may be reduced immediatly following and for almost 24 hours after cardio respiratory exercise

Answer 5

blood ressure would increse
