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/?term=bod+pod+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...
