Parameters (slope a, and y-intercept b) for linear regressions of kinematic measures.

<p>Kinematic measures: <i>t_C</i>⁻¹ (inverted contact duration), <i>t_S</i>⁻¹ (inverted swing duration), <i>s_S</i> (swing length), and <i>s_T</i> (stride length). Medians as well as 25% and 75% percentiles (in parentheses) are given. Resultant linear functions relate the parameters to running speed. Significance numbers (sig) refer to comparisons with significant differences between legs 1 to 4 (from anterior to posterior) on the 5% level, i.e. if 3 and 4 occur in the significance column of the 1^st legs, then the differences of the frontal legs to the 3^rd and 4^th legs are significant, but not to the 2^nd legs. For <i>s_T</i> the transitional speeds <i>v_×</i> were 0.28 ms⁻¹ in the first, 0.27 ms⁻¹ in the second, 0.39 ms⁻¹ in the third, and 0.39 ms⁻¹ in the hind legs with much lower increases in the stride lengths of the third and fourth legs than in the anterior leg pairs. In <i>t_S</i>⁻¹ the transitions occur at 0.28 ms⁻¹ in the first, 0.25 ms⁻¹ in the second, 0.2 ms⁻¹ in the third and at 0.28 ms⁻¹ in the hind legs.
