Relationships between kinematics parameters and walking speed U. Filled circles and solid lines represent data for bantam leghorns and open circles and dashed lines represent data for large leghorns. The lines of best fit are (A) duty factor=−0.18U+0.79 (bantam) and −0.18U+0.78 (large); (B) stride frequency, fstride=1.51U+0.83 (bantam) and 1.51U+0.46 (large); (C) stride length, lstride=0.36U+0.13 (bantam) and 0.36U+0.23 (large); and (D) swing time, tswing=0.16U−0.22 (bantam) and 0.21U−0.22 (large); and stance time, tstance=0.28U−0.64 (bantam) and 0.36U−0.64 (large). Data points are means±s.d. (s.e. are not large enough to be seen).
