Step rates on the oiled plate. (A) Histogram of pooled data from 24 bouts of walking by nine animals, 5–8 s per bout. (B) Step rate is linearly related to walking speed except at very high rates [replotted from Ting et al. (Ting et al., 1994)]. The dashed line is a best fit to the speeds below 35 cm s^–1, and exceeds a step rate of 7 Hz at ∼15–20 cm s^–1 (compare with Fig. 2).
