摘要
对赛艇划桨过程中回桨阶段出现第二个加速度峰值的动力源进行了分析 ,提出运动员在回桨过程中 ,人体重心从船头向船尾移动产生冲力 ,从而使船艇加速。并据此提出了包括拉桨动力和人体重心移动产生冲力两个动力源的赛艇动力学方程。此外 ,对提高赛艇技术的途径和赛艇桨叶及船艇的流体动力性能和快速性能进行了分析和论述 。
This article studies the power origin of the second accelerating peak during the recovery stage of oaring.During the process,the move of center of gravity fore and aft generates power and thus speeds up the canoe.Based on this,two canoeing dynamic formula of pulling and shifting of gravity were put forward.It also analyzes methods to better canoeing techniques and blades. Canoeing dynamics and hydrodynamic performance and mobility were further synthesized so as to provide scientific basis for promoting canoeing training.
