Yips最早來自高爾夫球術語,指的是發生於高爾夫球選手推桿時,肢體無法順暢控制的狀況;在生理上的症狀上,通常出現抽蓄、顫抖與僵硬等現象。除了高爾夫球選手外,其他競技運動的選手也被發現患有yips的個案,無法準確控制肢體的活動,進而影響運動表現導致成績明顯下滑,嚴重者甚至必須結束其運動員生涯。現有文獻對於YIPS的相關研究,以高爾夫球運動與高爾夫球選手為多數。透過肌電訊號測量(EMG)的實驗,患有YIPS的高爾夫球選手的上肢肌電訊號電位與握桿力測量結果明顯高於一般正常選手。若再細分可將YIPS患者分為第一類型的運動障礙(Type I)與第二類型的焦慮型態(Type II),同樣透過肌電訊號測量實驗,運動障礙類型與焦慮型態類型患者於生理特徵上確實又存在差異;在高低壓力情境比賽下,相較於運動障礙類型選手,患有焦慮型態類型的選手於非比賽時的表現優於比賽時的表現。治療YIPS方面,生理上可以透過神經醫學科的醫生給予治療,或藥物及其他治療方式獲得改善;而在心理方面,根據個案研究發現,藉由焦點解決引導意象(solution-focused guided imagery, SFGI)的療程,患者出現yips現象確實有得到明顯改善。
Yips is the word from golf terms, it indicates the limbs couldn't be controlled smoothly when the golf player putting stroke; symptoms usually are jerks, tremors and freezing in physiology. Yips cases are also discovered in other athletes, they couldn't control their limbs completely then make their performance not well anymore, more seriously, the athletes should end their athletes life. The literature for yips studies now existing are major on golf players. In the EMG experiment, the golf players suffering yips who's EMG signal and grip force are higher than general players obviously. More advanced, yips could be separated to physiology type (Type I) and anxiety type (Type II), and the difference exist between Type I and Type II's EMG experiment data. In a designed pressure game situation, compared to the players with Type I, the Type II players have a better performance in the low-pressure situation. About curing yips, it could be improved by neuroscience doctor's treatment, medicine or others in physiology; in psychology, according to case study, players suffering yips who has improved by accept the solution-focused guided imagery (SFGI) treatment.
