Abstract

Background: The accuracy of body composition assessments with bioelectrical impedance (BIA) based devices may be affected, besides the well-known factors (e.g. hydration status), by factors which are related to anthropometric characteristics.

Aim: The aim of this study was to investigate the effects of somatotype on body composition estimation, especially on lean body mass (LBM), using BIA.

Methods: 539 male (mean age: 15.8 ± 2.5 years) and 121 female young athletes (mean age: 16.5 ± 3.2 years) were included. Body composition was assessed by BIA and dual-energy X-ray absorptiometry (DXA). Somatotype was determined using the Heath-Carter method (endomorphy, mesomorphy, and ectomorphy). Intergroup differences were analysed with one-way and repeated measures analysis of variance.

Results: On average, BIA underestimated percent body fat (PBF) by 7.6% and overestimated LBM by 3.9 kg compared to DXA. Significantly smaller bias between the two methods was found in mesomorphy for both LBM and PBF. The ectomorph group demonstrated the largest underestimation in PBF, while the endomorph group the largest overestimation in LBM. Segmental analysis revealed larger overestimation of LBM of the lower limbs in ectomorphy.

Conclusions: Findings suggest that LBM estimates are affected by somatotype with mesomorphy reducing, while ectomorphy and endomorphy increase, the estimation bias between BIA and DXA.

体格类型影响用生物电阻抗分析估计年轻运动员的瘦体重。

背景：除了众所周知的因素（如水合状态）外，基于生物电阻抗（BIA）装置的身体成分评估的准确性可能会受到与人体测量特征相关的因素的影响。目的：本研究的目的是探讨身体类型对身体成分估计的影响，特别是对瘦体重（LBM）的影响。方法：男性539例（平均年龄15.8±2.5岁），女性121例（平均年龄16.5±3.2岁）。采用BIA和双能x线吸收仪（DXA）评估体成分。采用Heath-Carter法测定体型（内胚、中胚和外胚）。组间差异分析采用单因素和重复测量方差分析。结果：与DXA相比，BIA平均低估了7.6%的体脂百分比（PBF），高估了3.9 kg的体重。两种方法之间的偏差在LBM和PBF的中形态中都被发现明显较小。外形态组对PBF的低估最大，而内形态组对LBM的高估最大。节段分析显示，畸形患者对下肢LBM有较大的高估。结论：研究结果表明，体型对LBM的估计有影响，中形态减少，外形态和内形态增加，BIA和DXA的估计偏差较大。
