本研究主要目的在探討國小高年級學童獎勵制度在體適能對學業成就之干擾影響。本研究以桃園縣某國小高年級學童為研究對象，進行體適能檢測，並分析其 7大學習領域之學業成就，參與研究樣本計有 432位學童，所得之資料以 SPSS 19版之統計套裝軟體為工具，進行描述性統計、階層迴歸分析後得到結論：為心肺能力愈好的學童，且有獲得體適能獎章的學童，在語文成就、數學成就、學業成就的表現就愈好。故可從增強學童的心肺能力方面能力，同時提高學童獲得體適能獎章的能力，如此便能有效提升學童的語文成就、數學成就與學業成就的表現。本研究根據結論及建議，希冀提供教育單位、學校及教學教師的參考，並給未來研究者參考。

This research was purposed to explore the interference on academic achievement wielded by physical fitness in view of the reward system among the 5th and 6th graders of elementary schools.

There were totally 432 students joining to serve as research samples. All the data obtained were analyzed by the Statistical Software SPSS 19 and conducted by means of descriptive statistics and hierarchical regression analyses with results conducted as below. Students advantaged with excellent cardiopulmonary capacity and rewarded with excellent physical fitness performed better in the academic achievement of mathematics and languages. Therefore, it was available to improve students’ cardiopulmonary capacity simultaneously with the capacity to win the rewards due to excellent physical fitness well enhanced. As such, it was feasible to effectively improve students’ academic achievement in languages and mathematics. In this research, based on conclusions and suggestions, it was hoped the reference for upcoming research effort could be available for educational sectors, schools and teachers.
