ABSTRACT

El objetivo de este estudio fue analizar la secuencia de los dos últimos golpeos del punto en pádel, y clasificarlos a través de árbol decisional multivariante. Se analizaron un total de 2110 acciones de juego, siendo las variables analizadas: golpeo, zona de la pista, eficacia, dirección, resultado y lado de juego. Los partidos fueron analizados mediante observación sistemática. Los resultados mostraron que mantener posiciones cercanas a la red aumenta las probabilidades de victoria, observándose que las secuencias de finalización más frecuentes son las de fondo-volea y globo-remate. Las parejas ganadoras realizan mayor número de puntos ganadores en la red y menos errores en el fondo de la pista. Además, utilizar trayectorias cruzadas en el penúltimo golpe aumentará las posibilidades de un error posterior de los rivales. Estos datos tienen aplicación práctica en el entrenamiento perceptivo y decisional del jugador de pádel, y la aplicación de feedbacks por parte del entrenador. (AU)


The main objective was to analyze the sequence of the last two shots of the point in padel and to make a classification through the multivariate decision tree approach. A total of 2110 game actions were analyzed. The variables analyzed were: shot, court zone, efficiency, direction, match outcome and side court. Matches were analyzed through systematic observation. The results determined that maintain net positions during the last two shots would increase the probabilities of victory, observing that the most frequent sequence of the last two shots were groundstroke-volley and lob-smash. In addition, winners make the highest number of winning points on the net and the least number of errors at the baseline. On the other hand, the use of cross-court shots will increase the chances of a opponents’ error. These data have an important practical application in the perceptive and decisional training and the feedback application by the coach. (AU)

ABSTRACT

A pesar de que el saque es el golpe más determinante en el tenis moderno, existen hasta la fecha pocas investigaciones en tenis profesional femenino. El objetivo del presente estudio fue identificar las diferencias en la dirección y eficacia del saque en función del ranking; así como observar las diferencias según la lateralidad de la jugadora rival (diestra o zurda) en torneos de Grand Slam. Se analizaron un total de 108 partidos femeninos disputados en los torneos del Abierto de los Estados Unidos y Wimbledon. Los resultados mostraron una mayor variabilidad en la táctica del saque en Wimbledon frente al Abierto de Estados Unidos. Además, se identificaron diferencias en la dirección y eficacia del saque de las jugadoras diestras en función de la lateralidad del rival, en especial cuando se sacó a jugadoras zurdas. Estos resultados contribuyen al conocimiento de las dinámicas y rendimiento del saque en las jugadoras de tenis profesionales. (AU)


Serve is the most important stroke in modern tennis, but the number of studies on professional women’s tennis is scarce. The aim of the present study was to identify differences in service direction and effectiveness regarding players’ ranking position; as well as to observe the differences according to the opponent’s laterality (right-handed or left-handed). A total of 108 matches from the US Open and Wimbledon tournaments were analysed. Results showed a larger variability in service tactics in Wimbledon compared to the US Open. In addition, the direction and effectiveness of the service of right-handed players differed depending on the opponent’s laterality, especially against left-handed players. These results contribute to the knowledge of the service dynamics and performance in professional women’s tennis players. (AU)

ABSTRACT

El objetivo de este estudio fue analizar las demandas físicas de la competición en pádel de iniciación, y observar la influencia de diferentes tipos de pelota Dieciséis jugadores de pádel en iniciación participaron en este estudio. Cada judador portó un pulsómetro durante el partido. Se utilizaron cuestionarios al término de cada partido para evaluar el esfuerzo percibido y la satisfacción. Los resultados no mostraron diferencias significativas en la estructura temporal de los partidos. Se encontraron diferencias (p < 0,001) entre los partidos con pelota normal y pelota de baja presión tanto en la frecuencia cardiaca media (145,43 ppm vs 140,19 ppm) como en el %FCmáx (72,47 vs 69,85). Los jugadores mostraron mayor satisfacción en el uso de pelotas de baja presión. Estos datos pueden ser de utilidad para determinar el uso de un tipo de pelota u otra y mejorar la planificación del entrenamiento específico en jóvenes jugadores de pádel


