摘　　要：运用测试、数理统计等方法,完成了对我国优秀男子赛艇运动员（13名）3种不同桨频（20桨/min,26桨/min和34桨/min）下的技术动作的数据采集与分析,并与国外优秀男子赛艇运动员的数据进行对比,结果显示：1）国内外赛艇运动员不同桨频下的划距和相对划距曲线变化特征相似,在同一桨频下无显著差异（P〉0.05）,但在数值上优于国内运动员;2）国内外运动员的力值变化并不一致,国外优秀运动员的最大下肢力量并不一定随着桨频的增加而增加,而国内运动员呈递增特征,且在不同的桨频下,两者的最大桨柄拉力值存在显著性差异（P〈0.05）;3）国内外运动员之间的划船轨迹重复性相对稳定（RP值范围0.038-0.057）,两者之间无显著性差异存在,但国内运动员随着桨频的增加重复性系数有增大趋势,且表现出一定的技术不稳定性。结论：建议我国运动员在划距与桨频的搭配中,应注重划距的获得,同时,加强不同桨频下的技术稳定性和改进躯干的后仰角度。The use of test,mathematical statistic method to complete data collection and analysis of the rowers （13） at three different stroke rates （20 stroke/min ,26stoke/min ,34stroke/min）, and compared with the foreign elites, the results show that 1 ） stroke length and relative stroke length of different levels rowers have similar curve characteristics under dif- ferent stroke rafes, there was no significant difference in the same stroke rate （ P 〉 0.05 ）, but value of the stroke length is more longer than chinese elite athletes;2） the force of China and foreign athletes is inconsistent, the maximum leg strength does not necessarily increase with the stroke rates increasing for foreign elite athletes, while the china athletes was increased at different stroke rates, and there was a significant difference between the different level athletes （ P 〉 0.05 ） ;3 ） trajectory repeatability is relative stability between athletes of china and foreign and china athletes （ RP range 0.038 - 0.057 ）, no sig- nificant difference exists between the two ,but the trajectory repeatability of china athletes show some instability with stroke rates increasing. Conclusions： Suggested that our athletes in the stroke length and with plasma frequency, should be excel- lent on stroke distance is obtained, at the same time, it should to strengthen technical stability of different plasma frequency and adjusted trunk angles.
