Video Sequence Analysis for On-Table Tennis Player Ranking and Analysis

With the rapidly developing of the scientific research in the field of sports, big data analytics and information science are used to carry out technical and tactical statistical analysis of competition or training videos. The table tennis is a skill oriented sport. The technique and tactics in table tennis are the core factors to win the game. With the endlessly emerging innovative playing techniques and tactics, the players have their own competition styles. According to the competition events among athletes, the athletes’ competition relationship network is constructed and the players’ ranking is established. The ranking can be used to help table tennis players improve daily training and understand their ability. In this paper, the table tennis players’ ranking is established their competition videos and their prestige scores in the table tennis players’ competition relationship network.

Investigating the role of age and maturation on the association between tennis experience and cognitive function in junior beginner to intermediate-level tennis players

Sport engagement, including tennis, and physical activity have been shown to have a positive influence on cognition in children. However, age has also been found to have a strong association with cognition in youth athletes. This study examines the threshold hypothesis by investigating the moderating role of age and maturation on the association between tennis experience and cognitive measures in Australian and German junior beginner to intermediate-level tennis players. The demographic information, which includes years of tennis experience, and anthropometrics (e.g. height and weight) was collected for 48 junior tennis players. A comprehensive cognitive testing battery was then completed to assess cognitive performance, with a principle component analysis used to determine an overall cognitive performance score. Multiple regression analyses were then performed to test the relationship between tennis experience and cognitive performance as well as the moderating effects of age and maturation. The results of this study indicate that the age and maturation rather than the exposure to tennis training are related to cognitive performance. Additionally, the positive relations of tennis experience to cognitive performance were stronger in younger participants, specifically those younger than 12 years old. Therefore, tennis may not provide a stimulus large enough for further cognitive improvement once players have developed a high level of cognitive performance. While age and biological maturity will largely dictate cognitive performance in adolescents, tennis experience may play some role in the cognitive performance of children (specifically <12 years of age).

Building foundations for the future: A case study with LTA Youth

This article discusses modern challenges experienced when developing tennis players including low levels of physical literacy. It then outlines the needs of a young child and learning strategies that can be used. A brief overview of some practical strategies for engaging early years participants, using a player-centred approach, are shared using examples from LTA Youth with explanations of how each exercise integrates key principles to attract and retain early years participants.

The relationship of some physical variables and performance angles to the strength of the straight serve for junior tennis

The problem of the research in determining the appropriate angles in the strength of serve for tennis age (14-16) year according to the specific biomechanical conditions, and the extent of the relationship of each variable of the physical variables in the successful performance of the skill of serve, and achieving the strength of transmission for tennis age (14-16) year, and it is one of the biomechanical principles that can be used in evaluating the angles of body parts. age (14-16) year tennis players. The aim of the research is to identify the percentage of the contribution of some physical variables of the straight serve for tennis juniors, and the percentage of the contribution of some corners of the body to the strength of serve for the tennis age (14-16) year (18) players. The two researchers reached a number of results, the most important of which are: There is a statistically significant correlation between some physical abilities and body angles with the straight serve for tennis players. The lower the angles (elbow, shoulder, knee for the front leg) at the moment of hitting the tennis ball, the stronger the serve will be. Correlation relationship with some biomechanical variables, because the skill of serve requires the strength of the striking arm during the performance of the straight serve

Emotions in young tennis players: a new tennis-specific scale

To understand and assess responses related to the inadequate management of emotions in tennis competition, it has been developed the “Scale Perception Emotion Tennis” (SPET). This article will describe how the SPET tool could represent a first step in the direction of increasing awareness of the players and could be used by the coaches to compare their perception of the player’s emotions with the one of their athletes.

Effect of practice hours on elite junior tennis players’ burnout: Gender differences

This study investigated the effect of training hours on elite junior tennis players’ burnout with attention to gender differences. A quantitative cross-sectional design was used in this research. A sample of 70 junior elite Tunisian tennis players (17.01 ± 0.81y) completed a demographic and the Athlete Burnout Questionnaire. Results showed that 64% ( n = 45) had a low risk, 14% ( n = 10) had a moderate risk, 13% ( n = 9) showed a high risk of burnout and 9% ( n = 6) had burnout with individual differences. Analysis of variance revealed that players who trained more than 12 h (high volume) reported significantly higher scores of the burnout dimensions: emotional and physical exhaustion ( p < 0.001; d = 2.18); sport devaluation ( p < 0.001; d = 2.36); reduced sense of accomplishment ( p < 0.001; d = 2.27); as well general burnout ( p < 0.01; d = 2.69), than players that trained less than 12 h (moderate volume and low volume). The effect of gender was observed in the variables of emotional and physical exhaustion (t = 2.17; p < 0.03), sport devaluation ( t = 2.23; p < 0.029), reduced sense of accomplishment ( t = 2.58; p < 0.012) and general burnout ( t = 2.41; p < 0.019) with female players showing higher scores in all of the burnout dimensions. It was concluded that the high volume of weekly training hours by junior players was associated with higher levels of the general burnout scores and that female players showed higher burnout scores than their male counterparts.

Carga interna y externa en el tenis de competición: comparación de tres tipos de entrenamiento (Internal and external load in competitive tennis: comparison of three types of training)

El objetivo principal de esta investigación es cuantificar la carga externa y la carga interna en tres tipos de entrenamiento (cubos con la mano, cubos con raqueta y peloteos) más utilizados en el ámbito del tenis de competición y compararlos entre sí. Participaron 6 jugadores de tenis (cuatro jugadores masculinos y 2 jugadoras) con una media de edad de 16.67 (± 2.73) años. Para cuantificar las cargas, se han utilizado pulsómetros POLAR +M400 para recoger los datos relacionados con la frecuencia cardíaca, distancia recorrida, velocidad media y máxima, y sensores ZEPP TENNIS, con los que se han recogido los datos relativos a tipo de golpe, número de golpeos y velocidad de raqueta en cada uno de los golpes realizados. Además, para registrar la percepción subjetiva de esfuerzo, en cada tarea realizada y al final de cada entrenamiento, se ha utilizado la Escala de Borg CR-10 (Borg, 1982). Se realizaron 9 sesiones de entrenamiento por parejas: tres para el entrenamiento del drive, tres para el entrenamiento del revés y tres para el entrenamiento del drive y el revés de forma conjunta, una para cada tipo de entrenamiento. Los resultados obtenidos muestran que el entrenamiento de cubos con la mano tiene mayor carga interna en cuanto a número de golpeos y velocidad media de raqueta, siendo el entrenamiento de peloteos el que mayor carga externa refleja en relación a velocidades y distancias recorridas. Abstract. The main objective of this research is to quantify the external load and the internal load in three types of training (buckets with the hand, buckets with racket and rallies) most used in the field of tennis and compare them to each other. Six tennis players participated (four male and two female players) with an average age of 16.67 (± 2.73) years. To quantify the loads, POLAR +M400 heart rate monitors were used to collect the data related to heart rate, distance covered, average and maximum speed, and ZEPP TENNIS sensors were used to collect the data related to type of stroke, number of strokes and racket speed for each of the strokes made. In addition, the Borg CR-10 Scale (Borg, 1982) has been used to record the rate of perceived exertion, in each task performed and at the end of each training session. Nine training sessions were carried out in pairs: three for drive training, three for backhand training and three for drive and backhand training together, one for each type of training. The results obtained show that bucket training with the hand has a greater internal load in terms of the number of strokes and average racket speed, with racket training having the greatest external load in relation to speed and distance travelled.
