ABSTRACTThis study investigated split-step timing when returning serves and whether this timing is related to neuromechanical capabilities in world-class tennis players. In Experiment 1, the split-step timing of four groups of world-class players (male and female ATP/WTA seniors, and ITF juniors) was measured on court when returning serves of the same level players. The four groups initiated the split-step at a similar time, starting around the time ball-racket contact in the serve stroke and landed when early ball-flight information was available. In Experiment 2, the neuromechanical capabilities (leg stiffness and vertical jump performance) of a group of world-class players and three groups of less-skilled tennis players were examined. The results showed an increase in leg stiffness with an increase in the level of expertise. A cross-experiment analysis in world-class male players (ATP/ITF, n = 10) revealed that the timing of initial foot movement was significantly correlated with the leg stiffness (r2 = 0.54), with later lateral step after the serve in the players who had higher stiffness. The findings support the hypothesis that world-class tennis players adapt perceptual-motor control on the basis of their neuromechanical capabilities and maximise the time before initiating their interceptive action to rely on more reliable information. 相似文献

我国网球男选手竞技水平现状及相对落后原因分析 总被引：1，自引：0，他引：1
分析自1885年网球运动传入中国以来，特别是1973年以后，国际职业网球联合会实行新的排名法之后，我国网球男子排名（双打或单打）从未进入世界前一百名，和女子网球竞技水平相比形成“阴盛阳衰”。分析认为导致我国网球落后的因素有：教练员本身及其训练方面存在的问题；运动员综合素质较差；体育科技实施滞后；中国特色社会主义体育政策不够完善；历史、经济、自然条件的影响。应针对性地采取措施，以提高我国男子网球竞技水平成绩。 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

The importance of the International Tennis Federation's junior boys' circuit in the development of professional tennis players 总被引：1，自引：1，他引：0
The relationship between junior boys' tennis success, as measured by a top 20 International Tennis Federation's Junior Circuit (ITFJC) ranking, and subsequent ranking accomplishments in professional men's tennis is discussed. The names, countries, and birthdates of all players to achieve a top 20 ITFJC boys' year-end ranking from 1992 to 1998 were recorded. The progress of these players through the professional ranks was then tracked to the end of 2004. Results indicate that 91% of top 20-ranked boys achieved a professional men's ranking, while a stepwise regression analysis revealed junior ranking (JR) to be a predictor of future, professional ranking (beta = 0.232, r(2) = 0.054, p < 0.05). A regression equation [predicted professional rank = 78.17 + 6.31*(JR)] accounted for a significant amount of variance in professional ranking. For male players, therefore, the achievement of a top 20 junior ranking appears to be a reasonable yardstick for future, professional success. The type of surface upon which junior players develop their games was also shown to influence professional ranking highs, with play on clay courts or a combination of clay and hard courts helping to produce higher, professionally ranked players than hard court play alone (p< or = 0.01). 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

Official rankings are the most common measure of success in professional women’s tennis. Despite their importance for earning potential and tournament seeding, little is known about ranking trajectories of female players and their influence on career success. Our objective was to conduct a comprehensive study of the career progression of elite female tennis talent. The study examined the ranking trajectories of the top 250 female professionals between 1990 and 2015. Using regression modelling of yearly peak rankings, we found a strong association between the shape of the ranking trajectory and the highest career ranking earned. Players with the highest career peak ranking were the youngest when first ranked. For example, top 10 players were first ranked at age 15.5 years (99% CI = 14.8–15.9), 1.2 years (99% CI = 0.8–1.5) earlier than top 51–100 players. Top 10 players were also ranked in the top 100 longer than other players, holding a top 100 ranking until a mean age of 29.0 years (99% CI = 27.8–30.3) compared with age 24.4 years (99% CI = 23.7–25.2) for top 51–100 players. Ranking trajectories were more distinct with respect to player age than years from first ranking. The present study’s findings will be instructive for players, coaches, and administrators in setting goals and assessing athlete development in women’s tennis. 相似文献

ABSTRACTCompetitive balance is important because it enhances outcome uncertainty and therefore it promotes spectator interest, and encourages government investment in a sport. This article analyses the distribution of gold medals, medals, medal points and top eight points amongst nations in table tennis from 1988 to 2016 at the Olympic Games and the World Championships respectively. A normalised version of the Herfindahl-Hirschman Index and a coefficient of variation are calculated for each nation’s share of these performance indicators. The key findings are that China dominates both events, with successful female players being more dominant than their male counterparts. The competitive balance for gold medals has declined, whilst there is a trend towards improved competitive balance for top eight points for women, suggesting that more teams are featuring in the top eight (but not necessarily the top three) placings. This research has implications for the development of table tennis competitions. Compared to other racket sports, the issue of competitive imbalance in table tennis is particularly thorny, which threatens the long-term development of this sport. Accordingly, some measures are recommended for the International Olympic Committee and the International Table Tennis Federation to propel a more balanced development of international table tennis. 相似文献
