Once More Around the Park: A Baseball Reader

為了解決Pitching的問題，作者Angell, Roger 這樣論述：

The most celebrated baseball writer of our time has selected his favorite pieces from the last forty years to create Once More Around the Park, a definitive volume of his most memorable work. Mr. Angell includes writing never previously collected as well as selections from The Summer Game, Five S

easons, Late Innings, and Season Ticket. He brings back the extraordinary games, innings and performances that he has witnessed and written about so astutely and gracefully--＂The Interior Stadium,＂ on the complex attractions of baseball; ＂In the Country,＂ on a friendship that began with a fan letter

and took him far from the big stadiums and big money; ＂The Arm Talks,＂ on contemporary pitching strategy and the arrival of the split-finger delivery; and many others. Mr. Angell’s conversations with past and present players and managers, scouts and coaches, rookies and Hall of Famers enhance his o

wn expertise and critical appreciation, which define him as the game’s most useful and ardent fan. ＂Angell resembles a pitcher with pinpoint control. As a chronicler of the game, he’s in a class with Ring Lardner and Red Smith.＂--Newsweek. ＂Angell’s perceptions are fresh, vivid, and uncannily accura

te.... Only a fan who cares this much could observe so carefully and write so eloquently.＂--San Francisco Chronicle. ＂A triumph of art and grace.＂--Chicago Tribune Book World. In the course of a well-lived century, he established himself as. . .baseball’s finest, fondest chronicler. --The New Yorker

What puts Once More Around the Park on the big-league shelf is, above all, language and, after that, respect for the individuality and awe for the professionalism of its characters. Mr. Angell makes baseball sound like an art form; he demonstrates that writing about it is an art form, too.＂ --New Y

以預測-修正型直接施力沈浸邊界法探討紊流中鋸齒型電漿制動器對翼型動態失速的影響

為了解決Pitching的問題，作者陸秉鍵 這樣論述：

機翼中的升力伴隨著翼形攻角增加而增加。失速則是指當翼形的攻角增加至臨界攻角時，升力突然驟降的一個物理現象。動態失速是一個非線形的流體現象，因翼形攻角快速改變時所產生的機翼前緣渦流生成及運動，進而造成渦流延遲脫落的物理現象。使用電漿制動器作為主動式的流場控制，是近幾年來被廣泛研究的流場控制方法之一，透過主動式的電漿制動器可作為流場控制的方法之一，其目的是可以延遲失速現象的發生。本研究以預測-修正型直接施力沉浸邊界法來模擬流體與機翼間的交互作用，該方法可以在不需要重建網格的情況下模擬複雜的流固耦合問題。同時使用紊流模型-大渦模擬法模擬紊流場現象，並以輕度失速模型模擬動態失速的現象。本研究在驗證數

值模式階段分為三部分，第一部分驗證流在雷諾數100,000的情況下經過固定翼的升/阻力的值與Ohtake的研究符合。第二部分驗證數值電漿制動器，此處以流經過平板上的電漿制動器的情況下的速度分佈圖與Shyy的數值模型一致，第三部分驗證機翼上的線/鋸齒型電漿制動器，此處以流經過不同攻角機翼的升/阻力值來驗證其線/鋸齒型電漿制動器的改善效果符合Yoon的研究結論。本研究在動態失速情況下的研究，主要分成兩部分，第一部分證實在雷諾數100,000的情況下，線型電漿制動器在機翼弦長的0.1c位置可以有效提升機翼在翼型擺動的完整行程的升力/阻力比，並且分析其電漿制動器的頻率及電壓效應，發現改變電漿制動器的頻

率在提升機翼的效果上會更為顯著。第二部分根據研究結果發現鋸齒型電漿制動器對於改善紊流邊界層的效果有顯著提升。使用鋸齒型30°電漿制動器可以比線型電漿制動器提高20%以上的升力/阻力比，因此證實其鋸齒型電漿制動器可達成降低能耗目的。此外，鋸齒型30°電漿制動器在翼型擺動的下擺區段開始時，會產生新的渦流模式，該模式可以發現適當的前緣渦旋大小及強度，將會有助於提升機翼的升力/阻力比。

The Theory and Practice of Creative Coaching: Analysis and Methods

為了解決Pitching的問題，作者Turner, Arthur 這樣論述：

The Theory and Practice of Creative Coaching is a book that seeks to unearth new and exciting ways of coaching individuals in organisations and communities generally. Much of the practical writing about coaching is dominated by the use of coaching models and approaches and less work has been unde

rtaken exploring the human basis for this work. Taking its source of inspiration from a wide range of sources such as philosophy and the practical joys of nature this book will seek to fill some gaps in the ways in which practice unfolds. Much of work undertaken has been against the practical backdr

op of pitching theory against practice . In addition, more recently, this is set against trends involved in Higher Education whereby mature adults are undergoing over 12 months of training to achieve the nationally recognised ILM coaching qualifications at Levels 5 and 7. This represents contact wit

h a diverse set of cohorts of learners of over 300 students in the past 5 years for more than 100 contact hours per cohort. Mixing theory with practice is one of the strong points of these vocational qualifications ’producing’ highly motivated practitioners forging their understanding in the fulcrum

of reflective practice and individual reflexivity.Against this backdrop ideas, concepts and new ways of thinking have produced groups of coaches who are adept at utilising core and fundamental aspects of human nature to become successful coaches. Huge shifts in understanding have been made through

engaging in creative activities; to engaging in art, metaphors, nature, walking and unusual methods of engagement with a fellow human in a coaching setting. As a result, this book sheds light upon the use of creative techniques and begins to extend the possibilities for coaches and their clients. Pi

tched as a way in which peers and equals can work together to learn and develop alternative coaching approaches this book forms the platform for strong learning and an increased diversity of practice and understanding.

穿著不同釘數釘鞋對棒球投球肌肉活化的影響

為了解決Pitching的問題，作者黃彥慈 這樣論述：

摘要 研究目的：透過穿著不同釘數的釘鞋，以探討大專公開二級棒球投手穿著釘鞋的平衡、球速、好球率與各分期肌肉活化的差異。研究方法：實驗參與者為7名大專公開二級棒球投手，分別穿著9爪釘、7爪釘、7爪釘與6爪釘進行投球，每款鞋子各投20球，並透過無線表面肌電儀（Delsys, free EMG)蒐集投球時下肢的肌電訊號。統計方法：以重複樣本次序變數的無母數統計方法分析(Friedman Test)，進行投球時釘鞋與平衡、球速、好球率與各分期肌肉活化之比較。研究結果：4種鞋款對於左右腳的平衡能力未達顯著差異；對於球速與好球率也未達顯著差異；在投球動作分期當中，4款鞋的肌肉活化在手臂上舉期時，軸

心腳的股直肌達顯著差異(p=.002)，手臂加速期軸心腳的股外側肌達顯著差異(p=.002)，手臂減速期軸心腳的股外側肌及自由腳的股直肌達顯著差異(p=.001；p=.003)，跟隨期軸心腳的股外側肌、自由腳的股外側肌達顯著差異(p=.001；p=.001)，自由腳的股直肌與脛前肌也達顯著差異 (p=.001；p=.003)。結論：研究結果顯示，投球動作因人而異，釘鞋的影響在短局數中效果可能不明顯，足跟區只有1釘的釘鞋肌電訊號偏小，導致不好發力，對於投球的運動表現無法增加效益。關鍵詞：下肢、平衡、投手丘、肌電訊號
