Investigação de elementos químicos em sangue total de judocas utilizando a técnica de fluorescência de raios X

Abstract in Portuguese
O objetivo do presente estudo foi direcionado a avaliação de elementos químicos, de relevância nutricional e clínica, em sangue total de judocas submetidos a plano alimentar balanceado com suplementos (G1) e sem suplementação (G2) visando maior entendimento das necessidades nutricionais e adequação das necessidades diárias em função do desempenho esportivo, uma vez que pequenas variações desses elementos podem levar a perda de rendimento e deixar o organismo vulnerável aos problemas de ordem patológica. As coletas de sangue total foram realizadas após 6 meses da implantação do protocolo nutricional para posterior comparação entre os grupos (G1 e G2). Para essa análise foram empregadas as técnicas de Fluorescência de Raios X por Dispersão de Energia (FRXDE) e Análise por Ativação com Nêutrons (AAN). Estas técnicas analíticas são complementares e possibilitaram a análise quantitativa dos elementos Br, Ca, Cl, Fe, K, Na, P, Rb, S e Zn compondo dados de uso na medicina esportiva que podem beneficiar o atleta durante o treino e recuperação. Verificou-se que as dosagens de Cl, K, P e S em sangue total para todos os judocas encontram-se dentro dos intervalos de normalidade, independente do controle alimentar. Entretanto, as dosagens dos demais elementos mostraram variações, tanto para G1 como para G2 em relação ao grupo de controle, quando as comparações foram realizadas em função do gênero. Os resultados mostram a necessidade de adotar dieta personalizada, otimizando o desempenho e recuperação dos judocas, além de contribuir para a proposição de novos protocolos de avaliação nutricional e clínica ainda não descritos na literatura.

Abstract in English
The objective of the present study was the evaluation of chemical elements of nutritional and clinical relevance in the whole blood of judokas submitted to balanced food plan with supplementation (G1) and without supplementation (G2), aiming at a better understanding of the nutritional needs and adequacy of the diets. The daily needs depending on sports performance, since small variations in the nutrition's can lead to loss of performance and leave the body vulnerable to pathological problems. Whole blood analyses were performed 6 months after the implementation of the nutritional protocol using EDXRF and INAA techniques.These analytical techniques are complementary and enabled the quantitative analysis of the elements Br, Ca, Cl, Fe, K, Na, P, Rb, S and Zn, composing data for use in sports medicine that can benefit the athlete during training and recovery. It was found that the dosages of Cl, K, P and S in whole blood for all judokas are within normal ranges, regardless of dietary control. However, the dosages of the other elements showed variations, both for G1 and for G2 related to the control group, when the comparisons were carried out according to gender. The results show the need to adopt a personalized diet, optimizing the performance and recovery of judokas, in addition, they contribute to the proposition of new nutritional and clinical assessment protocols not yet described in the literature.
