Introduction: Adverse nutritional environment during the fetal period, lactation and infancy may favor occurrences of chronic diseases in the offspring. Objective: Analyze the effects of ingestion of a westernized diet on growth parameters, biochemistry, and food preference in the offspring of mothers fed a hypocaloric diet with or without physical activity. Methods. 40 rats were divided into 2 groups according to the diet: Control (n=20) and hypocaloric (n=20). The litters were composed of 8 pups, and at weaning 1 male pup from each litter was selected to compose new groups according to the westernized diet (C or H) and physical exercise (E and NE) composing the groups: CNE, CE, HNE and HE. Swimming was carried out from the weaning to the 62nd day of life and evaluated: Body weight, abdominal fat, biochemical parameters, food consumption and OGTT. Data expressed as mean, standard deviation, p<5% Results. Hypocaloric maternal diet caused 28% reduction in the weight of the pups at weaning; and the intake of the westernized diet post-weaning diet by the hypocaloric group equaled the groups in weight and length but did not modify food preference. Dyslipidemia was observed in HE and reduced body mass in CE compared to CNE at 63 days of life (CNE=306,1Â±57,8g; CE=235,5Â±31,5g; HNE=279,9Â±33,6g; HE=243,4Â±38,5g, p=0,0038). Conclusion. calorie restriction followed by westernized diet and exercise altered lipemic parameters, did not cause changes in dietary preference, and physical exercise reduced body mass in those fed a control diet before weaning, but not those fed a low-calorie diet before weaning.

低热量饮食与西式饮食在运动或非运动年轻大鼠中对代谢和食物偏好之间的相互作用

EnglishIntermittent fasting (IF) and daily calorie restriction (DCR) are nutritional strategies that have been widely adopted and compared with each other. This paper aims to compare the effects of IF and DCR on the alteration of biochemical markers and body composition. The PRISMA recommendation was used for the elaboration of the work, and 20 randomized clinical trials were included in the qualitative synthesis. There were no differences between IF and DCR in six studies evaluating blood glucose; four studies evaluating triglycerides; six studies evaluating insulin; all studies evaluating total cholesterol, homocysteine ​​and glycated hemoglobin; four studies that evaluated LDL cholesterol; five studies that evaluated HDL cholesterol; two studies that evaluated HOMA-IR; three studies that evaluated leptin; six studies that evaluated body weight; three studies that evaluated lean mass; and four studies that evaluated fat mass. There was an increase in the IF group for two studies evaluating weight loss recovery and two studies evaluating post-intervention caloric intake. Most studies investigating ghrelin found a decrease in IF. 19 included studies had a high risk of bias. Three systematic reviews found results similar to those found in this study on body weight change and contradictory results on insulinemia change. There seems to be no difference between IF and DCR in improving most of the parameters studied. portuguesO jejum intermitente (JI) e a restricao calorica diaria (RCD) sao estrategias nutricionais que vem sendo amplamente adotadas e comparadas entre si. Este trabalho tem como objetivo comparar os efeitos do JI e da RCD na alteracao de marcadores bioquimicos e da composicao corporal. Utilizou-se a recomendacao PRISMA para a elaboracao do trabalho, e 20 ensaios clinicos randomizados foram incluidos na sintese qualitativa. Nao observou-se diferencas entre JI e RCD em seis estudos que avaliaram glicemia; quatro estudos que avaliaram triglicerides; seis estudos que avaliaram insulinemia; todos os estudos que avaliaram colesterol total, homocisteina e hemoglobina glicada; quatro estudos que avaliaram LDL colesterol; cinco estudos que avaliaram HDL colesterol; dois estudos que avaliaram HOMA-IR; tres estudos que avaliaram leptina; seis estudos que avaliaram peso corporal; tres estudos que avaliaram massa magra; e quatro estudos que avaliaram massa gorda. Observou-se aumento no grupo JI para dois estudos que avaliaram recuperacao de peso perdido e dois estudos que avaliaram o consumo calorico pos intervencao. A maioria dos estudos que investigaram grelina encontrou diminuicao em JI. 19 estudos incluidos apresentam alto risco de vies. Tres revisoes sistematicas encontraram resultados semelhantes aos deste trabalho na alteracao de peso corporal, e contraditorios na alteracao da insulinemia. Parece nao haver diferencas entre o JI e a RCD na melhora da maioria dos parâmetros estudados.

