The objective of this Study was to estimate the energy expenditure during a race pedestrian orienteering in male athletes of category H21E. The study population was consisted of runners affiliated to the Gaúcha Orienteering Federation (FGO) and the Brazilian Orienteering Confederation (CBO). The sample consisted of 06 athletes from the elite category. They followed a track with 30 control points, with a distance between the points a total of 8100 meters. Therefore, to determine the distance and time, were used the Helga Orienteering Software Program, version 2010/07-1, specific software for analysis of route guidance. Through the OCAD Program was made a topographical analysis of the letter and thus determining the slope the terrain. The O2 consumption is a function that depends on the intensity of the work performed and body mass displaced, so it was necessary to check the corporal weight of each athlete. To represent the amount of energy expended was used the formula where 1 = V02 1 .min 5 Kcal. To estimate O2 consumption equations were used to ACSM, during the race at speeds above 134 m / min, we used the formula, VO2 = (0.2 x speed) + (0,9 x speed x 9 x Tilt) + 3.5 and for walking at speeds between 50 and 100 m / min the equation, VO2 = (speed x 0.1) (1.8 x speed x Tilt) + 3.5 and for speed between 100m/min and 134m/min, considered trot, it was for this work the same formula of the race, this equation is capable of use for these speeds if the individual is actually running. The average energy consumption of advisors during the execution of the track was 659.43 kcal. It is concluded that physical activity performed was predominantly aerobic, intensity medium, but the supervisor needs to constantly anaerobic substrate, due to constant changes of pace and intensity. Key words: Orientation, Energy expenditure, Counselors.

Introduction: Exercise improves insulin sensitivity in healthy, obese and diabetic patients 1 and 2, by improving glucose uptake in muscle and decreased hepatic glucose production, these processes occur via different intracellular signaling pathways. Assist with the welfare of the patient, the amino acids leucine is the most effective in stimulating protein synthesis, reduce proteolysis and directly and indirectly stimulate the synthesis of insulin. Objective: The objective of this study was to evaluate blood glucose after strength training, and evaluate the lipid values and body composition after the use of leucine in overweight patients. Materials and Methods: The subjects were three female patients: (A), (B) and (C), where he was asked to take a full lipid profile and measured blood pressure, measured height and weight and skinfold thickness for realization of the fat percentage of body composition and verification. These parameters were evaluated at the end of the study for comparison. Then the glucose was measured before and after exercise of force. 1 x per week for 3 weeks. Results: Both for patient A, B and C, anthropometric data (weight, BMI, fat percentage, waist, hip) and lipids (total cholesterol, HDL, LDL, VLDL, triglycerides) showed no reliable differences before and after the search, and the blood glucose before and after exercise of force. Blood pressure remained constant. Discussion: The leucine can mobilize fat in certain fractions of cholesterol metabolism and respecting the individuality of each patient. Conclusion: The glucose may be reduced after strength training if there not is gluconeogenesis and leucine did not change noticeably body composition, but reduced some lipid levels. Key words: Leucine, Glucose, Exercise of force, Body composition.

The habit of practising physical exercises has been consolidated in good part of the population in recent years, especially within the academies. Consequently the quest for a "perfect body" has led to indiscriminate use of nutritional supplements. Therefore the goal of the research was to examine the profile of the consumption of supplements in bodybuilding practitioners of an Academy of Lajeado-RS. It is a descriptive research. The sample was of 20 users of nutritional supplements (85% of masculine gender and 15% of the female gender). The instrument used was a quiz with question 13 concerning the purpose of the study objective. The results were more expressive: 55 percent of the respondents have less than a year of practice of bodybuilding, 50% have it as a source of Physical Education Professional indication, 40% use supplements with proteins and amino acids and has more muscle mass gain goal. The marketing and the availability of supplements grow abruptly, but have few benefits of using scientific evidence. Every effort should be concentrating on the nutritional education of the general public, about the consumption of supplements and their effects in the body to ensure greater security for those people who use them. Key words: Nutritional supplements, Exercise, Sports nutrition.

Introduction: Important studies have sought to highlight the benefits of physical exercise and a healthy food, associated to health and wellness. Objectives: verify eating habits, level of habitual physical exercise and anthropometric profile of the residents of a condominium Curitiba PR. Materials and Methods: A cross-sectional study, the sample consisted of 27 individuals, 13 men and 14 women, residents completed a questionnaire about eating habits and usual level of exercise with questions taken from Brasil (2011), and were subjected to measures of body weight, height, and circumference, waist, hip and abdomen. Results: The residents had a BMI of 25.88 (± 4.10), WHR 0.90 (± 0.10) for men and 0.82 (± 0.10) in women, the BAI was 24, 6 (± 3.10) in men and 29.83 (± 4.30) in women and CI of 1.20 (± 0.10) in men and 1.08 (± 0.08) in women. As for eating habits 74.1% (n = 20) of residents are currently trying to eat more healthily and 66.7% (n=18) practice physical exercise. Discussion: Observed indexes overweight and obesity among residents, the Body Adiposity Index was included in research to reinforce this reality. Conclusion: the residents of the condominium have good eating habits, proper behavior as has the practice of physical exercises, however anthropometric indices showed that although all knowledge, does not seem to be sufficient to maintain a normal body weight. Key words: Food, Physical exercise, Anthropometry, BAI.

The purpose of the research was to evaluate the feeding habits, in order to classify the BMI and analyze the type of food ingested by the gym goers. The study was performed with 50 gym goers of both sexes in the age group of 20 to 30 years, which worked out for more than 6 months. A questionnaire was applied containing a nutritive anamnesis, being that the obtained results were that 20% were feminine and 80% were masculine, and analyzing the BMI, 44% eutrophic, 40% overweight and 16% level I obesity, keeping in mind that this value may have been influenced by the bodily mass index. The diet group that had the greatest percentage of acceptance (1 – 3 times/day) was the cereals, which should be above the 4 times/day. Among the interviewed, 84% use or have already used supplements, and the most utilized supplements by them were malt dextrin, albumin, whey protein, creatine and BCAA. We conclude that after evaluating the feeding habits of gym goers, we observe that the daily consumption of the diet groups were consumed up to 3 times a day. After evaluating these habits it was possible to observe that a high consumption on supplements occur among the practitioners of physical activity. Therefore, to us it seems necessary the implementation of nutrition education programs, with the support of a nutritionist, acting with further professionals in the gyms or places where physical exercises are practiced for the appropriate guidance of feeding and nutrition.
