Estudio comparativo de la composición corporal tras intervención dietética nutricional en futbolistas ecuatorianos de elite durante pretemporada.

Abstract

Introduction: Personalized diet and body composition (BC) evaluation in athletes are essential, allowing the establishment of objectives and strategies that converge in training and diet in order to achieve sporting success. The objective of this study was to compare BC after a dietary intervention in Ecuadorian professional soccer players. Material and method: Anthropometric variables were analyzed according to the protocol of the International Society for the Advancement of Kineanthropometry (ISAK) at the beginning and end of the preseason after a dietary intervention, evaluating their BC and calculating the fat mass (FM) and fat free mass (FFM) with the Yuhasz equation modified by Carter in 1982. Descriptive statistical methods (mean ± standard deviation (SD)) and t-student analysis were used. Results: After the dietary intervention at the end of the preseason where 21 Ecuadorian professional soccer players were evaluated, mean values of age (24 ± 4.51), height (1.79 ± 0.07) and weight (76.57 ± 6.64). The BMI obtained was 24.91 ± 1.65, with the mean value of body fat percentage (% BF) being 7.99 ± 1.16. The FM (kg) resulted in 6.10 ± 1.15 and the FFM (kg) in 70.48 ± 5.93, obtaining statistically significant changes in these last three variables. Differences were found in %BF from a dietary intervention in reference to other players of different nationalities where only their BF was evaluated without applying a food treatment. Conclusions: The BC profile improves after a 7-day dietary intervention in the preseason phase, in this way the sports performance of professional soccer players could be optimized.
