Abstract

Previous research in this laboratory, using relatively lean males, indicated that the skinfold caliper and ultrasound techniques gave similar predictions of body density. The present study compared caliper with ultrasound measurements in predicting body density of 44 white, obese, free-living adult volunteers of both sexes. Subcutaneous-fat thickness was measured at six body sites with a Lange caliper and an ADR 2130 ultrasound scanner. By hydrostatic weighing, mean (+/- SD) body density was 1.01 g/mL (+/- 0.02) and percentage body fat, 41.7% (+/- 7.8). The best predictors of body density were the thigh and biceps sites with ultrasound (r = 0.820) and the triceps site with the calipers (r = 0.633). Further, ultrasound proved to be superior to the caliper technique in measuring subcutaneous fat of obese persons.

摘要

本实验室之前使用相对偏瘦男性进行的研究表明，皮褶厚度计和超声技术对身体密度的预测结果相似。本研究比较了皮褶厚度计和超声测量法在预测44名自由生活的成年白种肥胖志愿者（男女皆有）身体密度方面的差异。使用兰格皮褶厚度计和ADR 2130超声扫描仪在六个身体部位测量皮下脂肪厚度。通过水下称重法，平均（±标准差）身体密度为1.01 g/mL（±0.02），体脂百分比为41.7%（±7.8）。超声测量大腿和肱二头肌部位对身体密度的预测效果最佳（r = 0.820），皮褶厚度计测量肱三头肌部位的预测效果最佳（r = 0.633）。此外，在测量肥胖者皮下脂肪方面，超声被证明优于皮褶厚度计技术。
