AB  - The aim of this study was to investigate the effect of flooring on barefoot gait 
      according to age and gender. Two groups of healthy subjects were analyzed: the 
      elderly adult group (EA; 10 healthy subjects) and the middle-aged group (MA; 10 
      healthy subjects). Each participant was asked to walk at his or her preferred 
      speed over two force plates on the following surfaces: 1) homogeneous vinyl 
      (HOV), 2) carpet, 3) heterogeneous vinyl (HTV) and 4) mixed (in which the first 
      half of the pathway was covered by HOV and the second by HTV). Two force plates 
      (Kistler 9286BA) embedded in the data collection room floor measured the ground 
      reaction forces and friction. The required coefficient of friction (RCOF) was 
      analyzed. For the statistical analysis, a linear mixed-effects model for repeated 
      measures was performed. During barefoot gait, there were differences in the RCOF 
      among the flooring types during the heel contact and toe-off phases. Due to 
      better plantar proprioception during barefoot gait, the EA and MA subjects were 
      able to distinguish differences among the flooring types. Moreover, when the EA 
      were compared with the MA subjects, differences could be observed in the RCOF 
      during the toe-off phase, and gender differences in the RCOF could also be 
      observed during the heel contact phase in barefoot gait.
