I-trapezoid yomzimba: isakhiwo kunye nomsebenzi

Imisipha ephezulu emva ibizwa ngokuba ngamaqela omzimba wezihlunu ezinamathele emagqabini ebhande lehlombe. Zihlelwe ngamacandelwana amabini. Uluhlu oluphezulu luyi-muspezoidal kunye ne-latitudinal muscle, eliphantsi liqukethe imisipha enkulu kunye encinci ye-rhombic.

Isakhiwo se-trapezius muscle

Esi sikhulu semisipha esiphezulu sinendawo kwindawo ephezulu yomqolo kwindawo engaphantsi ephantsi kwentamo. Inomfanekiso ofana noxantathu. Isiseko saso siphendulelwe kwikholam ye-vertebral, i-pepe isetyenziswe kwi-acromion. Ukuba uhlola imisipha ye-trapezius kumacala omabini omva, iya kufana nomfanekiso wejometri "trapezium". Ngenxa yoko bafumana igama labo. I-trapezoidal ye-muscle ihlukaniswe ngamacandelo amathathu:

- phezulu (intamo yommandla);

- phakathi (inxalenye ephezulu yamacala);

- ezantsi (phantsi kwe-scapula kunye nommandla ongaphantsi kwazo).

Iimisipha zinezikhwebu ezimfutshane zeetonon. Bakha i-rhombic pad kuphela kwiphondo ye-thoracic ne-lower vertebrae yomlomo wesibeleko. Iibhontshisi ze-muscle ziguqulela ngokubanzi kwi-scapula. Apha ziqhotyoshelwe kwi-axis yayo, kunye nokuphela kwe-acromial ye-clavicle kwaye ngqo kwi-acromion ngokwayo. Kwindawo yokuqhotyoshelweyo, phakathi kwendawo yokuqhotyoshela kweenqwelo ezinyukayo kunye nesiphakamiso se-scapula, kukho ibhokisi lebhokisi elincinane. Itholakala phakathi kwethambo kunye nethenda ngokwayo. Endaweni apho i-trapezius muscle ijoyina i-acromion, kukho isikhwama se-acromial bag. Kukhulu kakhulu. Ihamba emva kwe-acromion.

I-Trapezius muscle: imisebenzi

Lo msizi unemisebenzi emininzi, kodwa into eyona nto, eyona nto, ukuhamba kwe-scapula, enika ukuphakamisa, ukunciphisa nokujikeleza kwezitho ezingaphezulu. Makhe siqwalasele zonke iinkcukacha:

- kunye nokunciphisa ngokufanayo kwazo zonke iinxalenye zesisipha, kwimeko yesigxina esingagxininiswayo, i-scapula iyayisondela;

- kunye nokunciphisa ngokukhawuleza kweempepha eziphezulu kunye nezantsi, ithambo lijikeleza nge-axis;

- i-scapula iphakanyiswe yimithwalo ye-muscle ephezulu;

- I-muscle, xa ikhutshwe kumacala omabini, inceda ukuphazamisa ummandla wesibeleko, oku kukuvumela ukuba ubuyisele intloko yakho;

- ngokuqinisekiswa komgca omnye, inxalenye yangaphambili yentloko ijika kancane kwelinye icala.

I-muscle traidzoidal?

Ngoko, i-trapezius muscle iphezulu kumqolo. Ngokomlinganiselo walo, kunokwenzeka ukuba uthethe ngokuqinisekileyo ukuba umntu uthatha uqeqesho kumzimba okanye awukho. Ukuba umthamo we-trapezoid uqala ukukhula, i-neck circumference iyanda. Iba namandla ngakumbi kwaye ifakwe embossed. Ukufezekisa ukuba umsila we-trapezius we-back uzuze ukubonakala okukhulu kunye nokumangalisayo, akunzima kakhulu. Kule nto, kukho iisethi ezipheleleyo zokulandelela. Lo msila uqeqeshwe ngokunciphisa nokuphakamisa iingalo ngeesisindo, umzekelo usebenzisa i-barbell okanye i-bumbbells. Inxalenye engezantsi iguqulwa yindlela yokuhlenga idatha phantsi komthwalo weentlobo. Kodwa musa ukuqeqesha eli qela lemizimba. Oku kunokukhokelela ekunciphiseni kwamagxa. Kufuneka iguqulwe kwinkimbinkimbi.
