          Abstract

          ABSTRACT Objective: To describe the supplements used by adolescents in gyms in the city of São Paulo and the factors related to their use. Methods: Participants were 1,012 adolescents of both sexes, aged between 13 and 18 years old, all of them regular regulars at gyms in the city of São Paulo. For data collection, a questionnaire was used to identify the main supplements consumed by adolescents. The chi-square test was used to verify possible associations with a significance of p<0.05. Results: The use of supplements was more frequent in the age group between 16 and 18 years, in the socioeconomic level B, and the use of these supplements was higher as the time of exercise in the gym was longer (>12 months). The amount of exercise modalities practiced in the gym was inversely associated with the use of supplements. Male adolescents consumed significantly more supplements than females, and Physical Education professionals, friends and parents were the ones who most influenced adolescents to use supplements. The main supplements used by the boys were carbohydrate gel (90.9%) and hypercaloric (94.5%). In girls it was fat burner (55.0%) and vitamins and minerals (50.0%). Conclusion: The use of supplements was common among adolescents who exercise in gyms in São Paulo and the indication was made by physical education professional.

          RESUMO Objetivo: Descrever os suplementos utilizados por adolescentes em academias da cidade de São Paulo e os fatores relacionados à sua utilização. Métodos: Participaram 1.012 adolescentes de ambos os sexos, com idade variando entre 13 e 18 anos, sendo todos frequentadores regulares de academias de ginástica na cidade de São Paulo. Para coletada de dados, foi utilizado um questionário com objetivo de identificar os principais suplementos consumidos pelos adolescentes. Utilizou-se o teste Qui Quadrado para verificar possíveis associações com significância de p<0,05. Resultados: O uso de suplementos foi mais frequente na faixa etária entre 16 e 18 anos, no nível socioeconômico B, e, o uso desses suplementos foi mais alto a medida que o tempo de prática de exercício na academia foi maior (>12 meses). A quantidade de modalidades de exercício praticada na academia esteve inversamente associada ao uso de suplementos. Adolescentes do sexo masculino consumiram significativamente mais suplementos do que o sexo feminino, e, os profissionais de Educação Física, amigos e pais foram os que mais influenciaram os adolescentes para o uso de suplementos. Os principais suplementos utilizados pelos meninos foram o gel de carboidrato (90,9%) e hipercalóricos (94,5%). Nas meninas foram o fat burner (55,0%) e vitaminas e minerais (50,0%). Conclusão: O uso de suplementos foi comum entre adolescentes praticantes de exercícios em academias de São Paulo e a indicação foi feita basicamente por profissionais de educação física.

          American College of Sports Medicine Joint Position Statement. Nutrition and Athletic Performance.

          It is the position of the Academy of Nutrition and Dietetics, Dietitians of Canada, and the American College of Sports Medicine that the performance of, and recovery from, sporting activities are enhanced by well-chosen nutrition strategies. These organizations provide guidelines for the appropriate type, amount, and timing of intake of food, fluids, and supplements to promote optimal health and performance across different scenarios of training and competitive sport. This position paper was prepared for members of the Academy of Nutrition and Dietetics, Dietitians of Canada (DC), and American College of Sports Medicine (ACSM), other professional associations, government agencies, industry, and the public. It outlines the Academy's, DC's and ACSM's stance on nutrition factors that have been determined to influence athletic performance and emerging trends in the field of sports nutrition. Athletes should be referred to a registered dietitian/nutritionist for a personalized nutrition plan. In the United States and in Canada, the Certified Specialist in Sports Dietetics (CSSD) is a registered dietitian/nutritionist and a credentialed sports nutrition expert.

              International society of sports nutrition position stand: diets and body composition

              Position Statement: The International Society of Sports Nutrition (ISSN) bases the following position stand on a critical analysis of the literature regarding the effects of diet types (macronutrient composition; eating styles) and their influence on body composition. The ISSN has concluded the following. 1) There is a multitude of diet types and eating styles, whereby numerous subtypes fall under each major dietary archetype. 2) All body composition assessment methods have strengths and limitations. 3) Diets primarily focused on fat loss are driven by a sustained caloric deficit. The higher the baseline body fat level, the more aggressively the caloric deficit may be imposed. Slower rates of weight loss can better preserve lean mass (LM) in leaner subjects. 4) Diets focused primarily on accruing LM are driven by a sustained caloric surplus to facilitate anabolic processes and support increasing resistance-training demands. The composition and magnitude of the surplus, as well as training status of the subjects can influence the nature of the gains. 5) A wide range of dietary approaches (low-fat to low-carbohydrate/ketogenic, and all points between) can be similarly effective for improving body composition. 6) Increasing dietary protein to levels significantly beyond current recommendations for athletic populations may result in improved body composition. Higher protein intakes (2.3–3.1 g/kg FFM) may be required to maximize muscle retention in lean, resistance-trained subjects under hypocaloric conditions. Emerging research on very high protein intakes (>3 g/kg) has demonstrated that the known thermic, satiating, and LM-preserving effects of dietary protein might be amplified in resistance-training subjects. 7) The collective body of intermittent caloric restriction research demonstrates no significant advantage over daily caloric restriction for improving body composition. 8) The long-term success of a diet depends upon compliance and suppression or circumvention of mitigating factors such as adaptive thermogenesis. 9) There is a paucity of research on women and older populations, as well as a wide range of untapped permutations of feeding frequency and macronutrient distribution at various energetic balances combined with training. Behavioral and lifestyle modification strategies are still poorly researched areas of weight management.
