本研究目的在於探討體適能課程與傳統體育課程對國中生健康體適能的效果差異並比較體適能課程與傳統體育課程教學活動對男、女生健康體適能增進效果是否有差異？研究對象以台南縣西港國中一年級中選擇一班為本研究實驗組，（男生18名，女生18名），另隨機抽樣一班為控制組（男生18名，女生18名）。控制組實施傳統體育課程教學，實驗組實施加入體適能活動之體適能課程教學。實驗進行十四週，每週二次，每次45分鐘，並進行前後測。所得資料以單因子共變數分析法進行檢測。以前測為共變數，比較兩班學生及兩班男、女生在BMI、坐姿體前彎、仰臥起坐、立定跳遠、心肺耐力等5項後測成績之差異。所獲得結果如下：
（一）實驗組經過十四週體適能課程教學後，坐姿體前彎、立定跳遠、仰臥起坐成績明顯優於控制組（p< .05）。BMI及心肺耐力表現則無差異。BMI主要受身體發育影響，實施何種課程影響不大。心肺功能提升是本課程可以再改進部份。
（二）實驗組不論男、女生經過十四週體適能課程教學後，在坐姿體前彎、立定跳遠、仰臥起坐成績明顯優於控制組（p< .05）。
（三）男生在立定跳遠成績差異幅度（p= .002）明顯優於女生（p= .022），原因可能是課程內容使男生彼此間產生競爭所導致。
本研究的結果顯示，只要利用一節體育課中的10-15分鐘課程實施體適能活動，一學期即可有效提升目前學生體適能。

ABSTRACT
　　The purpose of this research is to finding the advantage between traditional physi- cal education program and physical fitness program, and if the physical fitness program have di fference effect in boys and girls. We choice two classes of one grade in Sen kan junior high school to experiment in 14 weeks. One class performs the 45 minutes tradi- tion physical education program twice a week and the other performs the physical fitne- ss program in the same time. Each one class has 18 boys and 18 girls.
We collect the date of sit and reach forward, BMI, sit up, long jump and cardiova- scular endurance in these two classes before and after the experiment. Then we use the front test to be a covariance to analyze the post test with ANCOVA .We want to know if there are difference between students, boys, and girls in difference classes. After analyze these data, there are some results as follow
（1）14 weeks later，the physical fitness of physical fitness program class has significant better than traditional physical education program , and the physical fitness pro- gram class is significant better in sit and reach forward, long jump and sit up (p< .05). In BMI and cardiovascular endurance, there are no difference. May be BMI has been inference more by body grow than physical education program, a- nd this class have less inference in cardiovascular endurance.
（2）No matter boys or girls, the physical fitness of fitness program class has signi- ficant better then traditional program in sit and reach forward, long jump and sit up (p< .05).
（3）the boy’s long jump achievement(p= .002) gain more then the girl’s(p= .022). We consider that the mathod we used to gain power make boys competition, so they do harder.
The result of this research tells us that we can develop good physical fitness for our student after a season, if we can use 10-15 minute to do fitness exercise.