The aim of this study was to analyze the physical demands in padel initiation stage and to observe the influence of playing with different type of padel balls. Sixteen padel players at initiation stage participated in this study. Players wore a heart rate (HR) monitor. Perceived exertion and satisfaction questionnaires were administrated at the end of the matches. No differences were found in the match temporal structure. Playing with official balls caused a significant increase in HR (p < 0.001) both in average and maximal values (Average HR: 145 bpm, %HRmax: 72.5%) comparing to low-compression balls (Average HR: 140 bpm, %HRmax: 69.9%). In addition, players showed higher satisfaction when using low-compression balls. This information may have implications to determine the use of normal balls or low-compression balls and the design of specific training programmes for young padel players

ABSTRACT

El objetivo del presente estudio es conocer los efectos en la cantidad y eficacia de golpeos y la percepción de satisfacción/diversión, aburrimiento y esfuerzo a través de cuatro formas de organización diferentes de sesiones de pádel. Los participantes del estudio fueron 48 estudiantes del Ciclo Formativo de Técnico en Animación y Actividades Físico Deportivas (33 chicos y 15 chicas), con edades comprendidas entre los 18 y los 26 años. Se evaluó la cantidad y eficacia de los golpeos a través de una hoja de observación directa. La percepción de diversión y aburrimiento fue evaluada a través del Sport Satisfaction Instrument y la percepción de esfuerzo a través de la Pictorial Children's Effort Rating Table. Los resultados obtenidos muestran que la forma de organización basada en el peloteo entre los alumnos se plantea como la más eficaz en la enseñanza del pádel, obteniendo un número significativamente mayor y más eficaz de golpeos, así como valores significativamente superiores de diversión/satisfacción y esfuerzo e inferiores de aburrimiento (AU)


The aim of this study was to determine the effects on the quantity and effectiveness of strokes and perceived satisfaction / fun, boredom and effort through four different organizational forms of paddle sessions. Study participants were 48 students from the Technical Training Course in Animation and Sports Physical Activities (33 boys and 15 girls) with ages between 18 and 26 years. The amount and effectiveness of beatings through direct observation of a sheet was evaluated. The perception of fun and boredom was evaluated through the Sport Satisfaction Instrument and perception of effort through the Pictorial Children's Effort Rating Table. The results show that the form of organization based on the rally among students is seen as the most effective in teaching paddle. A significantly greater and more effective number of strokes and significantly higher values ​​of amusement / satisfaction and effort and lower boredom have been proved as a result of this form of organization (AU)

ABSTRACT

STUDY DESIGN: There is a lack of information about the physiological and psychological parameters in competition that shows a comprehensive profile of the demands of the game situation. OBJECTIVE: The aim of the present study was to examine the activity patterns and physiological-perceptual responses (heart rate (HR), blood lactate concentrations (LA) and the rate of perceived exertion (RPE), respectively, during singles wheelchair tennis (WT) matches. METHODS: A total of four WT players played three matches each. HR, LA and RPE were measured during each match. An activity pattern analysis was performed during all matches. Furthermore, LA and RPE were compared between service and return games. RESULTS: The results show a mean (s.d.) total match time of 69.04 (2.3) minutes, an effective playing time of 17.65% (0.03%), a work:rest (W:R) time ratio of 1:4.6 (0.48) and a rally length of 7.04 (4.44) seconds. Most of the points end in three or fewer shots. The mean (s.d.) physiological load during the matches were as follows: HR 124.25 (24.7) beats per minute, %HRmax 66.31% (4.5%), LA 1.41 (0.43) mmol l(-)(1) and RPE 12.45 (1.91). No significant differences were found in LA and RPE between service and return games (P>0.05). CONCLUSIONS: In this descriptive study, match activity and physiological load in WT are described. Match activities are similar to conventional tennis, although the physiological load is lower. Service and return situations show similar physiological and perceptual responses. These results might be used to develop specific interval training protocols for a male WT player.
