  We review lattice determinations of the charm and bottom quark masses and the
strong coupling constant obtained by different methods. We explain how
effective field theory approaches, such as Non-Relativistic QCD (NRQCD),
potential Non-Relativistic QCD (pNRQCD), Heavy Quark Effective Theory (HQET)
and Heavy Meson rooted All-Staggered Chiral Perturbation Theory (HMrAS$\chi$PT)
can help in these determinations. After critically reviewing different lattice
results we determine lattice world averages for the strong coupling constant,
$\alpha_s(M_Z,N_f{=}5)=0.11803^{+0.00047}_{-0.00068}$, as well as for the charm
quark mass, $m_c(m_c,N_f{=}4)=1.2735(35)$ GeV, and the bottom quark mass,
$m_b(m_b,N_f{=}5)=4.188(10)$ GeV. The above determinations are more precise
than the ones obtained by Particle Data Group (PDG).
