3-dimensional (3D) anthropometrics, such as volumes and surface area, have been shown to be important in predicting sport performance, and assessing health status, but most commercially available whole-body scanners are cost prohibitive. The main purpose of this study was to determine the test-retest reliability of a commercially available single camera 3D body scanning system to assess whole body and segmental circumferences, surface areas, and volumes of healthy collegiate athletes and students. Forty-nine male and female student-athletes active in various sports from a division I institute were scanned and measurements were analyzed. The single camera system demonstrated good within- and between-session reliability. Reliability was quantified as the systematic error, random error, and test-retest correlation. The Styku 3D whole body scanner demonstrated nearly perfect reliability. Systematic errors were negligible (mean standardized bias [95%CI]: within-session, 0.04 [0.02, 0.06]; between-session, 0.02 [0.01, 0.03]), random errors were negligible (mean standardized typical error [95%CI]); within-session, 0.14 [0.11, 0.17]; between-session, 0.09 [0.07, 0.13]), and test-retest correlations were nearly perfect (mean ICC [95%CI]: within-session, 0.98 [0.97, 0.99]; between-session, 0.99 [0.99, 1.00]). 3-D body scanning using a single camera system may be a good fit for professionals looking for a low-cost system for the evaluation of body shape and size.
