Groups that promote diversionary activities (6,5)

'groups that promote diversionary' is the definition.
I know nothing about this answer so I can't tell whether this works.

'activities' is the wordplay.
I cannot quite see how this works, but
'activities' could be 'sports' (sport is a kind of activity) and 'sports' is present in the answer.
The remaining letters 'clubs' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
