By using the two-dimensional motion system,this paper analyses the technique indexes of oar frequency,oar power and oar distance,and explores the characteristics of canoeing.
通过二维摄像解析优秀男子划艇运动员500m划过程中桨频、单桨桨力以及桨幅等动力学指标,研究运动员全程划技术特点和体能特点,研究结果表明:500m划过程中,桨频、单桨桨力以及艇速的变化基本一致,表现出起航时高桨频,中途由高桨幅代替桨频维持艇速,而在冲刺阶段是以高桨频和高桨幅维持冲刺效果的特征。
