运用文献资料法、数理统计法等对第16届亚运会男子网球单打技术进行对比分析,结果表明胜、负双方的一发成功率、一发成功次数、二发成功次数、截击直接得分不存在显著性差异（P〉0.05）,不是决定比赛胜负的关键因素。ACE球、双误、二发得分、网前得分、正手制胜分和反手制胜分存在显著性差异（P〈0.05）,是影响比赛胜负的重要因素。发球直接得分、一发得分、一发得分率、二发得分率、破发机会、破发成功率、破发成功次数、网前得分率、总得分、制胜分、非受迫性失误存在非常显著性差异（P〈0.01）,是影响比赛胜负的关键因素。 相似文献

Waiter’s serve (WS) is a specific tennis serve posture frequently observed in young players, and commonly considered as a technical error by tennis coaches. However, biomechanical impact of WS is unknown. The aims of this study were to identify the potential consequences of WS in young elite players relating to performance and injury risk, and to explain the kinematic causes of WS. Serve of 18 male junior elite players (Top 10 national French ranking, aged 12–15 years) was captured with a 20 camera, 200?Hz VICON MX motion analysis system. Depending on their serve technique, the players were divided into two groups (WS versus Normal Serve [NS]) by experienced coaches. Injury data were collected for each player during a 12-month-period following the motion capture. Normalized peak kinetic values of the dominant arm were calculated using inverse dynamics. In order to explain WS posture, upper limb kinematics were calculated during the cocking and the acceleration phases of the serve.

网球运动员反应判断与自信心的研究 总被引：1，自引：0，他引：1
网球技术动作的结果或运动成绩取决于若干因素--运动员对对方技术的感知、判断和运动员对自己动作的控制等环节,这些环节又直接与自信心和行为控制相关.研究专业网球运动员和业余网球运动员在这些环节中的反应时、反应准确度和信心程度.研究结果表明,专业网球运动员和业余网球运动员在反应时方面没有明显差异,但在反应准确度和信心程度上专业运动员显著高于业余运动员;左强势手运动员的反应时、反应准确度和信心程度略胜于右强势手运动员;反应时与反应准确度的相关关系大于反应时与信心程度的相关关系. 相似文献

Abstract The relationship between domestic professional tournament structure in women's tennis and the subsequent professional ranking success of a nation's female players is examined. The 2003 women's professional tennis tournament calendar provided the distribution of events in 33 countries. Criteria used to classify nations' success in women's professional tennis were as follows: number of players with Women's Tennis Association (WTA) points, number of players with Top 200 rankings, and the combined WTA ranking of a nation's Top 5 female players. Pearson product – moment correlations were performed between the number of tournaments and the three criteria. Considerable variation was observed in the number of events organized between nations (USA, n = 56; Thailand, n = 3). All countries had internationally ranked female players, and 24 nations had players ranked in the Top 200. Results revealed relationships between a nation's number of women's professional events and both that nation's number of professionally ranked players (r = 0.60; P < 0.01) and Top 200 players (r = 0.60; P < 0.01), as well as the combined ranking of their Top 5 players (r = ?0.52; P < 0.01). While a similar association was found between the number of professional events and players ranked in the men's game, there was no significant correlation between events held and the combined standing of nations' best five ranked players. Governing bodies and national associations in tennis should consider the provision of professional, domestic competition as key to the development of female tennis players. 相似文献

Abstract This study constructed a technique effectiveness evaluation formula for table tennis players based on the relationship between the scoring rate and usage rate of techniques and established the evaluation criteria through the examination of 224 matches of the world's top 35 players. It also built a competition performance formula with the score difference theory for the exploration of the correlation between player technique effectiveness and competition performance. The results showed the three indices – the technique effectiveness of the first and third strokes (TE1,3), the second and fourth strokes (TE2,4) and the after fourth strokes (TE>4) – could help better evaluate the technique effectiveness of elite players. The comparative analysis of Chinese elite table tennis players and players from other countries and regions revealed that Chinese players as a whole were “excellent” in all the examined techniques except in the male's “first and third strokes”; while players from other countries and regions were overall “general”. The case analysis of two world top players further indicated that correlation analysis of technique effectiveness and competition performance could help identify the technique indices highly correlated with player competition performance. 相似文献

ABSTRACTThis study is a systematic review of match analyses of table tennis that can be used for reference in China. Using the China National Knowledge Infrastructure (CNKI) as the search tool and “table tennis” as the keyword, we searched for all papers on table tennis published in Chinese core sports journals between 1980 and 2016. Then, we read through 1209 papers and divided them into different categories according to their publication types and main topics. Among them, 128 papers on match analyses met three inclusion criteria, and hence they were chosen as the reviewed studies. The results show that match analyses of table tennis in China have a sound research foundation, with the “three-phase evaluation method” and research on different topics playing an active role in helping coaches and players understand table tennis matches. Computer-aided match analysis not only enhanced the capacity and speed of data processing, but it also facilitated coaches’ and players’ understanding of tactical features by video feedback and multimedia presentation. Although match analyses of table tennis based on different theories or models are still in a preliminary stage, these studies are indeed pushing the development of this field. 相似文献

运用文献资料、录像观察、数理统计等研究方法对场地类型与网球运动员竞技能力发展的关系进行探讨。由于研究对象中以草地球场为主导训练环境的球员样本极少，本研究主要考察以硬地、红土场以及硬地和红土结合三种球场类型为主导训练场地类型的职业网球运动员在排名上是否存在差异。以1997—2005年ITF（国际网联）青年赛年度前10名运动员共87名男子职业球员的ATP排名进行方差分析。预分析发现，职业网球运动员获取最高职业排名的平均年限为5．8年，因此对本文研究对象ATP排名的数据获取底线为2009年。结果表明：红土场地训练环境成长的球员排名与另外两种场地环境下成才的球员最高职业排名具有显著性差异（P〈0．05，红土场球员排名平均数为121，标准差为131）。查阅国内外文献资料，从逻辑上分析了多年红土训练可能存在的额外训练效应，并提示场地因素可能成为预测职业网球运动员最高排名的指标之一。 相似文献
