乒乓球教学训练的一条捷径

乒乓球教学训练中的多球训练是培养学生进攻动力定型的一个好办法。首先，要求学生集体挥拍，左脚在前右脚稍后一脚，两腿比肩略宽，两膝微屈，身体前倾略向右转，腹部内收，手腕向后引拍，拍面前倾，低于来球。挥拍击球后继续内收小臂至头前才停止，身体重心从右脚移至左脚，执拍手再向后引拍准备第二板。随后，教师在台子边上方放一筐乒乓球，不停地让学生做单球练习。先送直线让对手不停地正确进攻，形成动作定型后就可以全台喂球，让学生全台跑动正手进攻和侧身进攻。要求学生能攻斜线又能攻直线，经过一段时间的强化多球训练后，学生能…     

乒乓球技术训练与意识培养

众所周知,因为乒乓球运动给我们国家带来了许多的荣誉,还曾为国家的外交事业做出过重要贡献,同时深受广大人民群众的喜爱,所以被我们称之为国球。在体育电视节目中,我们经常看到运动员们打出精彩的比赛,而在普通乒乓球爱好者的运动中为何却少见甚至不见精彩的场面呢？本文将就此原因进行分析,并对解决方法进行探讨分析。     

浅谈青少年乒乓球运动员接发球的技术训练

随着乒乓球技术的发展,出现了许多新的发球技术,在比赛中显示了很大的威力,这就要求接发技术有自应的提高,然后,日前它却成为青少年乒乓球训练工作中的薄弱环节,亟需加强。     

少儿乒乓球运动员的早期训练

运动员的成材之路通常经过启蒙、基础、提高和完善4个阶段,少儿运动员的训练主要在前两段,即培养兴趣,打好基础。在培养兴趣方面,启发少儿对该项运动的理解和认识,开发专项智能,建立乒乓球运动意识,早期训练在少儿智能上投资收效甚佳。在基础训练阶段,建立和形成正确的技术动作,

业余体校和少儿培训班是对少儿乒乓运动员进行选材和培养的初级基础阶段,有着重要的启蒙指导作用.少儿乒乓球运动员科学选材的必要条件包括身体素质好、心理素质好、意志品质强、头脑灵活且手感好.少儿乒乓球训练注重基本技术的学习与训练,在初级训练过程中,动作结构和技术框架在平时的学习以及训练中逐渐形成,风格日趋显现.     

对网球运动员周期训练计划制定的研究

我国网球运动的起步和发展相对较晚,普及率低、发展速度缓慢。改革开放以来中国的体育事业取得长足的进步,尤其是竞技体育更是由＂旁观者＂、＂参与者＂逐渐转变为＂倡导者＂、＂主持人＂等角色,而网球运动更是在2004年至2008年间取得了＂三级跳＂式的发展。在其不断突破过程中,竞技网球的特异性始终冲击着我国网球运动的发展,从国际环境下的职业联赛到我国特色的网球运动,在训练角度上产生了激烈的碰撞。当今世界优秀的职业网球运动员大都打破了传统大周期训练安排定式,形成新的周期形态与训练模式。     

Glenohumeral internal rotation deficit in table tennis players

ABSTRACT

Table tennis requires rapid and extreme movements that may result in shoulder adaptations, such as glenohumeral internal rotation deficit, which is a risk factor for several injuries. This study compared range of motion of internal and external rotation and total rotation motion of glenohumeral joint between dominant and non-dominant shoulders of table tennis players. This is a cross-sectional observational study. Twenty healthy male table tennis players that were enrolled in an official table tennis league took part in this study (mean age: 22.9 ± 12.9 years, time of sports practice: 6.2 ± 7.12 years). Measurements of passive glenohumeral external rotation and internal rotation were taken with the individuals in the supine and sidelying positions. Total rotation motion was calculated by summing external and internal rotations. The dominant side showed decreased internal rotation when compared to non-dominant side in both supine (mean difference: 14.9°, p = 0.02) and sidelying positions (mean difference: 16.3°, p = 0.01). No significant difference (p > 0.05) was found for external rotation and total rotation motion between dominant and non-dominant shoulders. The findings indicate that table tennis players exhibit glenohumeral internal rotation deficit of dominant shoulder.     

我国青少年乒乓球运动员非智力因素研究

根据我国青少年乒乓球运动员特定的文化、环境特点,在我国非智力因素理论相关研究的基础上,运用文献资料、专家访谈、问卷调查和数理统计等方法,以八一队、山东队等5个乒乓球专业队10岁至17岁的青少年运动员为研究对象,分析非智力因素的差异性,为乒乓球运动员的训练和科学选材提供可靠依据。研究结果表明不同性别运动员中,成就动机、运动焦虑、运动自信心三个维度上存在显著性差异;不同年龄段运动员中,运动热情有非常显著的差异;不同训练年限的运动员中,运动独立性和运动坚持性两个维度存在显著性差异;不同级别运动员中,运动热情、注意稳定性和情绪稳定性三个维度有显著性差异。各级教练员根据乒乓球运动员非智力因素的差异性,从科学选材,到有侧重的加强青少年乒乓球运动员非智力因素的培养和强化,能在科学训练中更快更好的提升乒乓球竞技水平,缩短成才周期。

Utilization of cues in action anticipation in table tennis players

ABSTRACT

By manipulating the congruency between body kinematics and subsequent ball trajectory, this study investigated the anticipation capabilities of regional-level, college-level, and novice table tennis players using a full video simulation occluder paradigm. Participants watched footage containing congruent, incongruent, or no ball trajectory information, to predict the landing point of the ball. They were required to choose between two potential locations to make their prediction. Percent accuracy and relevant indexes (d-prime, criterion, effect size) were calculated for each condition. Results indicated that experienced table tennis players (both regional and college players) were superior to novices in the ability to anticipate ball trajectory using kinematic information, but no difference was found between regional-level and college-level players. The findings of this study further demonstrate the superior anticipation ability of experienced table tennis players. Furthermore, the present result suggests that there may be a certain “baseline” level of motor experience in racquet sports for effective action anticipation, while the addition of further motor experience does not appear to assist direction anticipation.

Tactical proficiency among table tennis players with and without intellectual disabilities

Abstract

The effect of intellectual impairment on sports performance has received limited attention by researchers. As a contribution to closing this gap, the purpose of the present investigation was to examine the differences in tactical proficiency between table tennis players with and without intellectual disabilities (ID). These groups were matched for training-volume and experience and consisted of 41 male (age = 27±8) and 30 female (age= 28±8) elite players with ID and a reference group of 12 male (age= 24±12) and 5 female (age= 20±9) players without ID. In two different test settings – one a World Championship and the other a training camp – the players in each group performed 60 semi-standardised rallies against the same opponent. Players were told that 12 sets of five identical services would be delivered, and their goal was to return the service with the intention of ‘winning the point’. The test results were validated for this study, to compute tactical proficiency scores (maximal score of eight points) for each player. A two-way Analysis of Variance (ANOVA) revealed significantly lower proficiency scores for players with ID than for those without ID. Repeated-measures ANOVA revealed that within each series of five rallies, starting with identical services, all participants were able to significantly improve their tactical proficiency gradually, but players without ID scored 4.3±0.5 from the first ball on, and while athletes with ID only 3.3±0.7 after five balls. The results of this study indicate that ID is associated with decreased tactical proficiency in table tennis.
