今天是一周一次量體脂肪的日子,晚上很開心的跑去康是美;沒想到服務人員說體脂計壞了
那我還怎麼評估上個禮拜的運動成果勒??
急著找尋替代方案就找到這個app
http://ppt.cc/DlQt
需要用皮尺量腰圍跟頸圍還有身高計算出來 體脂肪率 19.74%
很好奇是依據什麼原理算出這樣的數值於是又找到了這個線上計算體脂肪率的網站
http://ppt.cc/N@Od
輸入相同的腰圍身高頸圍計算出來 居然只有18.9%
比對上周去康是美量測的結果27.3% 差了7%以上,這搞得我好亂阿!
不知道該相信康是美還是相信計算出來的結果
順便附上網頁上寫出來的計算公式
Males
percentage body fat = 86.010 * log10(abdomen-neck)- 70.041 * log10(height) +
36.76
Females
percentage body fat = 163.205 * log10(waist+hip-neck) - 97.684 *
log10(height)-78.387
希望板上的強者神人來指點一下迷津
