Ingesta dietética y adherencia a la dieta mediterránea en un grupo de estudiantes universitarios en función de la práctica deportiva AbstractIntroduction: University students eating habits are moving away increasingly from the Mediterranean Diet (MD) Both nutrition and physical activity are essential to preserve an appropriate health. Objective: To compare food intake between athletes and sedentary University students. Subjects and methods: Cross-sectional study conducted on 49 students from the University of Valladolid. The weight and height were determined. The physical activity was evaluated by the GPAQ questionnaire. A food frequency questionnaire and a three-day food record were completed for the food intake analysis. The MD adherence was estimated by the Mediterranean Diet Score (MDS). Differences by sex and sport practice were analyzed with the T-test or with the Mann-Whitney-test. Statistical signifi cance was reached at p < 0.05. Results: All subjects had normal weight with no signifi cant differences depending on the sports practice. Women had a lower physical activity level than men. The diet in the whole sample was slightly hyperproteic, rich in fats and cholesterol, with an inadequate fat profi le and poor in carbohydrates and fi ber. Generally, the students covered the micronutrients requirements. There was a scarce consumption of fruits and vegetables, cereals, olive oil, fi sh and nuts; and an excessive intake of meat, butter, processed bakery foods, sweets, snacks and soft drinks. Around 50% of the sample had a low or very low MD adherence. Conclusion: The University student food pattern does not accomplish the nutritional objectives within the Spanish population and have a medium-low Mediterranean diet adherence, and there are no differences depending on the sports practice. ResumenIntroducción: la alimentación de los jóvenes universitarios se aleja cada vez más de la dieta mediterránea (DM). El binomio alimentación-actividad física es fundamental para mantener un adecuado estado de salud. Objetivo: comparar la ingesta en un grupo de estudiantes universitarios deportistas frente a otro que no realiza deporte habitualmente. Sujetos y métodos: estudio observacional transversal realizado en 49 voluntarios de la Universidad de Valladolid. Se determinaron peso, talla y actividad física (cuestionario GPAQ). La ingesta se evaluó a partir de un cuestionario de frecuencia de consumo y un registro de alimentos de 3 días. La adherencia a la DM se estimó con el Mediterranean Diet Score. Las diferencias entre las variables en función del sexo y la práctica deportiva se analizaron con la t de Student o la U-Mann-Whitney. Signifi cación estadística: p < 0,05. Resultados: todos los sujetos presentaron normopeso, sin diferencias en función de la práctica deportiva. El nivel de actividad física fue inferior en las mujeres. En todos los estudiantes la dieta fue ligeramente hiperproteica, rica en grasas y colesterol, con un inadecuado perfi l lipídico y defi ciente en hidratos de carbono y fi bra. Se cubren los r...

Body composition (BC) determines strength, power, and agility in sports such as rugby. Not only is the study of morphology and BC essential to establish player positions, but it also allows the optimisation of competitive performance. The aim of this study was to analyse different BC models (anthropometry and bioelectrical impedance analysis (BIA)) in a female rugby team. Their somatotype was also compared with a bioelectrical impedance vector analysis (BIVA) graph. A cross-sectional study was carried out on 19 women (8 forwards and 11 backs). Anthropometric and BIA (50 kHz, tetrapolar electrode configuration) measurements were taken using standard protocols and BC was estimated. Somatotype was calculated using the Heath–Carter method. Classic and specific BIVA were applied. Student’s t, Mann–Whitney, or Chi-squared tests were used for variable comparisons. Agreement was determined via intraclass coefficient correlations. Forwards showed a higher BMI and fat mass, but there were no differences in skeletal muscle masses. Most of the players were of an endomorphic mesomorph somatotype. Specific BIVA, but not classic BIVA, detected BC differences according to player position. Moreover, an individual’s interpretation of BIVA was consistent with their somatotype. In a female rugby team, BC and morphology are different according to position. This was detected in both the somatotype and specific BIVA. The application of BIVA (classic and specific) may yet prove to be a very useful strategy for the study of BC in sports.
