Abstract
<p class="resumenyabstract">The purpose of this work is to study the goalkeeper behavior and movement precue during the approaching race of the shooter to the ball, and compare professional (1&ordf; y 2&ordf; Division) and amateur (3&ordf; Division) precue movement. Six professional goalkeepers (29.66+3.5 age) and 6 amateur goalkeepers (23.16+3.7 age) part in this study. The goalkeepers movement were filmed during 40 shoots, 20 from right shooter and 20 from left shooter, with a digital video camara. We applied a descriptive sectional design to analysed the subjets, and comparative sectional design to compared professional and amaterus goalkeepers. We identify two precues movementen to the left or right, by means of cinematic techniques applied: A knee extensi&oacute;n higher than 150&ordm; determine a movements towards the other part of the body. A knee flexion higher than 100&ordm; determine a movement toward this part of the body. No exist significant differences among profesional and amateurs goalkeepers <br />KEY WORDS: precues, penalty, soccer, training, motor control and learning</p>

Para este estudio se han seleccionado 6 porteros profesionales (29.66+3.5 a&ntilde;os) y 6 porteros amateur (23.16+3.7 a&ntilde;os), a los cuales se le han filmado con una video c&aacute;mara durante 20 lanzamientos, 10 lanzamientos realizados por un jugador zurdo y 10 lanzamientos por parte de un lanzador diestro. Hemos utilizado un dise&ntilde;o seccional descriptivo para el an&aacute;lisis de todos los porteros y un dise&ntilde;o seccional comparativo para establecer diferencias entre porteros profesionales y amateur. Mediante la aplicaci&oacute;n de t&eacute;cnicas de an&aacute;lisis cinem&aacute;tico bidimensional de las im&aacute;genes filmadas, hemos podido identificar las trayectorias de diferentes partes del cuerpo antes del golpeo del bal&oacute;n. Se han obtenido dos variables significativas que nos permiten predecir el movimiento final del portero hacia derecha o hacia izquierda antes del golpeo del bal&oacute;n: un &aacute;ngulo de extensi&oacute;n de la rodilla superior a 150&ordm;, lo cual determinar&iacute;a un desplazamiento del portero hacia el lado contrario al de esta rodilla y un &aacute;ngulo de flexi&oacute;n de la rodilla inferior a 100&ordm; , lo cual determinar&iacute;a un desplazamiento del portero hacia el lado coincidente con dicha rodilla. No se han encontrado diferencias significativas entre porteros profesionales y amateur en cuanto a los patrones de movimento de anticipaci&oacute;n al golpeo del bal&oacute;n.<br />PALABRAS CLAVE: preindices, penalti, f&uacute;tbol, entrenamiento, control y aprendizaje motor</p>
