本文作者对足接触时间方式进行分析,以便对其与步行速度及年龄的影响关系进行测定。同是,对迈步时间的正常次数与身高的正常速度之间的关系的影响也进行了测定。该研究用了47名4～39岁受试者的272种足接触方式。数据组中包括足接触时间的开始与结束和步行速度。作者利用最小的均方差标准建立了两个数学模型,用于实际次数的指数模型和用于正常次数的线性模型。作者展示了用F比率标准进行的一项统计试验,并用此对不同年龄组的特性回归进行了比较。试验测定出模型回归是否类似或符合。研究结果表明,迈步时间正常对减小年龄差别最为有效。在实验中观察到这样一种趋势,它不同于早先研究人员的观点:4岁形成成熟步态。回归比较表明,所有年龄都相似,但儿童
The authors analyzed the foot contact time pattern to determine its impact on walking speed and age. In the same way, the effect on the relationship between the normal number of steps and the normal speed of height was also determined. The study used 272 foot-in-touch pairs of 47 4- to 39-year-old subjects. The data set includes the start and end of foot contact time and walking speed. The authors established two mathematical models using the smallest mean-square-deviation criteria, an exponential model for actual times, and a linear model for normal times. The authors present a statistical test using the F-ratio standard and use this to compare the regression of different age groups. The test determines whether model regression is similar or consistent. The results show that normal walking time is most effective in reducing the age difference. In the experiment observed a trend that is different from the previous researchers point of view: 4-year-old to form a mature gait. Regression comparison shows that all ages are similar, but children
