Dear Joachim,
this mailing list may not be the best place to get an answer to your
question.
The JSON-LD working group works basically on the *syntax* of the language.
Instead, the problem you are facing seems to be related to the *vocabulary*
that you are using.
If I understand correctly, your problem is that you would like to express
which sports are practiced at your sport club, but you can not find any
property in https://schema.org/SportsClub conveying this information. Am I
correct?
If I am, then you should rather contact the people at schema.org;
public-schemaorg@w3.org
<http://lists.w3.org/Archives/Public/public-schemaorg> looks like the good
place for that.
best
