两个主要方面。以下介绍简 单测定方法。振动状况：右手握紧球拍握把，抬起左脚跟，用拍面用力击打左脚跟底部， 感觉球拍的振动情况，好的拍振动小，差的拍振动利害并有难听的声响产生。刚韧度： 硬的球拍控球性能好，但击球费力；较软的拍子击球较省力，但控球性能差。左手抓 住拍头的顶部，右手握于握把低部，用右脚膝盖定住拍的中点，拍面与地面垂直，膝 盖向外用力，双手向内用力（如是碳拍可用尽全力，拍子不会坏的），观察拍子的变 形情况，硬的拍体变形小，软的拍体变形大。
发球属学很难，但比赛中最 容易发挥的技术，因它不受对手的牵制。曾用一法教人发球，效果尚可，如下：让 学习者握拍作把球拍从头上方扔过球网的动作（只是想象扔过网），而后找一比发 球击球点略高的树叉子，让练习者站好位置作从地面蹬起扔拍并击打树支的动作。
种很好的方法；底线抽击，初学者宜用关闭式步伐，而高水平球员采用开放 式步伐则更有利。又如，高水平球员双打比赛应双上网，而一般爱好者双上网则很 难赢得比赛。因此球员不可不加分析生搬硬套教科书上的说法，也不必视教科书上 的说法为金科玉律，应选择适合自己的合理的技术动作和战术。Post by jimfun

, you will get very happy and excited if you beat a player you never beat before(you have a break through). if you feel your 100% effort(performance) is not enough to beat a player , then you have to try 110% effort(I assume you improve 10% in this case), if still not enough, then 20%, 30% more....., if one day, your opponent still play the same high level tennis, and you beat him/her, then that means you really improve(or improve enough for beating him/her). so real good competition is cooperation between two opponents(actually prefer using "partners"), both players must be honest, or give each other all the problem they can give to let opponent solve(improve), give enough challenge to each other to make them better and tougher(physically and mentally tougher). | 欢迎光临 蒙城华人网 (https://www.sinoquebec.com/) | Powered by Discuz!
