对中国女子乒乓球运动员在比赛中前三板技战术的运用进行研究,并与世界优秀男子乒乓球运动员的发球、接发球和发球抢攻的技战术进行比较。结果表明:我国女子乒乓球运动员打法类型和前三板的技术风格与世界优秀男子运动员趋于一致,并具有明显的男性化特征,但在发球旋转与落点、接发球技术和发球抢攻等具体的技战术运用方面仍存在战术和意识上的差别。 相似文献

发球作为乒乓球比赛开始的第一拍,有着无可厚非的主动权.运动员发球技术的好坏,除了旋转的强弱,也体现在对落点的控制和变化上.发球好的运动员可以凭主观意识站在任何位置,发出任何线路、落点、旋转、弧线的球,通过高质量的发球可以直接得分或为下一板击球争取主动,还能起到控制或破坏对方进攻的作用.本文选取优秀男子乒乓球运动员张继科4场有代表性的比赛(表1),分析其发球效应与发球环节的关系,为广大运动员的训练提供参考. 相似文献

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

在网球这项运动里,对于中低水平的网球运动者网前属于是一个令人害怕的地方。但是了解了网前的基本截击技术并知道什么时候打球把球打到哪里,再掌握截击这项技术将会容易。初学者上网时会感觉到不知所措,这是很正常的现象。就击球时间而言,截击比底线击球需要更快的反应。此外面对快速的回击球也会出现害怕的情感。但是对于想要提高自己的竞技能力的初学者和中级水平的球员,拥有良好的网前截击技术是必需的。随着教学比赛,以及高校网球比赛的增多以及比赛的需要网前得分又是非常重要的得分手段。 相似文献

通过对第五届女足世界杯32场比赛111个进球的统计，表明下半场比赛的前15min是比赛进球的高峰期，总进球数的72．08％是在跑动进攻中完成的；超过3／5的进球都是在1～3人在1～15S中3次以下传球配合完成的，另外35．66％的进球通过定位球完成。完成全部进球的进攻战术结构模型有5种：后场抢断发动快攻个人突破射门得分是最基本的进攻模型、前场定位球快速发动射门得分是核心的进攻模型、中后场逐步推进发动阵地进攻射门得分是重要的进攻模型，边路进攻、边路传中和利用界外球进攻射门得分战术模型是有益的进攻战术补充，中场发动进攻中路传切配合进攻射门得分战术模型是最常用的战术方法。 相似文献

Comparing the pre- and post-impact ball and racquet kinematics of elite tennis players' first and second serves: a preliminary study 总被引：1，自引：0，他引：1

The aim of this study was to compare the pre- and post-impact three-dimensional kinematics of the ball and racquet during first and second serves performed by elite tennis players. Data were collected from four male and four female right-handed professional players during competition using two high-speed cameras (200 Hz). For each player, one first serve and one second serve from the 'deuce' or right service court that landed within the specified target area were analysed. To test for significant differences between the first and second serves, Wilcoxon tests (P < or = 0.05) were performed on selected parameters. The results indicate that the ball travelled forward and to the left during the flight phase of the toss in all but one trial. The average pre-impact ball forward location for the first serve was significantly more in front and had a higher associated forward ball velocity than the corresponding values for the second serve. On average, the decrease in post-impact ball speed from the first to the second serve was 24.1%. No significant differences between the first and second serves were found in the pre-impact racquet head speed and orientation, which was represented as a unit vector perpendicular to the racquet face. The major adjustments made by the players when going from the first to second serve were a decrease in pre-impact ball forward location (P < or = 0.01) and an increase in the pre-impact racquet vertical and lateral velocities (both P < or = 0.05). This implies that the players tossed the ball closer to the body and imparted topspin and sidespin on the ball by changing the racquet vertical and lateral velocities when going from the first to the second serve. 相似文献

Enhancing the understanding of coordination and variability in the tennis serve may be of interest to coaches as they work with players to improve performance. The current study examined coordinated joint rotations and variability in the lower limbs, trunk, serving arm and ball location in the elite female tennis serve. Pre-pubescent, pubescent and adult players performed maximal effort flat serves while a 22-camera 500 Hz motion analysis system captured three-dimensional body kinematics. Coordinated joint rotations in the lower limbs and trunk appeared most consistent at the time players left the ground, suggesting that they coordinate the proximal elements of the kinematic chain to ensure that they leave the ground at a consistent time, in a consistent posture. Variability in the two degrees of freedom at the elbow became significantly greater closer to impact in adults, possibly illustrating the mechanical adjustments (compensation) these players employed to manage the changing impact location from serve to serve. Despite the variable ball toss, the temporal composition of the serve was highly consistent and supports previous assertions that players use the location of the ball to regulate their movement. Future work should consider these associations in other populations, while coaches may use the current findings to improve female serve performance. 相似文献

Effect of skill decomposition on racket and ball kinematics of the elite junior tennis serve 总被引：1，自引：0，他引：1

Whole body kinematics of the tennis serve have been reported extensively in the literature, yet comparatively less information exists regarding the kinematic characteristics of the swing and toss. In attempting to develop consistency in placement of the toss and racket trajectory, coaches will often decompose the serve and practice it in separate parts. A 22-camera VICON MX motion analysis system, operating at 250 Hz, captured racket, ball and hand kinematics of the serves of five elite junior players under three conditions. The conditions were flat first serves (FS) directed to a 1 x 1 m target bordering the 'T' of the deuce service box, a ball toss (BT) in isolation and a free swing (SW) in isolation. Players were instructed to perform BT and SW as in the FS. Paired t-tests assessed within-group differences in hand, racket and ball kinematics between the discrete skill and the two decomposed conditions. Vertical displacement of the ball at its zenith increased significantly during BT compared with the FS and temporal associations between racket and ball motion during the FS (r = 0.861) were affected during task decomposition. This study questions the pervasive use of task decomposition in the development of the tennis serve. 相似文献
