优秀赛艇运动员测功仪2000m模拟比赛供能特征研究

Research on Energy Supply of Excellent Rowers Simulating Match(2 000m)with Ergometer

研究的目的在于运用测功仪模拟赛艇2 000m比赛,以探究赛艇项目比赛过程中的供能特征。10名某省优秀赛艇运动员(男6女4)自愿参加赛艇测功仪6.5min的全力划。运用便携式气体代谢仪(CosMed,K4b2)所测得的摄氧量数据和血乳酸分析仪(Diagnostic C-line,EKF)所测得的血乳酸数据进行能量供应量的计算。结果表明,赛艇项目2 000m三大供能系统的比例分别为6.2%(无氧无乳酸)、10.1%(无氧乳酸)、83.7%(有氧)。研究结果与前人研究相似,并进一步明确了有氧供能对于赛艇比赛的重要性。三大供能系统比例的确定为教练员安排训练负荷和评价运动员的运动能力提供了理论依据。

The purpose of this research is to simulate match（2000m）with ergometer and make a thorough inquiry into the characteristic of energy supply of rowing during competition.10 excellent rowers（6male,4female）all are first grade athletes）who are volunteers take part in all-out rowing（6.5min）with ergometer.Uses Portable gas metabolism instrument（CosMed,K4b2）and blood lactate to analyze instrument to calculate the measurement of energy supply.According to the result,the three energy supply system ratio of rowing special distance（2000m）is phosphoric acid（6.2%）,anaerobic lactic（10.1%）,aerobic（83.7%）.Research finding is similar with previous research and emphasize the importance of aerobic capacity for rowing.So it is very important for us to know the proportional relation between three energy supply systems in order to provide momentous theory evidence which can lead training scientifically.
