But I disagree on one of your observations.
You said S&V can hold on until 60 years old. There might be a
misunderstanding. Most old guys are better at S&V because they
play doubles. Each guy only needs to cover half of the court,
and it's easier to S&V. If they play singles, it will be hard
to S&V since their movement is slower.
If you watch those 元老赛，you will find that Becker does baseline
mostly now, and Borg still sticks to baseline as he used to.

周末一场比赛，不是我的，一方（A）是强弱差距很大的，弱的女生基本没有stroke，

lob很稳定。强的女生是强3.5，正手反手stroke都不错，网前一般，反手失误稍稍有些

另外一方（B)两个，一老一少，看上去都是小时候练过的，动作很正规，根本不是3.0

别的，都在3.5-4.0,(我们这里很多人喜欢3.5这个级别，因为上4.0就比较难在local比

球非常快，
动作好看，底线正手暴力，反手单反稳定稍差，动作好像有些问题，反手slice不错；
年轻的full

怎么看A都没有希望，强的网前一般，弱的baseline就会lob。
结果最后A赢了B。

发帖数: 16592 | 42 我觉得发球还是挺不错的，动作流畅，timing也挺好，发球的几个要素都做的很不错，
细节上稍微改进一点可能结果就会马上不一样了。
1 击球点要再往前点，抛球太靠近底线了，没有给身体向前冲出去击球的space，比较
好的击球点是底线内2 feet左右，这样比较容易有投掷的那种感觉，这样你会发现你就
不会有身体向左边倒的情况了，因为那身体给你的击球手臂在让出空间，要不你就会抛
到身体右侧了。你看你发球结束后都是landing在baseline上，理论应该左脚landing在
baseline内半米左右，甚至右脚可以再往前跨一步，当然也可以不跨。
2 抛球时候可以重心从右脚往左脚移动过程中，也可以重心已经全部到左脚上，不过不
管哪种方法，基本是球离开手时候，重心已经落在左脚，至少是左右脚中间偏左脚的位
置，我暂停几次，捕捉看了你的trophy pose，我觉得你左脚脚跟抬起是可以的，但是
重心好像偏在右脚上，这样你跳起就是右脚发力了。右脚发力跳起，然后左脚landing
，身体在空中不容易平衡。
3 跳起后，平衡身体，右脚会向后，或者稍微右后踢起，或者甩起来一下。这样身体就

看到你的对手的优势和特点，对自己尽快来调整和适应吧。如果只打几个games的，有时候还没有调

发帖数: 4012 | 50 我没有说打完一个球“一定”要recover在 baseline里面。你的recover也要根据你的
shot 和对手的位置来recover的。你recover到任何位置，碰到比你高两个等级的，同
样被打暴。
你实在是要抬杠的话，我也没有什么耐心来解释。你说的 running 方向，我解释了你
的和我的不同，这里是不同的情况，没有谁对谁错，现在又搞 Mindset，说recover在
baseline里面很奇怪，奇怪就奇怪了，我也不解释了。
你不是我的学生，也不付费的，我也说的够多的了。你要是说我 running 没有解释清
楚，我还可以和你讨论，关于 recover 的东西，你觉得是什么就是什么了。 |
