RSL, relative stride length; DF, duty factor.
Equations of the form: RSL or DF=aM_{b}^{b}, where M_{b} is body mass in kg.
CL, confidence limits for the scaling exponent, b.
MAPD: mean absolute percent deviation of measured values from the fitted relationship.
Relationships are given both including and excluding data for horses 18-21.
