Last week I got a shock. Volunteered for a study done by the Exercise Sciences Dept at the local Univ. Got a free DEXA scan. Surprise, surprise, as Gomer Pyle says.
My result, besides above avg bone density, was a fat percentage of 30+%. Scan was done by a student, then the PhD came in to explain the results. I was stunned and mute as he politely explained that I was past the overweight category and was borderline obese! Went in with the self image of an older athlete and weight lifter and came out confused.
Problem is, no way am I carrying around 60 lbs of fat! I mean, jeepers, that would be 29 quarts -- 7 gallons -- of fat!?
Pinching an inch on the lower abdomen does not equate to a 30% body fat percentage. Does it?
Does the DEXA software subtract out the weight of the bones and give only a fat/soft tissue ratio, which would mean significantly less fat than 60 lbs?
Are calibration errors possible? Likely for a shiny new state of the art exercise lab at a major univ?
Operator error? I do know one hand was off the scan field.
Is muscle tissue in those of us 60+ less dense? In endurance athletes?
Note. I am not massive but built more like a swimmer or triathlete, tho at 38" around the waist (45" chest, 42" hips), not slim. I mostly train low-weight high-rep resistance + cycling and hiking. Height 5'10", Wt. 204 lbs. BMI (for what that's worth) 29.
