Sibandakanya iimveliso esicinga ukuba ziluncedo kubafundi bethu. Ukuba uthenga amakhonkco kweli phepha, sinokufumana ikhomishini encinci. Nantsi inkqubo yethu.

Ushwankathelo

Ukuba wenza umthambo rhoqo, usenza ukhetho lokutya olusempilweni, kwaye ungaliboni isikali esidubulayo, isenokuba lixesha lokuvavanya ipesenti yamafutha omzimba wakho.

Xa uzama ukunciphisa umzimba, ukulinganisa amanqatha omzimba ngokulinganayo kubalulekile njengokulinganisa ubunzima bakho bebonke.

Kungenxa yokuba imikhwa esempilweni, njengokuzilolonga, inokwakha izihlunu. Ukwanda kobunzima bemisipha kunokwenza ukuba inani kwisikali lihlale lilingana okanye, kwezinye iimeko, lonyuke, nokuba ulahlekelwa ngamanqatha kwaye uya kuba nethoni ngakumbi.

Enye indlela yokuvavanya inkqubela phambili yakho kukunyathela kwinqanaba lamafutha omzimba. Ngelixa ayizizo kuphela iindlela zokumisela ubunzima bomzimba obunempilo, ukulinganisa amanqatha omzimba wakho kunokukunceda ubone ukuba ngaba iinzame zakho zokunciphisa umzimba ziyasebenza.

Ukuba awuzami ukunciphisa umzimba, amanqatha omzimba anokukunceda ufumanise ukuba unamafutha aphilileyo ukuya kwizihlunu.

Izikali zamafutha omzimba azizizo zonke izinto ezingenangqondo, kodwa zezinye zeendlela zokulinganisa amanqatha omzimba wakho phakathi kotyelelo nogqirha wakho okanye umqeqeshi wakho.

Zisebenza njani?

Izikali zamafutha omzimba kulula ukuzisebenzisa. Unyathela nje esikalini, kwaye isixhobo silinganisa ubunzima bomzimba wakho kunye neepesenti ezithelekelelweyo zamafutha.

Izikali ezinjalo zisebenza ngoncedo lwezivamvo eziphantsi kweenyawo zakho ezisebenzisa impedance ye-bioelectrical. Xa unyathela esikalini, umbane omncinci obaleka unyuka ngomlenze wakho nangapha kweepelvis, ulinganisa inani lokuchasana namafutha omzimba.

Emva koko, ii-sensors kwisikali zilinganisa inqanaba lokuchasana okwangoku njengoko kudibana nomnye umlenze wakho.

Kuxhomekeka kudidi lwamaqondo omzimba onawo, ulwazi lunokudibanisa ukuya kwi-smartphone yakho okanye kwi-smartwatch, kunye nazo naziphi na iiapps zomzimba onokuba nazo.

Njengomthetho wesithupha, ukuxhathisa okukhulu komzimba kuthetha ipesenti ephezulu yamafutha. Oku kungenxa yokuba amanqatha aqukethe amanzi amancinci kunezihlunu, ke iyajiya kunesihlunu kwaye kunzima ngakumbi ukuhamba ngoku.

Ngaba zichanekile? | Ukuchaneka

Ngokubanzi, izikali zamafutha omzimba zinokubonelela ngoqikelelo olubi kuphela. Ngelixa kukhuselekile ukusetyenziswa, zininzi izinto ezinokuchaphazela iziphumo zakho. Oku kubandakanya:

• Isini sakho. Abasetyhini ngokwendalo banamanqatha omzimba amaninzi kunamadoda.
• Apho ugcina khona amanqatha emzimbeni.
• Ukukhulelwa. Ezi zikali azikhuthazwa ngexesha lokukhulelwa.
• Iminyaka yakho. Ezi zikali zabantwana.
• Ukuphakama kwakho nesiqu sakho.
• Ukunyamezela rhoqo kunye noqeqesho lokumelana.

Zithini izinto ezilungileyo nezingeloncedo kumanqatha omzimba?

Esona sibonelelo sikhulu sokusebenzisa olu hlobo lwesikali kukuba ungawalinganisa amanqatha omzimba wakho kwintuthuzelo yekhaya lakho nangaliphi na ixesha, konke ngaphandle kokuya ejimini okanye eklinikhi.

Nangona kunjalo, ezi zikali azichanekanga ngokupheleleyo. Awufuni ukubenza umlinganiso wakho kuphela kwimpilo yakho iyonke.

Enye into ebuyayo kukuba amanqanaba omzimba awathatheli ngqalelo ezinye izinto ezinokuthanani namanqatha omzimba, anjengendawo onokuba unayo kuyo.

Umzekelo, oogqirha bahlala bexhalabile ngakumbi ngamanqatha omzimba agxile kwindawo ekumgama ophakathi kuba oku kungonyusa umngcipheko weemeko ezithile zempilo, njengesifo sentliziyo.

Isilinganiselo samafutha omzimba sinokukuxelela kuphela ipesenti iyonke kwaye ayisiyiyo apho emzimbeni ugcina amanqatha anokuba yingozi.

Amafutha omzimba ngokuchasene neBMI

Isalathiso sobunzima bomzimba (i-BMI) sisalathiso esithembeke ngakumbi sempilo yakho iphela endaweni yokubala kwinqanaba lamafutha omzimba kuphela. Ngelixa i-BMI ingenakulinganisa amanqatha, inika umfanekiso opheleleyo wokuba ingaba ukwinqanaba elifanelekileyo lobunzima bokuphakama kwakho nobudala bakho.

