Vital lung capacity

Vital capacity of the lungs ( ЖЕЛ) is the most important functional parameter of the body, reflecting not only the state of the respiratory system, but also the circulatory system, perform one common task: they satisfy the body's need for oxygen.

The vital capacity of the lungs shows the total amount of air that can be perceived by the lungs after a deep inhalation followed by an exhalation.

GEL is determined using the spirometer. Currently, there are portable spirometers. The vital capacity of the lungs depends on the age, weight and sex, it linearly increases along with the body length:

• Wait 5 minutes,

• further, in 3-minute increments, 3 times in milliliters ZHEL;which can be compared with the due;

• you will get the actual value of the YEL, which is compared with the value characteristic for healthy people of your gender, height and age-for this you should multiply your height( in cm) by 25 for men and by 20 for women,

• take this duevalue for 100 percent,

• Calculate how much the actual value of your value of the YEL is different. The normal value of the JEL differs from that due not more than 15-20 percent.

After physical exertion, the vital capacity of the lungs decreases. In trained people, this decline occurs no more than 15 percent.

• Wait 5 minutes, determine the LEL using a spirometer 3 times at intervals of 5 minutes. In the future, use the average value,

• run for about 2 minutes in the field at a rate of about 180 steps per minute, raising the feet from the floor by at least 5 cm,

• immediately after the end of the run, determine the YEL.Decrease in LEL after physical exertion is due to increased blood filling of the vessels of the pulmonary( small) circle of blood circulation.

Evaluation:

• the result is considered bad if the GEL decreases by more than 200 mL,

• a decrease in the GIV after a load of more than 15 percent of the baseline indicates low fitness and reduced health, in particular the lack of functional reserves of the right divisionsheart and small circle of blood circulation.
