| Summary: | 碩士 === 輔仁大學 === 體育學系碩士班 === 97 === The purpose of the study is to explore the grenade score which was influenced on the angle of release, the velocity and angle of joints, and the velocity of grenade when the grenade was released in the moment. Masculine and feminine receiving training student from the specialized reserve officer class in Army Infantry School were selected as research participants for analyses. Kwon3D motion analysis system was used to analyze and obtain sport parameters. SPSS 12.0 for Windows were applied for statistical analyses. The descriptive statistics method and Pearson´s product correlation were carried out to analyze parameters of Kinematics. Results are as follows:
1. The velocity of right wrist joints(r=0.996), the angle of right elbow joints(r=0.883), the angle of left shoulder joints(r=-0.989), and the angle of left elbow joints(r=-0.838) as well as the distance of release reached the significant level. The velocity of right wrist joints of masculine and feminine should be 10.26±0.12 and 8.79±0.13m/s. The angle of right elbow joints of masculine and feminine should be 170.76±3.34 and 163.06±2.29 degree. The angle of left shoulder joints of masculine and feminine should be 112.92±4.62 and 134.24±1.19 degree. The angle of left elbow joints of masculine and feminine should be 93.88±5.28 and 135.85±22.68 degree.
2. The velocity of right hip joints(r=0.964), the velocity of left hip joints(r=0.990), the velocity of left knee joints(r=0.873), and the angle of left knee joints(r=-0.950) as well as the distance of release reached the significant level. The velocity of right hip joints of masculine and feminine should be 1.61±0.13 and 0.58±0.19 m/s. The velocity of left hip joints of masculine and feminine should be 1.57±0.13 and 0.69±0.03 m/s. The velocity of left knee joints of masculine and feminine should be 1.95±0.23 and 1.23±0.26 m/s. The angle of left knee joints of masculine and feminine should be 156.48±3.59, and 175.13±3.10 degree.
3. The angle of release (r=0.983) and the velocity of grenade (r=0.998) in the moment as well as the distance of release reached the significant level. The angle of release in the moment of masculine and feminine should be 54.91±1.63 and 42.62±1.87 degree. The velocity of grenade in the moment of masculine and feminine should be 18.55±0.66 and 10.52±0.37 m/s.
