Question

How to estimate the amount of muscle and fat in the mid upper arm by measuring the circumference of the upper arm and the thickness of a fold of skin on the back of the left upper arm (triceps skinfold)

Answer 1

Midarm Muscle Circumference is the measure of the mid upper arm circumference at the midpoint between the tip of the acromial process. It is measured to determine the upper arm muscle wasting. It is calculated by subtracting the triceps skin fold from the mid upper arm circumference measurement.
