They are ultimately looking for you to show the things you actively pursue outside of academia and work. It really doesn't matter what you do, its much more about showing you are doing something(s), because ultimately keeping busy will be a transferable skill set, as well the skills you probably develop from those experiences, and also it shows you are an interesting person (e.g. not just a workaholic, because no one enjoys working with a workaholic).
All the things you have mentioned would be things I would include in this. Explain what you do, what responsibilities you have, who you have to work with, and if you have any impact in your interests (e.g. something is better whether it is you, other people, a project, a service etc, for your personal efforts) as well as any prizes, awards, trophies, achievements you may have achieved too.