I (CDC) ichaza ezi ngcebiso zilandelayo kubantu abadala:

Ungasebenzisa iikhalityhuleyitha ezikwi-Intanethi ukumisela i-BMI yakho, efana ne-National Heart, Lung, kunye ne-Blood Institute.

Icala elisezantsi lokuthembela kwi-BMI kukuba ayilinganisi amanqatha omzimba. Ke, iimbaleki ezinemisipha emininzi, umzekelo, zinokuba ne-BMI ephezulu esekwe kubunzima bayo kunye nokuphakama.

Kwakhona, iCDC ithi abasetyhini, abantu abadala abadala, kunye nabantu abanemvelaphi yaseAsia ngokwendalo banamanqanaba aphezulu amafutha emzimbeni. Zonke ezi zinto zinokuthintela ukuthembeka kwe-BMI njengomlinganiso wakho kuphela wezempilo.

Ezinye iindlela zokulinganisa amanqatha omzimba

Ngelixa ukunyathela kwisikali yeyona ndlela ilula yokulinganisa amanqatha omzimba, zikho ezinye iindlela onokumisela ngayo ipesenti yamafutha omzimba. Ngaphandle kwe-BMI, ungabuza umboneleli wakho wezempilo ngezi ndlela zilandelayo:

Imilinganiselo yesinqe

Enye into ebuyela umva kumanqanaba amanqatha omzimba kukuba akakuxeleli ukuba ungakanani amafutha owabambe emanqeni, athathwa njengomngcipheko wokuba:

• izifo zentliziyo
• uhlobo lwe-2 yeswekile
• isifo sesibindi esinamafutha

Ukulinganisa i-esinqeni sakho kunokunceda ukugcwalisa iziphumo zomzimba wakho.

Amanqaku athi umngcipheko wesifo sentliziyo kunye neswekile uyanda ukuba ungumfazi onesilinganiselo esinqeni esingaphezulu kweesentimitha ezingama-35 (88.9 cm) okanye indoda enomlinganiso wesinqe ongaphezulu kweesentimitha ezingama-40 (101.6 cm).

Abaxhasi

Rhoqo isetyenziswa ziingcali zokomelela komzimba, abakhweli basetyenziselwa ukujija ngokoqobo iifolokhwe zesikhumba sakho (zihlala zijikeleza esinqeni okanye esinqeni) ukuqikelela amanqatha omzimba wakho.

Ukuchaneka kwale ndlela kuyahluka. Iziphumo zinokuchaneka ngakumbi okanye ngaphantsi ngokuxhomekeke kubuchwephesha bomntu othatha imilinganiselo.

Isikali esine-x-ray absorptiometry (DEXA)

Ngokuqhelekileyo isetyenziselwa ukulinganisa ubunzima beethambo ukuxilongwa kwe-osteoporosis, i-DEXA iskena nazo zindlela ezinokuthenjelwa zokulinganiswa kwamafutha omzimba kwaye zinokuthenjwa kunokuthembela kwi-BMI kuphela.

Ukufumana olunye lwezi skena, kuya kufuneka ufumane iziko elinezixhobo. Izikena zinokuba nexabiso kuxhomekeka kwindawo okuyo kwaye zinokungagutyungelwa yi-inshurensi.

Izixhobo zokulinganisa amanqatha aphathwayo

Olu vavanyo lomlinganiso wamanqatha omzimba lusebenza ngokufanayo nolo lwesikali, ngaphandle kokuba alilinganisi ubunzima bakho. Kukho izivamvo kwelinye icala lesixhobo esilinganisela amanqatha omzimba wakho njengoko ubambe isixhobo phambi kwakho.

Izixhobo zokulinganisa amanqatha aphathwayo azichanekanga njengezinye iindlela, kodwa kulula ukuzisebenzisa kwaye zitshiphu.

Uvavanyo lobunzima bamanzi (hydrodensitometry)

Olu vavanyo lusekwe kukuqaqamba kobunzima bomzimba wakho. Amafutha adada ngokulula kunesihlunu. Ngokusekwe kukuqaqamba komzimba wakho kunye nobunzima bakho, umntu olawula uvavanyo unokubala ipesenti yamafutha omzimba wakho.

Ukuvavanywa ngaphantsi kwamanzi kuthathwa njengesixhobo esifanelekileyo sokulinganisa amanqatha omzimba. Nangona kunjalo, kunokuba nzima ukufumana iziko elinakho ukwenza olu hlobo lovavanyo. Uvavanyo lusenokungonwabisi.

IBod Pod

Ifumaneka kumaziko athile omzimba kunye namaziko ezonyango, iBod Pod sisixhobo ome kuso imizuzu embalwa ngelixa ilinganisa amanqatha omzimba wakho ngokufuduka komoya plethysmography (ADP).

Le ndlela inokuchaneka okufanayo xa ithelekiswa nokuvavanywa kwamanzi. Nangona kunjalo, ukufikelela kwezi zixhobo kuncitshisiwe, kwaye kuvavanyo kungabiza.

Yise kude

Izikali zamafutha omzimba zinokuba luncedo xa uzama ukulinganisa amanqatha omzimba wakho, kodwa azixeleli lonke ibali malunga nenqanaba lamafutha ukuya kwezihlunu. Endaweni yoko, ungazisebenzisa ezi zikali njengezincedisi kwezinye izixhobo.

Thetha nogqirha wakho malunga ne-BMI yakho, kunye nendlela onokulinganisa ngayo kunye nokulandelela ukwakheka komzimba wakho.
