Body Composition Testing

Assessing Body Composition
Metatest is proud to utilize the Futrex 6100A/ZL to assess your percentage of body fat.  This technology is the most convenient and accurate method for computing body composition on the market today.  With the Futrex 6100 we can achieve results that are as accurate and repeatable as Hydrostatic (or under water weighing) without all of the uncomfortable limitations involved in the hydrostatic test.   Consult the chart below to see that when you undergo underwater testing you have to be in a bathing suit, you cannot eat for at least 2 hours, you must go to the bathroom within 30 minutes of the test, you cannot workout for a reasonable period before the test and so on.  With the Futrex there are no such limitations.  As long as we can get access to the skin on your dominant for 10 seconds we can get an accurate measurement of your bodyfat.  This is just as accurate as Hydrostatic or caliper testing without all of the hassle or cost.  On the average, a Futrex test is up to ½ the price of the other methods.  You cannot know where you want your body to be without first knowing where you are right now.  With this test being so affordable, easy and accurate you cannot pass up the opportunity to start your workout planning without a realistic assessment of how your body is currently built.  This test will give you more knowledge about yourself in 10 minutes then you can possibly gain in a lifetime of working out a gym.  After your Body Composition Assessment, we will assist you in computing your recommended body weight.

Recommendations before arriving for body composition assessment:

  1. Wear short sleeved shirt.
  2. Make sure you are well hydrated before arriving for your assessment
  3. Please know your current HEIGHT & WEIGHT


What does Body Composition mean?

To begin to understand what body composition is we must first recognize that the human body consists of fat and nonfat components. The fat component is termed fat mass or percent body fat. The nonfat component is termed lean body mass.

Example Illustration
What are essential and storage fats?

The total fat in the human body is classified into two types: essential fat and storage fat. Essential fat is defined as the fat needed to maintain normal physiological functions. Essential fat is found in such tissues as muscles, nerve cells, bone marrow, intestines, heart, liver, and lungs. This essential fat constitutes about 3% of the total weight in men and 12% in women. The percentage of essential fat is higher in women as it includes sex-specific fat, such as breast tissue, and other sex-related fat deposits.
Storage fat is the fat which is stored in the adipose tissue, mostly beneath the skin (subcutaneous fat) and around the major organs in the body. The storage fat is used as an insulator to retain body heat and as an energy substrate for metabolism. It also serves as a form of protection against physical trauma to the body. Unlike essential fat, there is no real difference in the amount of storage fat between men and women. However, men tend to store fat around the waist while women more so around the hips and thighs.


Single Site Measurement -- How Does It Work?

Futrex offers the only method of measuring body fat that uses completely safe, Near-Infrared light to directly measure percent body fat. U.S. Government research located a single point on the human body - the center of the biceps of the dominant arm (the arm used to write) - that has a direct correlation with the body's overall fat level.
During operation, the Futrex Light Wand sends a safe, Near-Infrared light beam into the biceps of the dominant arm at specific wavelengths that fat will absorb and lean mass will reflect. The light absorption is measured to determine body fat -- it's that simple! Test results, which are traceable to underwater weighing, are instantly shown on the unit's easy-to-read LCD display, and are also printed out for your clients to take with them.
