Malunga nale khadi
The U.S. Army body fat calculator uses the AR 600-9 circumference (tape) method to estimate body-fat percentage from height and a few measurements. Men use abdomen minus neck; women use waist plus hip minus neck. It also compares the result against the Army maximum allowable body fat for your age and sex.
The formula works on the logarithm of a circumference difference. For a man 70 in tall with a 34 in abdomen and 16 in neck, %BF = 86.010 × log10(34 − 16) − 70.041 × log10(70) + 36.76 ≈ 15.5%. Against the maximum of 22% for a soldier aged 21–27, that is within standard. Women use %BF = 163.205 × log10(waist + hip − neck) − 97.684 × log10(height) − 78.387, with every measurement in inches.
The maximum allowable body fat rises with age — for men 20% at 17–20 up to 26% at 40+, and for women 30% up to 36% across the same bands — and the tool flags whether you pass. Measure the abdomen at the navel and the neck just below the larynx; women add the hips at their widest. The tape method is a practical screen, not a lab-grade measurement like DEXA, and this tool is for reference, not official assessment.
Imibuzo ebuzwa kaningi
Yini i-AR 600-9 formula?
Kumadoda, %BF = 86.010 × log10(ikhanda − ikhanda) − 70.041 × log10(ubude) + 36.76. Kubesifazane, %BF = 163.205 × log10(ikhanda + ikhanda − ikhanda) − 97.684 × log10(ubude) − 78.387, zonke izibalo ziyi-intshi.
Yini isilinganiso esiphezulu sokudla okuvunyelwe iSikhulu sezoMkhosi?
Ikhula ngobudala. Abantu abaneminyaka engu-18 kuya ku-64 bathola i-20% (17-20), 22% (21-27), 24% (28-39) kanye ne-26% (40+); abantu abaneminyaka engu-65 kuya ku-69 bathola i-30%, 32%, 34% kanye ne-36% phakathi kwezibandla ezifanayo.
Uyini umehluko phakathi kwalokhu nohlelo lweNavy?
Zonke zisebenzisa ukuhlolwa kwetheyiphu, kodwa izimo zihlukile futhi i-Army iqhathaniswa nemiphumela yakho nezidingo zomsebenzi we-body-composition. Akunakuphikiswa ukuthi i-lab method ishintsha njenge-DEXA ukuze kube lula.
Yini i-Army tape test?
Ilinganisela isisindo sesikhumba kusuka kumathebhu ambalwa okuhlola endaweni ye-calipers noma isilinganiso. Abantu balinganisela ikhanda ne-abdomen; abesifazane balinganisela ikhanda, i-waistline ne-hip, konke nge-intshi, futhi i-AR 600-9 formula iguqula labo babe yingxenye yesisindo sesikhumba.
Ngizoyidlula kanjani imithetho yobude besikhumba?
Ushukela wegazi olinganiselwa kufanele ube ngaphansi noma ngaphansi kwesilinganiso esiphezulu sobudala bakho kanye nobulili — isibonelo, 22% kumuntu oneminyaka engu-21-27. I-calculator ikhombisa ukuthi i-ergebnisse yakho ingaphansi kwelimi.
Ngawaphi amanani afanele?
Abantu balinganisela i-abdomen e-navel nase-neck ngaphansi kwe-laryng; abesifazane balinganisela i-natural waist engxenyeni encane kakhulu, ama-hips engxenyeni ebanzi kakhulu, ne-neck. Isilinganiso sokuphindaphinda nokujikeleza njengoba kucacisiwe.
Ingabe indlela yetheyiphu ilungile?
Isibonelo, uma uthola ukuthi ushukela wegazi wakho uphakeme kakhulu, udokotela wakho angakutshela ukuthi ushukela wegazi wakho uphakeme kakhulu. Isibonelo, uma ushukela wegazi wakho uphakeme kakhulu, udokotela wakho angakutshela ukuthi ushukela wegazi wakho uphakeme kakhulu.
