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.

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.

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.

Recent work has observed additional effects of combined aerobic and resistance exercise (RAS) on glycemic control relation to aerobic or resistance exercise alone in the older adult type 2 diabetes. But even the few studies assessing the behavior mode (RAS) in blood glucose in short term or long (DM2). The purpose of this review. And compare the behavior of the effects (RAS) in the short or long in glycated hemoglobin (HbA1c), body mass index (BMI), body weight and maximal oxygen uptake (VO2max), in adult patients more with old (DM2). In the survey included nine articles related to the subject matter, based electronic data: Scielo, NCBI, Pubmed. The results indicated significant reduction in HbA1C in both studies, both more inclined to work to contain a greater volume weekly exercise. There was also a significant increase in VO2max in virtually all studies also increase muscle mass and strength, especially in studies with (RAS) longer. The BMI and body weight decrease slightly, which suggest have occurred by the increase in lean body mass. In conclusion (RAS) short-or long-term care promote improvement in muscle skeletal function and aerobic capacity, causes metabolic adjustments that make more efficient glycemic control patients older adults (DM2).

Introduction: There is debate today about the risks of an inadequate diet: saturated fat, carbohydrates and salt, but also the low frequency of meals, but rather deepens the evil effects of fractionation of meals for health in the medium and long. Objective: This study proposes to conduct a literature review about what has been published about the effect of splitting meals in reducing cholesterol in humans. After careful bibliographical study of several authors found that there are several publications addressing the subject searched, but in Brazil the issue is still not as discussed as in other countries. This fact is due to the small number of national publications found. Literature review: The review showed that in most studies, the meal frequency around 6 meals a day leads to a lower daily energy intake and a regular control of cholesterol synthesis due to a regular insulin secretion. Thus, just by changing the frequency of food intake to a regular attendance has been a reduction in total cholesterol and LDL. It was also seen that the meal fraction is extremely important for the prevention and treatment of persons with diabetes since insulin sensitivity is directly related to their secretion rate. Conclusions: It is concluded that the correct fractionation of meals is an important factor in lowering cholesterol and preventing cardiovascular disease, but still it is necessary to make further studies in order to achieve results more concise. Key words: Meal frequency; Cholesterol; Insulin.

This study aimed to assess the nutritional profile of middle-distance runners. Fifty-six middle-distance runners (age: 22.0±5.4 years; weight: 63.1±5.8 kg; height: 174.7±5.8 cm) participated in the study. They had 7.4±4.8 years of athletic experience and trained 8.1±1.7 sessions per week. Nutritional data were obtained through a semiquantitative food frequency questionnaire created by the Nutritional Epidemiology Department of the Faculty of Medicine, University of Porto, Portugal. The conversion of foods in nutrients was carried out through the Food Processor Plus program, version 7.0. Daily average energy intake was 3014±913 kcal (1497-4900), corresponding to the following relative nutrient consumptions: carbohydrates 54.0±6.7% (6.5±2.3 g.kg-1.day-1), fat 29.5±5.0% (1.6±0.6 g.kg-1.day-1) and protein 16.4±2.9% (1.9 ±0.6 g.kg-1.day-1). Vitamins D and biotin ingestion was under the recommendations. Macro- and micromineral consumption exceed the recommendations. The mains results point out to a low carbohydrate intake, under the recommendations for endurance athletes. Protein intake is excessive. Fat as well as vitamin (with exception of vitamins D and biotin) and mineral intakes, are adequate. A significant percentage of the subjects had very low energy intakes what can negatively affect performance and health.

Was conducted a cross-sectional study, where the research subjects were dancers of a ballet school in Caxias do Sul, RS, with the aim of relating self-perception and anthropometric data with food intake of adolescent dancers. To assess the nutritional profile was made an interview with straightforward questions about eating habits and an assessment of body self-perception, also an anthropometric assess (weight, height, body mass index for age and stature for age). After, it was applied a 24 hour recall. It was observed that most dancers evaluated were eutrophic, while 57,1% wanted to lose weight. They worry about the weight in a percentage of 82,1%. There is a lower daily energy and some nutrients intake compared with the reference age group. The data suggest that adolescent dancers are susceptible to poor eating habits in order to get leaner bodies. Key words: Dance, Nutrition, Body image.

