Slaughter.2sites {bodycomp}R Documentation

Percent Body Fat Estimates Using Slaughter et al. (1988).

Description

This function calculates the percent body mass estimates based on 2 sites skinfold measurements using the equations of Slaughter et al. (1988). Population Specifications: Both sexes. Boys (aged 8 - 18) and Girls (aged 8 - 18)

Usage

Slaughter.2sites(Sex, TR, CA)

Arguments

Sex

a value or a vector representing the sex declared by the subject. Two possible choices: 0 or 1.

TR

a value or a vector representing Triceps Skinfold measurements. Direction of Fold: Vertical (midline). Anatomical Reference: Acromial process of scapula and olecranon process of ulna. Measurement: Using a tape measure, distance between lateral projection of acromial process and inferior margin of olecranon process is measured on lateral aspect of arm with elbow flexed 90°. Midpoint is marked on lateral side of arm. Fold is lifted 1 cm above marked line on posterior aspect of arm. Caliper is applied at marked level.

CA

a value or a vector representing Calf Skinfold measurements. Direction of Fold: Vertical (medial aspect). Anatomical Reference: Maximal calf circumference. Measurement: Fold is lifted at level of maximal calf circumference on medial aspect of calf with knee and hip flexed to 90°.

Details

Sex: Use 0 for Male and 1 for Female.

Value

Returns a data frame with the values of the % body fat from a subject assessed by skinfold measurements
