Bod Pod: Measuring Body Composition (Body Fat) at the Exercise Physiology Core Laboratory

October 27, 2019


Unfortunately, BMI, which is what most people use only gives the rough estimate of whether or not you’re really overweight or obese because people have different body types. We use the technique called the Bod Pod where we actually displace air to determine body density and from your body density we can fairly accurately determine what percentage of your body is fat The reason we have you wear compression tights or Speedo swimsuit is we don’t want any air trapped in the garments mass is important to the overall computation so this is an important step What I’m going to have you do is put a swim cap on and that’s again, it’s the same thing as the shorts, it’s because your hair traps air around it and it just helps compress everything down so we’re getting a more accurate volume I’ll have you sit exactly like this I’m going to close the door It takes about 50 seconds Try not to move, because the more you move the more the air will fluctuate in there We’ll do 2 of those And if those are in agreement, we’ll do a third with the hose The first 2 measurements are volume measurements so we’re strictly measuring the amount of air he displaces in the Bod Pod And the third measure will be to measure the air that moves in and out of his lungs as he’s breathing so we can subtract that out of his volume Once we get the volume, and we have his body weight we can calculate body density Once you have body density we can put that into prediction equations for percent fat and that’s based on different gender, age, and different race. With the Bod Pod we can use, in both the pediatric population, and we can go up to about 450 pounds. All right you doing okay? Not too strenuous, huh? Instructions from the computer will be, you’ll see a histogram to breathe in and breathe out It’s just having you breathe your normal breathing pattern And that’s all there is to it!

  1. I had my body fat tested at UVA Spring of 2012. I am 5"6" and weighed around 130 pounds. MY body fat was 38%!!! Obese. I did Crossfit and ate healthy so completely freaked out! Judy Weltman (who performed the Bodbod testing) was wonderful but baffled as well. After a year of searching WHY I had a normal BMI but obese, I found a homeopathic doctor tell me why. I had heavy metal poisoning and my fat cells were protecting me from the toxins causing my cells to be inflamed. Anyway, I followed the homeopathic doctors system and saw immediate changes.  I still weigh the same but much thinner through the waist where the fat had accumulated. I can tell you how I did it if you send me your info. Toxins are everywhere and they are making people (even thin people) have too much visceral fat.

  2. I had mine done recently and my weight is 181 pounds but on the digital scale I was weighting 200 pounds so which is more accurate. Also it had me 36 percent body fat which is considered obese but when I had my fat percentage done at the gym they had me at 26 percent body fat.

  3. Much talk about air being trapped. Does the body hair not matter (maybe more than on the head)?
