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.

Introduction and objectives: The long-distance running is a moderate intensity with long term duration exercise, which predominantly uses the aerobic system for energy production, with substrates recruited from carbohydrates and lipids. In this sense, proper nutrition is one of the bases for physical performance. The objective of this study was to examine the anthropometric status, dietary intake and nutrition knowledge of street runners in Porto Alegre. Materials and methods: 16 male runners were evaluated and The Body Mass Index (BMI) waist-hip ratio, body fat, food intake, energy expenditure and nutrition knowledge were measured. Results and conclusion: Results showed that BMI waist-hip ratio and body fat percent were appropriate, however even demonstrating good nutritional knowledge, dietary intake of carbohydrates and calcium, did not reach the recommended intakes for that type of population. Our results reinforce the importance of individual nutritional orientation for all runners, in order to guide food choices, timing, quantities, frequency, to provide an effective nutrition education for health and performance.

This study aimed to systematically review and analysis of the effects of dietary supplements, in particular L-Carnitine and Conjugated Linoleic Acid (CLA) on the reduction of body fat. We systematically reviewed articles published from 2000 until August 2010. The databases were consulted: PubMed, HighWire, Medline, ScielO and EBSCOhost. For detection of articles, we used the descriptors listed below: Conjugated linoleic acid, L-Carnitine, Supplementation, Weight loss and Obesity. Among the most important findings related to the use of CLA, there is the weight reduction, side effects such as increased insulin resistance, elevated blood glucose and fasting insulin levels, elevated lipid peroxidation and reduced HDL-cholesterol in subjects with metabolic syndrome. For supplementation with L-carnitine, smaller studies had scientific plausibility, since no one could prove the effectiveness of this supplement to reduce body fat. Thus, the recommendation of such supplements with specific purpose of weight loss should be avoided for specific cases and the recommendation should be made cautiously.

Introduction: The incorporating of healthy eating habits is a major concern worldwide. It is known that, to be healthy, one must consider not only the feeding of an individual, but also other habits such as regular practice of physical activities. However, some eating precautions must be taken into consideration so that health is not impaired. The inclusion of certain cereals as a food supplement is a viable strategy to avoid any lack of nutrients such as essential amino acids. The quinoa, for example, is a cereal composed of proteins that may benefit health and sports. Objective: The objective of this study is analyze the amino acid profile of quinoa and check the possibility of being consumed by individuals engaged in physical activities. Literature review: In assessing the nutritional composition of quinoa, we could verify that it is a food that includes all the essential amino acids, with no limiting amino acids such as lysine and tryptophan, unlike other cereals. In addition, it is highly digestible in comparison to other vegetable and animal food. Conclusion: Quinoa is a food that can promote health and athletic performance of individuals due to its content of amino acids and its high bioavailability. It is recommended the realization of practical studies with the cereal to sportsmen for better evaluation of its nutritional benefits. Key words: Quinoa; Nutrition; Essential Amino acids; Sports.

Excess body fat is a problem that increases every year and the combination of nutrition and resistance training (RT) has been shown to be a promising intervention in improving body composition. However, the impact of different dietary macronutrient distributions during the TR is not well understood. Thus, this study examined the influence of dietary macronutrients manipulation in improving body composition in RT`s beginners. Method: Ten healthy and physically active male, between 18 and 24 years and who were not consuming any kind of dietary supplements, engaged in a three days/week RT for six weeks. Participants were divided into two groups: normal protein diet (0.8-1.0 g / kg) and high protein diet (1.6 to 1.8 g / kg). Three days dietary record was applied at the beginning (p0), after 3 weeks (p3) and the end of the study (p6) for checking diet adherence. Anthropometric measurements and 1-RM test were performed at baseline (p0) and at the end of the study (p6). Results: There was negative correlation between increased energy intake and loss of body fat (r = 0.926). However, there was no relation of the different distributions of macronutrients on body composition. Conclusion: Other factors independent of the diet appear to influence muscle hypertrophy and body composition in individuals engaged in TR and higher caloric intake does not lead to a greater lean mass gains.

The objective of this study was to investigate fourteen professional athletes jiu-jitsu in different categories, competing at state, national and international, of different ages and goals for the estimation of percent body fat (% BF), using the equation Oppliger and Tipton (1984). This study was characterized as a cross-sectional observational study. The average fat percentage of the sample was 11.4±3.6. Analyzing the results for the parameters proposed by Heyward & Stolarczyk (1996) it was observed in a fighter's super-heavyweight category the highest value calculated for the percentage of fat (14.9%), ranked as average. For the lowest calculated value, a lightweight fighter, the percent fat of 5.3%, classified as hazardous. Analyzing the results of the fat percentage of Jiu-jitsu, there was a linear increase according to weight categories of heavier athletes tend to have a higher percentage of fat, this is confirmed by male wrestlers that point to a low fat percentage (less than 10%) except for the heavier categories as heavyweight to (84.99 kg), heavy (up to 90.99 kg), super-heavyweight (up to 96.99 kg) and very heavy (over 97 kg). Based on these results, studies are needed with larger samples and more precise methods to enable a statistical evaluation and a conclusion more refined.
