Introduction: professional soccer both in the local setting and in other countries is highly competitive, and those who practice must have specific morphological, anthropometric, and body composition characteristics, in addition to constant monitoring of nutritional and training interventions. Currently, the gold-standard criterion for the evaluation of body composition is Dual Energy X-ray Absorciometry (DXA), which is a costly laboratory method with limited use for many professionals. Knowing which field methods obtain similar results to this would allow a better interdisciplinary approach, which could have a positive impact on sports performance. The objective of this study was to evaluate the accuracy of different formulas for predicting fat percentage and fat mass, as compared to DXA, in Colombian soccer team players. Methods: a cross-sectional, analytical study using convenience sampling. A total of 79 professional male soccer players, belonging to 4 Colombian first and second division clubs, were included. Thirty anthropometric variables were measured, wherewith a descriptive analysis was performed using the SPSS v.21 program, and a procedure with analytical scope was carried out to establish concordance indices between different measurements using the Bland and Altman method. This statistical process was performed using the library (BlandAltmanLeh) of the statistical program "R". Results: average age was 23 ± 4.4 years, and the percentage of body fat was estimated using six equations: Jackson and Pollock (7.20 ± 2.58 %), Yuhasz as modified by Carter (7.52 ± 8.50 %), Reilly (10.04 ± 1.43 %), Faulkner (11.23 ± 11.90 %), Pariskova and Buskova (11.08 ± 16.06 %), and Durnin and Womersley (12.41 ± 20,10 %), in addition to the calculation of fat percentage for fat mass using the five-component method (13.17 ± 2.86 %). The percentage of body fat that showed the lowest intermethod difference was fractionation by five components (0.54 ± 3.56), followed by Durnin and Womersley (0.66 ± 3.52). Conclusion: the calculations of fat percentage using the fractionation of 5 components method and the Durnin and Womersley equation were closest to the results obtained by the gold-standard method (DXA) in soccer players of Colombian professional teams.
无论是在当地还是其他国家，职业足球竞争都极为激烈，从事这项运动的人除了要持续监测营养和训练干预措施外，还必须具备特定的形态、人体测量和身体成分特征。目前，评估身体成分的金标准是双能X线吸收法（DXA），这是一种成本高昂的实验室方法，许多专业人士使用受限。了解哪些现场方法能获得与该方法相似的结果，将有助于采取更好的跨学科方法，这可能对运动表现产生积极影响。本研究的目的是评估在哥伦比亚足球队球员中，与DXA相比，不同公式预测脂肪百分比和脂肪量的准确性。方法：采用便利抽样进行横断面分析研究。纳入了来自哥伦比亚4个甲级和乙级俱乐部的79名职业男性足球运动员。测量了30个人体测量变量，使用SPSS v.21程序进行描述性分析，并使用Bland和Altman方法进行分析范围的程序，以建立不同测量之间的一致性指数。此统计过程使用统计程序“R”的库（BlandAltmanLeh）进行。结果：平均年龄为23±4.4岁，使用六个公式估计体脂百分比：Jackson和Pollock公式（7.20±2.58%）、经Carter修改的Yuhasz公式（7.52±8.50%）、Reilly公式（10.04±1.43%）、Faulkner公式（11.23±11.90%）、Pariskova和Buskova公式（11.08±16.06%）以及Durnin和Womersley公式（12.41±20.10%），此外还使用五成分法计算脂肪量的脂肪百分比（13.17±2.86%）。方法间差异最小的体脂百分比是五成分法（0.54±3.56），其次是Durnin和Womersley公式（0.66±3.52）。结论：在哥伦比亚职业球队的足球运动员中，使用五成分法和Durnin与Womersley公式计算的脂肪百分比最接近金标准方法（DXA）获得的结果。
