Inkcazo yelungelelaniso lomzimba lixabiso elikuvumela ukuba uqinisekise ukuchaneka komlinganiselo wesisindo somzimba womntu kunye nokukhula kwakhe. Ukubalwa kwesalathiso somzimba womntu kunceda ukuvavanya ukuba kukho ukuhluka kobunzima, ubuncinane okanye ubuninzi.
Isalathisi somzimba womzimba siqhelekileyo kubafazi
Izikhombisi zengxowankulu yamanqaku zenyama zaphuhliswa emva kowe-1869 ngumfundi waseBelgium kunye neenzululwazi uAdolf Ketele. Ukuqwalasela le ncwadana, ifom yehlongozwayo:
I-BMI (i-mass mass index) = ubuninzi / ukuphakama kwisikwere
Oko kukuthi, isalathisi somzimba silingana nomzimba oqokelelwe yikwere yokuphakama ethathwa ngamamitha.
Ngokomzekelo, ngokunyuka kwama-160 cm kunye nobukhulu beekhilo ezingama-55, siphumo siphumo sesi-55 kg / 1.6х1.6 = 55 / 2.56 = 21.48.
Iziphumo ezifumeneyo zichazwa ngokuhambelana nale miqathango elandelayo:
- 16-18.5: ubunzima bomzimba obaneleyo;
- 18.5-25: ubunzima bomzimba obuhle;
- 25-30: iimpawu zokuqala zokunyanya ;
- 30-35: ukukhuluphala kwesidanga sokuqala;
- 35-40: i-degree degree fetes.
Nangona kunjalo, isalathisi sobutyebi bomzimba esifanelekileyo kuphela kubantu abadala nakwabo abangabandakanyeli kwimidlalo kwiqondo lobugcisa. Isisindo esifanelekileyo somzimba wabagijimi sinokuphakama kunabantu abangabandakanyeli kwimidlalo, ngenxa yokwanda komzimba.
Isalathiso sobunzima besibalo sabasetyhini ngaminyaka
Xa ubala isalathisi somzimba, kufuneka uqwalasele iminyaka yobudala bomntu. Emva kwakho konke, ngokukhula, umntu ngamnye ukhula ngokunyuka, kwaye oku kubonwa njengesiqhelo.
Iimpawu zesalathisi somzimba njengemisebenzi yobudala (index index):
- 19-24 iminyaka: 19.5;
- 25-34 iminyaka: 23.2;
- 35-44 iminyaka: 23.4;
- 45-54 iminyaka: 25.2;
- emva kweminyaka engama-55: 27.3.
Ukunqongophala kunye nobunzima obuninzi kunobungozi kumzimba. Ngoko ke, ungazami ukufikelela kumanani amancinci. Ngomlinganiselo ophantsi umntu uhlaselwa zizifo ezahlukahlukeneyo aze alahlekelwe umsebenzi.
Ukongeza kwi-formula ye-Ketele, kukho ezinye iifomula ezenza kube lula ukubala i-index mass body. Enye yezona zidumileyo yiNkcazo ye-Broca, esetyenziselwa abafazi, abakhulayo ngo-155-170 ngamentimitha. Ukufumanisa ubunzima bomzimba obufanelekileyo, kubalulekile ukususa inani elingu-100 ukusuka ekukhuleni komntu ngamasentimitha, kwaye ke i-15% yabasetyhini kunye ne-10% yamadoda.
Amanqaku omzimba omzimba anika iziphumo ezifutshane. Baya kukhokelwa, kodwa musa ukuthatha inyaniso. Imizimba yezikhombisi zengqungquthela aziqwalasele ezinye izinto ezichaphazela ubunzima obukhoyo: umthamo kunye nesisindo semisipha yomzimba, inani lemali edibeneyo, umlinganiselo wamafutha kunye nezihlunu.
