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 Ceilândia, 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.

A nutrition education directed to the exercise is of paramount importance for achieving the desired goal. The purpose of this study was to analyze the nutritional knowledge of the bodybuilders of the State Secretariat of Sports in the Federal District - Brasília/ DF. The study group consisted of 100 individuals of both sexes, body builders, who answered a questionnaire. The results showed that there were different goals with the practice of weight training, 38% (n = 38) individuals were intended to increase lean body mass and improve physical fitness, 43% (n = 43) lose weight and improve fitness, 6% (n = 6) only improve fitness and 13% (n =13) had other objectives, to prepare the muscles for another type of sport. As for nutrition, 90% believed that the type of food influenced in the result of training, 8% believed that there was no influence and 2% did not know. With respect to food, they showed some knowledge regarding the identification of food sources of macronutrients, but a little or none knowledge about micronutrients. However, 70% saw no need for the use of dietary supplements and 99% thought it important to receive nutritional counseling provided by a qualified professional, like a nutritionist. The results showed that the practitioners of strength training of the secretariat of state of the sports from federal district require a program of nutrition education and adoption of measures to improve knowledge about nutrition for the practice of physical activity.

The goal of achieving the body aesthetically perfect has led many women to consume dietary supplements that promise to enhance weight loss or gain of muscle mass in a short period of time. The objective of this study was to evaluate the consumption of dietary supplements by women who exercise in a Taguatinga / DF. The gym has approximately 300 students. The criteria for selection of participants were being female and practice physical exercises at least three times a week. We applied a questionnaire with seven multiple-choice questions with the following data: Age, education, income, number of supplements they consume, types of supplements consumed, referral source and purpose of the nutritional supplementation. It was noted that most participants were aged between 21 and 25 years, average education level, income from 3 to 4 times the minimum wage and they usually use two types of supplements. The most used were protein and thermogenic and objectives most frequently reported were hypertrophy, weight loss and fitness, and the main indications were made by store clerks and teachers who work in their own gym. We need greater awareness of the professionals who recommend the use of supplements without being able to do so as well as intensification of nutrition education on the part of the nutritionist, to avoid the indiscriminate use of such products.

The objective of this review is to show that supplementation with CLA may actually become one more nutritional resource associated with exercise to improve body composition in humans. It is emphasized that studies in humans with the most diverse populations and samples. The study consisted of individuals of both genders, with normal weight, overweight or obese, sedentary or trained, which contributes to the diversity of results. CLA was administrated mixture of two predominant isomers, trans-10, cis-12 and cis-9, trans-11. Daily doses ranged from 0,7 to 7,2 g/day and time of supplementation of 4 weeks to 24 months. Noted that doses above 3 g/day CLA has more positive response to change body composition. The mechanisms which CLA decreases body fat and increases lean body mass are not completely understood. Studies lasting more than 1 year showed that the CLA dose was safe and well tolerated. However, evidence in humans is currently mixed about if supplementation has a significant effect on body composition or not. Differences between the studies may be related to the isomeric mixture of the supplement, the effects in specific tissues and the low statistical power. Overall, it appears that CLA helps reduce BF and SAD in humans, but a minimal effect on BMI or BW. By the time, there is a better accepted on this supplementation in obese females. But more research with larger duration and better application of the method, with greater control on diet and exercise and more precise handling of the isomers are needed to determine the optimal amount of isomer of CLA that has a greater influence on body composition.
