Adolescents aged 11-14 years (n 326), belonging to organized sports federations in the Federal District, Brazil were interviewed. Subjects (n 107) provided four non-consecutive days of food consumption and 219 subjects provided two non-consecutive days of intake. The objective was to assess their nutrient and water intake according to dietary reference intake values and their energy and macronutrient intake by sex and sports groups they were engaged in: endurance, strength-skill or mixed, according to the guidelines established by the American College of Sport Medicine (ACSM). Dietary data were corrected for intra-individual variation. Total energy expenditure was higher among endurance athletes (P,0·001) following their higher training time (P,0·001) when compared to adolescents engaged in strength-skill or mixed sports. Total energy intake was only significantly higher among endurance-engaged females (P¼0·05). Protein intake of males was above the guidelines established by the ACSM for all sports groups. All male sport groups fulfilled the intake levels of carbohydrate per kg body weight but only females engaged in endurance sports fulfilled carbohydrate guidelines. Intakes of micronutrients with low prevalence of adequate intake were: vitamins B 1 , E and folate, magnesium and phosphorus. Few adolescents (, 5 %) presented adequate intake for calcium, fibre, drinking water and beverages. For micronutrients, prevalence of adequacies were lower for females than males, except for liquids and water. Nutrition guidance is needed to help adolescents fulfil specific guidelines of macronutrient intake for their sports and to improve their intake of micronutrients and water. Special attention should be given to female adolescent athletes. The bodily changes induced by adolescence increase energy requirements. This higher requirement is not only necessary to maintain health and promote growth and sexual maturation but also to provide the energy expended in physical and intellectual activities (1) . The regular practice of sport activities during adolescence can bring health benefits to these individuals. However, the physical activity will increase the energy expenditure and consequently the energy intake needs as well as the need for some nutrients (2) . Roemmich et al. (3) analysed adolescents who practised weight-control sports, such as wrestlers and gymnasts, and found that these individuals presented nutrient intake 50 % below their requirements. These cases of undernutrition among adolescents may lead to changes in growth and sexual maturation. Additionally, these authors justify that, for most adolescents, what impairs their growth and pubertal development is nutrient deficiency, not intense physical activity. In Brazil, the Ministry of Health has launched the National Policy of Health Promotion, which includes the promotion of physical activity and sports practice (4) . In schools and sports clubs adolescents are also encouraged to engage in sport activities as a means of physical education and talent selection ...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
