Measurement in Physical Education and Exercise Science
Anthropometry is important for predicting sport performance. While 3-dimensional (3D) body scanners increase the feasibility of anthropometric assessment, reliability data on athletes are lacking. The aim of this study was to determine the test-retest reliability of a portable, single-camera 3D body scanning system (Styku S100) to assess circumferences, and whole-body and segmental surface areas and volumes of athletes. Forty-nine (19 male) athletes were scanned six times (two sessions of three scans). The Styku scanner demonstrated nearly perfect reliability. Systematic errors were negligible (mean standardized bias [95%CI]: scan 1 vs. 4, 0.04 [0.02, 0.06]), random errors were negligible (mean standardized typical error [95%CI]): scan 1 vs. 4, 0.14 [0.10, 0.17]), and test-retest correlations were nearly perfect (mean intra-class correlation coefficient [95%CI]: scan 1 vs. 4, 0.98 [0.97, 0.99]). Single-camera 3D body scanning systems may provide practitioners and researchers with a feasible tool to evaluate body size and shape.
