“…Comparisons with other articles are di cult due to the low number of studies performed in adolescent athletes and the variety of methods applied. Nonetheless, to our knowledge, NK scores have ranged from 36.9% to 77.6% in teen athletes [7,8,[37][38][39][40][41][42][43].…”

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 (p<0.05). Sodium intake was negatively correlated with all categories of the NK test (p<0.05). 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.

“…Comparing our data with studies performed in sports populations 28,29 is difficult, considering the sports are not similar and do not cover the entire range of ages analyzed by us. However, in comparison with values found in adolescents who play indoor soccer 20 (41.67% of average adherence) and swimmers 29 (36% high adherence), the percentages of average and good adherence of adolescent gymnasts in our study were superior in all cases and similar to the only study with rhythmic gymnastics adolescents 30 , in which 52.2% of gymnasts presented a high adherence to the MD.…”

Introduction: Eating habits are one of the underlying aspects in rhythmic gymnastics as a sport with an aesthetic component. Objective: To evaluate adherence to the Mediterranean diet (MD) in girls and adolescents who perform rhythmic gymnastics, and the relationship of this adherence with Body Mass Index (BMI) and waist circumference. Methods: A prospective, descriptive comparative cross-sectional study with the participation of 221 gymnasts aged between 7 and 17 years. Adherence to the Mediterranean diet was analyzed using the KIDMED test. The waist circumference, height and weight of each gymnast were measured and the BMI calculated. Results: 41.63%, 52.94% and 5.43% of the total sample exhibited high, medium and low adherence, respectively, to the Mediterranean diet. The Mann-Whitney U test indicated significant differences in the rate of adherence to the Mediterranean diet between the two age groups, U = 5007.0, p = .016, r = .162. The adolescent gymnasts had greater adherence than the younger gymnasts. The total sample showed a positive correlation of the rate of adherence with weight (Rho = .143, p = .034), BMI (Rho = .152, p = .024) and waist circumference (Rho = .180, p = .007). Conclusions: The eating habits of adolescent gymnasts with regard to the Mediterranean diet are healthier than those of the younger gymnasts. All participants had normal BMI values. The KIDMED values of the total sample were related to weight and BMI. The high percentages of younger gymnasts with mean adherence to the MD evidenced the need to approximate their eating habits with Mediterranean standards.

ABSTRACT:Little data exists regarding nutritional knowledge and hydration in adolescent swimmers. The aim of this study was to assess the level of nutrition and hydration knowledge and to describe the fluid balance in adolescent swimmers during training. A study was carried out with a cross-sectional descriptive part and a longitudinal part with repeated measurements over five swimming sessions. Eighty-six adolescent swimmers completed a questionnaire to assess their sport nutrition and hydration knowledge. Fluid balance and urine hydration markers were studied during training.Swimmers showed a limited nutrition knowledge (33.26 % ± SD 12.59) and meagre hydration knowledge (28.61 % ± SD 28.59). Females showed lower scores than male swimmers in nutrition and hydration knowledge. Based on urine specific gravity, swimmers started the training close to the euhydrated threshold (1.019 g/mL ± SD 0.008). Although urine specific gravity and urine colour were reduced after the training, there were minimal changes in body mass (-0.12 Kg ± SD 0.31). Sweat loss (2.67 g/min ± SD 3.23) and the net changes in the fluid balance (-0.22 % ± SD 0.59) were low. The poor knowledge in nutrition and hydration encountered in the swimmers can justify the development of a strategy to incorporate nutritional education programmes for this group. Body water deficit from swimming activity seems to be easily replaced with the water intake to maintain hydration. After the training, the urine of swimmers was diluted regardless of their water intake. Dilution of urine did not reflect real hydration state in swimming.
