Introduction: Dietary supplements are added to diets products, containing at least one of ingredients: vitamins, minerals, amino acids, proteins, antioxidants, carbohydrates, lipids, fatty acids, or a combination of any of these. They are marketed under various purposes, such as improving some aspect of physical performance, mainly to increase muscle mass, reduce body fat, increase aerobic capacity, stimulate recovery and / or promote some feature that improves sports performance. Evaluate the characteristics of users of dietary supplements. We conducted a cross-sectional study with 102 customers and stores or pharmacies in São Paulo, the researcher and two trained promoters administered the questionnaire through interview technique. We included clients who reported using some type of nutritional supplementation after signing the consent form. Data were organized into spreadsheets Microsoft Office Excel 2007 and presented by means of figures and tables: Most users are male (57.04%), have higher education (54.06%), spend around R $ 50.00 to $ 100.00 monthly with supplements (51%), using 1-2 different types of supplements for different purposes (44%), do not bother to read the labeling information (66%), coach of 3 to 5 times a week (73.53%) of 1 or 2 hours per day (65.69%), starting between 1 and 6 months (54.90%). Users are mostly people with higher education, who practice physical activity at gyms, use more than one type of supplement and without the specialized professional. Key words: dietary supplements, athlete, exercise, supplementation.

Currently, the use of dietary supplements is the focus of major research about potential ergogenic effects on human physical performance. Athletes or physically active for health and quality of life seek to use dietary supplements as a way to increase their earnings and results. The big problem is that the bad information and guidance not correct supplementation can lead to difficulties in earnings as desired by physically active. The correct orientation is what makes all the difference, since dietary supplements are not only important gains in muscle mass and reducing body fat, but many of them can bring interesting benefits that can help improve the quality of people's lives. This study seeks to specify the supplementation of branched chain amino acids and its significance for physical activity either in or not athletes in different sports training protocols. This present study employed a systematic review of supplementation of branched chain amino acids and their effects on human physical performance, this also will report, the metabolism of these amino acids in relation to fatigue and the synthesis of other amino acids important during physical exertion. With this review it is concluded that the supplementation of branched-chain amino acids are also highly questioned regarding the central fatigue and muscle gains, further studies addressing the effects of long-term supplementation.

The present study aimed to evaluate the necessity of the use of electrolyte drinks by bodybuilders, by consuming food and nutritional needs as sex, age, type and duration of training conducted. A total of 18 bodybuilders that use energetic repositories were evaluated on a gym located at Lajeado city. A questionnaire was administered to evaluate the food consumption and another structured questionnaire concerning the lifestyle of the person, physical exercise and use of sports drinks. Nutritional evaluation was performed through the Body Mass Index (BMI). The Gatorade sport drink was the most consumed with 55.6% (n = 10) of the participants. The mean of the carbohydrate macronutrient consumed within three days observed were 56.52% (NS), 54.71% (NS) and 57.19% (NS) showed no significant difference when compared with the reference values of DRI (2002). Among the micronutrients analyzed, it was found that potassium did not reach its maximum recommended (4.7 g / day), significantly less than the reference value (DRI) (3.12 g / day (p = 0.000), 2.48 g / day (p = 0.000) and 2.66 g / day (p = 0.000)). Regarding sodium, it was found that the amount consumed per day was 3.18 g (p = 0.000), 2.29 g (p = 0.002) and 2.56 g (p = 0.001) and it was significantly higher than the reference value (1.5 g / day). Thus it is concluded that ingestion of electrolytic drink is not suitable for the population studied, since the quantity of sodium ingested with food and isotonic exceeded the recommended amount, and this characterizes a risk factor for developing hypertension and other chronic diseases in the future. Key words: Hydration, Drink hydroelectrolytic. food consumption.

Objective: To evaluate the relationship of lipid profile and anthropometric indicators with different values of the ratio TG / HDL-C in patients with type 2 diabetes with and without lipid-lowering medication. Materials and Methods: Descriptive observational study with an analytical component, conducted with 85 diabetics of both sexes, aged 20 years, outpatients at the Hospital of the Federal University of Pernambuco (HC / UFPE). Results: Of the sample, 46 patients were using lipid-lowering medication and 39 did not use. Mean age was 61.6 ± 9.2 years, 57.6% of the sample of elderly, 78.8% females and according to BMI, 67.0% were overweight. Among the groups, there was no statistically significant difference in the lipid profile, anthropometric indicators and reason TG / HDL-c. However, all anthropometric indicators show themselves capable of identifying high values of the ratio TG / HDL-c. Discussion: Although it is recommended that dyslipidemia is treated aggressively, this goal is not always achieved. Thus, these individuals must be subjected to more effective preventive treatments not only by the medication but also the change of lifestyle. The literature also shows that the ETS is the best parameter to detect high ratio TG/HDL-c. Conclusion: A better control of lipid levels in these patients, through change of lifestyle. It is also suggested the use of indicators RCE, WC and BMI as instruments to detect possible changes in the ratio TG / HDL-c. Key words: Diabetes mellitus, lipid-lowering drugs, cardiovascular risk, dyslipidemia.

