Ukuphumla ngaphandle kwexesha emva komsebenzi kwindawo evulekile, ngaloo ndlela siqinisekisa ukubonelelwa ngokufanelekileyo kwe-oksijini emzimbeni wethu. Iimleksile zale nkunkuma ziyimfuneko kakhulu kwiinkqubo eziqhelekileyo zeenkqubo ze-biochemical, ngexesha apho amandla akhululwa emzimbeni womntu. Ngokuqhelekileyo emoyeni, thina ngokwethu siza kulahlwa yindlala yomoya. Yintoni ekhokelela kuyo?
Okokuqala, ukufumana amandla okufuneka enze iintlobo ezininzi zezenzo zomzimba (kokuzivocavoca umzimba kunye nomsebenzi wengqondo), umntu kufuneka adle iintlobo ezininzi zezondlo nsuku zonke. Phakathi kwezinye izinto ezibalulekileyo zesondlo zingabizwa ngamaprotheni, amafutha kunye nee-carbohydrate. Xa zikwahlukana, iamolekyuli ze-oxygen zisetyenziswa. Ngokuvakalayo emoyeni ovulekileyo, sithola inani elaneleyo le nkunkuma. Kodwa ukuba umntu uchitha ixesha elide emsebenzini wakhe kwiofisi epholileyo kwaye ngethuba lokuphumla alishiyi iindonga zendlu yakhe, ngoko, ngokulandelana, kunye nokunciphisa ukungena kwe-oksijini emzimbeni, ukwahlukana kwezondlo ezinikezwa ukutya akukwenzeka ngokunyanisekileyo. Ngexesha elifanayo, ukutya kukugqithisileyo, ubunzima bomzimba obugqithisiweyo bubonakala, kunye neenkqubo zokuvumba komzimba emathunjini zikhula. Ukuphumla emoyeni omtsha, sinika isivinini esifanelekileyo se-oxidation yabathengi bamandla abakhulu emzimbeni wethu - i-carbohydrates namafutha.
Okwesibini, ngokuhlala uhlala emagumbini ahlambulukileyo, i-hemoglobin ibopha igazi elincinci kwi-oksijeni, eyonakalisa ukunikezelwa kweeseli zamathambo ahlukeneyo nale nkunkuma. Ukungabi nomoya omtsha kunceda ekuphuhliseni i-oksijini yindlala, enobungqina bezinto eziphazamisayo emsebenzini wezitho ezahlukeneyo zomzimba kwaye kunokukhokelela ekubonakaleni kwezifo ezinzulu.
Okwesithathu, ngexesha elide lokungahoywa ngokuphumla, ehleliwe emoyeni omtsha, amandla omsebenzi omntu ayancipha. Inyaniso kukuba ubuchopho (ilungu elibaluleke kakhulu ekulawuleni izenzo zomzimba) lugxininisa kakhulu ukungabikho kwomoya. Ngenxa yoko, ukunciphisa ekusebenziseni le nkunkuma kukhokelela ekuphuhliseni ukhathala okwanda kunye nokubonakala kweempawu zentloko.
Ukongeza, ukuphumla emoyeni omtsha, simele sitshintshe ngenkuthalo kunye neendleko zalokhu, ukubonelela ngokuzilolonga umzimba ngamaqela ahlukeneyo omzimba wethu. I-Motor activity yenza ukuba kugcinwe ithoni ye-muscle, kuphuculwe ukunikezelwa kwegazi kuzo zonke izitho zomzimba kwaye ngoko kuqinisekisa ukuthuthwa okufanelekileyo kwe-oksijini kuwo onke amaseli kunye nezicubu.
Njengoko ubona, ukuhlala emoyeni omtsha ngexesha lokuphumla ngeveki okanye ngokuhlwa emva komhla wokusebenza kuya kunceda ukubuyisela amandla omzimba ngokukhawuleza. Iintlobo zemisebenzi eyenziwa ngethuba leeholide, kuxhomekeke kwindawo yokuhlala kunye nexesha le-year, ingaba yinto eyahlukileyo-ukugijima, ukudlala i-badminton, ukubhukuda, ukukhwela okanye ukuhamba nje. Ukuba awunalo ithuba lokuphuma edolophini, ngoko uhambahamba epakini elisondeleyo okanye kwisikwere - ubuninzi bezityalo kule mimandla kuncedisa kwi-concentration ephezulu ye-oksijini emoyeni. Kodwa ukwenza ukusa kwantambama okanye kusihlwa emgwaqweni omkhulu oxakekileyo (oqhele ukubonakala kwizitrato zeedolophu ezinkulu) akukafaneli kubekho. Emva kwakho konke, umoya onobuninzi obuninzi obuvela kumagesi okuphela kweemoto ayinakubizwa ngokuba yintsha, kwaye xa ukuqhuba imiphunga yethu kuya kuba yinyameko ukufumanisa zonke izinto eziyingozi. Ngoko ke, kungcono ukugijima kwi-racetrack yezemidlalo okanye, nokuba bhetele, kwizikwere zedolophu ezinezityalo eziluhlaza.
