| 摘 要： | 对于速滑蹬冰足底力量分析与传导特征的研究,我们进行了国家优秀运动员和黑龙江省优秀运动员的采 样分析。为进一步挖掘实时反馈数据的应用价值,我们选取了一些分析指标:各区域力量输出消耗及其比率、力量 输出峰值及其与体重百分比、力量输出峰值延迟时间、单位时间内力量输出消耗、单步与复步波峰时间差及其与步 频的相关度等。对于足底压力反馈曲线的各个力学指标,从动力学角度进行分析,描述力学特征和力学意义,分析 力学特点与技术动作的关系,为寻找一种更先进和更省力的速滑技术提供科学依据。

| Abstract: | In order to study the plantar power from the push movement of speed skating and its conductive characteristics,the authors of this paper have carried on sample analysis on the national elite skaters and the elite skaters in Heilongjiang Province. Some analytical indicators including power output consumption in different areas and their rates,the percentage of the value of power output peak to weight,the delayed time of the value of power output peak,the power output consumption within the time unit,the time difference between the single-step wave peak and the multiple-step wave peak and their relativity with the step frequency, etc. have been selected so that the application values of instant feedback data can be further retrieved. Various indicators of kinetics from the feedback curve of plantar pressure are also analyzed from the point of view of kinetics to describe the kinetic characteristics and significance and the relationship between the kinetic characteristics and the skillful movements so as to provide the scientific foundations for a more advanced and efficient speed skating skill. |
