SFT measurement

Circumference measurement

Upper arm

Triceps—measured in the midline posteriorly over the triceps muscle at a point midway between the lateral projection of the acromion process of the scapula and the inferior margin of the olecranon process of the ulna.

Measured midway between the lateral projection of the acromion process of the scapula and the inferior margin of the olecranon process of the ulna

Thigh

Measured at the midline of the anterior aspect of the thigh, midway between the inguinal crease and the proximal boarder of the patella

Measured midway between the midpoint of the inguinal crease and the proximal border of the patella
