I have a Tanita Body Fat scale which uses bioelectrical impedence to determine BF% , and it has different settings for gender, age, etc. It even has a different setting for athletes. I actually fit into their “athlete” category because I train at least ten hours per week, at the gym and on the tennis courts. For experimentations’sake, I measured my BF at several different settings (female, male, athlete, non-athlete) and got VERY different results. I have three questions:
Does anybody know what the various settings “tell” the machine in order to alter the results?
Are these machines accurate and/or to be believed at all? (I’ve also read that bodybuilders and hardcore athletes will not get accurate readings from such devices.)
Is there an accessible method out there that IS accurate?
