Body Fat Jackson-Pollock 7-Site Caliper Calculator
Determine total body density and fat composition using the comprehensive 7-site Jackson-Pollock clinical caliper protocol.
Comprehensive 7-Site Caliper Analysis
The 7-site method assesses chest, midaxillary, triceps, subscapular, abdominal, suprailiac, and thigh skinfolds to capture whole-body adipose distribution.
Frequently Asked Questions
Why is the 7-site protocol preferred over 3 sites?
Capturing both upper and lower body sites accounts for individualized fat storage patterns, minimizing anatomical sampling bias.
How are body density and fat percentage converted?
Body density is converted to relative body fat percentage using the standard Siri or Brozek clinical equations.
Can skinfold calipers test visceral fat?
No. Calipers directly measure subcutaneous adipose tissue; visceral fat surrounding organs is derived indirectly via statistical regressions.
Should skinfolds be measured after intense training?
No. Exercise-induced hyperemia and dehydration alter subcutaneous tissue thickness. Measure skinfolds while well-hydrated and rested.
