Those of you following the World Cup know that at this stage there can be no more ____1____. ____2____ are broken during overtime play, or in a penalty kick shootout in which a goalkeeper's ability to anticipate the ball's flight can mean the difference between victory and ____3____. Now, scientists at Rensselaer Polytechnic Institute have discovered how a kicker's body can betray whether he's aiming left or right.
In a penalty shot, it's kicker versus goalkeeper. And with the shooter standing just 12 yards from the goal, that ball can touch net in about half a second. That's faster than a keeper can launch himself from the goal's center to either post. Which means that a goalkeeper has to start moving before the kicker's foot meets the ball. And he has to guess correctly which way to ____4____.
To figure out how good goalies might ____5____, scientists attached motion detectors to college-level penalty kickers. And they found a handful of indicators that reliably predict kick direction, such as the angle of the kicker's hips and how he ____6____ his supporting foot.
Good goalies may be able to read those ____7____. Meaning that they use their hands, and their heads.

若你正在追世界杯,就知道比賽進(jìn)行到現(xiàn)階段是不可能出現(xiàn)平局了。傷停補(bǔ)時階段的加時賽或點球大戰(zhàn)將會打破得分相同的平手局面,而守門員直接參與點球大戰(zhàn),他的技藝決定了一個球隊是勝出還是淘汰出局。如今,倫斯勒理工學(xué)院的科學(xué)家們發(fā)現(xiàn)足球運動員的身體動作會出賣他的意圖。 點球決勝就是罰點球者與守門員的一對一對決。踢球者站在離球門12碼的地方,而球射入網(wǎng)只需半秒鐘,而這遠(yuǎn)快于守門員從球門中心移動到任一側(cè)門柱處。這就意味著守門員在必須在踢球者出腳前就做出判斷,猜出踢球者的意圖從而向正確的方向撲救。 為了弄清楚守門員究竟會如何提高勝算,科學(xué)家們找來一些具有大學(xué)水平的點球踢球者并在他們身上裝上運動探測器。他們發(fā)現(xiàn)踢球者臀部的角度、以及如何固定支撐腳等一少部分動作可以用來準(zhǔn)確預(yù)測出他們的踢球方向。 優(yōu)秀的門將能夠讀出這些隱秘的身體暗示。也就是說,他們不僅四肢發(fā)達(dá),頭腦也不簡單哦。
