Abstract

This study evaluated the influence of sliding of surface on GRF for 15 normal subjects. They have walked on a surface by two force plates in two different states: dry and sliding. The data were analyzed in frequency range instead of time range by utilizing Fast Fourier Transformation (FFT) and in each frequency, the amplitude of tangential forces were investigated in voluntarily and reflexive
motion ranges of frequencies of human movements. Figures of summation of all tangential forces resultant revealed that the amount of amplitude of GRF and slope of changes in dry surfaces is more than sliding surfaces in heel-strike and toe-off phases. Moreover, force vibration in dry surfaces is more considerable than sliding surfaces and it was more significant in heel-strike than toe-off. It was concluded that the dry surfaces are not completely safe and the impact that is imposed by ground in dry surface especially in heel-strike phase is high.
