※ 引述《abc12812 ()》之铭言： : 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. 刚看到朋友转的这篇文章 这篇可以跟我自己blog的分析一同服用 http://blog.xuite.net/johnason/milktea/3779424 并且做个比对 我个人对他的分析有以下看法 他里面提到的reverse rotation跟我的观察一致 我也有在我那篇文章提出这点 但是我认为这个动作是他威力的来源 加速过程需要的是时间与空间 Kuo进入发射动作前利用reverse rotate让他能够给球更多的加速空间 他手臂的柔软度给与了他这个额外的加速空间 是让他拥有世界顶级的速球品质的主要原因 配合我在道奇板(#18uDZ8ma)去年kuo受伤时的文章一并服用 他是否解决去年组织沾黏的後遗症(降低柔软度) 以至於让他无法负担这个动作 才是该了解的 至於footplant这部分我觉得有点不知所云 他挑了背後的连续动作gif来解释这点 然後说读者可以用文头第一张静止图来比对.... 这个动作应该用sideview吧 Kuo也不太能被分类为short arm action 这也与第一段的reverse rotation矛盾 以上 -- 个人BBS「棒球」讨论板 PTT2(ptt2.twbbs.org)->城市之恋->休闲农场->MilkTea My Blog http://blog.xuite.net/johnason/milktea --
