國內外百公尺跑速度之比較分析

本研究是以參加2004年國際田徑邀請賽我國百公尺女子組、男子組決賽前六名選手作為研究對象。本研究的目的為探討園內外優秀百公尺跑步福、步頻技術指標加以比較分析，找出影響我國選手成績表現的重要因素，以提供給教練及選手作為訓練時的參考。本研究結果：一、我國女選手與中國全運會選手作比較，其步幅均值差距較小，步頻均值差距較大；與奧運會選手作比較，則是步幅均值差距較大，步頻均值差距較小。二、我國男選手與奧運會選手作比較，主要為步輻能力的差距；其成績落後的原因為步輻能力不足。百公尺全程步數多，是造成步幅偏短的原因。三、我國男選手步輯和步頻發展不平衡，欲突破成績表現，應大致保持步頻指數不變，將步輻指數提高，是目前訓練工作所要重視的課題。

This study considers the 100-meter male and female groups' finals from the one who gets from the first place to the sixth place as researched fellows in the international track and field meet in 2004. The purpose of this study is to research the domestic and overseas outstanding 100-meter runners' length and frequency per step technique and also to find out the important factors which have influence on the selected contestants' scores and then to offer a reference to coaches as well as trainees. The survey shows: First, taking the female contestants with China female runners to compare. The gap average between their step length is shorter than the gap average between their step frequency. Second, the domestic female contestants' average of both the overseas excellent selected contestants can get the upper hand in their step length ability in an international stage. Third, taking the domestic male selected contestants and the Olympic games contestants to compare, the major difference in their backward score is the deficient of step length. Fourth, despite the domestic male contestants' unbalanced step length and step frequency, they still break their records. At present, we should emphasize the pre-training work to reduce footsteps, to extend step frequencies, and to find out the perfect match of the step length and the step frequency.
