    In the absence of visual information, humans cannot maintain a straight walking path. We examined the hypothesis that step frequency during walking affects the magnitude of veering in healthy adults. Subject walked at a preferred (1.77 ± 0.18. Hz), low (0.8 × preferred, 1.41 ± 0.15. Hz), and high (1.2× preferred, 2.13 ± 0.20. Hz) step frequency with and without a blindfold. We compared the absolute differences between estimated and measured points of crossing a target line after 16. m of forward walking at the three step frequencies. There was no significant difference in veering when subjects walked at the different frequencies without a blindfold. However, the magnitude of veering was the smallest at the preferred (mean ± SE = 91.6 ± 33.6. cm) compared with the low (204.3 ± 43.0. cm) and high (112.7 ± 34.0. cm) frequency gaits with a blindfold. Thus, walking at a preferred step frequency minimizes veering, which occurs in the absence of visual information. This phenomenon may be associated with the previously reported minimization of movement variability, energy cost, and attentional demand while walking at a preferred step frequency.