Creatine is a compound formed by the combination of the amino acids arginine, glycine and methionine and which has been showing positive benefits in physical exercise. From this, the objective was to investigate the action of creatine in the sports performance of strength and endurance. The work is a systematic review prepared with a careful selection of scientific articles, according to the PRISMA model. The articles were searched between August and November 2020, in the PubMed, Science Direct and Web of Science databases. The PICOT method (population, intervention, comparator, outcome and type of study) was used to define the question that led to this review. For the selection and eligibility of studies, inclusion and exclusion criteria were used. In all, 16 articles were selected, of which 6 were elected to compose the review. To ensure the methodological quality of the articles included, a classification tool was used, based on the Cochrane Library. With the studies, it was possible to observe the homogeneity in the samples, diversification in age, selection protocol, duration of studies, type of exercise and diversification in dosage. The researches analyzed showed that the time of use and the dosage of creatine reflected positively on the performance, increasing the percentages of maximum strength. Its use was more effective in amounts less than 5g/kg/day. Intensity exercises with short duration and short intervals between sets showed the best results associated with performance and performance. Further research on the use of creatine should be carried out in order to standardize the amount and time of use of the supplement.

There has long been an abusive increase in the consumption of nutritional supplements and drugs, which induce greater thermogenic action. The indiscriminate use of these products, without knowledge of their effects and their action, can compromise the quality of life of the individual, which can cause harm to health. The objective of the study was to verify through the literature the profile of the user who makes indiscriminate use of thermogenic, report the risks associated with this practice, describe the socioeconomic profile of users, and identify the side effects of these individuals. This is a systematic review study. The search for evidence was carried out in national and international databases: Scielo, PubMed and Google Scholar. If chosen, for select, only field research articles, carried out in human beings, which indicated the socioeconomic profile, the reason for use of supplements and indication of the same and review articles in the period from 2010 to 2020. 18 articles were used, in which a high demand from users of these products was observed, in 9 studies it was reported that the highest percentage of indication was by unprepared people and, in only one study, was related to the higher rate of consumption of these supplements by indication of qualified professionals. Thus, it was possible to conclude in the research contained in this review, that there was a high prevalence of individuals using indiscriminately thermogenic, in addition to their association with various side effects such as insomnia, aggressiveness, headache and, among them, cardiovascular diseases.

Introduction: Football is a sport world renowned; it involves intermittent and high-intensity exercises. The athleteâ€™s body can start metabolic acidosis when the energetic expenditure exceeds the supply, situation where it accumulates hydrogen, reducing the athleteâ€™s performance. The sodium bicarbonate (NaHCO3) has an extracellular function, buffer capacity of hydrogen ions. Mitigating or inhibiting acidification. Yet Beta-Alanine is precursor source of carnosine, buffering capacity substance of muscle acidosis. Both substances promote gain in the performance due to reducing fatigue. Objective: To investigate the effects of NaHCO3 and Beta alanine in the performance of football players. Materials and Method: This was a randomized clinical trial. The athletes were divided into 3 groups, where one of the groups, to the first group was given a placebo, the second one received 0,3g of NaHCO3/Kg bodyweight and to the third group 0,6g of beta alanine, ingested in the pre-workout diluted in â€œTangâ€ a kind of Juice powder, in individual bottle, forty minutes before the test. (Yo-Yo Intermittent Recovery Test). All the athletes were submitted to the three protocols on alternate days. Results: Took part in the study 14 players with an average age of 19,21 Â±0,70 years of, average weight 71,4 Â±6,6 kg, and stature between 1,73 Â±0,07m, the average BMI was 23,8 Â±1,56 kg/m2. The average of distance travelled to the groups was 2695,7 Â±620,8m, 2740,7 Â±528,2m, 2764,3 Â±632,6 m to placebo, NaHCO3, e beta alanine respectively. The beta alanine supplementation caused more discomfort to the athletes. Conclusion: It was not found significant differences related to the players distance travelled, in the comparison of the supplements used.

