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. Key words: Esthetics, Athletic Performance, Nutritional Supplement.

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. Key words: Performance, Nutrition, Dehydration, Fighters.

The present study aimed to evaluate the nutritional status and physical activity (walking and running) in adults in the city of Coari, Amazonas. We evaluated 140 subjects of both sexes, between 18 and 60 years of age captured by convenience. Anthropometry was used for body weight, height, Body Mass Index, body fat percentage. We evaluated the physical activity, hydration and feeding frequency through interviews using a questionnaire. The walk was practiced by about 94% of the sample and running by 6%. The women practiced walking or running in five more days a week mostly, while the men up to 4 days (52,2% vs 52%; p-valor=0,025). Only 12.1% performed fluid replacement before, during and after walking or running. Most performed three meals per day (39,3%). The majority of respondents were overweight according to Body Mass Index (62,8%), or overweight (45%) and obesity (17,8%), higher frequency of obesity in males according to the percentage of body fat (44,0% vs 24,4% p-value = 0,015). More intervention strategies and improved practices of physical activity and eating habits are necessary in this population. Key words: Exercise. Obesity. Nutritional status.

This study aimed to assess the energy intake and macronutrient of athletes from Guarapuava’s futsal in the championship period, comparing the informations obtained with recommendations for age, sex and physical modality, as well as the contribution of maltodextrina intake in daily energy. We evaluated all the athletes of the team, being 13 the number of members. For feed assessment, we used dietary information from the registry type Food Day Four, adopting the analysis to descriptive statistics and Student t-test to detect differences between average values of the variables: total energy value total energy value per kilogram and grams of carbohydrate with and without the values of maltodextrin. The results demonstrated that the energy intake and of lipids showed percentages below than the recommended daily, while carbohydrates and proteins showed percentages with the appropriate recommendations, although an adequate intake of carbohydrates only occurred by ingestion of large quantities of maltodextrin. So, we could observe that the group of athletes evaluated consuming nutritionally deficient diets for physical activity. Key words: food habits, sports, energy intake

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.
