场地自行车运动员在不同场地的骑行功率、阻力、速度和场地条件关系的探讨

Discussion on Relation among Power,Resistance, Velocity and Condition of Different Velodromes

研究自行车运动员在不同场地的骑行功率、阻力、速度及领骑尾随状态与场地条件之间的关系。用 5台德国产自行车数据收集分析系统 (SRM自行车仪 )收集 ,处理在南京、深圳、昆明、秦皇岛、香港、科罗拉多 (美国 )、卡里 (哥伦比亚 )等多个场地训练和比赛的生物力学数据后 ,按照不同场地和不同骑行状态计算在每个外在条件下运动员人车系统的阻力 ,并对其进行ANOVA分析。主要结论 :场地海拔和表面材质与骑行阻力有显著性关系。不论在什么场地骑行 ,领骑阻力与尾随阻力之间存在显著性差异 (P<0 .0 1)。在领骑时 ,阻力与速度有显著性关系(P<0 .0 1) ,而在尾随时阻力与速度没有表现出显著性关系。

This paper studies the relation among power output,resistance,veloci ty and position of rider at different velodromes.Five sets of Schoberer Rad Mes stechnik training system is installed into the bike of each subject.Data is col lected during training and competition from 7 different velodromes including Nan jing,Shenzhen,Kunming,Qinhuangdao,Hongkong,Colorado and Cali.The resistanc e of ride bike system on track is determined on different velodromes and positio ns of riders.ANOVA is employed to determine any significant different between d ifferent groups of data.The result shows that significant difference is found b etween altitude and riding resistance.There is significant difference in leadin g and following resistance at any velodrome.At leading position,there is signi ficant different between resistance and velocity,while at following position,t here is no significant different between resistance and velocity.
