Abstract
The subject of this research is the individual respiration constant calculated based on the respiratory musculature breathing equation. This non-experimental observation conducted on a sample of students from the Faculty of Sports and Physical Education in Belgrade (N=30). The measurement aimed at the acquisition and analysis of the average power of the surface electromyography signal (sEMG) in the protocols before and after prolonged respiratory retention. The results of the research showed that the individual coefficient of control break (Cp) represents a unique characteristic of the respiratory muscles of the subjects. In a relatively trained sample of young people of both sexes, it determined that after holding their breath, until the moment of the so-called "stroke" (progression of respiration to adapt to a stressful situation), recovery time has a linear course and is directly related to the engagement of the monitored respiratory muscles of the subjects, i.e., indirectly the capacity of the individual to assimilate O2 from the inhaled air. In the practical meaning of this research, we emphasize that individual results can be correlated with the equation of respiration of respiratory muscles, to find out and approach the original method for the presented personal respirational constant.
Highlights
The specificity of respiration, as a vital vegetative function, is reflected in the possibility of voluntary control to a certain extent, during an individually determined time
Through the analysis of surface electromyography records, this paper aims to gain insight into various respiratory phenomena that have been very popular in sports and training in recent years
The obtained indicator of relaxation time from the moment of „shock” at the end of breath-holding to complete normalization of the average surface electromyography (sEMG) power, is a significant respiratory capacity prediction indicator of the functional abilities status to assimilate oxygen from inhaled air faster, which is proportional to air holding time (BHT), confirming the first hypothesis (H1)
Summary
The specificity of respiration, as a vital vegetative function, is reflected in the possibility of voluntary control to a certain extent, during an individually determined time. In this way, it is possible to hold the own breath for a while, and in that way indirectly affect the respiratory tissues, and all other systems of the human body. The simplest is the one that follows the changes in the essential gases of the respiratory process: oxygen and carbon dioxide. Carbon dioxide eliminates as a final product. Carbon dioxide diffuses through the cell membrane 20.2 times faster than the oxygen
