Standardized Measurement Procedures Phase II: Validation of Measurements Marine Corps Test (MPGl-Pl, Phase 2).

This project had three primary goals to examine the relationship between human body measurements taken with measuring tapes and those extracted from whole body scans with ARNScan software to examine an approach to garment size selection based on multivariate analysis of dimensions extracted from whole body scans and to examine anthropometric changes in Marine Corps recruits during the course of basic training. We used recruits processed at the Marine Corps Recruit Depot - San Diego as test subjects. The recruits were scanned by a Cyberware WB4 whole body scanner, and measurements were extracted using ARNScan software. We compared a series of software-extracted measurements to traditional measurements taken with a tape. The mean differences, those averaged over all individuals, ranged from 6 mm .25 inch on neck circumference to 66 mm 2.6 inches on sleeve length. Finally, we examined anthropometric changes which occur in association with Marine Corps basic training. Many recruits lost weight, but the biggest changes were reductions in a number of torso circumferences, indicating a loss of body fat, and relative increase in muscle. Over 95 of recruits experienced some change in body dimensions, and many of these changes were larger than the garment grade in dress clothing.
