I-Calculator ye-Lean Body Mass
Ubalo ubunzima bomzimba obusezantsi kunye nobunzima benyama emnyama usebenzisa ifomula yeBoer.

Malunga nale Calculator
A lean body mass (LBM) calculator estimates the weight of everything in your body that is not fat — muscle, bone, organs and water — from your height, weight and sex. It uses the Boer formula by default, a well-validated prediction equation, with James and Hume as alternatives, and reports the remaining fat mass and body-fat percentage alongside it.
For a 175 cm, 75 kg man the Boer formula is 0.407 × 75 + 0.267 × 175 − 19.2 ≈ 58 kg of lean mass. Fat mass is then 75 − 58 = 17 kg, or about 23% body fat. Women use different constants (0.252 × weight + 0.473 × height − 48.3) because they carry proportionally more essential fat. The tool clamps results so lean mass never exceeds total weight.
Lean body mass is useful for setting protein and calorie targets, tracking whether a diet is costing you muscle, and, in medicine, for scaling some drug doses. Because these are prediction equations rather than a body scan, they are estimates — a DEXA scan or hydrostatic weighing is more precise for very lean or very heavy people. This is general information, not medical advice.
Imibuzo ebuza rhoqo
Yintoni ifomula yeBoer?
Kubafazi, i-LBM = 0.407 × ubunzima (kg) + 0.267 × ubude (cm) − 19.2; kubafazi, i-LBM = 0.252 × ubunzima + 0.473 × ubude − 48.3. Ibonisa ubunzima obuncinci obuvela kuphakamo nobunzima kwaye yenye yezo zinto zilula kakhulu ezichanekileyo.
Kutheni ubunzima bomzimba obuncinci bubalulekile?
Imisela ukutya kwakho okuphumlayo kunye nokusetyenziswa kweemveliso zezonyango, kwaye ukulandelela oku kukunceda uqinisekise ukuba ulahlekelwa ngumtliziyo kunokuba ulahlekelwa ngumqolo. Iiprotheyini kunye neentyatyambo zekalori zihlala zixhomekeke kwi-LBM kunokuba zixhomekeke kubunzima obupheleleyo.
Ingaba le nto ifana nepesenti yobude benyama?
Ziinxalenye ezimbini zenani elifanayo: ubunzima be-fat yisisindo sakho esingaphantsi kwesisindo se-lean body mass, kwaye iphesenti yobunzima be-fat ye-body yisisindo se-fat esihlukaniswe ngubunzima obupheleleyo. Isixhobo sibonisa zonke ezithathu.
Yintoni ubunzima bomzimba obuqhelekileyo obunobunzima obuncinci?
Izinga lixhomekeke kubungakanani kunye nobufazi, kodwa kumfazi oneminyaka engama-175 cm, 75 kg ifomula yaseBoer inika malunga ne-58 kg yesisindo esincinci kunye ne-17 kg yobunzima, malunga ne-23% yobunzima besikhumba. Amabhinqa anesixa esikhulu sobunzima, ngoko ke iphesenti yabo encinci iphantsi kubungakanani obufanayo.
Yintoni ifomula yobunzima bomzimba endingayisebenzisa?
I-Boer imiselwe kwaye iqinisekisiwe kakuhle kubafazi abaninzi; uJames noHume babonakaliswa ukuthelekiswa. Bavumelana ngokusondeleyo kwisakhiwo esiphakathi kwaye bahlukana kubafazi abancinci kakhulu okanye abakhulu kakhulu.
Ndiya kwenza ntoni ukuba ndikhule isisindo somzimba?
Ukuzilolonga okumelana nokuxinana okuneprotheyini eyaneleyo (ihlala i-1.6-2.2 g/kg) kunye nokutya okune-calorie eyaneleyo kukwakha imisipha, eyona nto iphambili eyenza ukuba ubunzima bomzimba bube buncinci. Ukulandelela i-LBM ngexesha lokuzila kunceda ukuqinisekisa ukuba ulahlekelwa ngumtliziyo kunokuba ulahlekelwa yimisipha.
Ingaba ubunzima bomzimba obusezantsi bufana nobunzima bamathambo?
Akukho nto. Ubunzima benyama obuncinci buquka imisipha kunye nethambo, iinwele, iinwele ezidityaniswe nesikhumba kunye namasuntswana egazi; imisipha yeskeleton inxalenye kuphela yalo. Imisipha yinxalenye esinokuyikhula ngayo ngokuziqeqesha.
