Mud Sport reduces the power of Electric type moves by 50%. The effect applies to the entire field.
Most Pokémon that learn Mud Sport are part Ground type and thus already immune to Electric attacks.
When a Pokémon is holding Groundium Z and uses its Z-Power, Mud Sport turns into Z-Mud Sport and raises Special Defense one stage, in addition to its usual effect as above.
