The Jackson and Pollock 7 equation is one of the most precise equations for calculating the percentage of body fat because it tests 7 skinfold sites and considers gender and age. It is ideal for people with moderate physical activity, the general population, and young athletes.
Body density = 1.112 – (0.00043499 x sum of all the skinfolds) + (0.00000055 x sum of all of skinfolds squared) – (0.00028826 x age)
Body Fat Percentage (%) = [(495 / Body Density) – 450] x 100
Body density= 1.097 – (0.00046971 x sum of all of skinfolds) + (0.00000056 x sum of all of skinfolds squared) – (0.00012828 x age)
Body Fat Percentage (%) = [(495 / Body Density) – 450] x 100
