The "relativistic contraction" of skyrmion size in the direction of motion is demonstrated for the "subcritical" case when the skyrmion velocity is less than the spin wave velocity in antiferromagnet. The Lorentz-like "supercritical" transformation for the sizes of skyrmion-like magnetic structures moving with the velocity more than the spin wave velocity in antiferromagnet is found.
