Introduction Since its debut at the 1996 Atlanta Olympics, beach volleyball has grown on the international sports scene. An extensive collection of data from several countries and levels of competition will provide a database that can be used to characterize beach volleyball players and define references for training stages. Objective The purpose of this study was to describe and compare the anthropometric profiles of Spanish male and female beach volleyball players at different levels of competition in relation to sports performance. Methods The sample comprised 150 players participating in the 2011 Spanish Beach Volleyball Championships (Under 19, Under 21, and Senior categories). Using the ranking provided by the Royal Spanish Volleyball Federation, the subjects were distributed by performance level (level 1: players ranked first to fourth; level 2: players ranked fifth to ninth; and level 3: players ranked tenth to seventeenth). The study comprised a group of male players, with 18 level 1 ( M1 ), 39 level 2 ( M2 ), and 22 level 3 players ( M3 ), and a group of female players, with 18 level 1 ( F1 ), 41 level 2 ( F2 ), and 12 level 3 players ( F3 ). Results The top level male sample ( M1 ) had a significantly lower average age (19.33 years) than the men’s international elite players (30 years). The top Spanish players of both genders had much lower values for height and body weight than the international elite players. Conclusions Height and fat component are responsible for the differences between top and lower level beach volleyball players, for both men and women. Moreover, as the level of performance increases, players are taller and have a lower fat component. In view of the data observed in this study, the talent selection process in Spanish beach volleyball should aim to select taller individuals than at present.

La interpretación en lengua de signos demanda una gran competencia cognitiva y física en el intérprete de lengua de signos (ILS). Nuestro interés es estudiar, a través de la metodología de recogida de datos del análisis crítico del discurso, cómo preparan los ILSs sus contextos discursivos, incluyendo el esfuerzo físico existente. Realizamos un estudio mixto: cualitativo, del contexto discursivo y cuantitativo, evaluando la musculatura implicada, obteniendo como resultado que es de vital importancia que el ILS tenga la información con antelación para poder adaptarse rápidamente a diferentes ritmos del discurso y la tensión que las situaciones generan. Ya que deben enfrentarse a una amplia variedad de desafíos relacionados con las tareas, cognitivos y físicos, favoreciendo el posible riesgo de lesión muscular, es necesario para el ILS realizar actividades físicas compensatorias y preventivas. El conocimiento previo sobre el contenido a interpretar, los usuarios, características del lugar y otros aspectos a tener en cuenta, según el servicio, proporciona mejores herramientas para la realización del trabajo.
