How do you play team sports during the pandemic?

I would like to ask you all how you have been playing team sports at school or in your club? Do you have to wear masks during training and during games? Does everyone wear them and do you think that they are effective?

I just find that if we have to keep 6 feet apart, and avoid contact, especially if we are sweaty, then how can you play certain games that unavoidably will lead to physical contact?

It would be great to hear from all of you about your stories, your tips and your thoughts.
