Soccer referees are a specific group in the sports population that are receiving increasing attention from sports scientists. A lower fat mass percentage (FM%) is a useful parameter to monitor fitness status and aerobic performance, while being able to evaluate it with a simple and quick field-based method can allow a regular assessment. The aim of this study was to provide a specific profile for referees based on morphological and body composition features while comparing the accuracy of different skinfold-based equations in estimating FM% in a cohort of soccer referees. Forty-three elite international soccer referees (age 38.8 ± 3.6 years), who participated in the 2018 Russian World Cup, underwent body composition assessments with skinfold thickness and dual-energy X-ray absorptiometry (DXA). Six equations used to derive FM% from skinfold thickness were compared with DXA measurements. The percentage of body fat estimated using DXA was 18.2 ± 4.1%, whereas skinfold-based FM% assessed from the six formulas ranged between 11.0% ± 1.7% to 15.6% ± 2.4%. Among the six equations considered, the Faulkner's formula showed the highest correlation with FM% estimated by DXA (r = 0.77; R = 0.59 < 0.001). Additionally, a new skinfold-based equation was developed: FM% = 8.386 + (0.478 × iliac crest skinfold) + (0.395 × abdominal skinfold, r = 0.78; R = 0.61; standard error of the estimate (SEE) = 2.62 %; < 0.001). Due to these findings, national and international federations will now be able to perform regular body composition assessments using skinfold measurements.
足球裁判是体育人群中的一个特定群体，正受到体育科学家越来越多的关注。较低的体脂百分比（FM%）是监测健康状况和有氧能力的一个有用参数，而能够用一种简单快速的现场方法对其进行评估则可以实现定期评估。本研究的目的是根据形态学和身体成分特征为裁判提供一个特定概况，同时比较不同的基于皮褶厚度的公式在估计一组足球裁判的FM%时的准确性。43名参加2018年俄罗斯世界杯的精英国际足球裁判（年龄38.8±3.6岁）接受了皮褶厚度测量和双能X线吸收法（DXA）的身体成分评估。将六个用于从皮褶厚度推导FM%的公式与DXA测量结果进行了比较。使用DXA估计的体脂百分比为18.2±4.1%，而从六个公式评估的基于皮褶厚度的FM%在11.0%±1.7%至15.6%±2.4%之间。在所考虑的六个公式中，福克纳公式与DXA估计的FM%相关性最高（r = 0.77；R = 0.59 < 0.001）。此外，还开发了一个新的基于皮褶厚度的公式：FM% = 8.386 +（0.478×髂嵴皮褶）+（0.395×腹部皮褶，r = 0.78；R = 0.61；估计标准误差（SEE）= 2.62 %； < 0.001）。基于这些发现，国家和国际联合会现在将能够使用皮褶测量进行定期的身体成分评估。
