When we used underwater weighing
, which accurately measures body fat, we found that 200 mcg a day for eight weeks had no effect on the muscle, fat, or strength of football players," reports Priscilla Clarkson, a sports nutrition expert at the University of Massachusetts in Amherst.
Moreover, where deuterium oxide dilution requires drawing blood and underwater weighing
requires immersion in a calibrated pool, the infrared technique can be completed in three minutes and may ultimately require no more than the rolling up of one's sleeve.
Testing methods include the BOD POD, underwater weighing
, x-ray body scan, skinfold calipers, and bioelectrical impedance among others.
The most accurate test, underwater weighing
, is also the most cumbersome and thus is not available except in some hospitals and research labs.
The BOD POD replaces inaccurate skinfold calipers and the inconvenient underwater weighing
