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. Key words: Supplementation, BCAA, Physical Performance, Fatigue.

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.

Considering the high consumption of dietary supplements in gyms with ergogenic purpose associated with increased of various these products on the market, the aim of this study was to evaluate the use of supplements by body builders in gyms in Resende City, RJ. The group consisted of 95 subjects who answered a self-administered questionnaire. Being 62 students (65.4%) men and 33 (34.7%) females. It was verified that 76.8% of the population uses some form of nutritional supplement, and the protein concentrates have been the most common (64%) in order to increase muscle mass (75%). Most athletes consume supplements without professional guidance of specialist (75.4%) and only 20.5% were prescribed by the nutritionist. The percentage of consumption of supplements for men was 83.9% and 63.6% of women. So, it was observed that the consumption of dietary supplements in the studied group is high, and we need more studies and explanations of consumption and the consequences of the indiscriminate use of these substances. Key words: Sports Nutrition, Dietary Supplements, Physical Activity, Body Image.

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.
