| 中文摘要 | 本研究主要目的,在於推估當前男子世界標槍紀錄保持者(1998)之最佳出手條件。研究方法是引用Terauds新規則標槍之攻角及壓力中心關係圖資料(詳見Bartlett & Best, 1988, p.5),運用數值方法進行推估。結果發現無風時,世界紀錄保持者若以投擲角32.25°,最佳體角34.5°,攻角為-0.75°時,最小的出手速率只要31.906m/s,就能達到世界紀錄94.48m,如果風速率在-5m/s到3/s的範圍內,順風時投擲成績並無明顯的改變,但逆風時投擲成績卻明顯下降現象。 |
| 英文摘要 | The purpose of the study was to simulate the optimal release conditions of current male holder of javelin world record. The methodology was the use of numerical methods acting on the information on the center of pressure variation with angle of attack in Terauds’ New Rules Javelin (Bnartlett & Best, 1988, p.5). The results showed that under the no-wind condition, the male holder could reached the world record of 98.48m with the minimal release speed of 31.906 m/s as well the release angle of 32.25°, the attitude angle of 34.5°, and the attack angle of -0.75°. If the wind speed fell within the range between -5m/s and 3m/s, no significant variation in performance arised in the tail wind. But in the head wind, the throwing distance was diminished. |
