本研究目的在於探討不同目標取向與自覺能力對自覺疲勞程度、運動表現以及12分鐘跑走及1.5英里跑走測驗預測最大攝氧量的影響。以運動目標取向量表、自覺體能量表與健康情形調查表篩選國立台灣師範大學健康男生44名為受試對象。平均年齡為20.48(1.53)歲，平均身高170.78(5.07)公分，平均體重 65.86(8.48)公斤。共分為四組，1.「高工作/低自我，高自覺能力」組，2.「高工作/低自我，低自覺能力」組，3.「高自我/低工作，高自覺能力」組，4.「高自我/低工作，低自覺能力」組。全體受試者先進行一次於跑步機上最大攝氧量之直接測量。接著採平衡次序 法，進行12分鐘跑走與1.5英里跑走，並於跑步後填RPE量表。結果顯示： 1.高自覺能力組的自覺疲勞程度低於低自覺能力組。12分鐘跑走的自覺疲勞程度低於1.5英里跑走。2.不論12分鐘跑走或1.5英里跑走，高自覺能力組的運動表現皆優於低自覺能力組。3.12分鐘跑走、1.5英里跑走成績與實測之最大攝氧量的相關皆達顯著水準，且並無顯著差異。就不同目標取向與自覺能力分組，12分鐘跑走、1.5英里跑走成績與實測之最大攝氧量的相關顯示：個人特質傾向工作取向者的相關較高，且皆達顯著水準。而個人特質傾向自我取向者的相關較低，特質傾向自我取向者除了低自覺能力組在1.5英里跑走成績與實測之最大攝氧量的相關達顯著，其餘皆未達顯著水準。

The purposes of this study were to examine the effects of goal orientation and perceived competence on rating of perceived exertion (RPE), exercise performance, and on predicting maximal oxygen consumption (VO2max) from 1.5 mile and 12-min walk-run tests. Subjects were 44 healthy male college students (mean age=20.48±1.53 yr). Based on subjects' goal orientation and perceived competence, they were categorized into four groups:1)high task/low ego and high perceived competence group;2) high task/low ego and low perceived competence group;3)high ego/low task and high perceived competence group;4)high ego/low task and low perceived competence group. During the experiment, each subject performed one Bruce treadmill VO2max test, one 12 min walk-run test and 1.5mile walk-run test. The RPE was recorded immediately after 12 min and 1.5 mile walk-run tests. The results indicated that high perceived competence group had lower RPE than low perceived competence group and 12 min walk-run test resulted lower RPE than 1.5 mile walk-run test. Results also revealed that high perceived competence group performed better than low perceived competence group on 12 min and 1.5 mile walk-run tests. Finally, no significant difference was found between relationships of 12 min and 1.5 mile walk-run performance with VO2max.
