Abaningi bethu bachitha isikhathi esingaphezu kwesigamu samahora ethu okuvuka behlezi, uma-ke unobuhlungu beqolo,isihlalo esilungile se-ergonomicingakusiza ukuthi ulawule izinhlungu futhi idambise ukungezwani.Ngakho-ke isiphi isihlalo sehhovisi esingcono kakhulu sobuhlungu beqolo?
Eqinisweni, cishe zonke izihlalo zehhovisi le-ergonomic zithi zisiza ukudambisa izinhlungu emuva, kodwa akunjalo.Kulesi sihloko, empeleni sichithe amahora ambalwa sihamba ocwaningweni lwakamuva ukuze sithole ngendlela yesayensi ukuthi isihlalo esingcono kakhulu sehhovisi sobuhlungu beqolo kufanele sibukeke kanjani.
Uma kukhulunywa ngokukhululeka kobuhlungu beqolo, ikakhulukazi ubuhlungu obuphansi emuva, i-Angle ye-backrest ibalulekile.Kunezihlalo eziningi emakethe ezisiza ngokuma okuhle kokuhlala, kungaba nge-90-degree eqondile emuva noma nge-design engenamhlane, njengebhola le-yoga noma isihlalo esiguqayo.Zilungele ukuma kwakho kanye nomgogodla, kodwa zingase zibe nomphumela ophambene nobuhlungu bakho bomhlane.
Ucwaningo oluningi luye lwabonisa ukuthiisihlalo sehhovisiiyona engcono kakhulu yokuhlalisa abantu abanezinhlungu ezingezansi.Abacwaningi bafunde izikhundla ezihlukene zokuhlala futhi bahlola ukuthi ingakanani ingcindezi yesikhundla ngasinye esibekwe kuma-intervertebral discs ababambiqhaza.
Njengoba ubona, ukuhlala endaweni eqondile engama-intshi angu-90 (njengesihlalo sasekhishini noma isihlalo sehhovisi esingalungiseki) kudala ukucindezeleka okungamaphesenti angu-40 kunokuhlala endaweni ehlezi ngemuva nge-engeli engu-110 degree.Ezikhundleni ezihlukahlukene, ukuma kubeka ukucindezeleka okuncane kuzilwane ezinomgogodla, yingakho kudingekile ukuvuka futhi unyakaze njalo uma uhlushwa izinhlungu ezingezansi.
Kubantu abanobuhlungu be-back - ikakhulukazi ubuhlungu obuphansi emuva - ubufakazi busekela i-angle ehlezi etshekile ukuze kuncishiswe ingcindezi ebekwe kwi-disc.Besebenzisa ama-MRI scans, abacwaningi baseCanada baphetha ngokuthi indawo ekahle yokuhlala ye-bio-mechanical ukunciphisa ukucindezeleka komgogodla kanye nokugqoka kwe-disc. usesihlalweni nomhlane utshekele ngamadigri angu-135 futhi izinyawo ziphansi.Ngokocwaningo oluyisisekelo, i isihlalo sehhovisi esine-engeli ebanzikufanele kube yinto ehamba phambili kubantu abanezinhlungu emuva.
Ngenxa yalokho,isihlalo esiphezulu sehhovisi le-Anglekuyisinqumo esingcono kakhulu sobuhlungu obuphansi emuva.
