Area you just want to kind of throw your shoulders back and just slide your fingers over the chest. And squeeze a fold of skin together. Off to the side either either the right side or the left side.
What are the three methods of determining body fat percentage?
JACKSON AND POLLOCK 3 SITE FORMULA TO CALCULATE BODY FAT
- Males.
- Females.
- Body density = 1.10938 – (0.0008267 x sum of skinfolds) + (0.0000016 x square of the sum of skinfolds) – (0.0002574 x age)
- Body Fat Percentage (%) = (495 / Body Density) – 450.
How is the skinfold test carried out?
Skinfold measurements are generally taken at specific sites on the right side of the body. The tester pinches the skin at the location site and pulls the fold of skin away from the underlying muscle so only the skin and fat tissue are being held.
IS 3 site skinfold accurate?
The overall BF% with the three-site formula (23.21 ± 3.61%) was significantly lower (t = −6.768, p < . 001, 95% CI [−3.30, −1.78], d = 1.069) than the seven-site formula (25.75 ± 4.39%) using the BodyMetrix™.
How do you calculate body density for a 3 site skinfold?
JACKSON-POLLOCK 3-SITE SKINFOLD FORMULA SPECIFICATION
- Men. BD = 1.10938 – 0.0008267(Y) + 0.0000016(Y2) – 0.0002574(Age) where Y= sum of Chest, Abdominal and Thigh skinfolds in mm.
- Women. BD=1.0994291 – 0.0009929(Z) + 0.0000023(Z2) – 0.0001392(Age) where Z = sum of Triceps, Thigh and Suprailliac skinfolds in mm.
Which of the following are the correct Pinch sites for a 3 site skinfold measurement on a man?
3-Site Skinfold Sites for Males
The pinch is taken between the nipple and the armpit (axilla) but closer to the armpit, approximately 1/3 the distance. The skin fold is a diagonal one in the direction of the nipple-armpit line.
How do you calculate body fat from skinfolds?
The Jackson and Pollock equation to calculate body density in women is: 1.0994921 – (0.0009929 x the sum of the skinfold sites in millimeters) + (0.0000023 x the sum squared) – (0.0001392 x age). For men, it’s: 1.10938 – (0.0008267 x sum) + (0.0000016 x sum squared) – (0.0002574 x age).
How do you use skinfold calipers?
But instead of doing the chest for women might turn around yep you're going to do the back of the tricep. So halfway in between the shoulder and the elbow. We'll take a vertical pinch.

Why do we measure Skinfolds?
The main purpose of skinfold measurements is to estimate general fatness and the distribution of subcutaneous adipose tissue. Fat is pinched between a two-pronged caliper on designated body sites such as triceps, biceps, abdomen, iliac crest, just below the scapula, the thigh and the chest.
