Using a parametrization of the Wilson loop with the minimal-area law, wecalculate the polarization operator of a valence gluon, which propagates in theconfining background. This enables us to obtain the infrared freezing (i.e.finiteness) of the running strong coupling in the confinement phase, as well asin the deconfinement phase up to the temperature of dimensional reduction. Themomentum scale defining the onset of freezing is found both analytically andnumerically. The nonperturbative contribution to the thrust variable,originating from the freezing, makes the value of this variable closer to theexperimental one.Comment: 25 pages, 5 figure
