We study the dependence on the pion mass of the QCD effective charge by
employing the dispersion relations for the Adler D function. This new massive
analytic running coupling is compared to the effective coupling saturated by
the dynamically generated gluon mass. A qualitative picture of the possible
impact of the former coupling on the chiral symmetry breaking is presented.
