RESUMO

Aims: The aim of the present study was to analyze the differences in wheelchair tennis game statistics between winning and losing sets. Methods: Data were collected from the 139 sets of 64 matches played by 64 males' players in the 2012 Paralympics Games. The variables studied were grouped in four groups: variables related to serve, to return, to winners and errors, and to net point. Data was collected from official website of the Paralympics Games. A univariate (Wilcoxon test) and multivariate (discriminant) analysis of data was done to the study the four groups of variable in relation to the result of the set (win or lose). Results: The result showed that winning players commit fewer errors and achieved more winning shots than losing players. Conclusion: The values presented could be used as a reference for practice and competition in wheelchair tennis players.(AU)

RESUMO

El objetivo de este estudio fue analizar la influencia del incremento de la carga de entrenamiento por medio del método Repeated Sprint Ability (RSA) sobre el estado de ánimo de jóvenes tenistas. Participaron 30 tenistas (15.78± 1.58 años) en este programa de entrenamiento (7 semanas). Los sujetos fueron divididos en tres grupos: G1, volumen de entrenamiento de tenis más un incremento del 8.3% por medio de RSA; G2, ídem más un incremento de 16.6% de RSA; y G3, entrenamiento de tenis. El entrenamiento específico de tenis fue controlado e igualado, además se cumplimentó un cuestionario semanal para establecer el perfil de estado de ánimo (Balaguer, Fuentes, Meliá, García-Mérita & Pons, 1995). Los resultados mostraron variaciones en G1 y G2. Mientras en G1 las puntuaciones de los factores tensión y fatiga se incrementaron al final del programa (p < .05), en G2 aumentaron las puntuaciones de tensión, depresión, hostilidad y fatiga al comienzo del programa, y se redujeron significativamente al final (p < .05). En G3 no hubo modificaciones. La diferente evolución del estado de ánimo de los sujetos en función del volumen de entrenamiento de RSA realizado, muestra la necesidad de monitorizar la carga interna para ajustar este entrenamiento.


The aim of this study was to analyse the influence of the repeated sprint ability (RSA) training load increase on the mood states in young tennis players. Thirty tennis players (15.78 ±1.58 years) took part in this training program (7 weeks). The subjects were divided into 3 groups: G1, specific tennis training and an increase of 8.3% of RSA training volume; G2 specific tennis training and an increase of 16.6% of RSA training volume; G3, only specific tennis training. The specific tennis training volume was controlled and equated for this period, and all the subjects also filled out a weekly questionnaire to establish the profile of mood states (POMS, Balaguer, Fuentes, Meliá, García-Mérita & Pons, 1995). The results showed changes in G1 and G2. Whereas tension and fatigue scores increased at the end of the training program in G1 (p < .05), scores of tension, depression, hostility and fatigue were higher at the beginning than at the end of the training program in G2 (p < .05). There were no significant changes in G3 for any variable. The different evolution of subjects' mood states based on RSA training volume performed shows the need for monitoring internal load to fit this training.

RESUMO

La literatura científica ha demostrado a través de diversos métodos (cuestionarios y acelerómetros, principalmente) que las clases de educación física (EF) influyen positivamente en el logro de las recomendaciones de actividad física (AF) en la población escolar. Sin embargo, el uso de nuevas tecnologías como los teléfonos móviles o smartphone, parecen ser una interesante herramienta de bajo costo que también podrían ayudar a determinar el nivel de AF. Por tanto, el objetivo del presente estudio fue describir como influye la clase de EF en el número de pasos diarios en escolares que utilizaron una aplicación móvil “RuntasticPedometer” para monitorear dicha variable. La muestra estuvo compuesta por 50 estudiantes (edad media de 14.1 +/-1.6 años) pertenecientes al Instituto de Educación Secundaria “Melchor de Macanaz” de la localidad de Hellín (Albacete, España). Tras analizar los datos, se observaron diferencias significativas (p<0.05) durante los días en que los escolares realizaron la clase de EF y los que no (9.950 vs. 8.023 pasos/día,respectivamente). Además, la variación entre los días con y sin EF también fueron estadísticamente diferentes entre niños y niñas (2.644 vs. 1.579 pasos/día, respetivamente).Finalmente, se podría concluir que las clases de EF parecen influir positivamente en el aumento del número de pasos en escolares, lo que elevaría las posibilidades de que estos niños y niñas logren los parámetros mínimos de AF recomendada por las diversas organizaciones de salud. Por otro lado, cabe señalar que el uso de nuevas tecnologías de uso masivo como los smartphone, podrían ser una interesante herramienta a validar orientadas al monitoreo de la AF.


The scientific literature has demonstrated through various methods (questionnaires and accelerometers, mainly), the classes of physical education (PE) positively influence the achievement of the recommendations of physical activity (PA) in the school population. However, the use of new technologies such as mobile phones or smartphone, appear to be an interesting inexpensive tool that could also help determine the level of AF. Therefore, the objective of this study was to describe as PE class influences in the daily number of steps in school who used a mobile application "Runtastic Pedometer" to monitor the variable. The sample consisted of 50 students (mean age 14.1 +/- 1.6 years) belonging to the Institute of Secondary Education "MelchorMacanaz" from the Hellín (Albacete, Spain). After analyzing the data, significant differences (p <0.05) were observed during the days when the school made PE class and those without (8,023 vs. 9,950 steps / day, respectively). Moreover, the variations between days with and without EF were also statistically different between boys and girls (2,644 vs. 1,579 steps/day,respectively). Finally, one could conclude that PE classes seem positively influence the increase in the number of steps in school raising the chances that these children achieve the minimum standards recommended HF various health organizations. On the other hand, it notes that the use of new technologies in widespread use as the smartphone could be an interesting tool to validate oriented monitoring AF.
