Worked Step-by-Step Examples
Example 1: Male Army Body Fat Tape Test
"A 25-year-old male soldier with height 70 inches, neck 16 inches, and abdomen 34 inches."
Steps:
- Compute Abdomen minus Neck: 34 - 16 = 18 inches.
- Apply male formula: 86.010 × log10(18) - 70.041 × log10(70) + 36.76.
- Calculate logs: log10(18) ≈ 1.25527, log10(70) ≈ 1.84510.
- Evaluate expression: (86.010 × 1.25527) - (70.041 × 1.84510) + 36.76 ≈ 107.96 - 129.23 + 36.76 = 15.49%.
