The relativistic quark models study the hadronic systems in terms of the constituent quarks by using the fundamental principles of quantum mechanics. Until now this \nobreak{models} can reproduce satisfactorily the hadronic spectrum using an effective potential of quark confinement. This models can also reproduce the electromagnetic form factors \nobreak{introducing} the electromagnetic current of each quark in the impulse approximation. The mean goal of this paper is to include the axial part of the weak current at quark level in the constituent quark model and then to study the axial nucleon form factor. To improve the reproduction of the data, it is necessary to consider an effective vector meson exchange corrective term in the quark axi...
