The purpose of this study was to validate the percentage of body fat (%BF) values estimated from the BOD POD (BP) with those obtained from hydrostatic weighing (HW) in athletic American high school boys. Additionally, the %BF values measured via near-infrared interactance (NIR), bioelectrical impedance (BIA), and skinfold (SF) were compared to HW to determine the validity of these measures. Thirty white boys (mean age +/- SD = 15.8 +/- 1.0 years) who where currently participating in organized sports volunteered to have their %BF estimated. Measurements were obtained from NIR, BP, BIA, and SF in random order and concluded with HW. The findings from the present study indicated that the NIR and BIA instruments produced significant (P < 0.008) constant error (CE) and total error (TE) values that were too large to be of practical value (TE > 4.0%BF). The BP produced a significantly (P < 0.008) higher CE with acceptable TE values compared to HW, but compared to all three SF estimations, the BP TE values were higher. Two of the SF equations were nonsignificant (P > 0.008) and had the lowest TE values compared to HW. These data suggest that the BP can produce acceptable body fat measures for athletic white boys but is not superior to estimates made by the SF equations used in this study.
本研究的目的是验证美国高中体育生通过BOD POD（BP）估算的体脂百分比（%BF）值与水下称重（HW）所得值之间的差异。此外，还将通过近红外交互作用法（NIR）、生物电阻抗法（BIA）和皮褶厚度法（SF）测得的%BF值与HW进行比较，以确定这些测量方法的有效性。30名目前正在参加有组织体育运动的白人男孩（平均年龄±标准差=15.8±1.0岁）自愿参与估算其%BF。测量按照随机顺序通过NIR、BP、BIA和SF进行，最后进行HW测量。本研究结果表明，NIR和BIA仪器产生了显著（P<0.008）的恒定误差（CE）和总误差（TE）值，其误差过大以至于没有实际价值（TE>4.0%BF）。与HW相比，BP产生的CE显著更高（P<0.008），但其TE值在可接受范围内，但与所有三种SF估算方法相比，BP的TE值更高。其中两个SF方程不显著（P>0.008），与HW相比，其TE值最低。这些数据表明，BP可以为体育生白人男孩提供可接受的体脂测量值，但并不优于本研究中使用的SF方程所做的估算。
