想知道怎麼從監視器守備員變美技製造機嗎?

職棒場上常常看到防守專家們美技連連,不管是像前陣子完成千場出賽後風光退休的 "紅龜" 陳江和的飛身撲球。

又或者是像大聯盟內野教科書 Andrelton Simmons 的回身接球,再往二壘壘包做封殺的精采美技。

這些高難度的守備動作,困難的地方在於他們要在很短的時間內改變身體的方向,去接住速度飛快的小白球,這種能快速改變身體方向的能力,我們稱之為敏捷

要有良好的敏捷能力,其中一個非常重要的條件就是要有足夠的肌力,像影片中前海盜內野手 Josh Harrison 雖然在二三壘間遭到了夾殺,但他不停重複著向前衝刺、煞車並改變方向這幾個動作。

在這個過程中他的雙腿必須要有足夠的肌力,才能在最短的時間煞車並產生反方向的動量,否則就很可能在其中一次的變向過程中軟腳,跌個狗吃屎。

 

但是你如果看到這邊就開始狂練肌力,大概過了幾個月後你就會回來投訴我們,怎麼深蹲都做到兩倍體重了,守備時怎麼還是覺得身體重重的,守備範圍甚至只有左右兩步,每次都眼睜睜看著小白球從眼前飛過,千萬不要氣餒,因為影響敏捷能力還有一個重要的因素,那就是反應時間

前幾個禮拜在大聯盟的比賽中就曾經上演兩次投手躲子彈的戲碼,先來看看 Zack Godley 巧妙地躲開了頭部強襲球。

再來看看 Colin McHugh 的駭客任務式下腰。這個動作之所以這麼危險,就是因為球正好從脖子旁邊經過,這裡有著非常大條的頸動脈,擊中的後果不堪設想。

經過研究實測,球從被棒子擊中後飛到投手丘的位置,投手大約只有0.6秒的時間可以做出反應,而能及時做出這些閃避的動作,除了要有足夠的肌力,還要有非常好的反應能力

 

反應能力又能分成兩種,一種是有預期心理的反應,例如百米衝刺時,我們能預期等等聽到槍聲後要馬上作出起跑的動作。

另外一種則是無預期性的反應,例如在棒球場上守備的球員,他們無法預知這球是平飛球或是滾地球,打出來之後會飛多遠,當球以飛快的速度接近時,就要在零點零幾秒的時間內做出反應,決定要往哪個方向移動,要有如此優越的反應速度,當然不是光練肌力就有辦法達到,當然還需要有特定的反應訓練

要訓練無預期的反應其實很簡單,像影片中統一獅的一色優教練,雙手都各拿一顆球,在球員往前衝刺時,隨機拋下一顆球,這時球員就要在球落地前改變方向確實把球接起。

又或著可以利用一些器材輔助,像羽球國手周天成就會使用聲光刺激去進行反應訓練,有興趣的朋友可以到木曜4超玩的頻道看看他們與周天成的一日系列喔!

看看氣喘如牛的邰哥,就知道這些訓練有素的選手反應速度有多快了。

 

要如何知道自己的敏捷是否有在進步呢,敏捷測試中有一個非常著名的檢驗叫做 T-test,這個測試就像圖中一樣,會將角錐擺成一個 T字形,中間兩個角椎距離10碼 (9.14公尺),左右兩個則是各和中間的角錐距離5碼 (4.57公尺),從A角錐開始起跑並計時,往前碰到B角錐後往右邊碰D角椎,接者再往左碰到C角椎,回到B角椎後,最後再倒退跑過A角椎,並記錄整趟完成的時間,需要特別注意的是過程中都需要面對前方,也就是說在C、D角錐之間移動時,都會使用側併步的方式。

 

有良好的敏捷,除了有機會做出像 Nolan Arenado 的飛撲美技外。還可以確保自己在球場上的安全,畢竟小白球是不長眼睛的,當它朝你過來時如果你還像芭樂劇的主角只睜大眼睛什麼都不做的話,肯定是非常危險的。

 

英譯全文:

It’s not uncommon to see defensive experts show nice plays, such as diving catch by Jiang-He Chen, who just retired after finishing his 1000th game, or a backhand catch followed by in-time tag by Andrelton Simmons, who is recognized for his delicate defensive plays. The reason why these plays are difficult is that we need to re-direct our body in a short period of time to catch the ball coming our way really fast. This kind of capability is what we call “agility”.

To acquire agility, one of the most important factors is muscle strength. As we see in the video, Josh Harrison, the former Pittsburgh Pirates in-fielder, repeated his sprint, brake and redirection to avoid tag-out between second and third base. In this play, enough strength of his feet is required in order to stop and generate the momentum in the opposite way, otherwise he might fall down to dirt.

But you might sue us in the future if you start to do weight-lifting solely by viewing previous part of this video. You might miss lots of plays with the feeling that you’re unable to move your body or you could only move one or two steps away from where you stand before you say goodbye to the ball. Never give up, cauz there’s another factor contributing to agility, that is, reaction time.

Several weeks ago, there were two cases of how the pitcher avoided the bullet coming from the home plate in the Major League games. Let’s look at how Zack Godley dodged the line drive ball coming toward his head. Take another look at Collin McHugh makes a matrix-like move, he bend down to prevent the ball from kissing in his carotid artery and causing unimaginable consequences.

We could know from study that the pitcher has only roughly 0.6 second to react to the play after the ball is throttling its way from the home plate. Key factors contributing to these evasive actions are adequate muscle strength and good reaction.

We could further divide such reaction into that from “rehearsed agility” such as dashing right away upon hearing the gun shot in a 100-meter race or from “reactive agility” like playing in the baseball field. One could hardly predict a ball to be a fly ball or a ground ball, not to mention calculate its distance instantly with no mistake. When the ball is coming your way, there’s little time you could decide where to move and how you’re going to react. Instead of just improving your muscle strength, there’s definitely a kind of specific reaction training required to attain to react to the stimulus spontaneously.

Training how to react to “reactive agility” is quite easy. In the video, we could see the former Uni Lions coach 一色優, with his both hands holding balls, throws away the ball randomly while the player is dashing forward. The player has to accurately catch the ball with great maneuver before the ball reach to the ground. Or could train with the help of some instruments, Tien-Chen Chou, a national representative in badminton, trains his reaction to the stimulus made up by light and sound. Looking at how Chih-Yuan Tai breath in gasp could show how fast these well-trained professional players react. Check out their One Day Series in the channel MuYao4 for further information if you’re interested in this.

But how to know if we are improving or not? There’s a very famous test called “T-test”, where we put four corners into a T shape with one away from the center ten yards and the rest two of them away from the center five yards. We go from corner A to corner B and start timing, proceed rightwards to touch corner D, then leftwards to corner C, return to corner B, and go backwards to corner A. Timing record is jotted down. What we need to take care is we need to face to the front in the whole process, that is, we’ll take shuffle steps when moving between corner C and corner D.

Only with nice maneuver could we perform nice plays such as diving catch by Nolan Arenado and make us safe in the field. After all, balls are under no control after leaving home plate. It’s pretty dangerous if you stand inert while the ball is coming your way.
