Performance assessment and ponderal loss by the carbohydrate intervention in practitioners of Brazilian jiu jitsu/Avaliacao do desempenho e perda ponderal atraves da intervencao de carboidratos em praticantes de jiu jitsu

Introduction: In jiu jitsu exist weight loss due to high dehydration during the training. When there is a low in carbohydrate reserves, the ability of the athlete to keep training decreases. Objective: To evaluate the results in an intervention with carbohydrate. Materials and Methods: The study in Ceilandia, DF, in January 2012. We evaluated 12 practicing of jiu jitsu divided into 4 groups. Each group received a type of carbohydrate, water, maltodextrin, brown sugar and banana, respectively. To calculate the average percentage of weight loss of each group was used a formula. To evaluate the performance, was made two tests: push-ups and long jump. Results: There was little variation in weight loss, and compared to other groups, the lowest weight loss was the intervention of water. (0.5%). The best performance in resistance training with push-ups was the intervention with maltodextrin. For muscular strength and power with long jump, the best result was for intervention with brown sugar. Discussion: The results may have been interfered with because of difference in feed of the individuals and the better fitness when compared to others of the same study. Conclusion: It is still important the hydration, however, still need more studies to show a better option to use carbohydrates for a better performance during the training of jiu jitsu.

Quando ha uma baixa na reserva de carboidrato, a capacidade do atleta se manter exercitando diminui. Objetivo: Avaliar os resultados em uma intervencao com carboidrato. Materiais e Metodos: Estudo realizado na Ceilandia, DF, no mes de Janeiro de 2012. Foram avaliados 12 praticantes de jiu jitsu divididos em 4 grupos. Cada grupo recebeu um tipo de carboidrato, agua, maltodextrina, acucar mascavo e banana, respectivamente. Para calcular a porcentagem media de perda ponderal de cada grupo foi utilizada uma formula. Para avaliar o desempenho, foi feito dois testes: flexoes de braco e salto em distancia. Resultados: Houve pouca variacao de perda ponderal, sendo que comparado aos outro grupos, a menor perda de peso foi a intervencao com agua.(0,5%). O melhor rendimento no treino de resistencia com flexoes de braco foi a intervencao com maltodextrina. Para forca muscular e potencia com salto em distancia, nao houve uma diferenca satisfatoria. Discussao: Os resultados podem ter sido in
