  1. * Represents significance (p < 0.0125), Represents an unacceptable TE (TE > 4.0% BF)
  2. CE = Constant error, TE = Total error, SEE = Standard error of estimate, r = Pearson product-moment correlation coefficient.
  3. HW = Hydrostatic weighing [4], %fat = [(4.57/body density) - 4.142] × 100
  4. MC – Marine Corps [18], %fat = (0.740 × abdominal circumference in cm) - (1.249 × neck circumference in cm) + 0.985
  5. NAF – Navy and Air Force [21], % fat = [(4.95/body density) - 4.5] × 100
  6. NAF [20], body density = [0.155 × log (height in cm)] - [0.191 × log (abdominal - neck circumference in cm)] + 1.032
  7. Army [19], %fat = [76.5 × log (abdominal - neck circumference in cm)] - [68.7 × log (height in cm)] + 43.7
  8. Friedl [8], %fat = [0.771 × (abdominal - neck circumference in cm)] - (0.132 × height in cm) + 4.29
