网球运动要求在对抗中应想尽一切办法调动对手，尽力上网击球，而双手反拍打法正是具有凶狠、刁难、隐蔽性强的特点。针对我国网球运动员身材偏矮、力量偏小，但步伐灵活这一特点，选择双手反拍打法是比较合适的。 相似文献

底线反手技术在网球技术中是十分重要的。网球反手击球有两种方式,一种单手反拍技术(以下简称单反),另一种双手反拍技术(以下简称双反)。大家对两种反拍技术都各持己见,到底哪种技术更为先进更为合理没有科学依据。以前双反技术多出现在女子网坛,但是现在双反技术在男子网坛也颇为盛行,本文以男子网球从单反、双反握拍到击球技术等方面,对两种击球方式进行综合对比分析,指引网球初学者和爱好者结合自身的打法特点选择适合的反拍击球技术。 相似文献

目前,普通高校大学生的网球教学效果不尽人意,尤其是网球的正反手技术的掌握和运用极其不平衡,这直接影响了学生网球技术水平的提高和发展.针对这一现象,打破传统的网球正反手教学顺序(先学习正手抽球技术后学习双手反手抽球技术),提出"先学习双手反手抽球技术后学习正手抽球技术"的教学方法,意欲通过改变网球正反手的教学顺序达到提高... 相似文献

通过对辽宁省高校任教的网球专业及非网球专业教师的调查,发现单手反拍打法在辽宁省高校网球教学中较少运用,网球专业教师中采用单手反拍打法的仅有几人,且教学大纲中也无明确学时规定,这都严重地制约了单手拍技术在高校的发展。本文针对此现状进行研究,并提出相应的建议,以期为提高单手反拍打法在高校网球教学中的运用提供借鉴。 相似文献

本文通过对世界网坛职业运动员,及对黑龙江省第六届高校网球公开赛所有参赛选手的调查,发现单手反拍打法在国际网坛已被越来越多的球员所运用,尤其在男子球员中占据着重要地位,但在黑龙江省却被较少的运用。而网球专业教师中采用单手反拍打法的仅有2人,且专门院校的教学大纲中也无明确学时规定,这都严重的制约了单手反拍技术在黑龙江省的发展。本文针对此现状进行研究得出结论,提出了相应的建议,为提高单手反拍打法在黑龙江省网球界的地位提供了借鉴作用。 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

Abstract The main aim of this study was to identify and compare ball speed and hitting accuracy of forehand and backhand groundstrokes between ATP professionals (elite) and high-performance youth players when shots were played cross-court and down the line to a target square. Six elite and seven high-performance tennis players volunteered to participate in the study. A Doppler-radar device and a digital video camera, operating at 120 frames per second, were used to measure ball speed and accuracy of forehand and backhand groundstrokes in the respective situation (cross-court and down the line). The results of 1040 measured groundstrokes indicate that the ball speed of the forehand and the backhand ground stroke was higher in the elite group when analysing (1) all valid shots, (2) the six fastest shots, and (3) the six most accurate shots (all P < 0.05). In addition, all players achieved a higher forehand speed compared with their backhand when balls were directed cross-court (P < 0.01). The participants demonstrated similar ability when considering accuracy of their groundstrokes (P > 0.05). However, a group difference for accuracy was identified when considering the six fastest forehand shots (P<0.05), and the forehand cross-court stroke was played more accurately than the backhand cross-court stroke by both groups (valid shots and six most accurate shots, P<0.05). Moreover, there was no evidence that players who impacted the ball faster were any less accurate than those who impacted the ball more slowly. Analyses for participants actually revealed a negative correlation between ball speed and mean radial error (accuracy) for the backhand down the line (r= ? 0.77, P<0.01). According to the results of this study, ball speed seems to be the determining factor that separates elite from sub-elite tennis players. 相似文献

The study investigated differences in the one- (SH) and two-handed (DH) backhands when hit flat, across-court (AC) and down-the-line (DL), and with heavy topspin DL (TDL). The ability to disguise each of these backhands when hitting the above strokes was also assessed. Eighteen college-level male tennis players, identified as having a high performance topspin SH (n = 6) or DH (n = 12) backhand drive, participated in the study. Players were required to hit three AC, DL and TDL backhands from the baseline with their preferred technique, while being filmed with two high-speed video cameras operating at 200 Hz. The highest horizontal velocity backhand for each stroke was analysed. Results indicated that the sequential coordination of five body segments (hips, shoulder, upper arm, forearm, and hand/racquet rotations) was required for the execution of the SH stroke. The same number of segments were generally coordinated in the DH stroke (hips, shoulders, and varying degrees of upper arm and forearm rotations followed by hand/racquet movement). Mature players produced comparable racquet horizontal velocities 0.005 s prior to impact using either the SH or DH backhand technique. The SH backhand was characterised by a more rotated shoulder alignment than the DH stroke (SH: 119.1 degrees; DH: 83.4 degrees) at the completion of the backswing. At impact the ball was impacted further in front (SH: 0.59 m: DH: 0.40 m) and a similar distance to the side of the body (SH: 0.75 m: DH: 0.70 m). Players using the DH backhand technique delayed the horizontal acceleration of the racquet towards the ball (SH: 0.13 s: DH: 0.08 s prior to impact) and thus were capable of displaying a similar hitting motion closer to impact than players with a SH technique. 相似文献

文章通过实践练习和理论分析认为,"直拍横削结合推攻打法"的构思是可行的,它能在反手位用正面反胶进行反手攻和加力推,增强了削球打法反手位的进攻实力;能在反手位用球拍正面反胶和反面长胶两面不同性能的旋转变化,干扰对方,为进攻创造机会;还能在反手位用正面反胶和反面长胶进行推挡、推挤、磕球、拨球等技术,积极多变地防御对方的发球抢攻、搓中突击,从而为削球打法找出一条新路,走出低谷,争取更好成绩。 相似文献
