Frequency Characteristics of Race Walking Motion Focusing on Acceleration of Body Parts in the Forward and Backward Direction

The purpose of this study is to represent race walking motion in the frequency domain and to elucidate periodic characteristics of race walking motion in the frequency domain. Using power walking as a comparison for race walking, we will examine the changes in the characteristics observed in acceleration of 15 body parts when the pace is varied from 120 to 200 BPM in 10 BPM increments. In the previous report, vertical acceleration was observed. In this report, the characteristics of motion are elucidated using forward and backward acceleration. The analysis revealed that lower leg characteristics differed between race walking and power walking. This result indicates that the leg is the part in which athletes perform the motions required to comply with the rules of race walking.
