Abstract
We prove that for , the asymptotic order of the usual Nikolskii inequality on (also known as the reverse H\"{o}lder's inequality) can be significantly improved in many cases, for lacunary spherical polynomials of the form with being a spherical harmonic of degree and . As is well known, for , the Nikolskii inequality for trigonometric polynomials on the unit circle does not have such a phenomenon.
