The objective of the present study is to evaluate and compare the effect of a nutritional intervention between adolescent and adult. In a before and after quasi-experimental clinical study, 32 athletes (21 adults, age range 20–32 years; 11 adolescents, age range: 12–19 years) participated in a nutritional counselling consisting of four consultations separated by an interval of 45 to 60 days. The athlete’s eating behaviour, body composition and nutrition knowledge were evaluated at the beginning and at the end of the protocol. Both groups increased lean body mass and nutritional knowledge. Adolescents increased their mid-arm muscle circumference and improved meal frequency, and daily water intake. Athletes of both groups improved their ingestion of vegetables and fruits and decreased the ingestion of sweets and oils. Adolescents showed a higher prevalence of individuals that remained within or approached to the recommendations of sweets. This is the first study to evaluate and compare the effect of a nutritional intervention between adolescent and adult athletes body composition, eating behaviour and nutritional knowledge. The nutritional counselling has been effective in promoting beneficial changes on the athlete’s eating behaviour, nutritional knowledge and body composition, however, some healthy changes were only experienced by adolescents, especially in the frequency of meals and the intake of sweets.

Nutrition education is one of the factors that may help to promote behavior change and therefore may improve the dietary habits of adolescent soccer players. However, information about the relationship between nutrition knowledge (NK) and the dietary behavior of these athletes is scarce. The purpose of this study was to evaluate the eating habits of adolescent soccer players and analyse the correlations among dietary intake and NK. Seventy-three Brazilian adolescent soccer players (aged 14–19 years), from four professional clubs, underwent anthropometric evaluation and completed 3-day food records. Misreporting of energy intake was evaluated and the dietary intake data were energy-adjusted and compared with recommendations for athletes and dietary reference intakes. The athletes also answered a questionnaire about barriers for healthy eating and a nutrition knowledge test divided into three sections: Basic Nutrition Knowledge (BNK), Sports Nutrition Knowledge (SNK), and Food Pyramid Nutrition Knowledge (FPNK). The participants showed a low NK (54.6%) and an inadequate intake of fruits, vegetables, dairy, carbohydrates, and micronutrients. A positive correlation was found between the ingestion of phosphorus and FPNK as well as among calcium and both SNK and Total NK (). Sodium intake was negatively correlated with all categories of the NK test (). The adolescents reported that the principal barriers for adopting a healthy diet were the lack of willpower and a busy lifestyle. In this context, nutrition education is recommended and should also provide practicable healthy eating goals according to athletes´ lifestyle as well as target motivational barriers to increase adherence.
Introduction: an evaluation of an athlete’s dietary intake may help to understand the dietary inadequacies that are found in athletes and how other factors, such as nutritional knowledge and age, might also influence their food behavior. Objective: to evaluate and compare the dietary intake and the nutrition knowledge between adult and adolescent table tennis players. Method: forty-two competitive athletes (25 adolescents and 17 adults) responded to two non-consecutive 24-hour recalls and a validated nutritional knowledge questionnaire. Numerical and categorical variables were compared between groups by using independent-sample Student’s t-tests and Pearson’s Chi-square test, respectively. Results: the adolescents showed lower intakes and higher inadequacies in the ingestion of micronutrients (p < 0.05). Most of the adolescents rated their dietary quality as excellent/good, while a higher prevalence of the adults rated their dietary quality as being poor/very poor (p < 0.05). The nutritional information sources that were most used by the adolescents and the adults were their parents and the internet, respectively. The between-group analyses showed that the adults had a higher nutrition knowledge than the adolescents (p < 0.05). Conclusions: the athletes showed poor dietary habits, low levels of nutritional knowledge, as well as the use of low quality nutritional information sources. The adolescents showed a higher prevalence of nutrient inadequacies, lower nutritional knowledge levels, as well as a worse self-perception of dietary quality than the adults.

Este estudo teve como objetivo analisar o conhecimento em nutrição de instrutores de musculação do município de Aracaju/SE. Os participantes eram compostos por 111 professores e 58 estagiários e responderam um questionário com perguntas sobre alimentação, orientação nutricional e um teste sobre conhecimento em nutrição. 65% dos instrutores relataram dar orientação nutricional aos seus alunos. Os participantes responderam corretamente a 59,7% das questões do teste de conhecimento nutricional. Os instrutores de forma geral tiveram maiores percentuais de acerto nas questões sobre Nutrição geral, do que Nutrição esportiva.
