Effects of Exercise In order to meet the increased energy demand during exercise, the cardiovascular institution has to work more quickly. The cardiovascular institution carries oxygen-rich blood to the lungs in addition to supplying oxygen to the muscles and supplies fuel (nutrients and oxygen) to the functioning tissues of the body. The effects of exercise on the cardiovascular institution can be studied in two ways at Effects of Exercise

Immediate Effects of Exercises

Such as listed below Effects of Exercise

(a) Decrease in heart rate:

In general, the heart rate of a human is about 72 beats per minute in resting condition, whereas a player’s heart rate is 28 to 40 beats per minute. The heart becomes so efficient as a result of regular exercise that even just beating 42 times per minute replenishes blood in the muscles of the whole body. This results in less loss of energy.

(b) Increase in stroke volume:

As the intensity and duration of exercise increases, the amount of blood coming out of the left ventricle of the heart (stroke volume) increases with each stroke. The stroke volume in a normal person’s resting state is 50 to 70 millilitres per beats, while it increases from 10 to 150 millilitres per beats during intense exercise. Therefore, exercising regularly increases stroke frequency.

(e) Increase in cardiac output:

Depending on the intensity and duration of exercise, the amount of blood pumped per minute by the heart also increases (cardiac output). In the case of the beam, the cardiac output of a normal person is about 5 liters/minute, which increases from 20 to 40 liters/minute during intense exercise.

(d) Increase in blood flow:

Due to exercise, the cardio-vascular system increases the supply of energy to tissues that are in urgent need of oxygen and distributes less blood to those tissues which are less than Oxygen is required.

(e) Increase in blood pressure:

Blood pressure also increases due to an increase in blood supply during exercise. If exercise is done regularly then the blood pressure level becomes regular.

2. Long Term Effects of Exercises

Regular exercise also has many long term effects on the cardiovascular system. Such as ta)

(a) Increase in strength and size of muscles:

By exercising regularly, the heart has to work more due to which the size and strength of the heart muscle increases. It has been proved by various research that by exercising regularly the walls of the heart also become strong and thick.

(b) Increased heart efficiency:

Heart rate decreases in resting condition due to regular exercise, ie the heart becomes more efficient. Hence During rest, it does not need to beat fast to pump blood to meet the requirement of the body.

(c) Increase in cardiac output:

To meet the increased debt demand during exercise, the blood has to flow rapidly. Therefore, regular exercise also increases cardiac output.

(d) Increase in blood flow:

During exercise, blood circulation increases to supply more oxygen to the muscles. Due to excess blood circulation, the blood cells (Capillaries) widen due to which the distribution of blood becomes better.

(e) Increase in blood cells:

By regular exercise, red blood cells responsible for transporting nutrients and oxygen to the muscles in the body and white for the good health of the person The number of white blood cells also increases.

(f) Controlled blood pressure:

Due to regular exercise, there is a decrease in the highest and lowest blood pressure, due to which the blood pressure in the normal state of the person remains regular.

(g) Increase in volume of blood:

Blood volume is also reduced due to an increase in blood plasma volume by exercise. Also, there is an increase in red blood cells.

(h) Improvement recovery time:

Improvement recovery time by regular exercise. Due to this, the rate of respiration also becomes normal after rapid physical activity and the recovery of power also happens quickly. That is why the heart rate of a regular exerciser is higher Speed ​​becomes normal sooner than expected.

(i) Less chance of heart disease:

Due to regular exercise, the size of blood vessels gradually increases due to which there is no obstruction in them, ie, doing regular exercise. Risk of cardiovascular diseases Decreases.

(j) Enhances. Heart performance:

According to the intensity and duration of exercise, the heart has to work at a fast pace to meet the increased demand. Which is a kind of exercise for the heart itself. The heart muscle develops due to an increase in the rate of beats, due to which the size of the heart increases. This makes the heart more powerful and efficient. all about the Effects of Exercise.
