This property is being used by: it:Template:Collegamenti esterni Please notify projects that use this property before big changes (renaming, deletion, merge with another property, etc.)

The database for this property is really large so it includes several people that didn't have this as their main sport or work for pay and some of them werte just doing this sport as a youth. So I think it is not necessary to use this database as a mandatory for including sport (P641) as long track speed skating (Q17165362) and using that as mandatory constraint (Q21502408), and I would also say the same about occupation (P106) for speed skater (Q10866633) and using that as mandatory constraint (Q21502408).
