本研究目的是探討不同自覺能力對12分鐘跑走運動表現的影響，並比較 不同自覺能力之12分鐘跑走成績與Bruce法實測之最大攝氧量的相關。以國 立台灣師範大學男生為受試者，受試者以自我報告的方式填答自覺能力評量表 區分高低自覺能力。共計回收219份問卷，以全體受試者的中位數做為期準， 區分受試者為高自覺能力組或是低自覺能力組。願意參與本研究的受試者共計 44名，平均年齡20.48±1.53歲，身高170.78±5.07公分，體重65.86± 8.48公斤。全體受試者需接受實驗室最大攝氧量的測量與12分鐘跑走測驗。 以t考驗進行不同自覺能力12分鐘跑走成績表現的差異比較，結果發現高 自覺能力者的表現顯著優於低自覺能力者。並以皮爾遜積差相關法計算不同自 覺能力之12分鐘跑走與Bruce法實測之最大攝氧量的相關，結果顯示相關皆 達顯著水準；但相關係數間並沒有顥著差異存在。

　　　　　The purpose of this study was to examine the effect of perceived competence on exercise performance. Subjects were 44 healthy male college students (mean age= 20.48 ± 1.53 yrs). Based on subjects' perceived competence, they were categorized into two groups: 1)high perceived competence group；2) low perceived competence group. During the experiment, each subject performed one 12-minute walk-run test and one Bruce treadmill VO �� max test. The results indicated that high perceived competence subjects were better on 12 min walk-run performance than low perceived competence subjects, and there were no significant difference on relationship of 12 min walk-run test with maximal oxygen consumption between high and low perceived competence subjects. The results of this study fostered our understanding onthe effects of perceived competence on exercise performance, and provide scuentific basis for human performance tests.
