排球后排扣球空中击球动作的三维高速录像分析 总被引：4，自引：0，他引：4
笔者运用三维高速摄影方法对男子排球运动员后排扣球空中击球动作进行了三维的运动学分析，目的在于揭示击球过程中身体各环节的运动特征，结果分析表明，后排扣球空中击球动作是以躯干的转体、收腹及伸肩动作用力带动肩、肘、腕、手依次用力成鞭打动作击球的三维运动，躯干转体动作的角速度大于收腹动作角速度，转体动作在后排扣球空中击球动作中占有重要地位。 相似文献

锻炼反手,提高网球技术 总被引：1，自引：0，他引：1
网球运动，大多数情况下是单手， 单侧的非对称性的身体运动。 当然也有球员使用双手握拍击球的方式，特别是在两侧击球时都用双手方式，但毕竟那还是极少数的。况且，大量的击球、发球还都是要用单手进行的。因此，网球选手通常都很注意加强击球一侧手臂的力量和速度，比如我们常常见到运动员用右手挥动加重的拍子来练习挥拍动作，以便提高击球的速度和力量。由于这种原因，网球选手典型的体形往往是一侧的肌肉强，而另一侧的肌肉相对较弱──仅从体形上看，这种训练已经违背了一般意义上的锻炼目的。实际上，只注意提高击球一侧手臂、手腕… 相似文献

网球发球动作的生物力学分析 总被引：1，自引：0，他引：1
0 前言 当今网坛,随着运动器材的不断改进,技术动作的不断革新,在比赛中发球已成为了一种重要的得分手段,发球技术也越来越受到选手们的重视。我国的网球选手与国外一流选手在技术上还存在着明显差距,然而我国现有对发球技术动作的研究和分析甚少,进行这方面研究探讨会对我国运动员提高成绩起到一定的帮助。当今网坛,普遍采用有引拍的动作,但国外一流选手采用无引拍的动作同样可完成速度快的大力发球,本文加以说明的是有引拍的动作指:向身体后上方的拉拍动作;无引拍动作指:直接向上方引至准备击球时搔背动作。本人试图对以上两种动作进行动作录像解析研究和分析,为运动员提出两种动作的运动生物力学特征,可能会提高我国网球技术水平提供参考依据。 相似文献

随着网球选手的击球更快更重,网球的比赛节奏也越来越快。比赛中选手们已经不仅仅是在比拼击球的质量,更是要比拼高强度的节奏中的稳定性,甚至是在被动,受迫情况下的回球成功率。要想拥有稳定的击球,就需要发展选手的体能与控制身体的能力。因此,训练选手在快速移动中的稳定平衡能力已经成为了当今网球研究的重要内容。通过对发展核心力量理论叙述以及对照分析在稳定和受迫情况下的击球形式来阐述发展核心力量对保证选手在快速移动中的动态平衡能力的重要性,为网球训练提供参考。 相似文献

ABSTRACTTalent detection intends to support lifelong sports participation, reduce dropouts and stimulate sports at the elite level. For this purpose it is important to reveal the specific profile which directs children to the sports that connect to their strengths and preferences. This study evaluated a perceptuomotor skills assessment as part of talent detection for table tennis, a sport in which perceptuomotor skills are considered essential to cope with the difficult technical aspects. Primary school children (n = 121) and gifted young table tennis players (n = 146) were assessed using the Dutch perceptuomotor skills assessment measuring “ball control” and “gross motor function”. A discriminant function analysis confirmed the added value by identifying primary school children fitting the table tennis perceptuomotor profile of the young gifted table tennis players (28%). General linear model analyses for the assessment’s individual test items showed that the table tennis players outperformed their primary school peers on all “ball control” items (P < 0.001). In conclusion, the assessment appears to be of added value for talent detection in table tennis at this young age. Longitudinal studies need to reveal the predictive value for sports participation and elite sports. 相似文献

Fatigue decreases skilled tennis performance 总被引：1，自引：1，他引：0
The aim of this study was to examine the effect of fatigue from maximal tennis hitting on skilled tennis performance. Eighteen senior county tennis players (9 males, 9 females) volunteered to participate in the study. Their mean (+/- s(mean)) age and body mass were as follows: males 20.7 +/- 0.9 years and 60.6 +/- 2.7 kg respectively, females 21.7 +/- 0.6 years and 71.5 +/- 1.8 kg respectively. The players undertook two performance tests, both against a tennis ball serving machine, on an indoor tennis surface: (1) a pre- and post-skill test of groundstrokes and service; (2) the Loughborough Intermittent Tennis Test (4 min work plus 40 s recovery) to volitional fatigue. Body mass decreased by 1.5% (P < 0.0001). Mean heart rates differed between rest, post-warm-up and all intermittent test values (P < 0.01), between the pre- and post-skill tests (P < 0.0001) and between bouts and recoveries (P < 0.01). Peak blood glucose and lactate concentrations were 5.9 mmol l(-1) (50% into the intermittent tennis test) and 9.6 +/- 0.9 mmol x l(-1) (25% into the test) respectively. Mean time to volitional fatigue was 35.4 +/- 4.6 min. Groundstroke hitting accuracy decreased by 69% from start to volitional fatigue in the intermittent test (P < 0.01). Service accuracy to the right court declined by 30% after the intermittent tennis test. The results of this study suggest that fatigue was accompanied by a decline in some but not all tennis skills. 相似文献

Simulated tennis matchplay in a controlled environment 总被引：2，自引：2，他引：0
The aim of this study was to develop an exercise protocol to simulate tennis matchplay on a 'category 2' surface. Match analyses were used to form the basis for the design of the protocol. The protocol involved playing against a tennis ball serving machine. Part A of the protocol comprised 92 min 46 s of simulated tennis matchplay; Part B consisted of continuous hitting to the point of 'volitional fatigue' or when the required hitting frequency for two consecutive ball feeds could no longer be maintained. Ten elite tennis players (5 males, 5 females) volunteered to participate in the study, which was performed on an indoor tennis court (Matchplay, En-Tout-Cas). Their age, body mass and estimated maximal oxygen uptake were as follows: males, 21.7 +/- 1.0 years, 73.6 +/- 2.6 kg and 58.0 +/- 1.7 ml x kg(-1) x min(-1), respectively; females, 21.9 +/- 1.3 years, 62.3 +/- 2.0 kg and 42.2 +/- 0.7 ml x kg x min(-1), respectively (mean +/- sx). Heart rate, change in body mass and time to volitional fatigue were monitored. The heart rate responses of the participants to the simulated matchplay (range: 140-157 beats x min(-1), 73-81% peak heart rate) were consistent with the results of previous studies, for 'actual' matchplay. This protocol was successful in simulating similar physiological responses in Part A to 'actual' matchplay on a 'category 2' surface, in a controlled environment; it was also a sensitive evaluation tool of skilled performance in Part B. The current protocol may be used as a baseline protocol for studying the influence of, for example, training and dietary intervention on performance. 相似文献
