Imisipha yangemva kwe-extrinsic ingenye yezinhlayiyana ezimbili eziyinhloko zemisipha yokugulisa umgogodla. (Esinye isethi sinemvelo.) Imisipha yangemva kwe-Extrinsic neyangaphakathi ihlelwe ngokuvumelana nendawo yabo, nomsebenzi wabo.
Zombili izinhlanzi zangasemuva zangaphakathi nezangaphakathi ziyadingeka ekusekeleni umgogodla ngoba iningi lesisindo sethu lingaphambi kwethu. Ngaphandle kwemisipha enamandla eyayisemuva, kungenzeka ukuthi sihlehlisiwe ukunyakaza nokugxila kwethambo isikhathi esiningi.
Imisipha emhlane yangaphandle ikhona engaphandle komzimba. Nabo, bahlukaniswe ngamaqembu amabili - imisipha yangemva emhlane yangaphandle kanye nemisipha yangemva ephakathi.
Lesi sihloko sichaza isendlalelo esingenasici semisipha yangemva.
Ngenkathi jikelele, imisipha yangemva yangaphandle ikwazi ukulawula ukunyakaza kwengalo futhi idlala indima ekuphefumuleni, okuphawulekayo koqweqwe olungenasici kungukunyakaza kwesandla. (Ukuphefumula kuthonywa kakhulu yizingqimba eziphakathi komkhathi.)
Imisipha ye-Superficial Extrinsic Group
I-muscle group yangemuva yangaphandle ehlanganiswa nemisipha engama-4: I-trapezius, i-latissimus dorsi, i-levator scapula ne-rhomboids.
I-Trapezius Muscle
Esinye sezici eziphawulekayo zomzimba we-trapezius umumo wayo. I-trapezius (ebizwa ngokuthi "izicupho" ezimfishane) iyisiphako esikhulu esinqunyiwe esivela phakathi nangemuva phezulu, nasentanyeni nasemaphethweni.
Le misipha inemisebenzi eminingana, hhayi okungenani okuhilela ukuhambisa amahlombe (lawa angamapulangwe - abuye ahlolwe njengamatshumi amathathu ahlala emhlane). Ezinye imisebenzi ze-trapezius zihlanganisa ukufaka isandla entanyeni nasentanyeni imizamo kanye nokusiza ngokuphefumula.
I-trapezius muscle inezingxenye ezintathu: Ephezulu, ephakathi naphansi.
Funda ulwazi oluthe xaxa mayelana nezindawo zokunamathisela kanye nemisebenzi ye- muspezius muscle .
Latissimus Dorsi
Enye imisipha enesigxathu, i-latissimus dorsi, iyisidlali esikhulu uma usebenzisa izingalo zakho ukudonsa isisindo somzimba wakho. Ngenxa yalesi sizathu, kuvame ukubhekwa ngokuthi "umsizi wendoda." (I- latissimus dorsi nayo ibizwa ngokuthi "ama-lats" omfishane.) Amathisi asiza ngokuphefumula, futhi.
Ama-lats athatha indawo enhle kakhulu endaweni ephansi nangemuva. Baqala phansi kwe-thoracic umgogodla nezimbambo, i-thoracolumbar fascia nengxenye yethambo lakho le-hip. Bese befaka iphuzu elihle elifaka ngaphakathi kwethambo lesandla eliphezulu.
Levator Scapula
Umzimba we -scapula muscle uqala entanyeni bese uhamba phansi ukuze unamathisele ekhoneni labezindaba phezulu kwekhasi lehlombe. Umsebenzi walo ukuphakamisa ihlombe kuze kube sezindlebeni. Lesi senzo ngeshwa njalo "ku" kwabaningi bethu, okungaholela enkingeni enkulu yezintamo kanye nehlombe.
Rhomboids
Imisipha ye-rhomboid imisipha emibili ye-parallelogram (kwesokudla nangesobunxele) esukela emkhatsini womgogodla kuya emngceleni wangaphakathi we-scapula (ihlombe lamathambo.)
I-rhomboid ngayinye iqukethe ingxenye enkulu nencane, ebizwa ngokuthi, ngokulandelana i-rhomboid enkulu ne-rhomboid encane.
Nakuba izakhiwo ezimbili ezihlukene, ezinkulu nezincane zenza isimo esisodwa sonke futhi senze njengeyunithi yokucindezela ndawonye amahlombe ehlombe.
Ngenxa yesenzo salo (ngokucindezela amahlombe amahlombe ndawonye), ukubhekisela kuma-rhomboids wokuzivocavoca kokuphumula kungase kube umbono omuhle. Isenzo sokucindezela amahlombe amahlombe ndawonye (ekuqondeni umgogodla) kungasiza ekuguquleni imiphumela yokuhlala ekhompyutheni kanye / noma ezinye izinhlobo ze-post-kyphosis. Eqinisweni, kukhona ukuvivinywa kokuzivocavoca komzimba ongase ufune ukuzama khona manje.
