How to plan recurring meetings in scrum How can I deal with recurring meetings (like trainnings or feedbacks) in Scrum? Are they impediments? Do I have to plan less User Stories during the sprint planning? How can I deal with this situations?

If "recurring" means they occur each and every sprint and occupy the same amount of time: just don't plan for them. Your velocity will adjust to the amount of work you get done in the sprint's "free" time. This will be less with more recurring things, but velocity will reflect the work you get done.

If the "recurring" things occur irregular or take different amounts of time. Plan for them just like you would for every other work item. Otherwise your velocity keeps jumping up and down, even if your estimations are perfect.
