Abstract
This article presents method of Nordic Walking gait data acquisition using motion capture. The author’s solution of markers location on human body is presented. It uses Davis protocol enhanced by additional markers for upper limbs and Nordic Walking poles measurement. The simplified kinematic computational model is presented. It was used for quality tests of data set generated during Nordic Walking gait. Problems with use of raw data are indicated. They cannot be used direct for kinematic analysis due to high noise in first and second signal derivatives. Sources of noise are presented and way to reduce them as well. Analysis of acceleration signals of measured data is performed. Butterworth filters with different cut off frequencies are used. The reconstruction of measured data from filtered and derivative signals is shown as well as comparison with original data.
