              Let $w$ be a non-negative measurable function defined on the
positive semi-axis and satisfying the reverse Hölder inequality
with exponents $0\alpha\beta$. In the present paper, sharp
estimates of the compositions of the power means $\mathcal{P}_\alpha
w(x):=((1/x)\int_0^x w^\alpha(t)\,dt)^{1/\alpha}$,
$x>0$, are obtained for various exponents $\alpha$. As a result, for
the function $w$ a property of self-improvement of
summability exponents is established.
