  We study effects of the strange quark mass and of the QCD coupling constant
in the MIT bag model of quark matter with lowest order quark-gluon interactions
on the rapid rotation of strange stars. The influence of rotation on global
parameters of strange stars is greater than in the case of the neutron star
models. We show that independently of the strange quark mass and the coupling
constans the ratio of the rotational kinetic energy to the absolute value of
the gravitational potential energy for rotating strange stars is significantly
higher than for ordinary neutron stars. This might indicate that rapidly
rotating strange stars could be important sources of gravitational waves.
