摘　　要：以艇速作为标准,采用系统分类与判别分析方法将赛艇各单项进行分层,对各层次中世界优秀运动员桨频与划距的关系进行相关分析与线性回归,并且探索了其对艇速的影响。研究表明,在各层次单项群内优秀运动员桨频与划距均存在高度负相关;桨频每分钟增加1桨,划距(按艇速层次从下到上)分别减少0.160m、0.217m、0.189m、0.154m和0.265m;反之亦然。在各层次单项群中艇速随着桨频变化成倒"U"形变化,在自变量范围内各层次单项群间艇速的变化存在差异。研究认为,各层次单项群的优秀运动员中桨频与划距存在高度负相关关系,这两个变量在一定范围内变化能够提高艇速,并且存在最佳值,使艇速达到最大。建议应用不同层次单项群桨频与划距、桨频与艇速的回归方程诊断优秀赛艇运动员划桨技术,利用理想的桨频与划距搭配改进划桨技术训练。Using the boat velocity as standard, the essay stratifiy the individual events of rowing by methods of hierarchical cluster analysis and discriminant analysis, and the relationship among boat velocity, stroke rate and distance per stroke has been studied through bivariate correlations and linear regression. The main results are the following ： 1 ） stroke rate is highly neg- ative correlative with distance per stroke in elites, in each level, and with stroke rate increased 1 stroke per minute the distance per stroke is cut down by 0. 160m （lower level）, 0. 217m （ lower-middle level）, 0.189 m （ middle level）, 0.154m （ upper-middle level）, 0.265 m （ upper level）. 2） the variety of boat velocity is like shape of reversed ＂U＂ with stroke rate or distance per stroke changed in each level, but has some differences among each level in the range of independent variable. The main conclusion is that the more stroke rate or distance per stroke in each level, the less distance per stroke or stroke rate accordingly, but the boat velocity is improved by it decreased according to certain ratio in certain range. It suggests that using the equations of stroke rate and distance per stroke and curve of boat velocity for technique diagnoses and training improvement.
