Change Specific Player's Animations

Is it possible to change which animations play on a specific player when they are walking, running, sprinting, ect.? Like just set it so it automatically loops the animation as it moves so it is just like before, only a different animation? I am making a ‘class’ that runs faster and can charge using the “ACT_HL2MP_RUN_FAST” and “ACT_HL2MP_RUN_CHARGING”, and “ACT_HL2MP_RUN_PROTECTED” for when blinded.
