太极拳到底是什么？

[big bird]

這裡每個人都在努力尋找真理,如總統,小慧,witty,我,及其他.
只是每個人的背景,態度,方式不同而已.這不應該傷害討論的氣氛.

太極拳是非常困難的,也沒有足夠的科研,這是事實.
我有超過50本太極拳的書,只有一本用骨骼,肌肉原理講解,言之有物.
是外國人寫的,這便是太極拳的悲劇了.

太失望了!你們怎麼可以讓总统在這裡大放獗词?

备注：“大放厥词”原是用来赞美柳宗元写出了大量优美的文字，含褒义。现在这个成语的意义和色彩有了变化，常用来讽刺人大发议论，含贬义。

總統問了很多非常合理的問題,總統的邏輯思維也很清楚.
但他有太多的問題,我要回答便需寫一本書了.

簡單地說幾句:

剛體理論上沒有力的傳輸和蓄放的問題,但人是彈性體,有蓄放的能力,也有力傳輸效率的問題.
太極拳在這方面是很精細的.所以smilejohn的理解大致上沒問題,只是不夠細致而已.

力的產生是依靠肌肉收縮.將肌肉拉長(易筋經),將肌肉放鬆(太極拳),便增強肌肉蓄放的能力.加上有效傳輸系統(骨骼),太極拳的力(劲)是很厲害的.
太極拳說<用意不用力>,但對總統沒有必要說這些了.

不要低估'意'的重要性.Everything is in your mind.

太極拳被誤解的太多了,舉一個例:
<由着熟而渐悟懂劲>,普遍認為是<招熟>,是從<招>中<悟懂劲>.
事實<着>是<黏>,是從<沾粘连随>中<悟懂劲>.
從<招中悟懂劲>便走錯路了.

棚劲:我覺得我們打太極拳的欠總統一個滿意的答案.

比如我的前臂和上臂成90度角。你来向内推我的前臂。我依靠肱三头肌来对抗你的力（简化版，实际参与对抗的肌肉不止肱三）。但如果我的肱二头肌是完全放松的，那么你的力一撤，我的前臂就会在肱三头肌的作用下外展运动（前提是我无时间对你的撤力作出调整反应）。但如果我在对抗你外力的同时，肱二肱三同时紧张（其力之差可对抗你的外力），就给了肘关节一个阻抗。就类似于一个劲度系数比较大的弹簧，阻尼比较大。在你撤力的时候，我仍然会有一定的外展运动（原因仍然是我无法在你撤力瞬间做出反应来调整肌肉力量），但因为肱二头肌的阻抗作用，我外展的幅度会减少。这正如一个劲度系数大的弹簧，不会产生太大幅度的震荡。
...

總統,
這是完全錯誤的概念.
正確的骨骼結構有如CNTower或SkyDome(結構其實比他們更複雜).
骨與骨間靠韌帶(ligament)固定位置,外力經過骨骼結構傳到足底.
肌肉的參與不大,所以撤外力的时候肌肉沒有外展运动.
功力不夠便傳不到足底,要用肌肉了,便有外展运动.
這裡很多人都知道的.看來他們並不想告訴你呵

就您上面的这些话，完全违背现代解剖和力学。首先，肌腱韧带的强度，绝对不足以抵抗外力，原因很简单，因为他们的弹性非常有限（不信您去看猪的鸡的骨连接处）。如果肌腱的强度都达到能抵抗...

看起來你只是在瞎說.

How strong is the knee ligament? It can support and stablize a 200-300 lb body and sustain continuous pounding on the pavement several thousand times a day for a life span of 80 years.

How strong is bone: Bone is one of the strongest materials found in nature. One cubic inch of bone can withstand loads of at least 19,000 pounds (8,626 kilograms), which is approximately the weight of five standard-size pickup trucks. This is roughly four times the strength of concrete. Bone's resistance to load is equal to that of aluminum and light steel. Ounce for ounce, bone is actually stronger than steel and reinforced concrete since steel bars of comparable size would weigh four or five times as much as bone.

Besides, ligaments are not there to withstand the whole power of an external force. It holds the bones together, which ideally receive the force longitudinally (causing compression), not laterally (like a block, causing breakage).

Legendary power-lifter Ted Arcidi, himself no stranger to dense muscle mass, agrees that specializing in exercises that build greater tendon and ligament strength will enhance power and overall size.

a ligament is a band of tough, fibrous dense regular connective tissue comprising attenuated collagenous fibers. Ligaments are elastic; they gradually lengthen when under tension, and return to their original shape when the tension is removed. This is in contrast with tendons, which are inelastic.

1:34 自己看看.
在此狀態下肌肉還是鬆鬆的.
純用肌肉是沒有能力抵抗這種外力的.
主要是骨骼結構(骨骼+韧带將骨骼連接固定).

還是那一句, 有沒有可能做到, 實驗一下就成, 只在長篇大論的說, 說來說去都是沒結果的爭辯, 誰也不服誰。

雖是對夏蟲語冰,也只是盡力而為.
總統還是試一試便知.

總結一下,太极拳到底是什么？
太极拳是提高男士性能力的最佳秘密武器.

作為一個太极拳門外漢,你來到這個論壇提問,我們很客氣地歡迎你,也給你一些答案和提議.
我知道你沒有嘗試過我們的提議,你如何知道我們沒有嘗試過你的提議?你只是坐井觀天而已.

我只能建議我們抵制總統了.
YOU HAVE WORN OUT YOUR WELCOME.

You seem to be very proud of your logical thinking ability. Let me point out to you that you try to use your experiments to prove a negative. Wonder if you know that you cannot prove a negative using experiment? Do you know that even if something don't work in an experiment doesn't mean that it will not work?

You seem to be very proud of your scientific knowledge. Let me point out to you that when you devise an experiment, that experiment has to simulate the actual condition, or the results of your experiment is not valid? What you have tried to do is to localize (isolate) and test only a certain part of the body, but in Tai Chi we use the whole body? So your experiments are not valid at all.

The experiment that I have asked you to try is to prove the positive, and it simulates the actual condition, so my experiment is a valid experiment.

So much for 'President' as a scientific logical person!!!

這個我鑽成, 不過要時常練才有效; 像我這種懶散的人, 效果就......

我可要找嫂夫人督促你多練太极拳了!

那就過來玩玩, 看看誰揍誰

揍人我最喜歡

言傳身教,好!
Hyper確是正牌<打機佬>!

说这种话没有用。因为我不打架，怕把人打残。最近的炎热天气你们练拳吗，我有时一天练4个小时，出的汗几大杯。你要是有这个体力，就行。不用比了。

功夫這麼好但不能收發自如,可惜!

这两天仔细的想了想，认为太极拳可概括为：结构力学和材料力学

结构力学 ----- 形成攻防劲路；
材料力学 ----- 提高结构强度；

所有太极拳的理论和训练，都可以用这两种结构和材料方面的力学原理来解释。

還有:
newtonian nechanics
fluid nechanics
solid nechanics
cognitive psychology

[big bird]

是 mechanics

太極真的通了,可真是超博士級水平!
我只是說說罷了.
