Mphamvu ya m'chiuno ndi m'mimba ilinso ndi mutu wapamwamba, womwe ndi mphamvu yayikulu.Ndipotu, chifukwa chiuno ndi mimba zili pafupi ndi pakati pa thupi lathu, zimatchedwa core.Choncho, core ndi liwu lokhazikika pano ndipo silikuyimira kuchuluka kwa kufunikira.
1, M'chiuno ndi pamimba sizingapereke mphamvu yothamanga, koma chifukwa chiyani othamanga amafunika kulimbitsa m'chiuno ndi pamimba.
Zoonadi, mphamvu yoyendetsa mwachindunji yothamanga makamaka imachokera ku miyendo yapansi, yomwe imakankhira thupi la munthu patsogolo poyendetsa pansi.Koma ngati mukuganiza kuti mukhoza kuthamanga mofulumira malinga ngati mukuchita masewera olimbitsa thupi, ndiye kuti mukulakwitsa kwambiri.
Pafupifupi masewera onse amafunikira mphamvu zokwanira za lumbar ndi m'mimba.Minofu yamphamvu ya lumbar ndi m'mimba imagwira ntchito yokhazikika komanso yothandizira pamayendedwe a thupi ndi kayendedwe kapadera.Mayendedwe aukadaulo amasewera aliwonse sangathe kumalizidwa ndi minofu imodzi.Iyenera kulimbikitsa magulu ambiri a minofu kuti agwire ntchito mogwirizana.Pochita izi, psoas ndi minofu ya m'mimba imagwira ntchito yokhazikika pakati pa mphamvu yokoka ndi kuyendetsa mphamvu.Panthawi imodzimodziyo, iwonso ndizomwe zimagwirizanitsa kwambiri mphamvu zonse, ndipo zimagwira ntchito yofunikira pakugwirizanitsa miyendo yapamwamba ndi yapansi.
Kuthamanga, molingana ndi mfundo ya fizikia kuti torque yozungulira imakhalabe yokhazikika mwa munthu wotsekedwa, tikatuluka ku phazi lakumanzere, thunthu lidzazungulira kumanja ndi phazi lakumanzere, lomwe liyenera kutsagana ndi kugwedezeka kwa kutsogolo. dzanja lamanja kuti muyese torque yozungulira kumanja.Mwa njira iyi, miyendo ya pamwamba ndi yapansi imatha kugwirizana mobisa kuti ikhale yokhazikika, Kenaka mu ndondomekoyi, minofu yamphamvu ya lumbar ndi m'mimba imakhala ndi gawo lofunika kwambiri pothandizira kumtunda ndi kumunsi ndikugwirizanitsa zomwe zapitazo ndi zotsatirazi.
Kaya ndi kugunda kwamphamvu kwa mwendo ndi kugwedezeka, kapena kugwedezeka kwa mkono wokhazikika kumtunda, kumafunika kutenga minofu ya lumbar ndi m'mimba ngati malo othandizira mphamvu zamagulu apamwamba ndi apansi.Choncho, tikhoza kuona kuti anthu omwe ali ndi chiuno chabwino ndi mphamvu za mimba amayamba kuthamanga.Ngakhale kuti kachulukidwe kake kakugwedezeka kwa mkono wakumtunda ndi mwendo wam'munsi ndi wokwera kwambiri, thunthu limakhala lokhazikika nthawi zonse.Anthu omwe ali ndi mphamvu zochepa zapakati akayamba kuthamanga, thunthu lawo limagwedezeka mopanda dongosolo ndipo chiuno chawo chimagwedezeka mmwamba ndi pansi.Mwa njira iyi, mphamvu yopangidwa ndi miyendo yapamwamba ndi yapansi imadyedwa mopanda kufunikira ndi chigawo chofewa komanso chofooka, chomwe chimachepetsa kwambiri kuyendetsa bwino.
