Jackson-Pollock 7-Site Body Fat Formula (Women)
$$\text{Body Density} = 1.097 – 0.00046971 \cdot S + 0.00000056 \cdot S^2 – 0.00012828 \cdot A$$
$$\text{Body Fat \%} = \left( \frac{495}{\text{Body Density}} \right) – 450$$
Where:
- $$S$$ = sum of 7 skinfolds (mm)
- $$A$$ = age (years)
The Jackson-Pollock 7-point method for women uses caliper readings from the following areas: triceps, suprailiac, thigh, chest, midaxillary, subscapular, and abdominal.
It estimates:
- Body Fat Percentage
- Lean Body Mass (total weight minus fat mass)
This method is popular in fitness and health assessments and gives a solid estimate of body composition when measurements are performed correctly.
