Orlick 與Partington（1988）發現心理因素會影響運動表現，而許多個人或運動團隊項目則因心理介入，而得到幫助進而使個人潛力得到最大的發揮並創造佳績。Williams(1993)指出運動心理技能訓練對於運動員的最佳心理狀態擁有引導作用，它是運動心理諮商員、教練、運動員常提及與應用於競賽中的心理方法。
　　本研究目的為運用運動心理技能訓練，探討對跆拳道選手競賽心理能力與運動表現之影響。以兩名臺灣體院跆拳道選手為研究對象，進行18個月的運動心理技能訓練，訓練課程包含呼吸控制、自我覺察、理性情緒治療、負面思想停止法、以及自我談話等技術。透過觀察實地札記、與選手諮商討論逐字稿、競賽時觀察實地札記、賽後心智狀態訪談逐字稿、周遭他人（教練、隊友）看法逐字稿等三角檢證方式，了解選手於接受心理技能訓練後，競賽心理能力與運動表現之影響。結果發現兩位研究對象在競賽過程後自覺自信心、專注力皆有所提升，而在競賽時的焦慮則呈現降低的情形。在運動表現上，選手自覺及教練隊友主觀評價選手運動表現有向上提升。
