本研究目的為探討校園運動計畫介入對青少女運動知識、態度、自我效能、運動行為及心肺適能之影響效果。研究採類實驗設計，由某護校二年級班級中隨機各抽出兩班為實驗組及對照組，分別為88人及89人為研究對象。在計畫介入前先分別對二組學生進行運動知識、運動態度、運動自我效能、心肺適能活動指數及800公尺跑走前刨。前測後即針對實驗組學生進行12週運動計畫介入，對照組則不給予任何介入，在計畫介入完成後一週再對二組學生進行後利。資料以百分率、單因子變異數分析、配對t檢定、重複量數雙因子變異數分析箏統計方法進行分析及檢定。研究結果顯示實驗組學生介入後運動知識、運動態度、運動自我效能及800公尺跑走成績有正向的改變，且顯著高於對照組，但在代表運動行為的心肺適能活動指數，實驗組的變化並未顯著優於對照組。本研究之結果可提供學校衛生實務工作者在堆行校園運動計畫介入的參考。

　　　　　The purpose of this research was to explore the impact of a physical activity program on exercise knowledge, exercise attitude, exercise self-efficacy, exercise behavior, and cardiorespiratory fitness among female students. A vocational nursing school was selected by purposeful sampling. The experimental group (n = 88) and control group (n = 89) each contained two classes which were randomly selected from 11th grade classes in the vocational nursing school. All participants completed a structured questionnaire, including an exercise knowledge scale, an exercise attitude scale, an exercise self-efficacy scale, and a cardiorespiratory fitness activities scale at both the pre-test and the post-test stages. An 800-meter running test was used to test the cardiorespiratory fitness of participants. One week after the pre-test, the experimental group received a 12-week physical activity program, while the control group did not receive any intervention. The statistical analysis included percentage, mean, one-way ANOVA, pair-t test and repeated-measures two-way ANOVA. The results showed that improvements in exercise attitude, exercise self-efficacy, exercise knowledge and 800-meter running among the experimental group were significantly higher than among the control group. However, there was no significant effect on the score for cardiorespiratory fitness activities. The results of this research could be used as a reference for school health professionals to promote physical activities for female adolescents.
