Rhythm training is an integral part of sports. The purposes of the study were to analyze the effects of rhythm training on tennis performance and rhytmic competence of tennis players, to compare the improvement levels of tennis specific and general rhythm training and to examine the effects of shorter and longer tempos on rhythmic competence. Thirty university students whose mean score of Inter...

We apply domain adaptation to the problem of recognizing common actions between differing court-game sport videos (in particular tennis and badminton games). Actions are characterized in terms of HOG3D features extracted at the bounding box of each detected player, and thus have large intrinsic dimensionality. The techniques evaluated here for domain adaptation are based on estimating linear tr...

In sports analysis, player trajectory and occupancy map are widely used for visualizing interesting objects (players and balls). Lines are overlaid on the court to visualize the trajectory of players. For example, Fig. 1 (a) shows the trajectory of team centroid. Also, the derived game phases (e.g. offensive play, defensive play and time out) from the trajectory are visualized by ellipses (Fig....

Space or voxel carving is a non-invasive technique that is used to produce a 3D volume and can be used in particular for the reconstruction of a 3D human model from images captured from a set of cameras placed around the subject. In [1], the authors present a technique to quantitatively evaluate spatially carved volumetric representations of humans using a synthetic dataset of typical sports mo...

VISION SYSTEM, produced by Newton Research Labs. The authors embedded the vision system in a small robot base to tie for first place in the Clean Up the Tennis Court event at the 1996 Annual AAAI Mobile Robot Competition and Exhibition, held as part of the Thirteenth National Conference on Artificial Intelligence. Of particular interest is that the authors’ entry was the only robot capable of u...

In tournaments in various sports that feature one-on-one competition, the trophy is sometimes prominently displayed near the athletes during the final. Based on recent research on subtle reward cues, we propose that such trophies have the potential to induce choking under pressure in the match favourites, who are known to be most at risk. To test this idea, we analysed real-life tennis performa...

Ann Saudi Med 2006;26(5):343-345 The vascular endothelium is the largest organ in the body. The vessel wall is 5 times the size of the heart in mass and 6 times the size of a tennis court in area. The vessel wall is an active, integrated organ composed of three separate layers: intima, media and adventitia. Histologically, the endothelial cells are very specialized, metabolically active, polyhe...

BACKGROUND Tennis-teaching professionals represent a significant proportion of all avid tennis players worldwide, with 15,000 belonging to the largest professional organization, the United States Professional Tennis Association (USPTA). However, there is no epidemiologic study to date reporting the prevalence of musculoskeletal conditions in these tennis-teaching professionals. PURPOSE To inv...

The purpose of this study was to determine the acute effects of heavy resistance exercise on agility performance in court-sport athletes. Five men (age: 20.6 ± 1.9 years; body mass: 79.36 ± 11.74 kg; body height: 1.93 ± 0.09 m) and five women (age 21.2 ± 2.7 years; body mass: 65.8 ± 10.18 kg; body height 1.77 ± 0.08 m) volunteered to participate in the present study. All subjects were NCAA Divi...
