Performance assessment and ponderal loss by the carbohydrate intervention in practitioners of Brazilian Jiu Jitsu

Abstract

Introduction: In jiu jitsu exist weight loss due to high dehydrationduring 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 Ceilândia, DF, in January 2012. We evaluated 12 practicingofjiu 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 infeed of theindividualsand thebetter fitness when compared to others ofthe same study. Conclusion: It is still important the hydration, however, still need more studies to showa better option to use carbohydrates forabetter performance duringthetrainingof jiu jitsu.
