[Peculiarities of the locomotion of the Chilopoda Scolopendra cingulata upon changes in speed].
The spatial and temporal parameters of movements of scolopendra legs after instantaneous changes in speed from V1 to V2 double dagger V2 were investigated. It was shown that: (1) the synergy of the walking mode "footprint into footprint" is kept as the locomotion speed changes; (2) the continuity of metachronal waves is not disturbed as V changes; 3) the set of all scolopendra legs within some time after the change in V is subdivided into two groups: (a) a group of fore legs that create a "new" trackway of steps with pace l2 and (b) a group of hind legs that continue following the previous trackway of steps with pace l1. The legs of group (a) walk in the stationary mode corresponding to speed V2, whilst the legs of group (b), in a transient changing mode. The values of walking parameters in groups (a) and (b) differ. Gradually, with a speed of metachronal waves, group (a) reorganizes the function of legs of group (b) from the transient changing to the stationary mode.
