Body Composition Analysis
We conduct an in-depth analysis to determine how your body’s muscle, fat, and water contributes to weight gain or weight loss and your ability to maintain good health. During a 30-minute appointment, we start by taking a 60-second, non-invasive assessment with the InBody 570, specialized equipment that acts like a scale and performs body composition analysis. An exercise physiologist will then review and interpret your results with you. You can schedule a follow-up personal training appointment to learn how to put the results to best use.
A body composition analysis is not recommended for people with medical implants like a pacemaker or defibrillator due to safety precautions with electronic implants. It’s also not recommended for people who are pregnant or menstruating because results may not be accurate due to changes in hydration and body water levels.
Why Understanding Body Composition Matters
Unlike a traditional scale, which only measures your overall weight, a body composition analysis explains what’s behind that number. It can make a difference in how you manage weight, and offer a roadmap for making progress toward wellness goals. Each time you have a test, we’ll explain changes to your body’s makeup of muscle, fat, and water and what they mean. Tracking measurements multiple times allows us to guide changes in your wellness routine along the way.
How to Prepare for a Body Composition Analysis
24 hours before your appointment
Hydrate well; consume at least 64 ounces of water.
Do not drink alcohol.
Avoid exercising six to 12 hours before your test.
The day of your appointment
Avoid eating three to four hours before your test.
Do not consume caffeine.
Do not shower or use the sauna immediately before your test.
Do not apply lotion or ointment to your hands or feet.
When you arrive for your appointment
Use the restroom prior to testing.
Remove all jewelry, socks, pantyhose, and shoes.
Stand upright for at least five minutes prior to testing. You can stand still or walk at a slow pace.
If testing in the winter, it’s best for your body to be warmed up with light walking or movement up to 20 minutes before your test. Mild or rigorous exercise immediately before your test is not ideal and may skew results.
Whether you're starting an exercise program for the first time, or you’re getting back into the routine, our fitness assessments can help. We evaluate your wellness, establish a baseline, and help you set goals based on your current fitness levels. During your assessment, we review your medical history and determine which of these tests will help establish baseline measurements we can improve upon:
Once we have your results, you can choose to make a follow-up appointment with one of our exercise physiologists to create a personalized fitness program that suits your needs, experience, expectations, and what you enjoy. This is follow-up appointment is considered a personal training session and will be a separate cost from your fitness assessment.
Fitness assessments are appointment-only and made by calling the Duke Health & Fitness Center at 919-660-6660 or emailing DukeHealthandFitnessCenter@duke.edu. If you would like to track your progress, a second assessment can provide feedback at a later date.
