本研究目的在了解民德國中一年級學生的體適能情況，並和教育部體育署之體適能常模進行比較，將結果作為學校體育教學或政策施行之參考。以民德國中以110學年度一年級學生為研究對象，共有654名(男學生344人，女學生310人)，研究相關變項為坐姿體前彎、身體質量指數、一分鐘仰臥起坐、立定跳遠、1600M(男生)、800M(女生)，測驗相關數據以excel及SPSS統計軟體進行敘述性分析，研究結果發現，民德國中13歲-14歲男女學生的身體質量指數都為正常範圍；男學生的跑走及立定跳遠都為銅牌，女生都為銀牌；男女學生的一分鐘屈膝仰臥起坐都為銅牌；13歲男學生的坐姿體前彎為銅牌，14歲男學生為中等，13歲-14歲女學生都為銀牌。結論：民德國中14歲男學生的坐姿體前彎方面表現較為不理想，未來體育教學及相關活動計畫應加強這些學生腿前、腿後、小腿、腰部的課程練習，並依據個人身體情況及肌肉型式進行練習。
