Required resources
To undertake this test you will require:
- Measurement calipers
- Assistant.
Measurement sites
Take measurement from the following places:
1)
Triceps – with the arm resting comfortably at the side, take a vertical fold
parallel to the long axis of the arm midway between the shoulder and the tip of
the elbow.
2)
Subscapula – take a diagonal fold across the back, just below the shoulder blade.
3)
Biceps – with the arm resting comfortably at the side, take a vertical fold
halfway between the elbow and top of the shoulder on the front of the upper
arm.
4)
Suprailiac – take a diagonal fold following the natural line of the iliac crest,
just above the hip bone.
How to conduct the test
The method is as follows:
- Ensure that all of the skinfold measurements are located on the
right side of the body and that the measurements are taken in millimeters.
- Pick up the skinfold between the thumb and the index finger so as
to include two thickness of skin and subcutaneous fat.
- Apply the calipers about one centimeter from the fingers and at a
depth about equal to the thickness of the fold.
- Repeat the procedure three times as the measurement may vary and
record the average value.
- Add the results of each measurement to get a total value in
millimeters.
Analysis
Using the total value obtained from the four
measurements determine the percentage body fat from the table below:
