| 摘 要： | 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。但是运动员在途中划阶段,由于耐酸能力的下降,导致抓水不牢、晃桨的现象。

| Abstract: | 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.The results show that in the 500m canoeing,the change of oar frequency is consistent with oar power.The elite keep the velocity by increasing oar frequency at the starting moment,lower the oar frequency,increasing the oar power at the middle moment,and at the result moment,the excellent achievement is keeping high oar frequency and oar power.Furthermore,the effect of oar power is not good because that the blood lactate declines at the middle moment. |
