電子磅出既脂肪率就係正確嗎?

- 人地咁大間公司出得既就應該正確既. 計算脂肪率係利用電流流入身體, 電阻既大小去計算, 因為脂肪會導電既肌肉就唔會. 呢種科技應用左好多年, 咁除非佢地有心欺騙消費者啦, 如果唔係準確度好高.
- 係全身既脂肪率. Body fat % 係計全身既. 話明係 "Body" fat.







Body Fat Rating Scale

Moderate
19-24%
26-29%

Overfat*
25%+
30%+

用脂肪夾都得, 不過普通人好難夾得準. 用既人員都要受過訓練先得, 唔係人人用得岩. 我上堂時用過, 我地度既同Lecturer 度既差好遠.
而且唔同既身體部位要用唔係既formula去計, 得到既唔會係%, 而只係一堆指數, indicate 你某個部位肥唔肥.

你可以試下就咁用量尺去量度身體某d部位, 再用算式得出大約既body fat. 愈量得多身體部位就愈準. 但當然, 始終人手度準確度有限.

Body Fat Calculator

Ther approximate body fat percentage (%) can be calulated according to the following formula.

Body Fat Percentage = (Body Fat Weight x 100) / total bodyweight
Body Fat Weight = Total bodyweight - Lean Body Mass
Lean Body Mass = A + B + E - C - D

Find the values of A, B, C, D, and E from the following:

For Women:
A = (Total body weight x 0.732) + 8.987
B = Wrist measurement (at fullest point) / 3.140
C = Waist measurement (at naval) x 0.157
D = Hip measurement (at fullest point) x 0.249
E = Forearm measurement (at fullest point) x 0.434

For Men:
Body Fat Formula For Men
A = (Total body weight x 1.082) + 94.42
C = Waist measurement x 4.15
B = D= E= 0

All measurements are in inches and weight in pounds.

脂肪夾唔係淨用黎夾手指, 身體部位包括手臀, 腰, 腿都可以用. (圖:http://hk.myblog.yahoo.com/silvia-diary/article?mid=177)而且夾手指只係去簡單量度肥唔肥, 並唔能夠顯示body fat %.

1.你用osim出個隻電子磅出既脂肪率就未必一定好準確,可能有小小唔岩
2.就應該唔係個個係平均既脂肪率
3.cheak到自己脂肪率未必一定要電子磅,有夾手指......
4.用夾住手指個個就應該得,我好似係”衣”院（同埋個個唔係夾脂肪,係夾手指等佢知道你有幾多脂肪)
5.係夾係手指到嫁
