Introduction: Were studied women attending a SPA in São Paulo in order to evaluate the percentage of water, lean mass and fat mass before and after seven days, with diet and exercises. It was noticed weight loss and also an improvement in body composition. Objective: To evaluate the loss and/or gain muscle mass, body fat and water and compare the initial and final physical assessment of women attending a SPA, which underwent a 1200Kcal diet associated with physical activity. Materials and Method: The study was conducted with 15 women between 24 and 68 years old. The evaluation was done by measuring weight and height, and bioelectrical bioimpedance analysis. Result and Discussion: We Calculated the mean and standard deviation of results achieved ate the beginning and in the end of the study, and it was noticed a significant difference between the parameters. Conclusion: During seven days of monitoring, with 1200Kcal diet, mild exercise, the weight loss ocurred, reducing the percentage of body fat and increase muscle mass and percentage of body water. Key words: Obesity; Diet; Physical Exercise.

Introduction: Rugby is a rising sport in Brazil, however there are few academic studies about athletes of this sport, particularly the risk of dehydration and hyperthermia. During a game there are few interruptions that provide an opportunity for intervention to fluid replacement, which may lead athletes to a state of dehydration and thermoregulatory inefficient. Purpose: To evaluate, during training, the degree of dehydration of a high-level competitive Brazilian rugby team to design strategies to combat the harmful effects of dehydration and hyperthermia. Methodology: 23 male athletes participate the test. It was performed tetrapolar bioimpedance tests, obtaining the following variables before and after 90 minutes of training without water intake: body mass (BM: kg), height (m) and percentage of total body fat (%BF). It was calculated the sweat rate (SR) and percentage of water loss (%WL) as positioning of the ACSM (2007). It was performed paired t-test (p <0.05). Results: The athletes were 26.2 ± 5.5 years old, 1.82 ± 0.06 m and %BF of 14.9 ± 4.2%. There was statistical difference between BM before and after training. The SR was 13 ± 5.5 mL/min and %WL of 1.3% ± 0.6%. Meir et al (2003) estimated SR in a game between 11 and 17mL/min although the reduction of %WL was <2%, this value has been identified as critical to the performance for thermoregulatory stress. Conclusion: Even though there is a low risk of dehydration, studies with professional rugby leagues indicate intermittent characteristic it self of the sport, damages may occur in physical and cognitive performance of high level athletes. Key words: Rugby; Hydration; Sweat rate; Dehydration.

Introduction: Both forwards and backs have anthropometric structure crucial for the success in sports. The high incidence of collisions requires physical characteristics of the players own speed, agility, endurance, strength, flexibility and other skills. The forwards need physical power, strength, a higher percentage of fat and muscle hypertrophy. The backs of speed, agility, good aerobic fitness and lower fat percentage. Objective: To analyze and compare with international standards body composition of Brazilian athletes of high level rugby. Methods: Participants were 22 elite athletes rugby boys. The variables collected were age, weight (Tanita digital scale Iroman ® model BC558), height (stadiometer Laser Strait-Line ®), and nine skinfolds (Lange) to calculate the percentage of fat (% BF) by Jackson and Pollock (1978). The study was approved by the Ethics Committee of the University Center (COEP 47/05) and the participants signed a consent form. Results: The sample had an average of 25 ± 4.7 years, 1.80 ± 0.10 m, 91.5 ± 12.7 kg and% G, 15.4 ± 5.7%. The monitoring of anthropometric rugby athletes featured area is parallel to the study of the evolution of the performance of professional players. It is well documented that in the amateur league players' G% gets to be 34% higher than the professional. The G% of Brazilian athletes, investigated in this study is among the forwards (15.2%) and backs (12.6%) professional league (Gabbett, 2002). Conclusion: Rugby is one of the most popular sports in the world and in Brazil is growing exponentially but few studies have traced the anthropometric profiles of players. Therefore, research studies can help trace cineantropomética somatotype future development of professional players from rugby league in Brazil, currently classified to compete in the 2016 Olympics.

The objective of this study was to evaluate the level of nutritional knowledge of bodybuilders from the gym of St. Paul and to determine the correlation with the level of education. The sample consisted of 24 bodybuilders (12 male and 12 female). Inclusion criteria was considered only bodybuilders over 18 years and that this activity regularly practiced for more than one uninterrupted year. It was observed that the average score obtained from the QCN indicated moderate level of nutritional knowledge (9,4 ± 1,1) and there is no difference between men and women with respect to score. Although a positive correlation between education level and QCN showed weak (r = 0,17). Thus was concluded that bodybuilders have a moderate nutritional knowledge. Even though our study does not appear in a highly positive correlation between education level and nutrition knowledge, other studies suggest the need to invest in nutrition education strategy so that we can influence the knowledge about food and nutrition information. Finally, the need to conduct more research so we can have a wide range of articles on assessments of nutritional knowledge in physical activity and sport. Key words: Nutrition; Nutritional knowledge; validity; Strength.

Introduction: The search for the best fitness has led many people to the practice of various forms of physical exercise at gyms, indoor cycling among them, along with the consumption of supplements. Objective: To evaluate the consumption of supplements by practitioners of spinning and who indicated their consumption, as well as knowledge of nutrition in five academies of Belo Horizonte. Materials and Methods: A descriptive study was performed with 75 practitioners from spinning. We used a self-administered questionnaire. The selection of the academies and students was random. Results and Discussion: 9.3% of the sample used supplement. Of these, all used the protein and the indication for use arose primarily from a dietitian, with the exception of the east. The low consumption of supplements can be explained by the low duration of exercise. With regard to knowledge of nutrition was observed that the academy was the center that showed errors in the citation of the sources of carbohydrates and fats. In relation to sources of protein, the North was the region with more errors, and these regions with lower nutritional counseling. Conclusion: It is important the presence of a dietitian working in these regions to promote the nutritional knowledge needed, and allows the use of supplements, when necessary, be done with adequate technical support.
