FUTREX 5000A
Benefit is I will be able to tell you what you need to do to increase your percentage of lean body mass or muscle and decrease your percentage of body fat to a healthy level. You may be surprised that by using this method you do not have as much weight to lose as you thought and how easily reachable your goal is. **************************************************************************

HAPPY NEW YEAR – BEST WISHES IN 20-10! Many of us have gone through the holidays packing a few pounds on due to gluttony i.e. too much turkey, ham and the sorts, or just laying around not burning off calories. After or even prior to the “New Year” we conjure up a “New Years Resolution” of getting into shape or loose those added pounds or added to your prior overweight pounds. This time is a good time for sports club membership purchases as there is that emotional and physical need to get in shape again for the coming swimsuit summer weather. We want to look good for that “fun in the sun” time. Getting into shape is hard work. You need to know if your work is paying off. In order to do so you need to create what is called a “Base-Line” weight comparison chart, which would include? · Total Percentage (%) Body Fat · Percentage of Body Fat · Fat Weight · Fat-Free Weight ( Lean Body Mass) · Total Body Water · Recommended Weight If you sports club does not have a body mass index calculator or a body composition and fitness analyzer come get your testing done at this office. If you are not a member of a club come anyway.
Why Measure Body Fat At All?
Percent body fat is known to be a key factor in determining fitness. It is also a known indicator of disease risk. Weight alone is not a reliable indicator of good health. Weight (pounds on the scale) does not distinguish between pounds that come from body fat and those that come from lean body mass or muscle. Carrying too much fat is what makes a person obese. Obesity is a known risk for many serious medical conditions including heart disease, diabetes and even certain forms of cancer. Obesity contributes to at least half the chronic diseases in western society.
Why Use Near Infrared Light?
NIR Quantitative Analysis was developed by the United States Department of Agriculture (USDA) in 1970. A simple non-destructive method of providing measurements of organic constituents was needed. The USDA discovered that when light is shined through any type of organic item, each item had its own, unique “glow.” The first NIR applications were agricultural, measuring sweetness in fruit, fat levels in ground beef, and protein levels in grain products. Futrex took the principles of NIR analysis, and adapted them for the measurement of percent body fat.
How Does The Futrex Measure Body Fat?
US government research determined that the biceps of the dominant arm has a direct correlation with overall body fat. Futrex’s technology uses Near-Infrared Interactance. This is the same technology used in the remote controls of modern TVs. Body fat absorbs these wavelengths of light and lean mass reflects them. The light absorption and reflection is measured to determine body fat.
What Does the Futrex “See” With NIR?
Fat - NIR light is absorbed by fat Subcutaneous fat Inter-muscular fat Lean Mass - NIR light is reflected by lean mass Muscle Bone Water
How & Why Does Futrex Work?
The FUTREX actually performs optical measurements. The Futrex Wand sends measured amounts of NIR light into the biceps of the dominant arm. Varying amount of light is absorbed or reflected, providing “optical density” values. Inputs them into a proprietary formula - (Multiple Linear Regression Analysis). Displays total body fat (TBF).
Why a Single Site Measurement?
USDA research found that the ratio of fat to lean mass is best represented in the inter/intra muscular region of the body. Three such locations were identified: Mid point of the Biceps Mid point of the Triceps Mid point of the Quadriceps Futrex chose the biceps for convenience
How Accurate is the Futrex?
Underwater Weighing is known as the “Gold Standard” of body fat measurement. Many people refer to it as the “dunk test.” All other methods, including Futrex, are calibrated to to this “reference laboratory.” Underwater Weighing has a Margin of Error of plus or minus 3%. Futrex has the same margin of error as Underwater Weighing.
What Is The F.I.T.?
The F.I.T. procedure provides a quantitative method to determine a subject's Physical Activity Rating. The F.I.T. value is a function of the following three parameters: Exercise Frequency - How often meaningful physical activity is performed Exercise Intensity - How much energy is expended during exercise Exercise Time - How many minutes the activity is performed during each session.
Refinements in research capabilities over the years have led to the realization that, contrary to initial assumptions, the percentages of water, mineral, and protein withen the Fate Free Body (FFB) differ based on age, ethnicity, activity, and health status. (1) .
The FIT helps to account for this. When entering the FIT values, you should consider what the individual's average Frequency, Intensity and Time have been over the past six months.
(1) All Measurements are not Created Equal, Ann L. Gibson, PH.D., Fitness Management, June 2006, p 52.
Asking the FIT questions
Frequency:
“On average, over the past six months, how many days per week do you exercise OR engage in meaningful physical activity?”
5 - Daily or almost daily (6 or 7 times per week)
4 - 3 to 5 times per week
3 - 1 or 2 times per week
2 - a few times per month
1 - no meaningful activity
Note: The frequency value should be evaluated independently of the intensity of the activity. For example, a person who walks in the evening every day will have a frequency rating of 5 even though the intensity of the activity will be low
Intensity:
“On average, over the past six months, what is the average intesity of your exercise OR meaningful physical activity?”
5 - Heavy Activity - Body Building, Running, Distance Cycling
4 - Moderately Heavy - Weight Training, Jogging Basketball
3 - Moderate - Speed Walking, Light Weight Training
2 - Light Moderate - Brisk Walking, Hiking, Golfing
1 - Light - Normal Walking, Gardening
Time:
“On average, over the past six months, what is the average time of your exercise OR meaningful physical activity?”
4 - Over 30 minutes
3 - 20 to 30 minutes
2 - 10 to 20 minutes
1 - Less than 10 minutes
How Does Futrex Compare to Other Methods?
All methods of body composition analysis are evaluated against the “Gold Standards” of Underwater Weighing or DEXA. All methods (BIA, skinfolds, FUTREX) have been shown to have accuracy similar to the “Gold Standards” in a clinical/research environment.
A major concern of researchers, however, is that the accuracy and repeatability can be affected by changing field conditions:
Skin fold calipers have been shown to have up to 9 percent variability from differences in skin fold technicians. (1)
Bio-Electrical Impedance requires the following pre-test protocols (2):
- No alcohol 48 hours before the test
- Avoid intense exercise 12 hours before the test
- Avoid eating or drinking (especially coffee, tea, and colas) 4 hours before the test
- Empty bladder 30 minutes before test
- Avoid all diuretics for 7 days before test (only if possible)
The NIR technology used by Futrex, eliminates theses concerns, making it both accurate and repeatable.
