※ 引述《c760709 (Pure Boy)》之銘言:
: 今天對平井的全壘打
: https://www.youtube.com/watch?v=_B5R4RWM8Io&t=242s
: 可以看出重心留得住 而且延伸的很好 有在中職的樣子
: 但自辦練習賽時的反方向二壘打
: https://youtu.be/dIlhFzQcZxo?t=49
: 延伸卻沒做出來 還像一朗打擊時會往前傾的動作
: 是因為要跟變化球導致的嗎?
: 現在大王是有跟球模式與強振模式的差距嗎?

一張圖解釋
擊球瞬間至延伸瞬間,身體重心與大腿仍在同一直線上,證明打擊機制仍維持得很好
差別有二,一在於肩線的角度來不及轉至完全正面,因此無法將球棒延伸至如下圖的完
全延伸
二是後腳腳板,同樣來不及轉向至正面,轉向必須抬起腳跟,靠腳尖做旋轉
據上圖來看,王的腳尖仍維持出棒抬腳前的位置,腳尖甚至還朝向三壘側,
顯然是球路以自己預期外的狀態進本壘板,在必須立即出棒的狀態下,前腳提前落地,
後腳轉向空間不足,導致身體也無法轉向至完美
但因為擊中甜蜜點,延伸也有,重心有保持,只是無法完全釋放力量的情況,仍有非常
好的結果
總結兩個案例,兩者皆有保持住重心,差在重心轉移與釋放的程度
下圖很顯然,該打席前面已經出現外角球,只是被王完全鎖到,能有充足的揮棒空間
上圖則是跟球到底,慢上一拍的結果
