Description
Summary:This paper reports the evaluation tests on the reliability and validity of a three-dimensional (3D) laser body scanner for the estimation of body volume and percent fat. Repeated measures of body imaging were performed for reproducibility analysis. The validity of the instrument was assessed by the comparison of the measures of body volume by imaging to hydrodensitometry, and body fat was compared to hydrodensitometry and dual energy X-ray absorptiometry. Reproducibility analysis showed little difference between within-subjects measurements of volume (intraclass correlation coefficient (ICC)≥0.99 and p
