Selecting the Measurement Site
Prior to conducting the actual body composition analysis, you should locate the proper measurement site at the biceps of the dominant arm.
1)Have the test subject hold his/her arm straight out, with the elbow locked, and the palm of the hand facing up towards the ceiling.
2)Using the Biceps Locator (shown below), find the “halfway point” between the armpit and the inside of the elbow, where the elbow bends (i.e. the acromion). As shown in the illustration, place the end marked “To Underarm” at the point marked “A.” The end marked “To Elbow” should extend past the bending point of the elbow towards point marked “B” in the illustration.
3)Once the Biceps locator is in place as described in step 2, identify the number on the Biceps Locator that crosses the point “C” on the arm. Point “C” is the place where the elbow bends.
4)Locate the corresponding number identified by point “D” in the illustration (e.g. if the number at point “C” is “6,” then find the corresponding “6” at point “D.”) This is the midpoint, or the “belly” of the biceps.
5)It is recommended that you mark this spot by placing a small line just to the inside or outside of the spot with a highlighter or washable marker.
