普通高校网球教学方式及网球基础项目训练初探 总被引：1，自引：0，他引：1
网球是由二或四名运动员用球拍往返击球的一项运动,是世界上重要球类项目之一。随着网球越来越受欢迎,高校体育课开始普及网球教学。网球是一项技术不受限制的运动。在整个网球教过程中,体育教师应该要结合网球运动的规律、教学规律以及自身的教学实践,以帮助高校网球教学质量的提高。本文就普通高校网球教学方式等方面进行简单论述,并说明部分网球基础项目训练的重点和方法。 相似文献

Abstract The dynamic properties of six types of tennis balls were measured using a force platform and high-speed digital video images of ball impacts on rigidly clamped tennis rackets. It was found that the coefficient of restitution reduced with velocity for impacts on a rigid surface or with a rigidly clamped tennis racket. Pressurized balls had the highest coefficient of restitution, which decreased by 20% when punctured. Pressureless balls had a coefficient of restitution approaching that of a punctured ball at high speeds. The dynamic stiffness of the ball or the ball-racket system increased with velocity and pressurized balls had the highest stiffness, which decreased by 35% when punctured. The characteristics of pressureless balls were shown to be similar to those of punctured balls at high velocity and it was found that lowering the string tension produced a smaller range of stiffness or coefficient of restitution. It was hypothesized that players might consider high ball stiffness to imply a high coefficient of restitution. Plots of coefficient of restitution versus stiffness confirmed the relationship and it was found that, generally, pressurized balls had a higher coefficient of restitution and stiffness than pressureless balls. The players might perceive these parameters through a combination of sound, vibration and perception of ball speed off the racket. 相似文献

Measurements are presented of the friction force acting on a tennis ball incident obliquely on the strings of a tennis racket.
This information, when combined with measurements of ball speed and spin, reveals details of the bounce process that have
not previously been observed and also provides the first measurements of the coefficient of sliding friction between a tennis
ball and the strings of a tennis racket. At angles of incidence less than about 40° to the string plane, the ball slides across
the strings during the whole bounce period. More commonly, the ball is incident at larger angles in which case the ball slides
across the string plane for a short distance before gripping the strings. While the bottom of the ball remains at rest on
the strings, the remainder of the ball continues to rotate for a short period, after which the ball suddenly releases its
grip and the bottom of the ball slides backwards on the string plane. The bounce angle depends mainly on the angle of incidence
and the rotation speed of the incident ball. Differences in bounce angle and spin off head-clamped and hand-held rackets are
also described. 相似文献

目的:研究一次网球比赛对青少年运动员血清心肌肌钙蛋白的影响,为网球运动训练监控提供参考依据。方法:以16名青少年网球运动员为研究对象,以一次三盘制网球教学比赛为运动手段,均进行三盘比赛,在比赛前、第一盘结束即刻、第二盘结束即刻、比赛结束即刻、比赛后4小时和24小时分别取静脉血,测定血清cTnT和cTnI。结果:从第二盘比赛结束开始,血清cTnT和cTnI均开始显著升高,比赛后4小时达到峰值,24小时候cTnT恢复到正常水平,而cTnI依然显著高于正常水平,性别间无显著性差异;比赛第二盘结束即刻、比赛结束即刻、比赛结束4小时、24小时,血清cTnT和cTnI超过心肌损伤界值的人数分别为3人、8人、15人、3人和6人、10人、15人、7人,超过急性心肌损伤临界值在比赛结束和结束4小时分别为3人、11人和3人、12人。在比赛结束即刻和比赛后4小时,比赛失败运动员血清cTnT和cTnI显著高于胜利运动员,而比赛后24小时,仅cTnI显著升高。结论:一次网球比赛可以诱导青少年运动员心肌肌钙蛋白释放显著增加。 相似文献
