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.
