Post subject:  body composition

I often use the skinfold calculator/body composition to find body fat percentile, lean weight, and fat weight. I recently did an experiment where I kept all of the parameters the same except for age. This produced much different results for all categories mentioned previously. Why would this happen?

The formulas assume a certain amount of body fat other than subcutaneous fat. This generally goes up with age. There is no non-destructive way to directly measure this fat with a caliper. The best way to measure this is with a tape measure around your waist.

Is there a test that, along with all of the components already put into the skinfold calculator, also ask for waist measurement and height? (Just trying to get the most accurate comparisons.)

I assume you've read this: http://www.exrx.net/Testing/BFTestComparisonStudy.html
This may help. http://www.ncbi.nlm.nih.gov/pubmed/17535865 There is a free text there. I didn't read it.
Here's another: http://www.nature.com/oby/journal/v13/n ... 0567a.html

This booklet tells you how to take measurements. http://www.cdc.gov/nchs/data/nhanes/nha ... anthro.pdf

If you find anything definative, let us know. I know I'm interested in it and I'm sure others are. I think the Nature article might prove to be the most useful.
