本研究目的在比較十二週健身房課程前、後健康體適能的差異情形。以長榮大學95學年度第二學期二、三年級體育課專項選修健康體適能班之學生92名（男生35名、女生57名）為研究對象，男生平均年齡為18.4±0.55歲，身高為1.70±0.55公分，體重為61.8±9.8；男生平均年齡為18.51±0.8歲，身高為1.62±0.08公分，體重為55.46±11.19。健康體適能測驗項目包括身體質量指數、坐姿體前彎、屈膝仰臥起坐、立定跳遠與登階測驗。所測得之各項健康體適能成績以相依樣本t-test考驗統計方法進行分析，研究結果如下：男生各項健康體適能前、後測驗成績在一分鐘仰臥起坐與登階測驗等項目達顯著差異，而女生在一分鐘仰臥起坐、立定跳遠與登階測驗階等項目達顯著差異，亦即其後測成績顯著地比前測成績進步，也就是其教學有改善效果。
