Intrathoracic Pressure

Intrathoracic pressure (IHP) is an important parameter in medicine and physical culture. It characterizes the air pressure in the chest, which is created by the respiratory movements of the lungs and the work of the heart. Typically, VGP is measured using a special device called a chest tonometer (cuff and phonendoscope).

The significance of VGP research is due to the opportunity to obtain valuable information about the functioning of the respiratory and cardiovascular systems and help in the diagnosis of various diseases, such as cardiovascular diseases, respiratory disorders, pneumonia, emphysema, asthmatic conditions, and respiratory tract pathologies. In addition, VGP is also used in the training activities of athletes, as well as in the development of interval training to assess the effectiveness of different modes of operation of the respiratory and cardiac pumps.

The value of VGP in the air during inhalation during inhalation is 9-11 kPa, and during exhalation it is 5-6 kPa. In a healthy person, the normal value can range from 6 to 18 kPa (kPa - kilopascals (also known as kilograms per square centimeter or hectopascals)). However, in people with respiratory or circulatory problems, the values ​​may differ, even without any changes. Thus, an accurate measure of VGP is a valuable tool for diagnosing various disorders related to the functioning of the lungs and heart, as well as in developing training programs for athletes.

Another important aspect of VGP research is its practical significance for sports. This is because the ability to produce a greater volume of inspired air is paramount to the success of athletes in achieving high performance, especially in aerobic and anaerobic sports such as skiing, long-distance running, etc. To assess and improve their VGP performance, athletes should conduct
