我们常说，击球时要注重身体重心的调节，要有重心交换，要依靠腰部的转动来发力．尤其是在正手进攻的过程中，要先将重心放在右腿上，击球时要转腰，将重心转移到左腿上，这是正手进攻的基本动作。然而在比赛中，来球的落点是随时变化的，击球者几乎都是在跑动中击球，在很多情况下无法完成最“标准”的击球动作，此时就要靠运动员自身的调节，通过调整身体重心和击球动作，尽量合理地回球，提高稳定性. 相似文献

在乒乓球比赛中，有一些错误和毛病经常容易出现，但同时也很容易被选手们所忽视。对于这些问题，你千万不要以为“瑕不掩瑜”，相反应引起足够的重视。因为，在并非实力悬殊的比赛中，胜负往往取决于双方出现错误的多少，错误出现的越少，胜利的天平就会向你倾斜。反之，获胜的法码就会越来越轻。以下简介5种在乒乓球比赛中常见的错误，有技术方面，也有战术方面，供同仁们参考并指正。1．击球时忽视了头部的稳定在击球时，头部的稳定极为重要。不管你迎击何种来球，在击球前、击球中、击球后的短暂一刻，头部的位置应该是固定的。只有这样… 相似文献

O在击球区域之外击球时该如何保持身体平衡?1窍门就是“把球当作自己的舞伴”。——如果球偏离了自己的击球区域,也就是说高于胸部或低于膝关节,那么击球之后还能保持身体平衡吗?史密斯:当然可以。高点击球时站位幅度小一些有助于保持身体平衡,低点击球时,站位幅度则可以大一些。但是,在讲授平衡与站位时,有一点经常会被教练忽视,那就是底线相持球中的高点正手和双反应使用开放式站位来处理。低点击球时应使用中间式站位来处理。 相似文献

在击球时,乒乓球拍会产生一定的形变,其形变的大小反映了球拍受力的大小.运用动态应变测试系统测量了不同技术击球时球拍拍柄根部应变力的大小,结果表明:采用摩擦击球的方式击球,球拍形变幅度较大,获得的形变力也较大;撞击球的方式击球,球拍形变幅度小,震动较大,球拍击球瞬间所受的作用力时间相对较短. 相似文献

羽毛球击打后场高远球技术是羽毛球技术中一项重要技术，包括判断来球、移动脚步、挥拍击打等技术环节。笔者在教学中发现学生在学习羽毛球击打后场高远球技术时经常出现一些错误，笔者在下面将其一一列出并分析其原因和提出纠正方法。一、常见错误发生的原因１．准备姿势不正确接球前两脚站立位置过于靠前或身体重心过高或球拍放置过低，不利于到后场击球。交叉步技术，往往到达击球点时过晚。３．肘过低过偏击球时肘部过低，肘不正对击球方向，影响了击球质量。４．击球点偏后正确的击球点应该在头的前方，击球点偏后，回到对方的球过高，… 相似文献

乒乓球的削球打法一直以来都是中国乒乓球打法中的中坚力量,许多乒乓球世界冠军就是用削球打法取得冠军的成就。培养乒乓球运动员时,要注重从青少年开始培养削球打法技巧,这是当前乒乓球训练的重点。培养运动员快速移动能力是培养乒乓球削球打法的重中之重。 相似文献

It is hypothesized that live playing situations preceding an opponent's strokes in tennis have sufficient significance to provide expert players with anticipative cues to estimate accurately the spatiotemporal characteristics of oncoming ball trajectories. Seven participants (all expert tennis players) had to watch two players opposed in high, moderate, and low tactical significance situations terminated by a stroke delivered by one of the two players in the direction of the participants. The participants' vision was occluded 100 ms after the stroke, and they had to indicate the zone reached by the ball at the moment of its rebound. Results showed that the essential anticipative information is contained in the view of the opponent's stroke movements, whatever the tactical significance of the situation. 相似文献

Trunk rotation torques through the hip joints during the one- and two-handed backhand tennis strokes
The aim of the present study was to compare kinetically the roles of the lower extremities in generating trunk rotation in the tennis one-handed and two-handed backhand strokes. Fourteen male collegiate tennis players, seven with a preference for the one- and seven with a preference for the two-handed technique, were recruited as participants. The motion of each backhand stroke was filmed using two high-speed cine-cameras, and the ground reaction forces on the feet were measured separately using two force platforms to determine the joint moments and joint reaction forces at the hip, knee and ankle joints. A significant difference in hip joint moments between the two types of stroke was found in the phase from the start of forward rotation of the pelvis to the start of racket forward movement. For trunk rotation, the one-handed backhand players exerted a large joint moment in the front leg, whereas the two-handed backhand players exerted a large joint moment in the back leg. The exertion of a large hip joint moment in the latter stroke was comparable with the exertion in a forehand stroke reported previously. 相似文献

网球运动是一项技术含量非常高的体育项目,从生物力学的角度来讲,其完美的技术是力量和控制的有效结合,并能将受伤可能性减少至最低程度。网球技术复杂,在练习过程中不仅需要掌握某一个动作的完整技术,而且需要身体的各部位协调做功。正手击球是网球最为基本的一项技术,其结构一般分为准备姿势、引拍、向前挥拍、触球以及随挥五部分。本文主要根据生物力学中人体协调链的原理对其中触球环节的动作进行分析,希望能够弥补目前研究中的一些不足,促进练习者对网球动作更深层次的理解,进而提高其技术水平。 相似文献

Abstract The effectiveness of mental practice was studied when combined with three variables of instruction: audio, visual, and audio-visual presentations of the forehand tennis drive. An adaptation of the Broer-Miller tennis test was administered to 183 subjects prior to and following the training sessions. Subjects were divided into six experimental groups and one control group. Of the experimental groups, one heard, one viewed, and one both heard and viewed a sound filmstrip which described the tennis drive. Three similar experimental groups received parallel instruction but also engaged in 10-min. mental practice sessions immediately following their respective presentations. All six groups met three times a week for a period of 8 weeks. The three experimental groups which also engaged in mental practice showed a significant improvement in the execution of the forehand drive. Among the variables of instruction, audio used in conjunction with mental practice proved to be the most effective method for development of the forehand tennis stroke. 相似文献
