Kuyini ukuma okuhle?Okubiliamaphuzu: i-physiological curvature yomgogodla kanye nokucindezela kuma-discs.
Uma ubhekisisa imodeli yohlaka lwamathambo omuntu, uzobona ukuthi nakuba umgogodla uqondile ukusuka ngaphambili, uhlangothi lubonisa ijika elincane lika-S elinwetshwe ngobude, lokho esikubiza ngokuthi ijika le-physiological.
Umgogodla womuntu omdala wakhiwe ama-vertebrae angama-cylindrical angu-24, i-sacrum, kanye ne-tailbone.Amalunga e-cartilaginous phakathi kwama-vertebrae amabili aseduze abizwa ngokuthi ama-intervertebral discs.Ukubaluleka kwe-disc intervertebral, empeleni, ukwenza i-vertebrae ibe nezinga elithile lokunyakaza, okubonisa ukubaluleka kwayo.
Kufanele ngabe uhlangabezane nalokhu:ngenkathiehlezi, umzimba uzoxega ngokungazi, kuze kube yilapho ukhalo lumisiwe ngokuphelele "lubhajwe" esihlalweni,naweuzothola ukuthi umgogodla ulahlekelwe ukugoqa okujwayelekile komzimbaninithintaingbac yakhok.Kuleli qophelo, ingcindezi engavamile isatshalaliswa kuyo yonke i-disc.Ngokuhamba kwesikhathi, kuzokucasula, ngaleyo ndlela kuthinte izinga lomsebenzi we-vertebrae, imiphumela ingacatshangwa.
Abanye abantu bathanda ukubeka izandla zabo phambi kwekhompiyutha futhi bazisonge.Lesi senzo sizokwenza i-thoracic vertebrae igobe kakhulu, ukugoba komgogodla womlomo wesibeletho kuba kuncane, okwenza ijika le-lumbar libe lincane futhi liqonde kakhulu.Isikhathi eside, lokhu kungase kubangele nezinkinga ze-lumbar.
Okubizwa ngokuthi ukuma okuhle kokuhlala ukugcina ukugoba okujwayelekile komzimba komgogodla womzimba, ukukhiqiza ukucindezela okufanele kakhulu, okusatshalaliswa ku-disc intervertebral phakathi kwama-vertebrae, ngesikhathi esifanayo, ukusatshalaliswa komthwalo we-static ofanele futhi ofanayo. kuzicubu zemisipha ezinamathiselwe.
Ngaphezu kokuma okuhle, udinga ukuzitholela wenaisihlalo sehhovisi le-ergonomic.
Umsebenzi oyinhloko weisihlalo se-ergonomicukuhlinzeka ngokusekela okuyisisekelo okhalweni ngokusebenzisa ilumbarukusekela.Ngokulinganisa amandla, ingemuva linikeza ijika elimise okwe-S ngemuva kwesihlalo, linciphisa ukucindezelwa kwe-lumbar spine kuze kube yilapho liseduze nokuma okujwayelekile okujwayelekile.Ngaphezu kokuba khona kokusekelwa kwe-lumbar, umklamo ogobile wengemuva lesihlalo uhambisana kakhulu nesimo semvelo sokugoba komgogodla womzimba womuntu, kungcono.
