Introduction Each June, Wimbledon Centre Court becomes the focal point for the performances of the world’s leading tennis players. Matches showcase pure theatre—the drama, the sweat, the joy and tears, not to mention the physique of the players and the contortions of their bodies as they move around the court. In 2011, Bethanie Mattek-Sands arrived on court at Wimbledon in a costume designed by...

Tennis-sports analysis is attracting much attention in content-analysis research and professional applications. This paper presents a scheme for sports analysis employing an automatic tennis ball-path inference driven by a combination of auditory and visual information. The ball-path inference is implemented for tactics analysis. Since ball tracking remains to be a challenging issue in practice...

This study evaluated the effectiveness of a tennis-specific training program on improving neuromuscular indices in competitive junior players. Tennis is a demanding sport because it requires speed, agility, explosive power, and aerobic conditioning along with the ability to react and anticipate quickly, and there are limited studies that evaluate these indices in young players after a multiweek...

In tennis, the relative positioning of players on court constrains their opportunities to perform successful actions. In this study we proposed and validated an empirical function that captures the spatial-temporal relationship between tennis players during competitive performance. This parameter, termed goal-directed displacement index (GDD Index), is defined over time by the product of both p...

This study analysed how the relative positioning of players on court influenced patterns of interpersonal coordination in baseline rallies in tennis. We developed a model (PA index) that assigns a weight to the position of each player on court and determines a positional advantage, based on the relative proportionality between the lateral and longitudinal displacement values during rallies. To ...

The range of a power wheelchair depends on many factors including: battery type, battery state, wheelchair/rider weight, terrain, the efficiency of the drive train, and driving behavior. The purpose of this study was to evaluate the feasibility of three methods of estimating power wheelchair range. Another significant purpose was to compare the current draw on pavement to current draw on an Int...

In Europe, tennis courts are often built near houses. Therefore, in Europe, tennis together with soccer belongs to the most important sports for an investigation of recreation noise evaluation [1]. The residents near such sport grounds bemoan most of all the impulseand information-contents of these noises. Tennis-shots with the racket and the ball contacts with the ground cause the high impulse...

AIM: During tennis, the development of fatigue has been shown to induce performance decrements. However, it is not known specifically if the forearm muscles play a key factor in skilled performance. The aim of the current study was to investigate forearm fatigue following a tennis protocol and to determine the physiological and performance effects of a novel tennis grip on forearm muscle fatigu...

This paper addresses the implementation of an advanced visual-based tennis sports video analysis system. Firstly, a white pixel-fraction based method is used to detect the significant frames that include the tennis court. In addition, we employ the temporal correlation between two consecutive frames to track the court location within a local search area. Furthermore, we propose a player segment...

a r t i c l e i n f o Fully automatic annotation of tennis game using broadcast video is a task with a great potential but with enormous challenges. In this paper we describe our approach to this task, which integrates computer vision, machine listening, and machine learning. At the low level processing, we improve upon our previously proposed state-of-the-art tennis ball tracking algorithm and...
