Full textAbstract:
Aiming at the problems of poor image tracking effect, low precision, and long time in the process of image tracking of volleyball player’s arm hitting, a volleyball player's arm hitting image tracking method based on D-P algorithm is proposed. This paper analyzes the basic concept, basic principle, and basic equation of D-P algorithm and collects the arm stroke trajectory image of volleyball players under the three-dimensional visual model. Using wavelet multiscale decomposition method, the arm stroke trajectory of volleyball players is filtered, and the edge contour feature points of the arm stroke image of volleyball players are extracted. Using the gray histogram feature extraction method, the gray information of volleyball player's arm hitting trajectory image is enhanced. Combined with pixel adaptive enhancement technology, the key action feature points of volleyball player's arm hitting image trajectory are located. Based on D-P algorithm, the volleyball player's arm hitting image trajectory is adjusted and modified to realize the correct tracking of volleyball player's arm hitting image trajectory. The experimental results show that the trajectory tracking effect of volleyball player's arm hitting image is better, which can effectively improve the tracking accuracy and shorten the tracking time.

Full textAbstract:
The modern level of development of volleyball demands high-quality approach to physical fitness of the player. The efficiency of educational and training process and effectiveness of game activity of the volleyball player depends on his overall, technical and tactical and psychological physical conditioning. There is no effective technique considering specific features of players when training college teams now. During the main training time of the training process, much attention is paid to the technical and tactical actions of the player. For general and special physical training of volleyball players special conditions and additional training time are necessary. The lack of such conditions in most student volleyball teams significantly reduces the game result as a whole. In search of a way out of the current problem, we have developed a method of education of physical capable taking into account the peculiarities of game actions of volleyball players. On the basis of the individual approach, and taking into account the training conditions of the male team of OGU, a program of general and special physical training was drawn up for each volleyball player, depending on his playing function on the site. At the final stage of our experiment, the player 's physical and special-physical preparedness rates increased markedly. The level of endurance of anaerobic character, jump endurance, high-speed endurance of attacking players, “libero,” defenders increased by 30%. The level of speed and speed-force abilities of volleyball players with different game role increased from 25–37 %. The obtained data of the study showed that the use of the technique developed by us of physical preparation of volleyball player significantly improved physical preparation of each player with different roles, and performance of the team as a whole.Key words: volleyball, physical fitness, player role.

Full textAbstract:
The aim of this cross-sectional study was to examine relationships of external load variables between beach and indoor volleyball amongst individual positions on the team. The movements of eight beach and fourteen indoor female volleyball players were recorded during elite playoff matches; in total, 2,336 three-dimensional trajectories were analyzed. Time-outs and intervals between rallies or sets were excluded from active play time. In both beach and indoor volleyball, 80% of rallies lasted up to 10 s, and players covered 4.5 to 10 m of court during 60% of rally play. Differences in dependent variables of external load were found between independent variables of sports and player positions (p < 0.05). The distance covered in beach volleyball rallies and Player Load™ parameters was significantly higher by up to 23%. The unstable court surface with sand in beach volleyball elevated explosive Player Load™ (accelerations in all three orthogonal planes of motion higher than 3.5 m/s3) in beach volleyball players compared to those of players on stable flooring in indoor. While beach volleyball blocker and defender positions showed no significant difference in parameters between each other, they differed in all parameters when compared to player positions in indoor volleyball. Indoor blocker and libero reached higher loads than setter, outside and opposite positions in various parameters. Factors that influence external load include the larger relative court areas covered by each player in beach volleyball, complexity of players’ roles, and game strategy. This data adds to the knowledge of elite match demands in female volleyball. Specified agility-drill distances and times are essential for training optimization and must be supported by scientific observation. Researchers, coaches, and conditioning specialists should find this helpful for achieving a higher degree of training regulation.

Full textAbstract:
In order to improve the recognition ability of volleyball players’ spike take-off, and thus promote the accuracy of volleyball spike, this article puts forward the recognition technology of volleyball players’ spike take-off based on DTW algorithm combined with image recognition technology. The transmission relation model of detail features of volleyball players’ spike take-off action images is constructed, and the edge contour features of volleyball players’ spike take-off action images are detected and processed by detail wavelet feature decomposition and DWT algorithm. Using prior Atlas knowledge instead of dark primary color, the detailed information and color of the image are obtained. Through the method of filtering and maintaining, the image is guided to filter the details of the input volleyball player’s spike and take-off action image. Sobel operator is used to detect the weak edge information of the animation image. In the edge area, high-order moment feature decomposition and wavelet feature separation are used to enhance the details of the volleyball player’s spike and take-off action image and detect and enlarge the key action feature points, so as to improve the ability of enhancing and identifying the details of the action feature points of the image. The test shows that this method can effectively solve the noise and error in the process of recognizing the spike and take-off action of volleyball players, reduce the recognition error, and improve the ability to accurately locate the spike and take-off force point.
