Maitiro emazuva ano mumabhizimisi emafashoni ari kuchinja kune kunamata maitiro akakura eRubensian, kunyange muhupenyu hwezuva nezuva varume vachiri kunakidzwa nevasikana vashoma. Asi, sezvavanotaura, hapano nharo pamusoro pekuda, kune vanoda vakadzi vane zvinyorwa zvakasiyana. Kunyange zvakadaro, chimwe chezvinetso zvakakurukurwa zvinoramba chiri kurwisana nehuwandu hwehutundu hwemuviri. Mukuwedzera, nekuda kwetsika yeupenzi hwehupenyu, vakadzi vakawanda havana nguva yekuzvitarisira ivo uye panzvimbo yemitambo vanoshandisa zvakasiyana-siyana zvekudya. Uye pano iwe unogona kutotarisana nerimwe dambudziko, ikozvino kune zvakasiyana: anorexia. Mushure mezvose, vasikana vakawanda, vachiedza kuenzanisa chimiro mumhando dzakasarudzika, vachizvinyima ivo pachavo. Nokudaro, kuitira kuti usapfurikidza nekunyanyisa nekujekesa kana iwe uchida kuve nekurema kana kuuramba, kune chinhu chakadai sechimiro chemuviri mazita, chirevo chaicho chiri nyore.
Iko yakakosha mumuviri mashizha, kana BMI, inobatsira kutsanangurira zvakananga kuti kureba uye kuyerwa kwemunhu kunopindirana sei. Nhamba iyi yakagadzirwa kumashure muna 1869 nenyanzvi dzezvemagariro evanhu uye nhamba yematongerwo enyika Adolf Ketle (Belgium) saka saka anonziwo Quetelet index. Kuti tive nematendeti aone kuti muviri wei uhwo huchave hwakanaka, unogona kuverenga mutumbi wehuwandu huwandu, iyo yakagadzirisa uremu hwomudzimai mukati maro mumamita, mutsara. Iko ndiko, mutumbi wehuwandu hwemadzimai = uremu / urefu2.
Semuenzaniso, musikana anorema makirogiramu 65, uye kukwirira kwayo ndi168 cm. Chokutanga, zvakakosha kuendesa kukura kubva pamamendimita kusvika mamita: 168 cm = 1.68 m. Zvino tinoda kukwira ichi chiyero kune imwe nzvimbo yakasimba: 1.68 m * 1.68 m = 2.8224 m2. Kuziva chimiro icho muviri wehuwandu huwandu hwevakadzi hunotarirwa, tinoiona: 65 kg / 2.8224 m2 = 23.03.
Tafura yomuviri mass index
Nzvimbo yekutanga yekuverengwa kweBMI yevakadzi yakapedzwa. Uye kuitira kuti nhamba yacho inobatsira ive nechimwe chinhu chinokosha, tafura ye BMI yakagadzirwa. Kubva pane zvinorayirwa neWorld Health Organisation, kuenzaniswa kwehutano hwemuviri uye kukura kwayo, kwakaverengwa maererano neBMI yevakadzi, inofanira kureva zvinotevera:
- Muviri wehuwandu hwemadzimai hwevakadzi ndewe 16 kana pasi - munhu ane chirevo chemuviri mashoma;
- 16-18 - kushaya muviri kwakakwana;
- 18-25 - kazhinji muviri mumuviri index;
- 25-30 - kuwedzera muviri;
- 30-35 - kuneta kwechigarire chekutanga;
- 35-40 - kuneta kwechipiri chechipiri;
- 40 uye akawanda ndiwo mutumbi wehuwandu hwemadzimai ane uremu hwechidimbu chechitatu.
Izvo zvinofanira kunzwisiswa kuti, kuziva nzira yekuziva BMI, hazvibviri kuziva kana kunyatsorema kana kuti kwete, sezvo chiratidzo ichi chiri chakanaka uye hachifungi nhamba yakawanda yezvinhu. Saka, mutumbi wehutu huwandu, iyo inowirirana iyo iri kugoverwa kwe18-25, inogona kunge yakafanana kune munhu akakwana uye munhu ari kuita zvemitambo. Mukuwedzera, unofanirwa kufungisisa zera. Mukadzi wechimwechete anovaka semusikana ane mutsvuku anogona kuwedzera zvakawanda nokuda kwehumwe
Muviri mass index yekuzvitakura
Chinhu chinonakidza ndechokuti vamwe masayendisiti vanogutsikana kuti mwana ane vabereki vane utete, mukana wekuve wakachena kune wakakura kune wevamwe vana. Saka, zvinokosha kuverenga BMI mukuzvitakura kana kuronga mwana. Tsanangudzo yeBMI yevakadzi vane pamuviri inobatsira kuziva kuti huwandu hunorevei hwevakadzi hunogona kuwana mumwedzi gumi nemashanu. Iine BMI inosvika makumi maviri, vanachiremba vanokurudzira kuwana 13 - 13 kg panguva yekuzvitakura, kana mutumbi mairi index panguva yekuzvitakura kwaiva 20-27, uye panguva ino mukadzi anoda 10-14 kg, ane BMI inopfuura 27, mutoro unorema unofanira kuva . Asi, sezvo uri mune chinzvimbo chinonakidza, iwe unofungisisa nekuedza kuyerwa: panguva yekuzvitakura, haufaniri kurasa.
