【摘要】 利用动力学模型,研究皮艇运动员划桨功率指标与专项成绩的关系,并探讨其在训练实践中的应用途径。发现:1发展运动员划桨周期中的平均功率是提高单人皮艇1 000 m成绩的关键,1 000 m专项成绩和平均功率之间是非线性关系,运动员体重和风向、风力对专项成绩也有一定的影响;2以划桨功率指标与专项成绩的关系为基础,等功率校正方法可用于不同风向、风力下的成绩比较和训练水平检验;3利用划桨功率指标与专项成绩的关系可打造不同成绩水平下的运动员个体能力目标,并和皮艇测功仪做功指标进行比较可以反映现实体能差距;4由划桨功率指标与专项成绩的关系可以明确运动员体重和功率指标变化的适配准则,为形态体格的专项适应性改造提供依据。更多还原

【Abstract】 The study elaborates the relations betw een paddling pow er and specific performance of kayakers on the basis of dynamic model,and the application in training is also explored.The findings show that: 1 The development in average pow er w ithin a stroke period is the key factor to elevate kayakers ’performance in 1 000 m,and the relationship betw een average pow er and specific performance show s nonlinear features; the kayakers’ body mass and w ind force have a definite influence on the performance. 2The methods w ith equal pow er correction may be applied in the performance comparison and training state testing. 3 On different performance levels,it may establish the training target in specific w ork capacities w hich may be used to compare w ith the pow er index of ergometer to reflect the realistic gap in individual physical pow er for kayakers. 4 The adaptation principle for concurrent variation of kayakers ’ body mass and specific w ork capacities is firmed in order to provide the reference for the specific reformation of the kayakers’ physiques.更多还原
