Sažetak
Predmet ovog rada je individualna konstanta respiracije, izračunata preko jednačine disanja respiratorne muskulature. Ovo, neeksperimentalno posmatranje je sprovedeno na uzorku studenata Fakulteta sporta i fizičkog vaspitanja u Beogradu (N=30). Merenje je za cilj imalo akviziciju i analizu srednjeg vremena snage signala površinske elektromiografije (sEMG) u protokolima, pre i nakon produženog zadržavanja akta disanja. Rezultati istraživanja su pokazali da pojedinačni koeficijent "kontrolne pauze" (Cp) predstavlja individualnu karakteristiku respiratornih mišića ispitanika. U uzorku relativno treniranih i mladih osoba oba pola, utvrđeno je da posle zadržavanja daha, do trenutka tzv. "udara" (progresija respiracije da se izvrši adaptacija na stresnu situaciju), vreme oporavka ima linearni tok i direktno je povezano sa angažovanošću praćenih respiratornih mišića ispitanika, odnosno indirektno kapaciteta ispitanika da brže asimiluje kiseonik iz udahnutog vazduha. U praktičnom značenju ovog istraživanja ističemo da je pojedine rezultate moguće korelirati sa jednačinom disanja respiratornih mišića, a sa ciljem saznanja i približavanja realnoj metodi za predočenu individualnu konstantu disanja.
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.
