Introduction: Combat sports are played by weight category. The higher the proportion of lean mass per kilogram of body mass, the greater the ability to express the strength of a fighter. Therefore, the estimate of fat percentage (%BF) is very important for determining the category in which the fighter will compete. Objective: Compare different methods of body assessment in athletes of the Brazilian Judo Selection. Materials and Methods: Six male athletes, from Brazilian Judo Selection, belonging to heavyweight division, aged between 23 and 29 years old were assessed. The %BF by Bioelectrical Impedance Analysis (BIA) has been provided directly by the device and also through the formulas proposed by Oppliger, Nielsen and Vance (1991) and Lukaski and Bolonchuck (1986). For skinfolds (SF) the equation Σ3 SF (Guedes, 1994) was used. The values of %BF and residual volume to hydrostatic weighing (HW) were predicted respectively by Siri (1961) and Goldman and Becklake (1959) equations. Results: the average of %BF, according to BIA was 26,7 ± 6,3, formula of Oppliger, Nielsen and Vance (1991) was 13.1 ± 2.3, and formula of Lukaski and Bolonchuck (1986) has indicated 26.5 ± 8.6 and the average obtained by Σ3 SF Guedes (1994), showed results of 26.3 ± 2.9, which was the average closest to that of HW 21.6 ± 5.0. Discussion: the formula proposed by Oppliger, Nielsen and Vance (1991) was the only one that statistically showed a significant difference when compared to the gold method, HW. On the other hand, the SF method was the one that showed the highest correlation with HW. Conclusion: The SF method using the protocol of Guedes (1994) was the one that showed the highest correlation with HW, suggesting the use of it to calculate %BF of athletes of judo’s heavyweight division.

Introduction: The introduction of supplements in the media is becoming more intense and faster than the development of regulations and conducting scientific research to prove its real effects, that can determine the safety of its long-term use. The use of supplements by the general public is not quantified, and little information on this subject is published in the literature. Objective: To identify the prevalence on the use of supplements in one of the stores supplements Curitiba / PR and the factors associated with its use. Results: For many, were assessed 24-goers store supplements, all consumed some type of supplement, of which 71% were male and 29% female.

There was also a portion of people (13%) being driven by physical education teachers. Discussion: The results point to the ease of use of supplements, and often consumed with no indication of a trained professional. Conclusion: The use of supplements is significant in the group analyzed, showing the need for further research into the use of these products and their beneficial and harmful effects, focusing on aspects of nutrition education for the consumer of supplements to increase the level of information ensuring greater security in their use. Key words: Nutritional Supplements; Physical Activity; Nutrition Education; Sports Nutrition.

Objective: To assess the use of nutritional supplements, or other resources ergogenic by individuals practicing bodybuilding in gyms of a neighborhood in Florianopolis, and through the analysis of the data identifying the type of product used, purpose of use, the sources of indication for the use and nutritional guidance. Materials and Methods: We selected 98 practitioners of bodybuilding of 3 gyms in a district of the city of Florianópolis SC. Data were collected through a questionnaire regarding the use of supplements. Results: Among the 98 questioned, 50% used supplements. For consumers, 77,6 % were male and 22,4 % female, 55,2 % had higher education, 79,6 % had as objective to increase muscle mass. The supplement most cited was Whey protein® (32,5%). The main source of indication was on its own initiative (34,7%), in relation to dietary guidance, it also prevails own initiative (57,1%). Conclusion: Concerning the fact that the majority of the practitioners use nutritional supplements without indication of a specialist in nutrition, in addition to the huge lack of information, and many questions about the use of supplements as well as on a proper diet, it is clear the emerging need for the presence of nutritionists for awareness of this practitioners, in gyms and places to practice sports. After all, the lack of knowledge about nutrition can influence the typical pattern of an athletic group and, consequently, its performance and health.

Objective: To study hydration practices of men Jiu-jitsu, both in training, and during the competitions of this sport. Materials and Methods: In this study employment is an exploratory methodology, through a descriptive study, by employing a standardized questionnaire containing 18 objective questions and self-governing, as applied to athletes before a marathon, and judo. We delivered a total of 100 questionnaires, of which 91 returned questionnaires. Thus, for the calculations involving the study, we build on the 91 questionnaires returned. The study inclusion criterion was the sex of Jiu-jitsu and is not therefore required the involvement of members belonging to the female, thus aiming to restrict the universe of our study group. Results and Discussion: Given that only those who hydrate during training or competition had a custom fit for your best performance, we found that more than 70% of the practitioners interviewed consume fluids during training and competitions. It is interesting to note that the number of athletes with poor habits of hydration at 45% of respondents, especially during competitions, demonstrating the lack of knowledge about the importance of proper hydration with the aim of a good physical performance.
