Re: 彭政閔 vs 凱撒
※ 引述《benda (benda)》之銘言:
: 在這裡必須強調的是,美國人非常要求打者擊球接觸的瞬間時必須一定要是
: palm up/palm down,左手心朝下右手心朝上,但是國內的教練或是球評經
: 常提到翻手腕的打擊,底下有個我在棒球版看到的例子:
: http://www.cis.nctu.edu.tw/~is87084/page_hit1.htm
: 在這網頁提到的在翻手腕的瞬間擊球是絕對錯誤的觀念,因為一但翻手腕,
: 不管你的翻手腕技巧多好,揮擊平面或多或少都會有不順,擊球點很容易偏
: 差。
: 手腕的應用大概是國內跟我看到的美國人觀念差異最大的地方,美國人絕大
: 部分很少提到手腕的應用,更別提什麼翻手腕擊球。
這邊推荐Ted Williams 的Science of Hitting
這本書裡也有提到
Ted Williams 認為擊球瞬間時是"wrist unbroken"
他還和一些不這麼認為的球員辯論過
這裡還有另外一個站

點左邊的Truisms & Fallacies 再點右邊的
"Roll your wrist at contact"
第一段
Rolling the wrists before or near contact is a serious mechanical flaw
that results in loss of power and consistency. During my research,
which related to how energy is transferred in the swing, I concluded
that premature rolling of the wrists is a killer flaw. In the study,
I identified 26 major league baseball players players whose wrists
consistently started to roll prior to contact.
The batting average for this group was .224 and their average homerun
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
production was 2.1 per year. Three year later, only 4 of those players
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
were still in the major leagues.