Purpose: to demonstrate the VO2max and the fat percentage of the athlete, as well as the physiological load of the football through the distance covered. Methodology: a systematic revision was used as the methodology. The results: The average of the ratio of rest – low-intensity activities – high-intensity activities is 3:16:1, suggesting that the biggest part of the energetic demand is aerobic, however due to intermittent activities, it is important to have an harmonic development between aerobic and anaerobic metabolisms. The amount of AGL increases during a football match, the depletion of glycogen throughout the game is excessively high, the supplies of phosphocreatine provide a considerable amount of the energy necessary for the short-lived high-intensity activity and the amino acids serve as an auxiliary energy source. The VO2max and the LAN are important factors for the body to tolerate the long duration of the game, the amounts of VO2max found were between 52,67ml.kg.min-¹ and 63,75ml.kg.min-¹, and the amounts of vLAN were between 12,66km/h and 14,8km/h. The fat excess is and extra weight, that compromises the physical performance, the values found for the fat percentage were between 7,3% and 12,6%. The distance covered transmits the general idea of the physiological load applied by the player; the values found were between 8638m and 11000m. The efficiency of the athletes can be better demonstrated by the distance covered at a high speed, the values found were between 437m and 690m. Conclusion: a greater knowledge about the motor and physiological specificities of the sport will ease and optimize the physical periodization, besides improving the specificity of the daily training.

Supplementation with branched chain amino acids has been disseminated widely among practitioners of physical activities. Studies suggest the development of central fatigue during activity, its correlation brain serotonin and leucine. Purpose of this study was to evaluate through tests of open field and elevated plus-maze, the behavior of rats supplemented with three different doses of leucine. Wistar rats were divided into groups: control (C), leucine 0.30mM/100g (L0,30), 1.25mM/100g (L1,25) and 5mM/100g (L5), supplemented via oral gavage. For statistical analysis, variance followed by Tukey test (p<0.05). The exploratory behavior was observed that rats L0,30 did not differ from C and the groups L1,25 and L5, showed a reduction. In the elevated plus-maze group C compared with L0,30 and L1,25 did not get the difference, the L5 group differed from the others. The results suggest the existence of physiological and behavioral changes related to supplementation with leucine. Key words: Leucine, Fatigue, Motor Activity, Behavior

Introduction: Caffeine is one of the most used stimulant drugs in the world. This is an alkaloid belonging the methylxanthine family, whose formula is 1,3,7-trimethylxantine. When consumed in low dosages (2mg/Kg), caffeine increases wakefulness, decreases dorwsiness, relieves fatigue, increases the cathecolamine release, the heart rate, the diuresis and speeds up the metabolism. Due your several properties, your ergogenic effect has been studied a lot. It’s believed that this effect is associated with the possibility of caffeine powered the athletes performance, retarding the fatigue through mechanisms controlled by nervous system. Purpose: The purpose of this study was to review and discuss the related research about this subject in order to compare the effects of caffeine supplementation in different exercises, doses and used protocols. Conclusion: Caffeine has your ergogenic effect comproved in several exercises, with less effectiveness in high intensity and short term. The most potent dosage varies between 3-6mg/Kg. Its effects are better explained for the adenosine antagonism while other mechanisms are still contradictory. Non-users caffeine and high trained individuals present better results. Associated with carbohydrate it promotes increased performance when ingested during or post-exercise and combined with creatine, this last is impaired. Due the variety actions and tissues that it can act, caffeine needs more studies to improve the knowledge about your ergogenic potential. Key words: Caffeine, Fatigue, Performance, Ergogenic effect.

Objective: The objective of this review is to critically analyze the studies on the effect of supplementation and / or antioxidant diet on oxidative stress induced by exercise. Literature Review: Selected works from 1992 to 2010, totaling 48 articles (43 international, 05 national). The systematic review demonstrated that there are few studies showing positive results with antioxidant supplementation on oxidative stress induced by exercise. Improper use of antioxidant supplements can prevent necessary adaptations and beneficial exercise and interfere with hormesis. Conclusion: Physical exercise can lead to oxidative stress, but the overuse of antioxidant supplements to try to control it may interfere with adaptations and not necessary. Thus long-term studies on the actual need additional antioxidants to practitioners of physical exercise are necessary and extremely important, trying to establish parameters for the use of supplements and protocol standards.

