发帖数: 10018 | 1 Remedies: Wear shoes with curved lasts to allow pronation. Lightweight
trainers are often best, as they allow more foot motion. （看来HS4都不行了，
得hattori，宇宙鞋，五指鞋）
Also, check for flexibility on the medial (inner) side of the shoe.
Supinators should do extra stretching for the calves, hamstrings, quads and
iliotibial band. |

一般人都是外脚掌先着地，再翻到内脚掌，落实后脚踝的角度才决定是什么类型。我的

发帖数: 3845 | 20 经过一个冬天赛季，volley进步了，正手却退步了。最近在改正手，才慢慢体会到摔鞭
是什么感觉。以前正手没有摔鞭，用太多的arm，racquet drop不够。或者以前的
racquet drop是一个非常僵硬的手臂加手腕动作。最近发现小臂supination, 握拍一放
松，lead with palm, 自然而然形成racquet head drop加甩鞭效果(racquet lag)。不
要考虑球拍在哪里， lead with palm or wrist facing net， 自然而然就有了
buttcap facing net兼甩鞭加速度。天气暖和了希望多练练，看看效果如何。 |

发帖数: 3845 | 22 首先，解释一下为什么grip tension要很松，只有这样，向前挥拍的一瞬间，手臂手腕
已经向前，球拍却由于惯性还lag在后面，这个球拍lag非常重要(右臂自然有些
supination, 有些像向右转门把手，buttcap 自然向球的方向), 这个lag球拍最好不要
是forced的动作。
其次，触球瞬间不要抓紧，手腕千万不要用力。 |

不对？
首先单反必须比正手或双反握紧球拍多得多，这样胳膊在击球时就受到很大冲击力。
其次单反的follow through必须直臂，球拍刹不住车，上臂和wrist还会一定程度的
supination，肩膀也会受力，这个follow through的动作比双反或正手的follow

发帖数: 3845 | 30 I think it's because Djokovic's take back, his racquet head is pointing up
to the sky, so during racquet drop, plam (or racquet face) is not exactly
facing ground, there is about 15-30 degree angle facing ground. I think that
should be ok. As long as I don't supinate my arm on purpose, it should be
ok. |

发帖数: 3422 | 31 因为先需要有一个动作在手腕部lay back储能，然后才能释放出去形成鞭打效果。（如
果直接从slot动作开始，你只能让手腕主动硬坳拍子造成lay back stretch，但这样多
伤手腕啊。）
再强调一下，这个储能动作不主动发力，而且是wrist lay back motion (专业术语叫
wrist extension，不要按字面意思理解)，而不是手腕转动（not pronation/
supination）。如果靠手腕转动储能，受伤在所难免。（不要问我怎么知道的，哈哈。）
同意wellmoon说的：“向下的主要目的是为了下个阶段的手腕lay back，也叫pre-
stretch。”
Murray特别明显，请看下面慢动作里：
0：05 时候他的手腕并没有lay back
0：09 wrist snap之后进入slot 手腕lay back
0：10 击球点过后，windshield wiper过程中，手腕基本上没有lay back了

摘要
昆虫经过漫长的进化过程，获得了令人惊叹的飞行技巧，其高度的飞行机动性令现
代飞行器黯然失色。随着非定常流理论的完善，人们逐渐认识到非定常效应在昆虫
飞行中起十分重要的作用。实验中前缘涡及其产生机制的发现为解释昆虫是如何通
过振翅产生足够的升力奠定了基础。同时，借助于电子显微镜的帮助，人们认识到
昆虫的翅上存在若干智能微结构（the smart microair vehicles）,使昆虫的翅在
振动过程中自动地变形为适当的形状。本文通过综述近几十年，国内外的研究进展
，提出一些尚待解决的问题，希望对进一步深入的研究有所帮助。
