BOD POD(®) self-testing (S/T) body composition tracking system is a practical assessment tool designed for use in the health and fitness industries. Relative to its parent counterpart, the BOD POD(®) S/T has received little research attention. The primary purpose was to determine the validity of the BOD POD(®) S/T against hydrostatic weighing and 7-site skinfolds. Secondary aim was to determine the within-day and between-day reliability of the BOD POD(®) S/T. After a period of equipment and testing accommodation, volunteer's (N=50) body composition (%BF) via 7-site skinfolds, BOD POD(®) S/T, and hydrostatic weighing were obtained on the second and third visits. BOD POD(®) S/T significantly overestimated %BF when compared to hydrostatic weighing and 7-site skinfolds. There was no statistical difference between 7-site skinfolds and hydrostatic weighing values. BOD POD(®) S/T reliability within-day and between-days were high. While the BOD POD(®) S/T body composition tracking system is deemed reliable both within-day and between-days, it did significantly overestimate %BF in comparison to hydrostatic weighing and skinfolds. Future research should be aimed at deriving a correction factor for this body composition assessment tool.
BOD POD(®) 自我测试 (S/T) 体成分跟踪系统是一款专为健康和健身行业设计的实用评估工具。与它的母体相比，BOD POD(®) S/T 受到的研究关注较少。主要目的是确定 BOD POD(®) S/T 与静水称重和 7 点皮褶相比的有效性。次要目的是确定 BOD POD(®) S/T 的日内和日间可靠性。在设备和测试适应期后，志愿者（N=50）的体成分（%BF）通过 7 点皮褶、BOD POD(®) S/T 和静水称重在第二次和第三次访问时获得。与静水称重和 7 点皮褶相比，BOD POD(®) S/T 显著高估了 %BF。7 点皮褶和静水称重值之间没有统计学差异。BOD POD(®) S/T 的日内和日间可靠性都很高。虽然 BOD POD(®) S/T 体成分跟踪系统在日内和日间都被认为是可靠的，但与静水称重和皮褶相比，它显著高估了 %BF。未来的研究应该旨在为这种体成分评估工具推导一个校正因子。
