Ukuhlaziywa kwe-impedance ye-bioelectrical (BIA) kuyindlela yokulinganisa ukwakheka komzimba ngokulingana nesilinganiso lapho umbane kagesi uhamba kuwo wonke umzimba. Amafutha omzimba (izicubu ze-adipose) idala ukumelana okukhulu (impedance) kunomzimba ongenawo amafutha futhi unciphisa izinga lapho uhamba khona manje. Izilinganiso ze-BIA zilinganisela amaphesenti amafutha omzimba usebenzisa ukuhlaziywa kwe-impedance ye-bioelectrical.
Kuyini Ukuhlaziywa Kweminyango Yomzimba?
Kungenzeka ukuthi ubonile izilinganiso zomzimba emashalafini esitolo noma ku-intanethi esebenzisa ukuhlaziywa kwe-impedance ye-bioelectrical. Njengoba izikali zingabiza, mhlawumbe uzibuze ukuthi ukuhlaziywa kwemithi ye-impedance yezinto eziphilayo kubaluleke kangakanani futhi kufanele ukukhokhele?
Incazelo yokuhlaziywa kwe-impedance ye-b imisindo izwakala kahle. Kodwa izilinganiso ze-BIA zisebenzisa ubuchwepheshe obuqondile. Izikali zilinganisa izinga lapho umthamo wamandla kagesi ongenabuhlungu uhamba ngayo emzimbeni wakho. Ngokususelwa kuleso isilinganiso, isibalo sisetshenziselwa ukulinganisa ama-mass and fat fat body.
Kunezinhlobo ezahlukene zamadivayisi we-BIA . Amaningi amaningi omzimba omzimba ahlaziywa yi-impedance ye-bioelectrical impedance. Lokhu kusho ukuthi uma usebenzisa idivaysi, ubeka unyawo ngalunye kudatha futhi okwamanje uhamba ngomzimba wakho phakathi kwezinyawo zakho. Kodwa kukhona amadivaysi e-BIA okuhamba ngezinyawo, ngesandla ngesandla nangesandla-kuya-ngesandla, futhi.
Ingabe Ukuhlaziywa Kweminyango Yomzimba (BIA) Isilinganiso Esifanele?
Ezinye izifundo zibonise ukuthi ukuhlaziywa kwe-impedance ye-bioelectrical kuyindlela enembile yokulinganisa amafutha omzimba. Kodwa lezi zifundo zocwaningo ngokuvamile azihlolisi izilinganiso ozithola esitolo. Futhi ochwepheshe ngokuvamile bayavuma ukuthi ukunemba kwesilinganiso kuncike, ngokwengxenye, ngekhwalithi yedivayisi.
Ngaphezu kwalokho, kunezinye izici ezingathinta ukufunda uma usebenzisa isilinganiso se-BIA.
- Isisindo somzimba. Ucwaningo luye lwabonisa ukuthi ukuhlaziywa kwe-impedance ye-bioelectrical kungase kunembile kakhulu kubantu abakhulu kakhulu.
- Izinga lokunyakaza. Ezinye izifundo ziye zathola ukuthi ukungcola amandla kungabangela ukukhululeka kwamafutha (muscle kanye nethambo) ukuthi kungancishiswa.
- Umsebenzi wokuvivinya wakamuva. Ukuzivocavoca kakhulu kungathinta ukunemba kokufundwa kwe-BIA
- Umthwalo wokuqeqesha. Ezinye izilinganiso zinezilungiselelo ezikhethekile zabagijimi abaqeqesha kaningi. Izilungiselelo zenzelwe ukwandisa ukunemba.
- Ukudla okusheshayo noma ukuphuza ukuphuza. Imiphumela yocwaningo oluthile lisikisela ukuthi i-BIA inembile kakhulu ngemva kokuzila ukudla ebusuku.
Abanye abacwaningi bathi futhi ubuhlanga kanye nemvelo (njengokufana nokushisa kwesikhumba) kungathinta ukunemba kwezingqinamba ze-BIA.
Ingabe Kufanele Uthenge I-BIA Body Fat Scale?
Ngisho noma uthola ukufundwa okunembile ngesilinganiso se-BIA, inani limelela ukulinganisa kwamaphesenti amafutha omzimba wakho wonke. Ukuhlaziywa kwe-impedance ye-bioelectrical akuhlinzeki ngokulinganisa okuqondile kwamafutha omzimba wakho wonke . Isikali angeke sikwazi ukukutshela ukuthi ukhona amafutha emzimbeni wakho .
Ngabe kufanelekile ukuthenga isixazululo esisebenzisa impedance ye-bioelectrical? Kubantu abaningi, kungenzeka.
Ngisho noma kunezici eziningi ezingathinta ukunemba kokufunda kwakho, isikali se-BIA esisetshenziswe njalo singakubonisa izinguquko emanzini omzimba wakho ngokuhamba kwesikhathi . Ngakho-ke nakuba inombolo yangempela ingase ingaphelele, ungakwazi ukulandelela izinguquko ekubunjweni komzimba wakho ngokudla noma ukuzivocavoca .
Ukwengeza, uma usebenzisa umthamo wokuqina ngemikhiqizo efana ne-Fitbit, ungathola isilinganiselo ukubhangqa nedivaysi bese ulandelela wonke amethrikhi womzimba wakho endaweni eyodwa. I-Fitbit Aria 2 wi-fi smart scale esilinganisa isisindo, amanoni omzimba, nesikhombi somzimba womzimba. Izinombolo zivumelanisa ngokuzenzekelayo ngedeshibhodi ye-Fitbit ukuze ubone ukuthi izinombolo zithuthuka kanjani ngokuhamba kwesikhathi kanye nezinguquko zansuku zonke nezenzo zokudla.
Njengoba izilinganiso eziningi ze-BIA zinikela ngezici eziningana ngezindleko ezifanele futhi ngoba kuyindlela esheshayo futhi elula yokulinganisa amaphesenti omzimba womzimba, izilinganiso zomzimba womzimba ezisebenzisa ukuhlaziywa kwe-impedance ye-bioelectrical yi-investment efanelekayo kubathengi abaningi.
