Based on a simple but effective regularization-renormalization method (RRM), the running coupling constants (RCC) of fermions with masses in quantum electrodynamics (QED) and quantum chromodynamics (QCD) are calculated by renormalization group equation (RGE). Starting at Q=0 ($Q$ being the momentum transfer), the RCC in QED increases with the increase of $Q$ whereas the RCCs for different flavors of quarks with masses in QCD are different and they increase with the decrease of $Q$ to reach a maximum at low $Q$ for each flavor of quark and then decreases to zero at $Q\longrightarrow 0$. The physical explanation is given.
