英文字幕:

A point guard. The hero if the hard court. A single player with unique skills -and a nervous system made of steel.

Hi, I'm Dr Greg Wells. Basketball is all about speed, power and intensity. And no one controls these factors more than the point guard. The point guard is the leader of the team, and so much more. Point guards need to survey an entire court at once. Like an air traffic controller at a busy airport, they're crafty multi-taskers.

To help navigate the action, they rely on extra-ocular muscles: Six muscles that move their eyes. The faster the eyes move, the more information that can be processed. Our retinas have 100 million photo-receptor cells. They convert light into nerve signals -and warnings.

But here's the challenge: a point guard has to watch that their eyes aren't giving away the play. This is where the game gets physical. Point guards need a lot of strength, but they're typically smaller than other forwards. Bulking up helps, but they also need to alter their brains to take the pain. The brain floods the body with pain-killing endorphins.

Endorphins are a similar chemical to the painkiller known as morphine. The hypothalamus, a gland in the base of the brain, shoots it into the nervous system - where it acts directly to block pain signals from reaching the brain. So by fighting their body's instinctual responses, point guards essentially re-wire their brains.

Use your peripheral vision... And master the brain, to block pain... That's how you shoot, for gold!

中文字幕:

控球后衛(wèi),球場(chǎng)上的英雄,擁有無(wú)與倫比的技巧和鋼鐵般的神經(jīng)系統(tǒng)。

我是維爾斯博士?;@球的決勝關(guān)鍵是速度、力量和沖力,控球后衛(wèi)尤其需要掌控這些因素。控球后衛(wèi)是球隊(duì)的領(lǐng)袖,不僅這樣,他們還要快速掃視全場(chǎng),如同機(jī)場(chǎng)的空中交通調(diào)度員。他們是機(jī)靈的多面手。

為了判斷球場(chǎng)形勢(shì),他們需要依靠眼外肌,即控制眼球的六塊肌肉。眼球動(dòng)得越快,能處理的訊息就越多。我們的視網(wǎng)膜共有一億個(gè)感光細(xì)胞。這些細(xì)胞把光轉(zhuǎn)化為神經(jīng)訊號(hào)和警告。

但有一個(gè)困難,控球后衛(wèi)必須小心,別讓眼睛出賣他們的計(jì)謀。這時(shí)就要拼力量。控球后衛(wèi)需要大量體能,但他們的體型一般比前鋒小,強(qiáng)壯些會(huì)有利,但他們也要讓大腦適應(yīng)疼痛。大腦向身體分泌大量能鎮(zhèn)痛的安多芬。

安多芬是一種類似止疼劑嗎啡的化學(xué)物質(zhì),位于丘腦下部的腦下垂體,向神經(jīng)系統(tǒng)分泌安多芬,它能直接阻止疼痛訊號(hào)到達(dá)大腦。通過(guò)抵抗身體本能反應(yīng),控球后衛(wèi)更改了大腦傳訊的線路。

運(yùn)用周邊視覺,并控制大腦,從而阻擋疼痛。金牌就可能成為囊中物。