The present study aimed to evaluate the nutritional status of gym instructors and check your eating habits. The sample consisted of 18 gym instructors of Frederico Westphalen-RS. To assess the nutritional status, we collected measures of weight, height, arm circumference (AC), waist circumference (WC), hip circumference (HC) and body fat percentage. With these measures we calculated the Body Mass Index (BMI) and waist-to-hip ratio (WHR). The feeding behavior and physical-activity level were analyzed using the standardized questionnaire proposed by the Ministério da Saúde (MS). We found that most professionals had proper values for BMI (61.1%) and for AC (72.2%), WC (61.1%) and WHR (72.2%) classifications. More than half (55.6%) of the samples presented body-fat percentage classified as high and very high. Feeding behavior assessment showed that 77.8% of the professionals under investigation reported proper eating habits. However, only 16.6% had a healthy diet of a nutritional point of view. About 94,4% of participants stated performing regular exercise. Despite the physical appeal and the current demands of the profession, the sample under investigation did not reach high levels of adequacy in relation to nutritional status and eating behavior. Further investigations could elucidate more clearly the nutritional characteristics of these professionals. Key words: Nutritional assessment, Dietary habits, Physical activity.

This study aimed to estimate the nutritional knowledge of users and non-users of dietary supplements that practice gym exercises in the city of Chapecó - SC. The study population was attended by 92 practitioners from the gym, the users of dietary supplements in individuals were (21.7%, n = 20) and nonusers were (78.2%, n = 72). There were answered two questionnaires, which allowed us to evaluate the profile of the population and their nutrition education. In the population, we could observe that the average age is 30.78 + - 10.570, and the predominant socioeconomic status is the class B, in the schooling, the complete secondary education or incomplete higher education prevailed. In the users public, the men stood out in relation to women because it has nutritional knowledge classified as moderate and high. In the non-users public, the female stood out for present a greater number of individuals with moderate and high nutritional knowledge. When we compared the level of nutritional knowledge among the group of users and non-users of dietary supplements the mean scores found were 8.00 + - 0.42 and 7.28 + - 0.22, respectively, so there was no statistical difference (p = 0.13) between the groups. However, both for users and non-users of dietary supplements, the research has shown that they have interest in nutrition, considering that the vast majority of respondents have moderate nutritional knowledge, while a small percentage has high nutritional knowledge.

Introduction: athletes of fights commonly use the strategy of weight loss before competition in order to compete in lower categories. Thus, they seek to benefit by reducing their weight before the official weigh and trying to recover it in a short period of time between weighing and fight. However, this practice can be dangerous without proper professional supervision. Objective: the objective of this study was to investigate the prevalence of judo athletes who use methods of weight loss in pre-competitive period, and what are the strategies used for weight loss and what is the perception of athletes in relation to this procedure. Materials and Methods: 33 judo competitors at the national level (24.5 ± 4.6 kg.m-2) answered a questionnaire with questions regarding the use or not of weight loss strategies, and what are the strategies for weight loss often used in pre-competition period. Results: 93% use methods of weight loss pre-contest. 48% reported that the method affected performance. The strategies more used were intense training, caloric restriction and dehydration, respectively. Conclusion: we conclude that the amount of judo athletes who use weight loss pre-competition is high, and the methods used seem to decrease performance in competition, as reported by the athletes investigated.

The study aims two different procedures for administration of creatine to laboratory rats. Wistar rats (90 days) were divided into three groups according to the mode of administration of creatine for four weeks: control group (C): rats that did not take creatine, creatine group gavage (G) rats that received creatine supplementation (0.107 g / kg body weight) by gavage and creatine group maltodextrin (M) rats supplemented with creatine (0.107 g / kg body weight) with the addition of maltodextrin (0.160 g / kg body weight) by gavage. At the end of the experiment the body mass gain, area under the curve of food and water intake, rate of hydration of the gastrocnemius muscle, serum creatine concentration and hepatic glycogen concentration in liver and muscle (gastrocnemius and soleus) were evaluated. Weight gain, the area under the curve of food intake and hydration rate of muscle did not differ between groups. The area under the curve showed increased water intake for the animals of group M in the animals of group G. The concentration of creatine serum and muscle showed no differences, as well as liver glycogen levels and the gastrocnemius muscle, while for the soleus muscle there was an increase due to the creatine groups G and M. When the concentration of creatine in the liver was examined and observed an increase in this substrate. Thus, it could be concluded that the way is creatine administration may interfere with his metabolism. Key words: Supplementation, Maltodextrin, Physical exercise, Gavage.

The study aimed to observe the dehydration in male athletes in football, during the youth, using the monitoring of the mass / body weight and contribute information to improve performance. The research character is pre-experimental, whose proposed intervention type is before - after. The study sample was composed of twenty players in the under-18 Mato Grosso Sport Clube (Union Sports Club) in the city of Rondonopolis / MT, of these, fifteen were selected because they meet certain criteria. The study population has an average age of 16.4 years, height 1.69 cm, with percentage fat and BMI 12.08 and 26.6. The value of body weight was collected before and after two training sessions on different days with balance and fluid intake was collected using a measuring cup from the moment of arrival at the training center for training and training order. These data were collected on days of normal training. For data analysis we used the "t" Student test for paired samples and p <0.05 as significance level. As a result, the mean body weight found, reported a decrease in body weight (65.25 and 64.46 pre-to post-training) when hydration occurred spontaneously. When performed an orientation and regular breaks, these data had a small changes, for example, body weight remained more balanced (pre 65.3 to 64.7 in the post-workout). Although not a significant difference occurs, it is concluded that the pre and post values have not changed, especially the second time after a guidance and recommendation for fluid intake during exercise. Key Words: Dehydration, football, training, performance, body weight.

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.

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.
