This study addresses the visual and motor behavior, and success rate, of 40 novice tennis players in a laboratory setting and an on-court situation when viewing a passing-shots rally performed by an expert tennis player located at the back line of the court. The tennis players had to move fast and quickly through forehand or backhand volleys. Visual search strategies were recorded with an ASL SE5000 eye tracking system, and a computerized system was used to analyze the time parameters of the motor response. The dependent variables are the time of visual fixation on the corporal or spatial locations, reaction and movement times, response time (or the sum of the two variables), and success rate of the responses. The results show that the sample of novice players were faster in 2D and fixed more time on the central area of the opponent body (e.g., trunk, hip). Thus, novice players fixed more on the upper body of the opponent (e.g., head, shoulders) in 3D. Therefore, tennis players develop a differentiated visual and motor behavior according to the way they perceive the opponent's movement, whether in a video projection or on the tennis court. It is recommended to carry out representative tasks in the laboratory to provide perceptive and motor processes similar to real situations. (C) 2015, Konrad Lorenz University Foundation.

El estudio compara el comportamiento visual y motor de 40 tenistas noveles en laboratorio (2D) y en pista de tenis (3D) cuando visualizan una secuencia de passing-shots ejecutada por un oponente experto desde el fondo de la pista. Los tenistas deben responder rápida y precisamente mediante un armado de volea de derecha o de revés según la dirección del golpeo. Para el registro del comportamiento visual, se utiliza el sistema tecnológico ASL SE 5000, mientras que para el comportamiento motor, se adapta un sistema tecnológico para el entrenamiento de las habilidades motoras abiertas. Las variables dependientes son: el tiempo de fijación visual en cada localización corporal o espacial; el tiempo de reacción y de movimiento, tiempo de respuesta (o suma de las dos variables anteriores), y eficacia de la respuesta. Los resultados evidencian que la muestra de tenistas noveles se fija más en la zona central del cuerpo del oponente (tronco, cadera) y son más rápidos en 2D. En cambio, en 3D se fijan más en la zona superior del oponente (cabeza, hombros). Por lo tanto, los tenistas desarrollan un comportamiento visual y motor diferenciado según perciban el movimiento del oponente de forma videoproyectada o en pista de tenis. Se recomienda diseñar tareas representativas en laboratorio que ofrezcan a los deportistas procesos de percepción y de acción similares a situaciones reales de competición.

El treball d’investigacio analitza, des d’una perspectiva cognitiva, el comportament visual i motor d’una mostra de tennistes novells durant la percepcio de diversos moviments de cop fets per un tennista oponent. Es registren les fixacions visuals (temps i localitzacio) a traves del sistema de seguiment de la mirada ASL SE5000, els parametres temporals de la resposta motriu (temps de reaccio, temps de moviment i resposta de reaccio) i la seva eficacia a traves d’un sistema tecnologic creat per a aquest efecte. Els resultats mostren que els tennistes fixen mes la seva visio en el membre superior (cap, espatlles i tronc) per als cops de dreta, mentre que la fixen mes en el membre executor (brac executor i ma-raqueta) i bola per als cops de reves. A mes a mes, els tennistes reaccionen i responen abans davant de cops de dreta que de reves, i davant de cops paral·lels que encreuats. No hi ha diferencies en l’eficacia de la resposta segons el tipus o direccio del cop. Es recoman a a entrenadores de tennis ensenyar una estrategia de recerca visual d’indexs de moviment segons el tipus i direccio del cop, especialment per als cops de reves i encreuats, ja que dificulten que es reaccioni i respongui abans.

Twenty participants were tested on rapid elbow extension movements. This experiment examined the effects of the type of termination (pointing vs. impact movements) and sport practice (karate vs. volleyball) on temporary specific electromyographic (EMG) and kinematic measures during elbow extension movements. EMG was recorded from triceps (main agonist) and biceps (main antagonist). The analysis of variance on the type of movement showed differences on the time from onset of EMG activation to peak EMG in agonist and antagonist when these variables are normalized to a proportion of total movement time. Also, correlation analysis showed strong correlations between the kinematic variables and the time from onset of EMG antagonist to peak EMG. This variable is the only EMG variable that presented differences in the analysis between sport groups. The results allow us to conclude that the delay in the biceps action expressed in the time from onset EMG activation to peak EMG normalized to a proportion of total movement time is an indicator of the performance level in fast movements.

... En el tenis, son varios los estudios que han abordado esta temática, analizando aspectos como el comportamiento visual y motor, el trabajo de pre-índices, la anticipación, el tiempo y respuesta de reacción y el trabajo de oclusión y de fijación (Farrell, 1996;Crespo, 1997;Avilés et al., 2002;Del Campo et al., 2008;Del Campo et al., 2012;Del Campo et al., 2015). Williams et al. (2013) observaron que tanto un entrenamiento centrado únicamente en la habilidad perceptiva como un entrenamiento perceptivo-ejecutivo producían mejoras en la habilidad perceptiva y en la anticipación en tenistas iniciantes e intermedios. ...

... The key to this is to design a suitable transfer test for the training task (Lorains et al., 2013;Larkin et al., 2015). This is an important consideration in the study of perceptualcognitive skills because athletes are ultimately measured by their performance on the court (Luis del Campo et al., 2015). Only one of the included studies included the transfer test to evaluate the likelihood of transferring training effects to real matches (Gabbett et al., 2008). ...
