正手拍上旋不確定性

"Everybody's Talking About Topspin, I'm Not Sure If I'm Getting Any Topspin"

" 每個人都在談論上旋,我不確定是否得到任何上旋" 

Cause #1

Everybody's talking about topspin because it allows you to clear the net by a safe margin and still pull the ball back down in the court. You don't need to be a nuclear physicist to figure out what imparts topspin to a tennis ball. A clear understanding is all you need. 

原因#1

每個人談論上旋因為它讓你安全邊緣清除網障礙而且仍然把球拉回下來在球場上。 你不需要是一個核子物理學者來理解是什麼力量授予一個網球的上旋。你所需要的全部就是清楚的理解。

 

Solution A: First of all, what is topspin? Basically it's a ball that spins forward after the strings strike it. What's so great about a ball spinning forward? Once a ball starts to spin forward, it creates air pressure on top of the ball pushing it down.  

解決方案 A: 首先,什麼是上旋? 基本上它是在拍線擊球後, 向前快速旋轉的一個球。關於一個快速向前旋轉的球,有什麼那麼偉大嗎? 一旦一個球開始快速向前旋轉,它在球的頂端上創造氣壓將球壓下來。

This is the main reason everyone likes topspin. They don't have to be a Las Vegas type player who hits net skimmers, always flirting with danger. They can safely get the ball four to six feet over the net, with power and the ball is  still pulled back down before sailing long. To make a tennis ball spin forward, the racquet must be moving from low to high at contact. The racquet should drop at least one foot below the contact point before swinging forward to meet the ball.  

這是每個人喜歡上旋的主要理由。 他們不一定要成為是打擊網skimmer的一個拉斯維加斯式的球員-總是危險地擺動。他們能安全地把球打到網上 4-6 呎,藉由力量而球在長久航行之前仍然被拉回向下。為了要使網球球旋轉向前,網拍一定要在接觸點從低到高移動。 網拍在向前揮拍迎接來球之前,應該是在接觸點下面降低至少一呎。

 

This ensures a low to high swing. It's this low to high motion that will cause a brushing up at contact that makes the ball spin forward. The racquet must be in a vertical position (straight up and down) when contact is made.  

這樣確定了一次由低到高揮拍。 就是這一個由低到高的動作, 在接觸點引起了刷上去的效果可以使球向前旋轉. 當接觸的時候,網拍一定要在一個垂直的位置 (筆直上下)中。 

 

If the racquet is tilted or laid back at contact you do not get this brushing effect. The strings should make contact at the equator of the ball, that imaginary line around the center of the ball. If you try to come up and over the top and hit above the equator, you'll simply drive the ball into the net. This over the top theory is actually a common myth that will really hurt your ability to hit topspin consistently in the court.  

如果網拍在接觸球時是傾斜的或者被向後地放置, 你不會得到這一梳刷的效果。拍線應該在球的赤道,在球的中心周圍的那條想像的線與球接觸。 如果你試著在頂端上越過和打在赤道上面,你將只是把球打進入網內。這個超越頂端理論實際上是一個常見的謎思, 在球場上將真的傷害你一致性地打擊上旋球的能力。 

HOW TO HIT WITH TOPSPIN AND CONTROL 

Two Key Points To Concentrate On During Your Swing:

1. Swing low to high

2. Keep the racquet vertical through the contact area 

 

如何以上旋和控制擊球 

你的揮拍期間專注於二個重點:

1. 由低到高揮拍

2. 保持網拍垂直經過接觸區

 

         

Fig. 23 The racquet face is closed, the palm is down, the racquet is now set to be vertical at contact.

Fig. 24 The racquet is vertical at contact, striking the "equator" of the ball because the swing was from the shoulder without wrist and forearm rolling.

Fig. 25 This is a key photo, notice that the ball is gone and the racquet is still continuing on a low-to-high plane, remaining vertical. There has been no rolling over. But topspin has been parted.

Fig. 26 The racquet continues on the low-to-high plane, finishing high, the shoulder has been used as the hinge throughout the swing.

23 網拍面是關閉的,手掌在下,網拍現在被設定在接觸球時是垂直的。

24 網拍在接觸球時是垂直的,打擊球的 " 赤道 " 因為揮拍來自於肩膀而沒有手腕和前臂的旋轉。 

25 這是一張關鍵的相片,注意球不見了,而且網拍仍然繼續在一個由低到高的平面上,保持垂直。已經沒有旋轉超越, 但是上旋球已經被分開了。  

26 網拍繼續在低到高平面上,完成在高位,肩膀在整個揮拍過程已經被當作鉸鏈使用。

作為一個談網球拍|網球的部落格,實在有必要寫幾篇比較基本的介紹性文章,讓本部落格的讀者可以對網球拍|網球有較完整和正確的認識。不過說實在的越簡單的問題真的是越難回答..我今天想先就網球拍|網球的部分來談。網路上有關於網球拍|網球的文章不勝枚舉,這次我打算從一個非技術面的角度來看待網球拍|網球, 從網球拍|網球的內部抽離,站在一個更高的位置重新檢視它,希望可以由這樣的思考重新發現網球拍|網球的許多不同面貌!.網球拍|網球到底是什麼?請捫心自問,我這樣作,是否會幫到網球拍|網球需求者?如果不存在網球拍|網球需求,我是否還會這樣作?以上這段話不是我說的,也不是其他任何人的名言,這句話摘自官方。基本上官方對於網球拍|網球的立場,從這句話表露無遺!為什麼我們需要考慮網球拍|網球者的立場?答案非常簡單,因為沒有網球拍|網球者就沒有網球拍|網球,也不必網球拍|網球!減肥|瘦身|減重|瘦身餐|台中|減肥食譜|減肥日記|減肥瘦身|網球|網球拍|網球王子|網球拍拍|催眠|nlp|神經語言程式學|皮膚疾病|皮膚過敏|皮膚癢|皮膚病|美白|健康|醫療|疾病|
