本研究的目的在了解新竹市某國中七年級學生體適能檢測成績與其學業成績之相關情形。研究對象為男生395位、女生362位，共757位。依教育部體適能網站公告之檢測項目：身體質量指數、坐姿體前彎、立定跳遠、一分鐘仰臥起坐、男生1600公尺跑走、女生800公尺跑走進行施測，並經標準化轉換分數後，與100學年度第一學期語文領域及數學領域之學期成績，依SPSS統計軟體進行統計分析探討其相關性。研究結果顯示：在身體質量指數項目，男生過重的比例27.0%明顯高於女生的17.4%；而女生過輕的比例20.5%也明顯高於男生的13.0%，學校及家長應注意是否有男生營養過甚、女生營養不良之現象。其他四項體適能項目：坐姿體前彎、立定跳遠、一分鐘仰臥起坐、男生1600公尺、女生800公尺跑走，男女生成績達教育部公告之全國常模PR25以上者，比例均超過60%。而體適能與學業成績之相關性，經皮爾森積差相關比較後，男生體適能與語文成績(r=.161，p＜.01)、數學成績(r=.198，p＜.01)，女生體適能與語文成績(r=.154，p＜.01)、數學成績(r=.107，p＜.05)，皆達顯著相關，尤其是男生在體適能與數學成績中的相關係數是最高的，其強度達中度相關；而在男女生總體適能與語文成績(r=.227，p＜.01)、數學成績(r=.243，p＜.01)，皆達顯著相關，且強度達中度相關，研究結果顯示男女生在體適能表現好的，在學業成績也不差。

The purpose of this study is to know the physical fitness condition of the seventh grade students in one junior high school in Hsinchu, and to discuss the relationship between physical fitness scores and academic performance. The subjects of this study are 755 students, including 395 boys and 362 girls. The testing items are based on the norm of physical fitness issued by Ministry of Education, including body mass index (BMI), the sit-bending, the standing long jump, 1minute sit-up, and 800m or 1600m running. The testing grades will be changed into scores by the norm of physical fitness. The academic performance is the scores in the language filed and the mathematics filed in the first semester of 2011, and the collected data is analyzed by SPSS to discuss the relationship. The major findings of the study are as follows: 1.in BMI, 27% of boys are overweight, more than 17.4% of girls, 2.20.5% of girls are underweight, significantly more than 13% of boys. Schools and parents should pay more attention to whether the boys’ nutrition is over, and whether the girls’ is not enough. More than 60% of the students’ scores of four other fitness items-the sit-bending, the standing long jump, 1minute sit-ups, and 800m or 1600m running eached PR 25 based on the norm issued by Ministry of Education. The correlation of the physical fitness and academic performance is analyzed by Pearson correlation coefficient. The results are as followed: 1.the correlation of the boys’ physical fitness and the language scores (r=.161， p<.01), the correlation of the boys’ physical fitness and the mathematics scores (r=.198， p<.01). 2.the correlation of the girls’ physical fitness and the language scores (r=.154，p<.01), the correlation of the boys’ physical fitness and the mathematics scores (r=.107，p<.05). They are all significantly correlative. Especially, the correlation coefficient of the boys’ physical fitness and mathematics scores is the highest. The correlation of the boys’ and girls’ physical fitness and the language scores (r=.227， p<.01),and the correlation of the boys’ and girls’ physical fitness and the mathematics scores (r=.243， p<.01) are also significantly correlative. The result of this study is that the boys and the girls with good physical fitness do well in academic performance.
