Sign up for your pre-challenge scan!

We are excited for the upcoming Fall Nutrition Challenge.  We will be releasing more information over the next week, but first and foremost we need all participants to schedule their pre-challenge DEXA scan.  This scan will measure your body composition (including bone density), which will be used to assess change over the 6-week challenge, as well as help determine the amount of protein you should be eating at every meal!

The $50 cost of participating in the challenge includes the pre and post DEXA scans, which is one heck of a deal!  The challenge runs for six weeks from October 11th to November 22nd.

Important Information

If you have had any of the following you may NOT want to participate in the DEXA body composition assessment or may want to seek additional information:

-DEXA test within the last (1) year

-Multiple/frequent x-rays (dental, chest, broken bone, etc.)

-Multiple/frequent other medical procedures in which you have been exposed to x-rays or radiation (e.g. some CT scans and MRI’s, some types of tumor/cancer treatment)

You can skip the DEXA assessment and still participate in the challenge; the other assessment measures will be included and monitored if you need to skip the DEXA scan.

All body composition assessments will be performed at Corbett on the University of Wyoming Campus in Rooms 206 and 208:  Across Grand from the EAST Box and 1 block to the northwest (dark brown brick building with construction going on to the North).  Enter using North or East doors.

Females:  A pregnancy test by urine sample (dip test) with a negative result is required to receive a DEXA scan. This test will be done at the time of DEXA scan.

What the Dex is a DEXA Scan?

We consider DEXA (Dual X-ray absorptiometry) to be the best body composition technique available. You lie down on an open “table” for aproximately 8 minutes while your body is scanned, it’s painless and extremely accurate, and it measures regional (arms, trunk, and legs) as well as total body % fat, fat mass, bone mass, and lean mass. This regional, three compartment analysis is superior not only for an initial assessment, but also for tracking change. For example, with a weight training program the total increase in muscle mass and the increase in muscle mass in the arms, trunk, and legs can be determined.


A DXA scanner is a machine that produces 2 X-ray beams, each with different energy levels. One beam is high energy while the other is low energy. The amount of X-rays that pass through the bone is measured for each beam. This will vary depending on the thickness of the bone. Based on the difference between the two beams, the bone density can be measured.

Why is body composition important?
Body composition is very important for overall health and for athletic performance. An excessive amount of body fat is a risk factor for heart disease, type II diabetes, and other diseases. At the same time, having too little body fat can be detrimental to your health. For many athletes performance is improved with optimal body composition.Click here for % body fat standards.
