ABSTRACT

Anthropometry is important for predicting sports 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 males) athletes were scanned 6 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.

摘要

人体测量对于预测运动成绩很重要。虽然3维（3D）人体扫描仪增加了人体测量的可行性，但缺乏有关运动员的可靠性数据。这项研究的目的是确定便携式单相机3D身体扫描系统（Styku S100）的重测可靠性，以评估运动员的周长，全身和分段表面积以及体量。对四十九名（男19名）运动员进行了6次扫描（两次扫描，共3次扫描）。Styku扫描仪显示出近乎完美的可靠性。系统误差可忽略不计（平均标准化偏差[95％CI]：扫描1对4，0.04 [0.02，0.06]），随机误差可忽略不计（平均标准化典型误差[95％CI]：扫描1对4，4，0.14） [0.10，0.17]），测试和重新测试的相关性几乎完美（组内平均相关系数[95％CI]：扫描1对4，0.98 [0.97，0.99]）。单摄像机3D身体扫描系统可以为从业者和研究人员提供一种评估身体大小和形状的可行工具。
