通过对我国优秀皮划艇运动员测试数据的分析,提出了基于桨频曲线转折点的皮划艇500m比赛竞速结构划分方法;根据全程桨频和船速的变化特点,对每个阶段重新命名,更准确地反映了皮划艇500m竞速规律;冲刺阶段桨频的增加并不一定意味着船速的提高,船速是否增长取决于平均桨力,它才是船速的最终决定因素;对世界大赛中分段成绩的进行对比分析;以我国划艇运动员杨文军参加世界大赛成绩为例,说明了竞赛策略的重要性。
通過對我國優秀皮劃艇運動員測試數據的分析,提齣瞭基于槳頻麯線轉摺點的皮劃艇500m比賽競速結構劃分方法;根據全程槳頻和船速的變化特點,對每箇階段重新命名,更準確地反映瞭皮劃艇500m競速規律;遲刺階段槳頻的增加併不一定意味著船速的提高,船速是否增長取決于平均槳力,它纔是船速的最終決定因素;對世界大賽中分段成績的進行對比分析;以我國劃艇運動員楊文軍參加世界大賽成績為例,說明瞭競賽策略的重要性。

Through making analysis on testing data of Chinese elite male canoeist, this paper put forwards that the turning points of oar frequency curve are exactly the boundaries of competitive velocity structure. Based on the changing characters of oar frequency and boat velocity, the competitive velocity structure is re-divided and every stage is given a new name. At the final phase, the boat velocity is not always increasing along with the oar frequency. The average oar force is the determining factor of boat velocity. The analysis on result of every stage suggested the correct strategy. The importance of competitive strategy is illustrated with the results of YANG Wen-jun at major world's game.
