This research focuses on a theme of the contemporary world, excessive concerns about body image in practitioners of exercise. The objective of this research is to analyze the relationship of body image, body image distortion, in practitioners of exercise. Furthermore, this study has some issues associated with the pursuit of a perfect body, such as food, sports supplementation and the overuse of steroids. 38 studies were selected for the writing of this study, including books and articles, which cover topics such as: body image, body image distortion, sports supplementation and overuse of steroids. The dissatisfaction of real body compared to the ideal standard disseminated by the media, the fear of being excluded or being devalued, associated with a speech that relates health to the appearance and immediacy in getting the wanted body collaborate that subjects use excess exercise, often endangering their health. It can be noticed that an increasing consumption of supplements without proper control and a clear need for new studies on supplements and their effects to improve the level of information and to ensure safe use. Thus, it is clear that people who practice physical exercises should seek guidance from a doctor or nutritionist in order to make the exercise healthily does not expose health risks.

Introduction: Caffeine is an ergogenic aid used in order to improve athletic performance due to possible intracellular effects on central and peripheral system, slowing the perception of fatigue and optimizing the cardiovascular, endocrine, muscular and nervous systems during exercise. Objective: This study aimed to investigate whether caffeine exerts influence on the yield of triathletes in the race of 5000 meters. Materials and methods: Nine male triathletes aged between 18 and 35 years were tested twice running 5000 meters, interspersed with a mean period of 7 days. In one test they consumed a capsule containing caffeine anhydrous (5mg/kg) and in the other containing maltdextrin as a placebo in a double blind design study. The test time was measured and blood samples were collected for measurement of glucose and lactate before and immediately after each test. Results: No significant differences (p>0.05) were observed in lactate and glucose values between tests with ingestion of caffeine and placebo. However, the average time for the test was significantly lower (p=0,002) after caffeine consumption. Discussion: Although, this is a relatively short distance, there was improvement in performance time after caffeine consumption. However, this improvement was not due to effects on the production of energy. More studies are needed to determine the physiological factors that underlie such an effect on performance. Conclusion: Caffeine worked as ergogenic resource and resulted in improved aerobic performance time of triathletes in the 5000 meters run.

In the last two decades, there is a global trend, the so-called nutrition transition, which is characterized by a decrease in the number of people with malnutrition and an increase in obesity levels. In Brazil, data from the Pesquisa de Orçamento Familiar (POF), conducted between the years 2008 and 2009 show that 49.0% of the total population of adults are overweight and 14.8% are considered obese. Thus, the aim of this study is to characterize the profile of patients seeking nutritional home. The study was characterized as exploratory, cross country, descriptive quantitative approach, in which we analyzed 38 case histories of patients who received nutritional care home (personal diet). The majority (84%) of the patients were females and the average age was 33.53 years. With respect to nutritional status (47%) are in the overweight range or at some level of classification of obesity and (74%) have tried some kind of diet for weight reduction previously. When asked about the emotional state (74%) were considered anxious. Through this study, we see the need to develop strategies in partnership with the patient, so that it is able to understand the importance of adding new habits, in order to find the solution to this problem.

Caffeine stimulates fatty acid mobilization by increased catecholamine release. The fatty acid oxidation spares muscle carbohydrate stores resulting delaying fatigue. Objective: The aim of this study was to investigate whether the influence of caffeine on lipolysis induces a reduction in blood glucose levels during an indoor cycling class. Materials and methods: Primary, clinical, prospective, analytical, controlled, comparative, observational study, performed at a single center. Participated in the study 19 men with mean age of 35 ± 8.1 years, physically active for at least 6 months 3 times a week. The subjects were randomly assigned to placebo (n = 7) and caffeine group (n = 12). The caffeine group received 5 mg/kg of caffeine 30 min before carrying out a ciclism indoor class. All participants ingested the same pre-test meal and fasted for 8 hours before the test. Two blood samples were collected, one at arrival, prior to the ingestion of caffeine and the second immediately after the exercise. Total cholesterol, triglycerides, HDL, LDL, VLDL, glucose, urea, creatinine, uric acid and lactate were measured. The study was double blind and statistical analysis was used from the Student's t test, considering significant p values <0.05. Results: There was statistical difference only in HDL (p<0.05) among both CG and PG and between individuals of each group. We conclude that caffeine consumption under the conditions of this study did not alter the lipid profile in order to induce a reduction in blood glucose levels and delay fatigue during an indoor cycling class.

Introduction: The practice of physical exercise causes physiological changes in the body and among them the increase in the rate of production of heat and sweating. The sweat production and subsequent evaporation thermoregulatory mechanism is more efficient, however, dehydration can compromise performance. There are several ways to evaluate the changes in hydration levels after the practice of physical exercise and among them, the measure of acute changes in body weight before and after exercise. Objective: To evaluate the changes in hydration levels of marathon runners after athletics. Materials and Methods: A total of 6 athletes athletics, the national average age of 29.67 years, fit the practice of competitive exercises. The study took place in two distinct stages one another in forty-five days. In each step, each of the athletes covered a distance of 20 km around an athletics track. In the first stage each athlete received every 4 kilometers of racing 200 milliliters of water to hydrate and the second stage was not allowed to hydrate athletes during the race. Body mass was measured before and immediately after exercise. Results: The results indicate that racing occurs without hydration leads to dehydration average of 2.14% of body weight. Discussion: It has been shown that fluid losses above 2% in relation to body mass can affect performance during sports. Conclusion: The practice of athletics with distance of 20 km leads to dehydration of 2.14% of body mass, which impairs the performance of the race.
