Fig.1. Effects of speed on cycle (A), stance (B) and swing (C) duration during rat locomotion. Cycle duration decreases with increases in locomotor speed (A). This decrease mirrors the decrease in stance phase duration with increasing speed (B). In contrast, swing phase duration remains relatively constant over a large speed range (C). Vertical lines generally separate data into walking, trotting and galloping trials. However, several slow-speed galloping trials are found between 60 and 75cms-1. Each symbol represents the average values from locomotor sequences at various speeds and gaits. Different symbols represent different individuals.