The basis for achieving the minimum demand required, both energetic and nutritional, for the routine day to day work and of a the practice of sports is the realization of a balanced diet. In subjects with heavy work routines that also practice sports nutrition becomes even more important. The analysis of anthropometric profile enables a proper meal planning, thus impacting on the improvement of the performance in both of the activities. The study aimed to evaluate the anthropometric and nutritional profile of garbage collectors that were also training for a half marathon. We evaluated five street sweepers with average age, weight, height, BMI, of 30.8% G ± 5.67 years, 68.6 ± 13.40 kg, 1.73 ± 0.11 m, 22.66 ± 242 kg / m², 9.03 ± 3.21% respectively. The averaged energy consumption were (EC) 2557.13 ± 326.08 kcal and the average caloric intake for this group is 3872.47 ± 756.56 kcal, in the macronutrients evaluation of the garbage collectors the consumption were of 5.75 g / kg and 60.36% of the EC-CHO, 1.6 g / kg and 17.08% for PTN, 0.96 g / kg and 22.55% of LIP, in accordance with the recommendations of the 2009 SBME guideline. It can be concluded that the energy consumption of this population is less than the daily necessities, but the intake of macronutrients and anthropometric profile of the recommendations are appropriate.

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.

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.

Introduction: Glutamine is the most abundant free amino acid in plasma and muscle tissue. It is used in high concentrations in rapidly dividing cells, intestinal cells, to provide energy. In strenuous exercise, it is observed that the consumption of glutamine exceeds the capacity to synthesize body, related to increased levels of the hormone cortisol, which in competitive situations, it may be an indicator of stress. Objective: To evaluate the action of glutamine in reducing the stress caused by release of cortisol in prolonged exercise and intensity. Materials and Methods: We used five volunteers of both sexes, aged between 30 and 40 years, regular practitioners of exercise a year, often at least 5 times a week. The participants underwent a blood test in the morning to check cortisol levels before starting the study and after study completion. The experimental group supplemented for 30 days with 5g glutamine in jejum and 5g after exercise. Results: The group who supplemented with glutamine showed lower levels of cortisol than the group not supplemented. Discussion: Numerous studies have demonstrated a significant decrease of plasma and tissue glutamine during and after strenuous exercise and prolonged, but the effects of exercise on glutamine metabolism have not been fully elucidated. Conclusion: More studies are needed to evaluate the effectiveness of glutamine in practitioners of high-intensity exercise in reducing the stress caused by the release of cortisol.

Objective: To evaluate the change in body fat in a woman, supplemented with caffeine and practitioner of Power Jump intermittent exercise in a gym. Materials and methods: We conducted a case study of a woman, 40 years, 63 kg, 1.58 meters, healthy, trained, practicing aerobic exercise modality Power Jump, 3 times a week. We collected measurements of weight, height, waist circumference and skinfold thicknesses to be calculated% fat. Were administered 3 mg / kg of caffeine one hour before exercise, 3 times a week for 30 days. Results: We found a decrease in fat percentage, body weight and waist circumference, reported an improvement in the mood for the exercises and, as a side effect of insomnia. Discussion: In agreement with this study, several authors found a decrease in body fat in athletes and exercise supplemented with caffeine, assuming factors such as the release of catecholamines, the economy of muscle glycogen, increased lipolysis, by still not well understood, including the fact that caffeine is adenosine receptor antagonist, which usually block the lipolysis. Conclusion: Thus, supplementation with 3 mg / kg of caffeine, along with the practice of intermittent exercise Power Jump, resulted positively in reducing weight, waist circumference and body fat.

Objective: The objective of this study was to evaluate changes in plasma osmolality after the practice of indoor cycling. Materials and Methods: The study included 11 volunteers, male, aged between 18 and 30 years, not practitioners of indoor cycling, apt to performing physical exercise. The volunteers were submited to practice indoor cycling, during 60 minutes and with intensity between 65 and 80% of maximum heart rate. Results: The results suggest that 60 minutes of exercise performed in the intensity between 65 and 80% of maximum heart rate is not sufficient to bring about significant changes in plasma osmolality. Discussion: The assessment of plasma osmolality despite being the most reliable method to assess hydration levels, appears to be the best method to assess acute changes in hydration levels and, therefore, it is believed that the changes in mass represent the body more effectively and efficiently in this case. Conclusion: We conclude with this study that the practice of indoor cycling with volume and intensity for 60 minutes between 65 and 80% of maximum heart rate , does not significantly alter plasma osmolality.
