目的：探討少年學童學習射擊運動之後，其對課堂學習的專注力是否有差異性。
　　方法：以44位國小四年級自願參加之健康受試者，區分為射擊隊：9.4±.51歲，羽球隊：9.08±.28歲，控制組：9.33±.62歲，於八周期間進行射擊、心跳率及專注力的前測與後測。射擊採用的是奧運項目中所規範的空氣手步、槍及鉛彈進行立姿有依托十公尺射擊，判定10發彈著成績；心跳率測試以POLAR心跳監測器進行安靜時及射擊時心跳率的測試，以心率減速做為依據；專注力則是以E-PRIME專注力測試軟體的反應時間進行測試，並輔以問卷調查內容後，以評分的方式分析前後測差異性；而諸多變因所得結果與課業進行分析，是否有其相關性。所得資料以SPSS 10.0中文版就相依樣本t檢定與皮爾遜積差相關法等統計方法進行分析，顯著水準定為p<.05。
　　結論：
壹、射擊隊經系統且質量並重的射擊訓練之後，成績明顯進步，而進步原因與心跳率降低以及擊發前心跳減速有明顯關係。
貳、因心跳率降低，瞄準軌跡會更加穩定、規律，致使射擊隊射擊成績有所進展，此成長原因應來自於生、心理互為穩定的因素所造成，然而其餘兩組則未見有明顯差異。
叁、就專注力的表現而言，由於射擊隊經射擊運動訓練後所習得的專注技能（注意力控制、分配、專注），在不自覺當中即會運用於其測試當中，因而使得專注力的反應時間也呈現出顯著差異性，而其餘兩組則未見專注力反應時間有顯著差異。
肆、就射擊隊而言，因射擊運動訓練介入後，射擊成績的進步與問卷的得分表現及課業成績表現有顯著相關。

Research Objectives:
This thesis mainly contributes to explore if there is a statistical significant difference of concentration in class of teenager after they finished shooting practices.

Research Method:
This thesis selected three divisions of 44 healthy volunteers from an elementary school. The mean age of shooting team is 9.4±.51 years old, the badminton team is 9.08±.28 and the control group is 9.33±.62. Selected students made several referenced exams, which included pre- and post-test, such as shooting, physiological situation (ex. Heart rate) and their concentration index during a period of 8 weeks.
This thesis employed air pistols and air rifle, which are certified and regulated by Olympics Game, to practice a 10-meters standing shooting. Each student has 10 opportunities to reach their best scores. Also, this thesis tested the reduction of heart rate in different situations including silence and shooting environments by POLAR monitors. Concentration of students is tested to get the reaction time by E-PRIME software system. Specified questionnaire is also employed as a subsidiary tool to understand the difference between pre- and post-shooting practices.
Finally, this thesis analyzed the relationship between class grades and measurements by Pearson’s coefficient of correlation and T-test. The analytical results contribute to out knowledge that there is a statistically significant difference between pre- and post-shooting practices under a confidential level as p-value<.05

Conclusion:
1. The grade has a statistically significant advancement of members in shooting team. This obvious advancement of shooting performance mainly related to that our systematic practice lowered heart ratio before their shooting.
2. It has been proven that shooting trajectories will be much more stable and regular due to reduction of heart rate of shooter. This reveals that a stable physiological and psychology situation of shooter could enhance the performance of the shooting team.
3. The reaction time (as an index of concentration of students in this thesis) has a statistically significant reduction due to the enhancement of concentration, allocation and control from shooting practice.
4. The grades of volunteers in the shooting team had a statistically significant advance positive to shooting performance and scoring after this thesis practices a shooting exercises.
