Gaining

You probably need to strike a balance you are happy with between being fit and having a bit of a belly.

I would suggest improving on the fitness and then seeing how you feel about the reduced belly.

Don't forgot you can always bulk back up rather quickly so don't worry about a little weight loss

I would guess sports that involve a lot of running or jumping are out. You still have:

1. Water polo
2. Table Tennis (?)
3. Arm wrestling
4. Sumo Wrestling
5. Shot putting
6. Weight-lifting and other strength sports
7. ....anyone?

Fat people can be in shape.

Water polo is knackering! Last time I played it was back at uni, and I was exhausted. I was also terrifically fit (rowing - training 10 times a week).

Strength training, walking... but really just anything you enjoy. No reason why you shouldn't play basketball if you're bigger, and that (can) involve a lot of running and jumping.

I wouldn't recommend distance running though - I'm of the opinion that to run properly requires a good strength to weight ratio if you're not going to get injuries.
