Mpando uyenera kuthetsa vuto la kukhala; Mpando wa Ergonomic ndikuthetsa vuto la lokha.
Kutengera zotsatira za disclertem yachitatu ya lachitatu (L1-L5) zomwe zapezedwa:
Kugona pabedi, mphamvu yopota lumbar ndi nthawi ya 0,25 ya nthawi yokhazikika, yomwe ndi yopumira kwambiri komanso yabwino kwambiri ya msana wa lumbar.
Mu mawonekedwe okhazikika, mphamvu yopezekapo msana ndi 1.5 nthawi 1.5 Nthawi yokhazikika payimirira, ndipo pelvis satenga nawo mbali panthawiyi.
Ntchito yodzifunira, mphamvu ya lumbar spine ya muyeso wokhazikika nthawi 1.8 maulendo okhazikika, pomwe pelvis adakhazikika mtsogolo.
Mutu pansi patebulo, mphamvu ya lumbar spine yokhazikika payimirira maimidwe 2.7, ndiye kuvulala kwambiri kwa mawu a lumbar.
Makona ammbuyo nthawi zambiri amakhala pakati pa 90 ~ 135 °. Powonjezera ngodya pakati pa kumbuyo ndi khushoni, pelvis imaloledwa kubwerera. Kuphatikiza pa chithandizo chamtsogolo cha pilo la lumbar kupita ku lumbar msana, msana umakhala wowoneka bwino wowoneka bwino ndi mphamvu zonse ziwiri. Mwanjira imeneyi, mphamvu yotulutsa msana ndi 0,75 nthawi yomwe ili pachiwopsezo, yomwe siyikutopa.
Chithandizo cham'mbuyo ndi lumbar ndi mzimu wa mipando ya ergonomic. 50% ya vuto la chitonthozo limachokera ku izi, kutsitsa 35% kuchokera ku khushoni ndi 15% kuchokera pankhondo, mutu wamutu, wapamwamba ndi ena omwe amakhala.
Kodi mungasankhe bwanji mpando woyenera wa ergonomin?
Mpando wa Ergonomic ndi chinthu chopangidwa ndi umunthu wina aliyense ali ndi kutalika kwake, kuchuluka kwake komanso thupi. Chifukwa chake, ndi kukula koyenera koyenera komwe kungakulitse zotsatira za ergonomics, monga zovala ndi nsapato.
Pakati pa kutalika, pali njira zochepa kwa anthu omwe ali ndi kukula kwake (pansipa 150 cm) kapena kukula kwakukulu (pamwambapa 185 cm). Ngati mwalephera kupanga chisankho chabwino kwambiri, miyendo yanu ingavutike kukhazikika pansi, ndikulimba mutu ndi khosi lanu.
Kulemera, anthu owonda (pansi pa 60 kg) sakutanthauza kuti asankha mipando ndi thandizo la lumbar. Ngakhale zisinthidwe, chiuno chimangosintha komanso chosasangalatsa. Anthu onenepa (pamwambapa makilogalamu 90) osalimbikitsa kusankha mipando yayitali yotalika ma mesh. Mitengo idzakhala yosavuta kumira, ndikuyambitsa magazi osayenera kuzungulira kwa miyendo ndi kumva bwino mu ntchafu.
Anthu omwe ali ndi zowawa za m'chiuno, minofu ya minofu, mpando wa herniated, mpando wokhala ndi chidziwitso cha Screel kapena kumbuyo kwa msana wabwino komanso kuphatikizika kumayenera kulimbikitsidwa kwambiri.
Mapeto
Mpando wa Ergonomic ndi njira yosinthira, yosinthika komanso yosinthika. Ngakhale zitamba za erstnomic, sizingapewe bwino zovulaza zomwe zabweretsedwa.
