中文摘要 | 本研究係採用以文獻探討的方式,將影響短距離起跑中有關生物力學(運動學與動因學)常用研究主題的參數作一比較研究,並作有系統化整理,予以歸納出研究結果,提供教練與研究人員作為日後研究方向的參考與建議。經文獻的整理與討論得知,影響短距離起跑的生物力學表現如下: 一、起跑架相關位置與短距離起跑之表現而言,發現到短式起跑法(bunch start)在重心接近起跑線、反應時間上較有利;中式起跑法(medium start)在身體平衡狀態較有利;長跑起跑法(elongated start)則在雙腳推蹬力及身體放鬆狀態較有利。 二、受SSC之機轉影響,對短距離起跑推蹬階段的肌肉群而言,以股直肌、比目魚肌及霏腸肌影響最鉅。 三、 短距離起跑推蹬階段之前、後腳膝關節角度應為90∼110度及130∼140度;且關節傾斜角度與體型無關。 四、短距離起跑推蹬階段之身體重量分配到雙手之比例小於50%;且身體心位置至地面高度平均為60∼66公分。 五、世界一流的短距離選手,後腳的推蹬力量比前腳推蹬力量來的大;但垂直方向的推蹬總衡量則前腳比後腳大。 |
英文摘要 | The purpose of this study was to analyze the biomechanic's parameters of sprint start. The subject of the research adopted content analysis and the parameters of the influenced the sprint start were compared, and do systematic inductiveness in the data. The result was of importance not only in understanding the characteristics of the athlete, but also in providing references and suggestions to coaches and researchers in their future research. The findings are as follows: 1.In the block positioning and sprint start performance, the bunch start advantaged with both C.G near start line and reaction time. 2.The muscle's group contributed to soleus, rectus femoris, and gastrocnemius with respect to the block phase of sprint start in the SSC. 3.The block phase of the sprint start was 90~110 degrees and 130~140 degrees in knee's degree of the interposter-foot. 4.The body weight distributed to tow-hands in proportion was less than 50%, and the average distance was 66~66cm from total body center of gravity position to ground. 5.On the elite world sprinter, rear foot was larger than front foot in the block force, but rear foot was smaller than front foot in the vertical impulse. |
