Djokovic And Nadal In The Research Of The Movement Characteristics Of The 2013 China Open

Research objective:the preliminary work of world elite male tennis athletes running speed of the standard, Djokovic and Nadal running characteristics, provide the basis information for the research on the characteristics ofthe tennis movement, provides the reference for the men’s tennis playerstraining in china.The object of study:in 2013 the net Djokovic and Nadal all video game, a total of 9 matches, selected and studied the video in 8 bit ATP top 50tennis players.Research methods:the use of video game, through the SIMI-Scoutanalysis system to obtain the original data and sorting. Using SPSS forwindows 12 Zhongbai quantile method of data statistics processing. According to the original data of 8 ATP top 50 tennis players makerunning speed in standard and Djokovic and Nadal were runningcharacteri stics in the course of the game using the standard analysis.The results of the study:1. The running speed data by using the percentile percentile location: P98=6.7, P95= 5.6, P75= 4.5, P50= 3.3, P25= 2.5;2. Novak djokovic is averaging all serve to run 956 meters, the high strength ran 4.4%, strength in the aerobic run 16.7%, aerobic running low intensity 78.9%, averaging all receiving running 1309 meters, high intensity running 6.1%, strength in the aerobic run 21.4%, aerobic run low intensity (72.5%);3. Always run 1255 meters, high intensity running 5.7%, strength in the aerobic run 19%, aerobic running low intensity 75.3%, averaging all receiving running 1294 meters, high intensity running 7.1%, strength in the aerobic run 25.8%, aerobic run low intensity (67.1%);4.

Djokovic and nadal’s serve running in aerobic and strength of high strength are below the receiving department, receiving department need more running;3. Nadal game running distance than djokovic, nadal running in aerobic and strength of high strength ratio are higher than djokovic, djokovic organization attack ability is strong, run more efficiently, nadal’s defensive ability is stronger, ability to run more prominent;4. Serve the movement path relative to the farther before receiving the trajectory, serve the trajectory of figure more concentrated, nadal movement trajectory than djokovic, djokovic attacks more effectively, attacking play a more prominent, nadal running more active, more outstanding defensive play.
