| Summary: | 碩士 === 國立臺灣體育運動大學 === 體育研究所 === 100 === 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.
