Step One: Multiply your weight times 1.082. Step Two: Add 94.42 to this number. Step Three: Multiply your waste ( in inches ) times 4.15. Step Four: Subtract the result of step 3 from the result of step 2, this is your fat free body weight. Step Five: Subtract your fat free body weight from your total body weight. Step Six: Multiply the result of step five times 100. Step Seven: Divide the result of step six by your total body weight. This is your bodyfat percent. | ||

I think that number is the lean body mass percentage. to get the bodyfat %age, you need to subtract the final number from 100. | ||

i had mine tested the other day, he used calipers measuring 8 bodyparts (thighs,calfs,triceps,biceps, abs,axis??(central body point,back..), he did each area twice to get an average and gave my fat measurement in mm , it was 102mm of fat, he then had a book with a table which converted it to around 17% bodyfat. | ||

I had mine done in Physiology of Exercise class. We used calipers and measured for men: Upper outer part of the chest, lateral part of the thigh, and the lowest part of your abs. For women instead of the chest they measured their triceps. After that there was ALOT of calculations to be done. Its fairly accurate. But the most accurate is I forget the name of it but they weight you in a water tank, but its expensive to do. | ||

The scales you stand on can be very inaccurate too.. they tend to underestimate fat levels in obese people and overestimate fat levels in lean people. With the scales there is a low electrical current that is passed through the foot that travels through the whole body. The conductivity of muscle is higher than that of adipose(fat) or bone because of a higher electrolyte content. So the leaner you are, the less impedance there will be to the current. Then the scale estimates the bodyfat from that. The problem is, excessive water intake or dehydration can change the conductivity of the body. Making the estimation way off... The scales are expensive too sometimes. I think the best way to do it is just to use fat calipers or the good old mirror... Cheapest way too. Unless you have tons of money to blow on underwater bodyfat testing. | ||

when i got my test done i asked about the scales and he said with the electric scales the current only runs from your foot and up to the groin then back down the other leg, therefore only calculating the legs..pretty inaccurate. |
