To exam the blind lid dark side of table tennis, we visited team USA Olympic player and college national double’s champion, Erica Wu. In competition, not only your table tennis ball fast, they’re difficult to predict. During her serve, Erica’s paddle spins on the ball at the rate over 3 thousand RPM, that’s rotation twice as fast as Major League curve ball. In although it, table tennis ball travels a much shorter distance than a baseball, top spin can cause the break as much as two feet. But since the surface of the ball is smooth and seamless, it is virtually impossible to read the spin with your eyes. This is why table tennis players like Erica relay on their ears for information. Picking up the several audible differences between the loud flat contact, which pods minimal spin, and softer brushing sound indicated lots of spin.
In identify rotation isn’t the only reason Erica relies on sound, study some shoots that auditory stimuli reaches the blink up to 3 hundredth seconds faster than visual stimuli. This help when dealing the ball that lead the paddle at speed over 70 miles an hour. Even the air drag reduces that speed high over than thirty percent, the shoot still can cover the nine foot table in less of eleven hundredth of the second. That’s on three times faster than a blinking an eye. With still little time to react, players naturally move back away from the table. For each the short foot for the ball to travel, Erica gains roughly thirteen percent more time to react, which is like OB table tennis players like Garaka sometimes plays far twenty feet behind the end of table. But even in that distance, they only have about half of a second to react. That’s comparable to return the one hundred fifty miles an hour tennisor. While returning the ball to the area, nearly fifty times smaller than the size of tennis court.

為了解開桌球的神秘面紗,我們邀請到奧運選手以及全國大學運動會連續兩屆冠軍 Erica Wu來做示範
桌球比賽難在球不但快,而且難以預測.在發球中,Erica 的 paddle spin 轉速高達每分鐘三千轉 ( 每秒 50 轉 ) ,速度相當於大聯盟的曲球,而且桌球的球距比棒球近得多,一顆上旋球最多兩英呎遠.
桌球的球面光滑無縫,所以難以用肉眼判斷旋轉.所以像 Erica 一樣的桌球選手都用耳朵來判斷.後面就是講大腦的處理上耳朵比眼睛快, 然後都桌球選手只有很短的時間對球做出反應, 就算像OB的Garaka退得這麼後面,也必須在0.5秒內出手,相當於網球選手對於一顆時速150英哩的球所出手的時間,但是回去的距離比網球場小50倍.