Introduction: Bodybuilders seek for muscle development and definition, and, for this, they have a specific training and nutrition routine. Objective: Evaluate the protein consumption by bodybuilding athletes and compare it to scientific evidence. Materials and Methods: This is a systematic review, with data search in the PubMed database on September 8, 2020. Articles published between the years of 2010 and 2020, and that evaluated the protein consumption by bodybuilding athletes, were considered eligible. Results: 284 references were found, of which 6 met the eligibility criteria, with a total of 128 male and 27 female athletes evaluated. The highest average protein consumption presented during the off-season phase was 4.3±1.2g/kg/day, and during the pre-contest it was 3.56±1.43g/kg/day. Discussion: Protein consumption was above the recommendations brought by ACSM (American College of Sports Medicine) and ISSN (International Society of Sports Nutrition), 1.2 to 2.0g/kg/day and 1.4 to 2.0g/kg/day, especially during the off-season phase, while normal values ​​are observed during the pre-contest phase. Conclusion: Studies indicate the absence of elements to affirm that the protein consumption above the recommendations may cause some risk to the athlete's health, however, the uncertain outcomes that renal overload can cause in the long run requires attention. Nutritional approaches are important to maintain a balanced diet, avoiding micronutrient deficiency.

Introduction: through a systematic review, the kinetic differences between animal and vegetable protein sources intake is shown, revealing the lesser digestibility and biodisponibility of essential amino acids in vegetable sources. It’s clear, though, that there are alternative ways of diversification and enrichment of such protein sources, assuring good nutritional and performance results in anabolism. Objective: evaluate the available data about the myths and differences between animal and vegetable protein sources. Materials and Methods: the research were conducted in the digital baselines Pubmed, Lilacs, Google Scholar, Scielo and Science Direct. The keywords used were hypertrophy, milk serum protein, vegetable protein source, animal protein source, muscle mass, muscle protein synthesis, muscle protein degradation and its Portuguese equivalents. Results: in the 6 articles studied, 465 healthy males received either an animal or vegetable-based diet, along with resisted training sessions. Discussion: the article has shown viability in anabolic increase with vegetable protein sources, like animal sources. Conclusion: Even though animal protein sources have advantage over vegetable sources, there are viable and similar options in vegetable protein, matching the performance of animal sources.

Dehydration is common among football players and is related to the reduction of sports performance. The objective of this study was to investigate the fluid losses induced by exercise and its association with fluid intake and performance in a field test, besides evaluating the knowledge about the hydration of the players. 20 male athletes from a professional football club in Fortaleza-CE participated in the study. The hydration status was evaluated from the percentage of weight loss on a training day, in which the water consumption of the athletes was recorded; And then applied the Yo-Yo Intermitent Recovery Test Level 1 (YYRT1). The prevalence of dehydration status was observed, with weight loss of 1.289 ±0.6193%. The mean water consumption was 1106.0 ±290.0 mL, and the mean distance covered in the YYR1 was 1040 ±394.2 meters. No significant correlation was found between the variables. The evaluation of the answers frequencies of the questionnaire showed a low level of knowledge in the subject approached. The findings in this study show the need to educate athletes about hydration as a way to avoid the reduction of performance and harm to the health of these individuals.

The consumption of dietary supplements has been increasing considerably in the country. The majority of consumers are male whose main source of indication is physical education professionals. Ingesting proteins in high amounts and for long periods can cause damage to the body, so it is important to identify risk groups in order to have an intervention if necessary. The aim of this study was to investigate the consumption of dietary supplements in male university students who practice bodybuilding. Fifty men, aged between 18 and 30 years, participated in the study and answered three questionnaires (sociodemographic, supplement consumption questionnaire and food frequency questionnaire). Of the 50 participants, 62% (n=31) did not consume supplements. The most consumed supplement was Whey Protein with 73.7% (n=14). The main source of indication for the consumption of supplements was the nutritionist with 44.4% (n=8), followed by self-indication with 27.8% (n=5). The main reason for the consumption of supplements was muscle gain (57.9%). When analyzing daily dietary frequency, participants who consume supplements ingest more meat, egg and soy protein, while those who do not consume supplements ingest more beans, milk and dairy products. Thus, those who make use of this resource on their own, it is possible that food education is an important strategy without them offering health risks.

Athletes, physically active people, and even those with chronic diseases, are increasingly looking for protein dietary supplements to get muscle mass growth. This study aims to verify the energy density, carbohydrates, proteins, sodium and essential amino acids in whey protein product labels available in physical and virtual stores of Brazilian market, qualitatively and quantitatively. This is a descriptive observational study: aminogram values were analyzed according to current Normative Instruction. We examined 75 labels of whey protein products with values. of macronutrients on labels. It was possible to quantify the total manufacturers with values within the recommended by the legislation. The data obtained are relevant to the population for choosing the products to be consumed. The results show that the communication on labels does not reach the minimum recommendation required by the legislation. Food supplements nutritional information must be simple and clear, enabling a better analysis of products quality, assisting health professionals and general public in their choices.
