※ 引述《BlueVenus (幽靜星球)》之銘言:
: 靠蠻力尻好像不是上上策
請不要把用力打球妖魔化說成靠蠻力
你就算沒學過能量守恆也應該有聽過吧
你要球飛得越遠就是要給它越多的能量
你要球得到越多的能量就是要讓棒子跟球接觸時速度越快越好
(而且讓棒子甜蜜點去打到球是最好的,這比較難算我就不解釋了)
你要讓棒子速度越快就是要越用力去加速棒子
所以用力才是重點
什麼用手腕壓棒子讓球產生倒旋的說法請不要再相信了
倒旋產生的浮力有效果但是效果不會太大
這些都是可以證明的物理原理
用力會產生的問題就是對棒子的控制力下降
但這是你想提昇打擊實力就必須克服的問題
就像投手不會一天到晚想要降球速求控球一樣
那麼該怎麼做呢?我可以用一個比喻
揮棒就像汽車在高速公路上跑一樣,揮棒速度就是車速
決定車速的因素是什麼呢?
第一個當然是車子本身的性能,可以對應到你的肌肉有多大塊
第二個因素比第一個更重要,就是路上有沒有塞車,對應你的揮棒順不順暢
如果塞車了,車子性能再好也是無用武之地
每個人都到達一定技術水準,都沒有塞車之後
比的就是肌肉和其他東西例如動態視力
揮棒要順就要從姿勢下手
你沒有po影片所以我就沒辦法繼續說什麼了
只能提一個大原則就是在揮棒軌跡最低點打到球,還有收棒收到肩膀以上
揮棒順是想把球打遠的基本條件
基本有了之後再來談跟球的方法和打擊策略等等比較難的問題
