摘　　要：针对目前大学高水平龙舟项目的训练特点,对龙舟陆上专项力量训练特征与划水效果的关系进行探讨,采用因子分析法提取陆上专项力量共性因子,建立划水功率和共性因子回归模型,结果:回归方程决定系数R=0.849,显著性概率P(Sig.=0.00)<0.01,表明回归方程与观察值之间的拟合优度很好,具有较好的实用性和操作性。因子回归模型为十四届全国龙舟锦标赛赛前训练控制和比赛成绩的预测提供训练理论依据。This paper explores the relationship between characters of special strength on land of dragon-boat and paddling power according to the top dragon-boat training traits in colleges. By the method of factor analysis, the authors pick the common factors of special strength, and build factor regression models of paddling power and common factors, The results show that regression formula coefficient R =0.894 and significance probability P （Sig. =0.00）〈0.01, which shows the fit is well between regression formula and observing value, and it is practical and operable. The factor regression model provides theoretical basis for forecasting competition results and the pre-ccrnpetition training control for the 14th National Dragon-boat Championships.
