서울 Olympic 砲丸던지기 決勝에 參加한 選手들의 運動學的 要因에 의한 技術分析 = Analysis of Techniques by Kinematic Factor in a Final Game of Shot Putting Thrower at the Seoul Olympics

다국어 초록 (Multilingual Abstract)

The subjects were used 7 shot put throwers of Track & Field final game in Seoul Olympics. The Kinematic analysis of three phases were performed from the data obtained through cinematographic method (64frame/sec) The results were as follows;
Ⅰ. Gliding Phase.
1. Gliding distance of Oltmpic's shot put throwers was the average 47.5% of height.
2. The average vertical movememt distance of C.G. was 5.33∼23.47cm, total average was 15.20cm.
3. The average gliding time was 0.1563∼0.2907sec.
4. The average landing spot and C.G. of angle was 45.9∼55.8°.
5. The average horizontal distance between hill of left foot and Toe-board was 8.52∼29.65cm. I think there needs training for well using circle.
Ⅱ. Throwing Phase
1. The average distance of throwing was 94.27∼122.24cm and total average 55.28% of height.
2. The average after landing of gliding foot and landing time of left foot was 0.0156∼0.1092sec. The horizontal distance of C.G. was 29.77∼39.20cm.
Ⅲ. Releasing Phase
1. The average throw height was 205.78∼220.96cm. It was higer than our country's thrower.
2. The average of initial velocity of the throw shot put was 10.68∼16.45m/sec.
It showed that initial velocity was high.
3. The average throwing angle was 36.3-42.3° Itwas no stability than ideal angle 42°. 4. The average distance between shot put and Toe-board was 9.15∼24.69cm.
