El objetivo de este estudio es comprobar si el estilo de natacion en el que estan especializados los nadadores, influye sobre la extensibilidad isquiosural de los deportistas que han participado en esta investigacion. El test empleado para este trabajo es el test “sit and reach”. Se ha medido la extensibilidad isquiosural de todos los nadadores (N=36) de ambos sexos, que entrenan en un centro de tecnificacion acuatico espanol. La edad de los participantes del estudio oscila entre los 13 y los 17 anos. Esta poblacion de nadadores ha sido dividida en cuatro grupos diferentes, dependiendo del estilo de natacion en el que estan especializados (crol, espalda, braza y mariposa). Para conocer la influencia del estilo natacion sobre los resultados obtenidos en el test “sit and reach”, se ha aplicado un test inicial y nueve meses mas tarde un test final, lo que ha permitido conocer tambien la evolucion de las mediciones. Como conclusion, la extensibilidad isquiosural y su evolucion, no esta condicionada por el estilo de natacion en el que estan especializados los nadadores que han participado en este estudio. PALABRAS CLAVE: Natacion, sit and reach, extensibilidad isquiosural, flexibilidad, dolor de espalda, estilos de natacion, mariposa, braza, espalda, crol. ABSTRACT The aim of this research is to verify the swimming style in which swimmers are specialized, have has influences hamstring extensibility athletes who have had participated in this research. The employed test for this work was the “sits and reach" test. It was measured hamstring extensibility of all swimmers (N = 36) of both sexes, who train in Spanish aquatic center modernization. The age of the study participants is between 13 and 17 years. This population of swimmers has been divided into four different groups, depending on the style of swimming in which they are specialized (crawl, backstroke, breaststroke and butterfly). To determine the influence of swimming style on the results obtained in the test "sit and reach", it having had applied an initial test before, and a final test nine months later, which have had permitted also know the measurements evolution. In conclusion, the hamstring muscle extensibility and its evolution have had being not conditioned by swimming style of the swimmers. KEYWORDS: Swimming, sit and reach, hamstring extensibility, flexibility, backache, swimming strokes, butterfly, breaststroke, backstroke, front crawl.
