          Abstract

          Resumen Introducción: el fútbol profesional, tanto a nivel nacional como internacional, es de alta competencia. Los futbolistas deben tener características antropométricas y de composición corporal específicas. El criterio de referencia para la evaluación de la composición corporal es la absorciometría de energía dual de rayos X (DXA), cuyo uso es limitado al ser un método de laboratorio y tener un elevado coste. Conocer qué métodos de campo obtienen resultados similares podría permitir mejores intervenciones nutricionales y de entrenamiento, repercutiendo positivamente en el rendimiento. El objetivo de este estudio fue evaluar la precisión de distintas fórmulas de predicción del porcentaje de grasa y masa adiposa, en comparación con la DXA, en futbolistas de equipos colombianos. Métodos: estudio analítico transversal con muestreo a conveniencia. Se evaluaron 79 futbolistas profesionales de 4 clubes colombianos. Se midieron 30 variables antropométricas y se realizó un análisis descriptivo en el SPSS v.21, así como un análisis de las correlaciones e índices de concordancia utilizando la prueba de Pearson o de Sperman y el método de Bland y Altman, respectivamente, ambos con el programa estadístico R. Resultados: se estimó el porcentaje de grasa corporal utilizando seis ecuaciones: Jackson y Pollock (7,20 ± 2,58 %), Yuhasz (7,52 ± 8,50 %), Reilly (10,04 ± 1,43 %), Faulkner (11,23 ± 11,90 %), Pariskova y Buskova (11,08 ± 16,06 %) y Durnin y Womersley (12,41 ± 20,10 %). Se calculó el porcentaje de grasa de la masa adiposa con el método de los cinco componentes (13,17 ± 2,86 %). El porcentaje de grasa corporal que presentó menor diferencia intermétodos (DIM) fue el de fraccionamiento por cinco componentes (0,54 ± 3,56), seguido del obtenido por la fórmula de Durnin y Womersley (0,66 ± 3,52). Conclusión: el cálculo del porcentaje de grasa a partir del fraccionamiento de 5 componentes y la ecuación de Durnin y Womersley fueron los más cercanos a los resultados obtenidos por el método de referencia, la DXA, en los futbolistas de equipos profesionales colombianos.

          Abstract 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.

          American College of Sports Medicine Joint Position Statement. Nutrition and Athletic Performance.

          It is the position of the Academy of Nutrition and Dietetics, Dietitians of Canada, and the American College of Sports Medicine that the performance of, and recovery from, sporting activities are enhanced by well-chosen nutrition strategies. These organizations provide guidelines for the appropriate type, amount, and timing of intake of food, fluids, and supplements to promote optimal health and performance across different scenarios of training and competitive sport. This position paper was prepared for members of the Academy of Nutrition and Dietetics, Dietitians of Canada (DC), and American College of Sports Medicine (ACSM), other professional associations, government agencies, industry, and the public. It outlines the Academy's, DC's and ACSM's stance on nutrition factors that have been determined to influence athletic performance and emerging trends in the field of sports nutrition. Athletes should be referred to a registered dietitian/nutritionist for a personalized nutrition plan. In the United States and in Canada, the Certified Specialist in Sports Dietetics (CSSD) is a registered dietitian/nutritionist and a credentialed sports nutrition expert.
