The internal state of an aggregate of a few bound particles and its transformation, when changing from the reference frame, where this combined particle is at rest, to a reference frame, where it moves relativistically, have been considered. It is supposed that the internal state of the combined particle in its rest frame can be considered in the non-relativistic approximation. This internal state is shown to remain the same, when changing from one inertial reference frame to another one. In other words, a particle that is spherically symmetric in its rest frame does not change its form in any other reference frame and does not undergo the Lorentz contraction in the direction of motion of any reference frame with respect to the rest one. A possible application of the results obtained to describe the scattering of hadrons considered as bound states of quarks has been discussed.
