I-Calculator ye-Lean Body Mass
Linganisa isisindo sakho somuntu esincane kanye nesisindo se-fat usebenzisa i-Boer formula.
Iziphetho zivuselelwa uma ubhala.
Malunga nale khadi
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 ebuzwa kaningi
Yini ifomu le-Boer?
Kumadoda, LBM = 0.407 × ubunzima (kg) + 0.267 × ubude (cm) - 19.2; kwabesifazane, LBM = 0.252 × ubunzima + 0.473 × ubude - 48.3. Ibikezela ubunzima obuncane kusuka ubude nobunzima futhi iyinye ye-equations elula kakhulu efanelekayo.
Kungani isisindo somzimba esincane sibalulekile?
Ibeka i-metabolism yakho ephumula kanye nemithi-dosing emithi, futhi ukulandelela isiza ukuqinisekiswa ukuthi ulahlekelwa i-fat hhayi i-muscle. Amaprotheni nama-calorie a targets avame ukusekelwe ku-LBM hhayi ubunzima obuphelele.
Ingabe lokhu kufana nephesenti lesisindo somzimba?
Ziyingxenye ezimbili zenombolo efanayo: isisindo se-fat siyisisindo sakho esincane kunesisindo se-lean body, futhi isisindo se-fat siyisisindo se-fat esihlukaniswe ngesisindo esiphelele. Ithuluzi libonisa zonke ezintathu.
Yini isisindo somzimba esijwayelekile?
Izinga lobukhulu nobulili, kodwa kumuntu oneminyaka engu-175 cm, 75 kg, ifomu leBoer linikeza cishe ama-58 kg wesisindo esincane kanye ne-17 kg ye-fat, cishe ama-23% wesisindo esincane. Abesifazane bathatha ama-fat abalulekile, ngakho-ke isilinganiso sabo esincane siphansi kuleyo ngxenye.
Ifomu elinjani le-lean-mass kufanele ngisebenzise?
I-Boer iyiphutha futhi iqinisekisiwe kahle kubantu abadala abaningi; uJames noHume babonisana ngokuqhathaniswa. Bavumelana ngokuqinile ngemiphakathi yokwakha futhi bahlukana nge-lean kakhulu noma abantu abanzima kakhulu.
Ngizoyithuthukisa kanjani isisindo somzimba?
Ukuzivikela uqeqesho nge-protini eyaneleyo (okusho ukuthi 1.6-2.2 g / kg) kanye ne-calorie egcwele efanele ithuthukisa amathambo, ingxenye eyinhloko yesisindo esincane. Ukulandelela i-LBM ngesikhathi sokudla kusiza ukuqinisekiswa ukuthi ulahlekelwa i-fat hhayi amathambo.
Ingabe isisindo somzimba esincane sifana nesisindo semisipha?
Akunalutho. Isisindo esincane sifaka amathambo kanye nethambo, ama-organs, ama-connective tissues kanye nama-water body; amathambo eskeletal ayizingxenye kuphela. Amathambo yingxenye ongayikhula ngayo ngoqeqesho.
