Today I had the privelage of finally using a dunk tank in ASU’s lab. I thought I would post my results.
At 207.25lbs I came in at 13.6% bodyfat. I had been guessing I was at 14% so I was pretty close. There are a few factors that could be influencing this though:
Lots to drink last night (But I drank a ton of water both last night and today so I should have been properly rehydrated)
I’m taking 1-ad which generally makes me hold onto to an additional 10lbs I don’t know where.
But overall the results seems to coinside with how I look.
Also this was done by my T.A. (doctoral student) so I think we can assume she knows what she is doing.
As a comparision I used calipers on myself afterwards (using three-site JP) and plugging my measurements into a population specific ACSM equation); I came out at right about 5% bodyfat. I asked my TA (who has a lot more practice than I do; since I’ve only used Accutrac calipers on myself) and her reading actually came in lower than mine on a few sites (We both measured 7mm on my chest; I measured 14 on my abdomen; she measured 10; and I measured 10 on my thigh and she measured 8). I didn’t plug it into the equations this time.
Also; looking online I plugged the numbers into a JP calculator;
for my readings I"m at 8.4 and for hers I’m a 6.5%. Wierd huh?
