Bod Pod Measurements

Post by WickStick » Thu Aug 01, 2013 10:08 am

Hi all,

Anyone have a guess on how accurate these things are? More specifically, do folks here use these regularly or semi regularly to track their progress?

Just by doing a quick pubmed http://www.ncbi.nlm.nih.gov/pubmed/?ter ... d+validity search it seems that folks are trying to find the correct parameters for different ages, ethnicities, and even activity levels.

I ask mainly because a month ago I was bod podded at the university I work at, and it spit some numbers at me. It said I was 188 lbs, 12.3% BF, a density of 1.07g/cm^3 (this is why I can't swim...I sink), and a RMR of 1961 (sounds about right I imagine, although "sedentary" calculations but me at 2432, which is a bit high for sitting and typing I feel). So I want to get a sense of when I go in next time (since then, I have been training for a sprint triathlon), what kind of variability to expect. What kind of variability have you experienced using this? Based on the references below, I should expect the readings next time to be a fair reflection of any progress I make...

References for chewing on: (I am just going to assume ADP means bod pod, correct me if I am wrong)

http://www.ncbi.nlm.nih.gov/pubmed/18978611" onclick="window.open(this.href);return false; shows that Bod Pod over estimates body fat % in college atheletes compared to hydrostatic weighing

http://www.ncbi.nlm.nih.gov/pubmed/15064602" onclick="window.open(this.href);return false; seems to show no difference in college women athletes between dual energy x ray absorptiometry and bod podding

http://www.ncbi.nlm.nih.gov/pubmed/16888466" onclick="window.open(this.href);return false; suggests bod pod is reliable in a large heterogenous sample

it's more accurate than calipers, but considerably less accurate than hydrostatic measuring.

No one here uses one to track their progress. In fact the general consensus around here is that there's little value to knowing your bodyfat %, and for once I actually agree with the masses.

Knowing you bf % does very little in terms of practical application. The mirror and how your clothes fit is perfectly adequate in my opinion. I mean think about it, no matter what the bod pod or whatever tells you your bf% is, if you don't like how ripped you look in the mirror you'll keep cutting regardless. Different people look different at different bodyfat levels, so knowing the exact number makes very little difference.

I use waist measurement to tell me when I.m getting too fat.

that's just all those steroids you've been abusing causing intestinal growth.

You need to slow down Stu, you're not as young as you once were.
