摘要

競速滑輪是2001年世界運動會中，中華代表隊獲得獎牌數最多的項目；而2006年競速滑輪在亞洲盃中，台灣地區也囊括了300公尺亞錦賽的男、女金牌。因為競速滑輪的運動人口已經達到一定的數量，2010年亞運會已確定將「競速滑輪」納入競賽項目之中。台灣地區在此單項成績優異，而其中又以短距離300公尺項目最為傑出，因此本研究目的為探討選手於起跑加速階段，採不同步數的起跑(原習慣步數±2步)方式，其步頻、步幅、最短起速時間之差異。
本研究以七名北縣市前三名競速滑輪選手為受試對象。受試者須完成三種不同步數的起跑方式，以三台JVC 9800高速攝影機（120Hz）進行二度空間之拍攝，經由Kwon3D影像分析軟體進行處理，將得到參數資料以SPSS 13.0版統計軟體進行統計分析，以單因子變異數分析來檢定相同受試者接受三種不同跑法之差異顯著性，統計水準定為α＝.05；此外在不同受試者間，依瞬間速度、時間、步頻、步幅的個別差異採用描述性統計
本研究主要結論為：一、在起跑時，跑的步數增加時，受試者的表現較佳。二、以擴大的步幅的方式起跑可能可以增進表現，步頻的影響則無定論。三、肌力的平衡為競速滑輪選手所應加強的訓練。四、起跑者由跑轉滑的原因並非因為速度到達極限，未來可在短程中要求受試者全程以跑的方式來實驗。

Speed roller skating, in World Game 2001, were the events that team of Chinese Taipei win most medals. In Asian Cup,2006, our speed roller skating team also won both man and woman 300-meter-group gold medals. Speed roller skating had become an event in Asian Game, 2010 due to more and more people enjoyed it. We played well in speed roller skating, especially 300-meter competition. However, there was no many researches focused on the skill. The purpose of this research is to find the difference and correlation between stride, pace frequency and speed in the getout under different pace amounts (usual practice ± 2 paces).
Objects are seven young top skater in Taipei. They have to complete the getout by three different pace amounts. The course was filmed by three JVC 9800U camera (120Hz) in two dimension. The data collected is analyzed by Kwon3D software and SPSS 10.0. One-way ANOVA was adopted to analyze the difference in the three getout of the objects.( α＝.05). Descriptive statistics was adopted as to the difference between velocity, time, pace frequency, and stride in our objects.
Conclusion showed that: first, better performance was noted as the pace amounts increase. Besides, bigger stride brought better performance though the correlation between velocity and pace frequency was controversial. It’s important for our objects to improve their muscular power balance. Finally, the reason of why all skaters turned run to glide in competition is not related to the speed and further research is needed.
