Body Fat %: Body Girth
Quickly measure and calculate your body fat%, lean body mass, and fat mass
Keep in mind that the comparison classifications vary by age and by gender, so it wouldn’t make sense to compare the body fat percentages of a 32 year old man vs a 32 year old woman, or a 32 year old woman vs a 65 year old woman. Skinfold measurements measure subcutaneous fat located under your skin and not visceral fat located within your abdomen. These metrics are best combined with circumference measurements and weight to create a complete picture of your health.
Body Girth Protocol
Purpose
Estimate of body fat % using circumference protocol. Commonly used by the United States Armed Forces.
Equipment
Tape measure
Procedure
Measurements sites remain the same over time. Measurements can be taken with the subject’s muscles relaxed or flexed depending on goals, preferences, programming, etc.
Male measurements:
- Waist: one inch above the navel or smallest circumference below the rib cage after complete expiration.
- Neck: circumference around the neck at a point below the larynx and perpendicular to the long axis of the neck.
Female measurements:
- Waist: one inch above the navel or smallest circumference below the rib cage after complete expiration.
- Neck: circumference around the neck at a point below the larynx and perpendicular to the long axis of the neck.
- Hip: largest circumference around the gluteals with subjects heels together.
