Purpose: Whole body three-dimensional scanning is a tool utilised for the collection of body girths, volume and surface area measurements. Few studies have investigated the validity and repeatability of this technology. The aim of the present study was to investigate the test re-test variability of the NX-16 body scanner (NX-16, TC2, Cary, North Carolina, USA).
Methods: Phase one involved the measurement of a mannequin on 300 occasions (30 scans over 10 sessions). In phase two, 13 apparently health male participants were recruited; each participant was scanned a total of four times (two scans over two sessions). Stature, body mass, and body fat % were obtained. Fourteen girth measurements were obtained (chest, underbust, stomach, waist, seat, hip, R/L bicep, R/L thigh, R/L mid-thigh and R/L calf). Coefficient of variation was calculated for measurements obtained.
Results: Coefficient of variation for phase one ranged from 0.0% for the R calf, to 3.3% for the L thigh measurement. For phase two, values were higher, ranging from 0.5% for calf and chest to 4.6% for thigh measurements.
Conclusions: Test-retest variability of the measurements provided by the NX-16 body scanner varied according to body location. However, variability within measurements was low using a mannequin or human participant. The NX-16 body scanner (TC2, Cary, North Carolina, USA) may be a useful tool for tracking changes in body composition over time during large population studies.
