本研究目的在暸解超級馬拉松24小時賽國外優秀女跑者稻垣壽美惠（Sumie Inagak），與國內優秀女跑者邱淑蓉的成績、步頻、步幅的分析比較。透過錄影拍攝24小時參賽過程中每小時跑者的步頻與步幅的資料，並以動作分析軟體（Kwon3D）整理所得空間與時間參數資料做為整理，依跑者的個人資料及成績以SPSS 12.0及Microsoft Excel進行資料分析。本研究所得如下：一、國外與國內超馬跑者的平均速度皆隨著時間增長而速度變慢。二、國外跑者與國內超馬跑者的步頻並無顯著差異。三、國外與國內超馬跑者的步幅有明顯差異，並影響跑者成績表現。

The purpose of this study is to compare the differences of the speed, frequency and length of strides of an elite Japanese runner, Sumie Inagak, and the Taiwanese runner, Shu-Jung Chiu, in Soochow University Ultra Marathon 24hr Race. We video-record the two runners throughout 24 hours in the competition and used a comprehensive motion analysis software, Kwon3D, with the time and spatial (3D) parameters to collect stride frequency and stride length hourly. The statistical analyses were analyzed by SPSS 12.0 and Microsoft Excel. We found that both runners reduced their running speed significantly while the time increased. No significant difference of the stride frequency has been found between two runners. However, the Japanese runner has greater stride length than the Taiwanese runner and this difference might influence their running performance.
