Abstract: In view of the existing human body velocity of movement models insufficiency, it was mainly studied which characteristic parameter of acceleration information and the gait change rule can reflect the velocity of movement under the different speed pattern. 20 young masculine volunteers were recruited, the characteristic parameters which including the maximum value, the minimum value, the rootmeansquare, the valley value, step frequency, the support time and the duration of oscillation were obtained while walking speed at 3 km/h, 4 km/h, 5 km/h, the 6 km/h in jogs machine on walks. The experimental result indicates that the step frequency, the rootmeansquare, the valley value can estimate the walking speeds in realtime, after the integration analysis of correlation coefficient, operability and the coefficient of variation of every parameter. All of conclusion can offer basic theoretical support for the development of pedometer and the instrument of specific power consumption.
