※ 引述《abc12812 ()》之銘言： : http://tinyurl.com/p5ng8b : Hong Chih-Kuo is a flamethrowing lefty who routinely gets his fastball into : the mid-upper 90's with the Los Angeles Dodgers. These stats don't lie - Kuo : is a great pitcher, when healthy. Of course, that's the problem - Kuo has : suffered four surgeries on his throwing elbow. : A closer look at his pitching mechanics follows after the jump... : Kuo takes his throwing arm laterally behind his body quite a bit - better : known as "reverse rotation." When he returns it to the throwing side, it : causes a serious case of forearm flyout, which causes his olecranon process : to slam into its fossa and do serious injury to the elbow. : Kuo is pretty quick to the plate - 18-19 frames from maximial leg lift to : footplant, which is good. However, he also has serious timing issues at : footplant - check the still frame at the top of this article, or watch the : animated GIF a few times. It's clear that Kuo has late forearm turnover and : this causes unnecessary stress on his pitching elbow as it lays back in : external rotation. : Kuo has the "elbow lift" arm action, which is often referred to as a "short" : arm action (and loved by many traditional scouts), causing him to : horizontally flex the shoulder joint and stress the anterior portion of his : shoulder. : I don't know how many more surgeries Kuo can take, but if the definition of : insanity is doing something the same way over and over again and expecting : different results, Kuo might very well be on his way to the crazy house. 剛看到朋友轉的這篇文章這篇可以跟我自己blog的分析一同服用 http://blog.xuite.net/johnason/milktea/3779424 並且做個比對我個人對他的分析有以下看法他裡面提到的reverse rotation跟我的觀察一致我也有在我那篇文章提出這點但是我認為這個動作是他威力的來源加速過程需要的是時間與空間 Kuo進入發射動作前利用reverse rotate讓他能夠給球更多的加速空間他手臂的柔軟度給與了他這個額外的加速空間是讓他擁有世界頂級的速球品質的主要原因配合我在道奇板(#18uDZ8ma)去年kuo受傷時的文章一並服用他是否解決去年組織沾黏的後遺症(降低柔軟度) 以至於讓他無法負擔這個動作才是該了解的至於footplant這部分我覺得有點不知所云他挑了背後的連續動作gif來解釋這點然後說讀者可以用文頭第一張靜止圖來比對.... 這個動作應該用sideview吧 Kuo也不太能被分類為short arm action 這也與第一段的reverse rotation矛盾以上 -- 個人BBS「棒球」討論板 PTT2(ptt2.twbbs.org)->城市之戀->休閒農場->MilkTea My Blog http://blog.xuite.net/johnason/milktea -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.45.162.101 ※ 編輯: Johnason 來自: 114.45.162.101 (05/20 20:47)
