本研究之目的在探討體能課程介入教學前與教學後軍校生體能與手榴彈投擲 成績表現差異情形。本研究是以國防大學96 學年度二年級286 名軍校生為研究對 象。研究對象採立意取樣分成控制組及實驗組，整體平均年齡為19.72 歲。教學 期程為每週實施一次、每次一小時教學，為期九週教學實驗。並於教學前與教學 後分別實施仰臥起坐、引體向上及3000 公尺跑步等三項體能及手榴彈投擲測驗。 將測驗所得數據經整理以SPSS（10.0 中文版）統計程式進行分析後，獲得以下研 究結果：（一）教學後，實驗組及控制組組內之軍校生在三項體能及手榴彈投擲技 能之成績表現均優於教學前；兩組內手榴彈投擲技能成績表現均未呈現顯著差 異。（二）教學後，兩組間之軍校生在三項體能成績表現呈現顯著差異；且實驗組 在體能成績表現顯著優於控制組。（三）教學前與教學後三項體能與手榴彈投擲技 能間成績表現則未呈現顯著相關。綜合以上結果本研究結論為：軍校生經九週體 育教學後，在仰臥起坐、引體向上及3000 公尺跑步等三項體能之成績表現呈現顯 著的提昇，且三項體能之間呈現顯著正向影響。研究同時發現軍校生在戰技手榴 彈投擲成績表現，未隨著仰臥起坐、引體向上及3000 公尺跑步等三項體能成績表 現的進步而獲得提昇。

ABSTRACT This study analyzed the cadets physical fitness course intervene teaching front with teaching behind cadets physical fitness with grenade throw score of performance difference situation. Participants of this research are 286 male cadets of National Defense University. Researches object pick up conception sampling divided into control group and experience group two group of, whole average age for 19.72 year olds. Teachings for every week practice once, one hour teaching each time every week, last nine weeks the teaching experiment. With teaching behind and teaching front practice sit-up, pull-up and 3000 meters run of physical fitness and grenade throw test。Will test earning data by neaten as SPSS (10.0 Chinese editions) stats procedure proceed analyzed, the results showed that, (1) teaching behind, experiences group and control group in cadets generate throw score of performance superior to teaching front ; two groups of in grenade throw score of performance have not conspicuously difference, (2) teaching behind, two groups of between take on conspicuous difference at cadets physical fitness, and experience group behave conspicuous superior to control group at physical fitness, (3) teachings front with physical fitness and grenade throw score of performance not take on conspicuous relative behind teaching。this research conclusion for: Cadets by nine weeks the teaching, at sit-up, pull-up and 3000 meters run three physical fitness score of performance take on conspicuous promotion, and take on conspicuous to affection three physical fitness between。Researches meanwhile discover cadets at military skill of grenade throw score of performance, not along with sit-up, pull-up and 3000 meters run three physical fitness score of performance make progress but acquire promotion.
